I have been bumping into so much discussion about how to lose weight. Yesterday on the radio, Kirstie Alley said she always ate large portions, was very athletic and had no overweight problems. Then she turned 53, and ballooned up for no special reason. I wrote about her in 2011. She had jumped to 230 pounds from 143…and then she lost 75 pounds, gained 75, etc. The key question is how to lose it and keep it off?

So today I read an article suggesting that you lose more weight from exercise in a warm setting than a cold one, because you eat less after the workout.

The comments are illuminating. One says you can’t lose weight from exercise alone:

I have done a lot of research into clinical trials regarding exercise and weight loss. The general theme is around 25% of individuals GAIN weight with exercise. Another 25% remain weight stable. The remainder may lose paltry amounts…or up to 10-15 pounds…only if sustained. The tale is worse for women.

Exercise has been shown to be fairly pathetic for weight loss. Begin with diet.

Another says you have to do larger amounts of calorie burn through exercise and also agrees that diet is important:

What has been shown to be “pathetic” for weight loss is doing a very small dose of exercise. The vast majority of research studies only have persons exercising about 1-3 hours a week and therefore burning only at most about 200 calories a day. Most dieters in these studies are producing deficits of between 500 and 1000 calories a day- no wonder “diet” looks better. As I quoted below, this study showed that when calorie deficits are matched, exercise brings the same amount of weight loss. Of course the exercise has to be at a much higher dose- at least an hour a day of fairly intense exercise http://www.nature.com/nrendo/journal/v3/n7/full/ncpendmet0554.html

Possibly people who gain weight from exercise are those doing this paltry amount of exercise and thinking they are burning more calories than they are, and therefore they overcompensate by eating too much. Studies also show that at whatever kind of diet that is done, 95% regain all their weight within five years- and low carb diets also don’t bring lasting weight loss. Dieting without any exercise necessitates drastic calorie reduction, which is not sustainable for most people. Exercise is an indisputable factor in keeping weight off. My citation explored many studies which show this. I exercise at least an hour everyday and this helped to lose 100 pounds and continuing to exercise has helped me to keep every pound off going on 5 years.

It’s a huge challenge for most people, especially when most can’t do an intense hour workout each day. But I am still convinced from all I have learned that healthier, low fat/low sugar/low carb diet plus exercise is needed to lose weight and keep it off.
