In a hot environment you'll just use more salt and water, which will put an end to the exercise much sooner if you're not paying attention to your liquids intake. Your performance will not actually suffer until it's hot enough so the cooling effect from the sweating doesn't suffice to keep the body temperature constant. Same on the other end of the scale, as soon as it's cold enough to actually make you cold under the skin despite the exercise. But you'll get other side effects like breathing restrictions long before that happens.

Extra energy expenditure for keeping warm is just not (relevantly) there when you're exercising - you generate plenty enough heat from what you're doing there. If you aren't physically active, and you start quivering from the cold, then your muscles are working only for the heat.

I weigh 205 pounds and have an estimated 17% body fat(yikes!).
My plan is to get down to 10%. I need to lose about 15 pounds of fat to do this.
15X3500=52,500 calories.

Damn I better watch what I eat lol

17 percent isn't WAY off for a male. 10 percent is really lean and mean.

The actual amount of calories you need to burn to get rid of the fat is actually DOUBLE the energy contained in the fat. As I elaborated above, you'll never burn fat alone, it's always at least about half carbs. So if you want to burn of 50 Mcal of fat, you need 50 Mcal of carbs as well. That's the (at first sight) perverse nature of getting fit - you need to eat MORE not less (just not more fat - more of the right stuff). And exercise lots.

Seems like a lot I know, but 15 pounds is a relatively modest amount of weight to loose compared to some poor souls who weigh like 250+ pounds. So you need to burn an extra 52500 calories. . .break it up into intervals of 500 calories per day and it would take only 105 days. Assuming you have found your equilibrium (you are not currently actively gaining weight and know how much you can eat without gaining or loosing) eat 250 calories less per day and exercise 250 calories worth each day. On days when you don't get to excercise (because lets face it. . .sometimes you just need time to rest) just eat less instead. The nice thing about regular exercise is, the more muscular and fit you become, the more calories your body has to burn naturally to sustain itself! It is very easy to shave 250 calories off your daily diet because many people do not even think of the caloric content of a lot of things they eat and do not realize how quickly "just one cookie" here and there adds up. Switch to lowfat dairy products if you eat dairy, and use artificial sweeteners if you must eat sweets. Instead of the Big Mac, have the salad for lunch and eat whatever you normally would the rest of the day. Try to eat foods that are healthy and have high volume (make you feel full) but don't have many calories. For instance, eat an orange at breakfast instead of drinking orange juice because the juice is concentrated calories and doesn't stick with you as long as the orange will. Don't let yourself get hungry to the point of "I'm starving" or you will over eat. Eat something whenever you feel hungry, don't ignore what your body is telling you. Just choose wisely what you eat. One major key for anybody undertaking weight loss is to monitor and find out just how many calories per day your body needs to function as you normally do without gaining or loosing any weight. Once you know this, it is much easier. It takes discipline and a general change in a persons attitude toward food but it is not as hard as people think (provided you don't have any medical conditions that keep you from loosing weight . . .) Once you start to see results, it becomes easier to keep it up because you see it working. Just stick with it a few weeks and you'll see change.

[EDIT] Oh, this was in reply to Genx87. Next time I'll use the quote button:

Be careful with low fat options... a recent report stated that low fat mayonnaise has half the fat but three times the sugar content of ordinary mayonnaise. (not that you should be eating much mayonnaise)
Low fat cottage cheese seems to be another example - (half a cup portion)
ordinary cottage cheese 4% fat - 110 Kcalories
reduced fat cottage cheese 2% fat - 100 Kcal
Low fat cottage cheese 1% fat - 80 Kcal

10% is lean?? During basketball season, a friend of mine and I were below the scale on this electric body fat measurer... that's less than 5%.

EDIT: Oh yeah, so what does that make me... dead?? :confused:

I don't think those are particularly known for accuracy.

The electrical ones measure resistance between leg1 and leg2, and guesstimate water/protein/fat percentages from there. This is horribly inaccurate - men's bellies usually accumulate further up where this measurement doesn't even go, skin moistness and salt, general (de-)hydration levels, well, just forget WHAT these things display. They are useful to track progress when you're using it under reproducable circumstances (e.g. every morning before the shower), but the absolute numbers they give are plain useless.

Nonetheless, it is possible to have low body fat and live - world's best handful of pro cyclists dips deeply below 10% when they build up for the Tour de France.

Things start to get unhealthy when you're not getting to that low body fat by high fat expenditure, but by way too low fat intake. Several bodily processes, including important stuff like vitamin ingestion, require fat.

So if you have a "worryingly" low body fat level but solid fat throughput (ingest-burn), then things are fine. For men. Women risk hormonal problems when they're below approx. 20 percent.

the most accurate method involves weighing yourself in a pool. Not easily done.

I think the skinfold technique might be the next most accurate, but I'm not sure...

If you want to cut calories, one thing you can do is use 5-carbon monosaccharides instead of Sucrose. Also known as Polyols or Sugar Alcohols. My favorite is Xylitol. Even though the stuff you buy is synthesized, it's natural chemical that can be found everywhere from appls to your body (which makes it) to birch bark. It actually prevents cavities because bacteria attach to it because its structually similar to sugar, but they can't digest it. Also why it's found in Xlear nasal spray.

Completely free information. They have no financial gain from it.

also completely free, but with considerably less hype:

A total of 160 participants were randomly assigned to either Atkins (carbohydrate restriction, n=40), Zone (macronutrient balance, n=40), Weight Watchers (calorie restriction, n=40), or Ornish (fat restriction, n=40) diet groups. After 2 months of maximum effort, participants selected their own levels of dietary adherence.
<snip>
For each diet, decreasing levels of total/HDL cholesterol, C-reactive protein, and insulin were significantly associated with weight loss (mean r = 0.36, 0.37, and 0.39, respectively) with no significant difference between diets (P = .48, P = .57, P = .31, respectively). CONCLUSIONS: Each popular diet modestly reduced body weight and several cardiac risk factors at 1 year. Overall dietary adherence rates were low, although increased adherence was associated with greater weight loss and cardiac risk factor reductions for each diet group.

Interesting...

In Dember of 01, I weighted 240lbs. I subsequently lost 60lbs in 6 months, After becoming a vegan vegetarian, with little increase in exercise. Someone do that math for me! that sounds like a ALOT of calories to have burned... and in a short time.

I now weight 165, and eat about 1700-2000 cals a day and have for a long time. The interesting thing here is that a 24 year old, male living a non sedentary (light/moderate activity) lifestyle, All my research says I need alot more then 2,000 cals a day. Infact, I have been slightly gaining weight for the last 6 months probably about 5lbs worth wich I believe is mostly fat and no muscle. Yet its VERY rare that I eat more then 2000 cals a day. According to my food log I average 1950 Cals a day. Over the last 6 month period.

I do eat a relatively low fat diet, I also consume less then 7g of saturated fat per day on average as well.

According to the math though, I shouldnt be gaining weight right? yet it happens? so... me being weird aside (wich shouldnt effect the math) how could I be gaining weight again if I'm supposedly way under the my required basal calories per day.?

It all depends on your metabolism rate, and that depends on lots of things. I find my metabolism is really high when I eat more.

A good measure is how warm you are. If it is like 65 in your house, you're wearing just long pants and a sweatshirt, it is easy to tell when your metabolism goes down; your hands get cold. That's my measure :)

joe, the body adapts.

If you undersupply for extended periods, you'll lower your metabolism rate, and lose muscle tissue, thus, your energy requirements go down. Vegan diet, with its typical risk of undersupplying proteins, will accelerate the loss of muscle tissue.
Then, with a slow metabolism and all disposable muscle depleted, weight will start to creep back up as your body has been accumulating fat all through that "starvation" period. Extremely low-fat diets accelerate that process, simply because it forces the body to fire up its (otherwise rarely used) fat synthesizer.

according to my food log I avg 65g of protien daily, from multiple sources, that is right in line with everything I have researched. When I do heavy exercise I try to increase my intake to 100g. A vegan diet is in my opinoin no more at risk of undersupplying protiens as many others risk 'over' supplying, (do some research, scary information is comming to light in the post atkins boom) Of course any diet can be abused or mis-managed.

I'm stronger now then I ever have been so i'm not really certian I've been losing muscle mass, at least it wouldnt make sense...

btw my hands get cold easily always have, and my average body tempature is 96.4F I always wondered if there was a correlation there...

Certainly a pointer to a slow metabolism. Yes protein overkill is extremely unhealty - this is long known, yet in the "Atkins" craze no-one would want to hear that. Health? Ah, thanks, I'll have the rapid weight loss instead.

The problem with protein intake on a vegan diet isn't so much the amount, but the kind of proteins you get. "Yours" aren't as useful to the body as animal protein would be. (As soon as I remember the english translation for the phenomenon, I'll point you to some literature.)

You might be thinking of methionine? Met isn't as plentiful in plant protein as it is in animal protein, so some vegans might see a deficiency. There are (or can be) similar issues with vitamin B12 and maybe carnitine.
