[quote:fce583c8c1="chalked4dyno"]Also, it has been discovered that your body will put fat on when you have a food allergy.
[i:fce583c8c1]Water retention, or edema, is particularly common among food allergic individuals and is an important contributing factor to obesity. The removal of an offending food will often result in a rapid water loss of five to ten pounds within a week’s time, all without the use of a diuretic.[/i:fce583c8c1]

EDIT: The above is a quote, which I seem to have screwed up.
My life story.
I'm alergic to most good sources of protein:
fish,egg whites,beans (soy included!),nuts,milk.
I'm also alergic to pork, leaving me with red meats and poultry.
I'm also alergic to:
Lettuce, strawberries, sesamme, sunflour, flax, yeast, mushrooms, mustard, apples, pears, pectin (which is in pretty much all fruit..I think..).
The only fat I have on my body is on my stomach. I have some decent sized abs underneath, but their coated in a solid 2 hand-fulls of fat!
I can't blame this totally on my alergies, but I'm sure it plays a good part.
My uncle lost 20 pounds an a few inces off his waist within a month or two of cutting out the stuff he's alergic to.
It's REALLY hard to go through a day without eating something I'm alergic to. They throw soy and modified milk ingredients in everything these days, and I don't have time to cook everything from scratch.
When I do try to eat 'heathy' I end up feeling tired and hungry... After reading this, I have a better Idea of what eating healthy is.
Another thing is aerobic excersise. I have bad knees and was told by my doctor not to run. (not that I ever really did.. it just hurts too much!). Biking is ok, but I could buy a whole trad rack for the cost of a bike, so that's not gonna happen!
Any suggestions on cardio that's easy on the knees or advice on dealing with my totally screwed up dietary requirements would be greatly appreciated.[/quote:fce583c8c1]
Intresting thread, I've started doing yoga a couple years ago and have since gotten more into. I've also learned more about the "yoga of dieting" and this has helped me a great deal.

In reply to: ...he built about "20 pounds of back muscle in two or three months" I was wondering if that was realistice, or if the guy was probably exagerating, or what your take on the statement is. thanks.
He's exaggerating.

You don't need a $2000 bike to get aerobic exercise. Get a $200 bike, or $100 used bike.
In reply to: Any suggestions on cardio that's easy on the knees
Swimming. I also strongly suggest that you start taking glucosamine sulfate supplements religiously, if you're not allergic to them, for your knees.
In reply to: advice on dealing with my totally screwed up dietary requirements would be greatly appreciated.
I'd suggest that you consult with a registered dietician. It sounds like your dietary requirements are unique.

confession time, I decided nine months ago that my belayer needed a break and that my strength (not to mention my confidence) needed a boost. I combined Weight Watchers (yeah yeah, i'll try not to be a walking advert) and The Work Out from Hell (and hell it is). Took advice from a personal trainer friend on mixing the two (i.e. what to eat/ when to eat, eat half my bonus points on the days I do a heavy workout etc). Managed to lose 30.5lbs (that .5 means a lot to me, put me over the two stone lose, happy days). Don't get me wrong at the beginning I felt a little tired, but my body got used to it, and I've never felt stronger. I've started leading which a year ago I swore I would never do. So it can't be that bad, even if it is just a head thing. My head now believes I'm stronger, and has a little trust in my body, which ain't looking too bad either (in comparison to nine months ago).

Last summer I tried a technique that worked wonders for me and it does not involve alot of calorie counting or work outs from hell. It grew out of a conversation with a personal trainer other climbers and after several diets that don't work.
I started with a few facts. 1) Weight Lifting, Running, walkiing, and most other "normal exersize" programs burn around 495 calories an hour. The great news is rock climbing is 785 an hour! (colriecounter.com firgured at male at 174lbs). With a 200 ft climbing gym here climbing became the base of my work out. :D
The trainer taught me how the body burns fat. The body burns fat inside the muscle first then looks for other reserves. (ie: Buldges).
The last fact to keep in mind: You have to relate your food intake (ie: types of food-protien vs carbs) with your planned activities and eat the fuel you will need 2 hours before you need it.
The first step was to find a good internet calorie counter. They give you a calorie count based on your weight sex and the time you spend doing that activity. I always use moderate level for figuring my numbers even though I know my workouts often are harder than that. 1) Figure out how many calories you burn just being alive. Look up activities like working, driving to work, sleeping, watching tv, etc. 2) Then figure per your weight your work out regimine. Climbing, walking, running, stretching, etc. 3) Then find out what your food intake is. Stay with the foods you love. (I lostweight eating Mexican food!) THe only diet change i made was trying to eat more whole foods and stay way from processed sugar. (i.e I gave up sodas) I ate my heaviest meal in the morning lighter at lunch and a snack for dinner. No sups only a daily multi vitamin and pre-digested protien. (2 Table Spoons before bed after a heavy work out day.)
Once i know my numbers and know my diet and routine I didn't count anymore and never kept up with points! I just stayed with the routine. My work out was based on climbing so I looked forward to working out. (a cute partner helped!) Dieting was easy because I was eating what I enjoyed eating anyway. This made this an easy program to stay on for a long time.
Ok now to the good stuff! I had an insane partner one summer. She would run 3 miles before coming to the gym for a 2 hour climbing work out. Being more sane I streatched at home working every muscle group. When I streatched my sides I used a surgical cord so there was a small amount of resistance. I did pull ups on a home pull up bar set in my bedroom door. I put my feet on a chair this didn't really add to strength it just warmed me up for the gym. Same with dips (on chairs) push-ups and a set of incline sit-ups. Not to the point of any fatigue just enought to loosen up and start a fat burn inside the muscle. (burned about 300 to 350 calories)
We worked out 3 times a week staying on long 5.6 to 5.8 routes. For 2 solid hours I was either Belaying or climbing the entire time. (This Burned around 1800 calories.
Due to injuries, I can't run so I would walk 2.5 miles after the gym took about 40 min. I also did my streatchign routine again just before bed. (burned about 400 calories)
On the heavy work out days staying on a 2000 calorie diet I had a 1300 calorie deficiet 3 days a week.
On non gym days I did the same work out described at home. I walked 5 miles (took about 70 min. 450 calories)
On light days I burned just a little less than 2000 calories. No surplus more than 200 calories.
Diet wise I only remembered to not eat carbs on my light days and eat anything I wanted on the heavy days. Basically protien when i wasn't exersizing. More carbs when I was working like an idiot.
Weekends that I went climbing were a bonus burn hiking and climbing and building anchors the better part of 10 hours. And found out I was only eating 1200 calories on those days.
I wasn't obese when I started but at 174lbs I had had a gut and a little flab. I didn't loose weight on the scales but went from a 48" waist to 34". Chest and shoulders went from 34" to 37" Arms tightened up you could actually see my triceps and quads during the climbs. And the girls said you could start seeing my jaw line again.
The only down side was the amount of time I spent workign out. In my situation going to the gym was a hobby and where I met up with most of my friends. So it was easy to stay on this for me. You do have to love your workouts to put this much time into it.

If your sceptical about diet and excercise working, check out this website:
http://www.johnstonefitness.com/all/front/w.php
this would also be one of the best motivators to keep on your diet/exercize regime, take a pic of yourself everyday in your undies and post them on the internet. tell all your friends about it if your brave enough!!!
Just one thing about soy. I have heard it said that eating too much soy products can be bad for you, but is this true? I read a nutritional book called "The Okinawan program" which looks at the diet of the people of Okinawa, who are the longest living people on the planet. Apperently their diet constists of about 10% soy products. So why isn't it affecting them?
Just some thoughts.

First of all, great thread, thanx to Jay and all for the information.
Second, I have some questions regarding my own strategy for weight loss, which is basically just something I dreamed up with not much research on the subject. Until a recent tail off, which prompted my questions, my strategy has been extremely effective.
My plan was based on the following assertions:
1. To lose weight, I need to burn more calories than consumed
2. I can "prime" my body for fat burning by timing my meals and exersize sessions properly - so my fat burning workouts will be more effective when my body is "primed"
3. I need to consume the fuels that suit the particular activity I am engaged (or planning to engage in). - roughly speaking I try to eat high carbs before anaerobic, and high protein/moderate carbs after anaerobic
My implementation of this is probably quite idiotic. Basically I prime my body to burn fat by eating nothing until my daily run at 11am. I run 6 or 7 miles (about an hour) every weekday. Then I eat some beans and a turkey sandwich (mustard) for lunch. After work, I go home and begrudgingly (for fear of bodily harm) eat what my wife prepares, usually something really bad, like spam, or something equally terrible.
Tues/Thurs body weight strength training (pull/situps) and Sunday all day climbing.
Im 5'5", and 34 yrs. In Jan of this year, I weighed in at 205 (im a fairly muscular person, so i don't look as fat as this sounds), and now I weigh 158, but I've weighed 158 for about 6 weeks, all the while sticking with my routine. I still have some fat around the midsection i'd like to shed - but it seems to be very sticky.
Is there any merit at all to this fasting before my run? Everyone says never skip meals - but it seems to be because it makes you hungry or not take in enough calories. I take in plenty of calories daily, just at strange intervals. I have to wonder how I have plateued like this when my calorie intake is still in defecit. My guess is that Im still slowly losing fat, but I also do Tues and Thurs strength training - so mayb e muscle building is occuring and it offsets my weight loss due to fat loss. Though, this is confusing because I was certain that under calorie defecit, no muscle could be built. My strength training was to attempt to minimize muscle burning in my weight loss endeavor.
Any advice is appreciated!
Cheers,
-Mike

(1) is essential, (2) is wrong, and (3) is probably helpful.

Skipping breakfast is probably counterproductive to your overall goals. The reason is that overnight, as your body's stores of carbohydrate diminish, your body starts to break down muscle protein, which it uses to produce new glucose. This continues until you eat some carbohydrate in the morning. If, instead, you eat breakfast, it is true that you will burn less fat (and more carbohydrate) on your run; however, later in the day, your body will draw from its fat stores to make up your daily caloric deficit. In other words, about the same amount of fat will be burned either way; only the timing of the fat burning will differ.
In reply to: I run 6 or 7 miles (about an hour) every weekday. Then I eat some beans and a turkey sandwich (mustard) for lunch.
That's probably a good mix of carb/protein. If you want to optimize your muscles' uptake of carbohydrate and amino acids, however, consume a fruit shake containing a protein powder supplement within an hour after your exercise sessions. Just make sure that you reduce the size of some other meal to compensate.

In males, the fat around the midsection can be tenacious.
In reply to: I have to wonder how I have plateued like this when my calorie intake is still in defecit.
How do you know that it is? How many calories are you consuming and burning daily, and how did you arrive at those figures?
In reply to: My guess is that Im still slowly losing fat, but I also do Tues and Thurs strength training - so mayb e muscle building is occuring and it offsets my weight loss due to fat loss.
Could well be. Check how your pants are fitting over time, or have your body fat professionally measured at time intervals.
In reply to: Though, this is confusing because I was certain that under calorie defecit, no muscle could be built.
It can be, but the diet must be low in fat, and high in both protein and carbohydrate. That is sort of the point of the diet I recommend in my initial post.

So my attempts to maximize fat burning during a daily aerobic session by skipping breakfast actually works - but it's a counterproductive strategy because I will metabolize muscle tissue during sleep? I did not know this. My original assumption was that the slow steady energy burn during sleep was mostly fueled by fat stores (ie the fuel determined by the nature of the "activity" it fuels)- so that in the morning, my body is already in a "fat burning mode" - which is what I was trying to capatilize on for maximum fat burning.
In reply to: In reply to: I have to wonder how I have plateued like this when my calorie intake is still in defecit. How do you know that it is? How many calories are you consuming and burning daily, and how did you arrive at those figures?
Well, I don't actually count very accurately. I figure I need around 2500 to maintain my weight, except I burn about 650 on a 10k run every day, so I need around 3100 actually to break even. My lunch is about ~800, then a ~1200 meal, then between my meal and bedtime I consume 500 or 600 more in granola or cereal. I should probably start monitoring that more closely.

That's encouraging news. I had been very worried that I would lose too much muscle mass while attempting to lose fat - and my strength would go down. It may have a bit, but without a doubt, my climbing has improved. But this will provide new motivation as it's easier to do sport specific strength training when you hope to _gain_ something by it - not just doing it to break even!
Thanks for the response, Jay.

Your body must maintain a minimal level of blood glucose at all times because your brain needs glucose; it can't access fatty acids for fuel. Overnight, this glucose comes from glycogen stored in the liver. As this store is depleted overnight, the body begins manufacturing new glucose from its protein "stores" -- muscles. Consuming carbohydrate in the morning provides "fresh" glucose to the body, and so the body stops breaking down muscle protein for glucose.
Don't worry about how much fat vs. carbohydrate you are burning during your runs. It doesn't matter. As long as you are not in negative protein balance, and you have a deficit in total calories, you will lose body fat. You must because there is no other source of fuel to burn to fuel the calorie deficit. Even if you burn all carbohydrate during your run, you must burn fat later because when you consume your next carbohydrate meal your body must use some of the carbohydrate to resupply the stored carbohydrate you burned during your run. Since carbs are being shunted from energy use to the resupply of carb stores, the body has to burn something to keep you alive. Since we've assured by a properly chosen diet and exercise plan that we are not in negative protein balance, then the only thing left for the body to burn is fat.

You may be slightly overestimating your daily caloric needs. Your actual caloric needs could be as low as 2500 kcal/d, including your runs. And, I agree that the way you monitor your calorie intake is too blunt. Reread my first post in the thread for my suggestions on how to monitor calorie and protein intake.

jt512,
Thanks for your valuable input. There's so much "stuff" out there on nutrition that it's nice to see some quality information based on the literature instead of pseudoscientific hypothesis.
I'm looking to keep up on nutrition for use within my practice. I don't have time or desire to wade through volumes of studies. Could you recommend a journal(s) that are most valuable for useful information. I studied under Dr. Joel Pins from the U. of Minnesota and I cannot remember what resources he recommended to stay up to date on clinical nutrition.
Thanks. I have been thoroughly impressed by your comprehension and simple delivery of information on this board. I hope that people understand how valuable it is.

Just thought I would throw in my 2 cents on the topic. I have some experience in the subject (Masters degree in Exercise Science) and a few years working in the field.
I usually try to keep it simple for people, there are not many people out there not willing to count everything they eat (me included). If you eat like the typical american you can probably lose the weight by just getting rid of the processed junk (SUGAR, high fructose corn syrup or the million other code words they use for sugar) also eliminate all hydrogenated (partially hydrogenated oils from your diet). Eat foods with as few ingredients as possible is a good way to start, if you look at the back of a box and the ingredients takes up half the box, it is probably not good for you. Limit you saturated fat intake, however, not all fat is bad. you need to get in your omega 3's and other monounsaturated and polyunsaturated fats.
A rule to live by IF IT IS WHITE DON'T EAT IT (except maybe chicken) If it is white (white bread, white rice, ect.) Some genius decided to take all the healthy stuff out of the food and give you some thing that is basically worthless for your body. EAT WHOLE FOODS!!!!!!!! Like your mom said eat your fruits and VEGGIES!!!
Losing weight takes time, The faster I see people lose weight the faster I see them put it back on.
Your body tries to maintain a certain body weight, this is why you can eat less and still not lose weight. Your body will slow itself down, basically it thinks it is being starved. So if you just drastically reduce your food intake your body is going to fight you the whole way. You have to do it slowly and smartly. Spread your meals out throughout the day (4 meals 2 snacks or something) remember you must eat less at each meal if you are going to increase the number of meals you are eating. Then continue to exercise the combination is very important. reducing your food intake slows metabolism so you must exercise in order to keep your body burning calories.
Your body will protect the muscles that you use the most, it will steal protein from the muscles you use the least. So if you are climbing a lot, it will probably not take from you climbing muscles. Your body will protect what it thinks it needs and if you use a muscle all the time it will try not to weaken that muscle. This is unless you are on some crazy calorie or protein restricted diet, then it will only protect vital organs.
Example: when I started training to run marathons after years of training to get big for football, I lost a lot of muscle from my upper body (muscles that were not used as much) and basically no loss from my lower body. This was helpful, there was no need to carry around all that extra muscle mass for 26 miles. I have dropped 20 lbs of muscle since my playing days, I could not imagine what it would be like to haul that extra 20lbs up a rock, I only kept the muscles I need.

if, for example, i eat 6000 excess calories in one day, am i more likely to gain more weight or less weight or the exact same amount as if i just ate, for example. 400 excess calores every day for fifteen days.
by excess, i mean more than is burned by my body.
also, how rapid is the transformation from excess calories to body fat?
i.e., if i eat exactly 1200 more calories than i need in a day, will i gain exactly one third of a pound of fat as soon as those extra calories are digested and processed (a day or two)?

To a first approximation it doesn't matter whether you eat all the excess calories in a day or spread them out over time. Excess calories are excess calories. If they aren't turned into fat, where would they go? They can't just disappear.
In reply to: also, how rapid is the transformation from excess calories to body fat? i.e., if i eat exactly 1200 more calories than i need in a day, will i gain exactly one third of a pound of fat as soon as those extra calories are digested and processed (a day or two)?
"Exactly" one-third a pound of fat in a day? Not necessarily. In the short term (a couple of days), you might store a little of the excess calories as glycogen, the body's storage form of carbohydrate. But the body has lmited ability to adjust its carbohydrate stores, so you can expect that almost all the excess calories will be stored as fat more-or-less immediately.

As a first contribution to this thread, it would only be appropriate to start by saying thanks to jt512 for all the effort. For what it's worth it has been both interesting to read, and helpful.
But... I have a question. To what extend do you think the use of thermogenic type supplements are able to contribute to a weight loss program, and to what extent do you think they are healthy? I suppose that's two questions, but I also want to suffix this by saying that I'm not so interested in the more serious ephedrine/amphetamine type supplements, rather the more legal and accessible over-the-counter varieties.

I haven't seen data on the effectiveness of thermogenic supplements. I suspect that if you can tolerate them, then they will be effective, not so much because they are thermogenic, but because they suppress appetite. But you do have to be able to tolerate them. I've experimented with them myself, and even at half the manufacturer's recommended dose, make so edgy that I can't concentrate. In reality, they are unnecessary. You can lose weight without them.

So could you suggest a meal plan that would empasise the the chartristics of your strategy, another thing could you plan it as a vegitarian meal plan

Unfortunately, I don't really have the time to go into that level of detail. I think that I provide adequate guidance to food choices in my first post in this thread. The challenge for a vegetarian using this approach is to find sufficient high-protein foods. The best sources are non-fat, soy-protein-based mock meats; legumes; egg whites; and non-fat milk. You will likely need to supplement your diet with protein powder supplement, as well. I had no problem following this diet when I was consuming a vegan diet.

In reply to: In reply to: if, for example, i eat 6000 excess calories in one day, am i more likely to gain more weight or less weight or the exact same amount as if i just ate, for example. 400 excess calores every day for fifteen days. To a first approximation it doesn't matter whether you eat all the excess calories in a day or spread them out over time. Excess calories are excess calories. If they aren't turned into fat, where would they go? They can't just disappear.
This is probably an ignorant question, but couldn't some "disappear" in the form of waste? If I grossly overeat on a holiday (as I'm prone to do), why would my body store all those excess calories? Couldn't it just dump some of them?

In reply to: So much for case studies. Numerous controlled research studies have shown that extreme diets do not work in the long run. You can lose weight in the short-term on Atkins. The question is can you keep it off? I've yet to see anyone who has. Atkins is no different than any other extreme diet. Research has shown that nearly 100% of those who successfully lose weight on such diets gain all the weight back within two years. The only way to lose weight permanently is by modest caloric restriction and increased physical activity followed by dietary vigilance after your target weight is reached. -Jay
Yeah...at my work, basically all of the guys over age 35 have been/are on Atkins. They all love it. They all lose weight. They smell funny when they're doing induction. And they ALL gain it right back, because they don't exercise and they simply eat too much. I'll let you all know when the first Atkins-induced heart attack happens.
My uncle (and active, healthy man who cycle-commutes) wanted to lose weight, so he
a) eliminated the flavouring and packets of sugar in his coffee
b) went from whole to 1% milk
c) walked up and down the stairs of his 5th story lab.
He didnt notice the missing stuff, was losing about 1 lb/month, and has kept it off no problem.
I have a question for Jay-- why are some people (like me) unable to gain weight (and why is it so easy for others)? I do about 4 hrs heavy cardio and 8-12 hours climbing per week. I eat probably 5 meals per day and I snack constantly. I eat lots of veggies, lots of bread and trotillas, some meat, and little processed or fatty food. When I stop exercising, my appetite stays quite high, but I cannot gain weight. it doesnt matter what I eat, or how much, I can't gain weight.

Yes and no. First, when you eat food, it isn't really in the body when it's in the alimentary canal (the stomach and intestines, basically); it's in the body when it has been absorbed from the alimentary canal. Any food that isn't absorbed from the alimentary canal is eliminated as part of the feces. We don't absorb 100% of the theoretically absorbable calories we eat (but it's close). If we grossly overeat it is plausible (though I've never seen any studies of this) that we could overwhelm our body's ability to absorb the food we eat and that, therefore, we would absorb a smaller fraction of what we eat. So, that's one way that, theoretically, some calories could be "wasted." However, once we absorb a meal from the intestines, I am aware of no metabolic pathway that allows for partially metabolized food to be eliminated from the body; in other words, once you've absorbed it, you have to either burn it or store it. We do, though, have some ability to "waste" energy when we overeat. This is known as adaptive thermogenesis. If you ever notice yourself feeling really warm after a large meal, your body is likely wasting calories by just burning them off, creating heat.

I don't know for sure. It is thought (or known, maybe) that individuals differ in their capacity for adaptive thermogenesis, that is to change their metabolic rate in response to over- and under-consumption of calories (see also my last post). For better or worse, you may have a large capacity for adaptive thermogenesis.

I'm certainly no expert, but I wanted to chime in to share a study I read about a couple of years back. In the study a group of people ate 10 lbs of excess food per week for a couple of months. Their weight gain was measured, and at the end of the experiment it was found that some of the volunteers gained a lot of weight, while others only gained a couple of pounds. The doctors observed the differences between those who gained a lot of weight and those who didn't, and found a strong correllation between weight gain and the nervous tendancies of the individuals. Apparently, people who exhibit nervous energy by fidgeting, tapping, twitching, pacing, etc, do not put on weight easily. So I guess that's another mechanism for burning excess energy. I guess you could say it's a high idle.
I also wouldn't discount the brain's ability to burn calories. I've heard that the brain is responsible for 30% of the body's total energy expenditure while at rest. I took a day long standardized test a couple months ago and found that I was very hungry all that evenening and the next day as well. I'm guessing that was due to a combination of stress and increased brain function.

I am proud to say that I just passed the 20 pound mark on my weight loss. When I finally got my "dream job" I quickly realized that sitting a desk all day was less fun than it sounded in college and gained a lot of weight. When I finally built up the courage to weigh myself, I woke up and started shedding the pounds. No fad diets, no gimmicks, just discipline and self-denial when it comes to stuffing my face. To everybody wanting to lose weight: Burn more than you take in! That is all you need to know. To keep it off and get stronger, you will need to learn more about nutrition, but start somewhere like putting down the fork and getting off your butt.
Climbing may not be the best exercise by which to lose weight, but it can be one of the best motivators to lose the weight.
