Exercise and Diet

Some new thinking that exercise isn't a total cure for bad diet. Perhaps that's misleading, but the title of the story is "Why Exercise Won't Make You Thin". Which is sorta true. The idea that you go out to the gym and exercise for 3 hours a week and lose weight, well maybe you'd lose weight, but it wouldn't be due to the exercise per se, its due to the fact that you are supposed to eat less in combinatino with exercise. Its like this. If you consumed 10,000 Cal in a week, and wanted to lose weight, you could cut your intake to 8000 Cal, and not exercise. Or you could burn 1000 Cal and exercise.

The point (and a major point of the article), is that people tend to overcompensate. I know I do. I exercise, and wolf down a burger, or a shake. Unless you are a sports physiologist, you have no idea how many calories you just burned. And you shouldn't feel like you need to replace those calories.

This is one reason why biking is an extremely effect weight lose strategy, but it boosts your metabolsim so much that its quite easy to double your food intake and not really notice. Exercising on a bike burns 250 to 1000 Cal in an hour. When i did my 40-60 mi trips, i would burn at least 2000 Cal, probably close to 3000 Cal. That's a full days worth of food assuming basal metablism. So, the idea was I could eat perfectly normally during the week, go on a long bike ride, eat normally that day (that's the hard part), and burn a pound of fat.

Anyway i'm getting back into shape slowly. I noticed my weight hasn't changed much but I lost a good deal of muscle since i left Houston.

On the "Tour" it was stated that those bikers burned up to 10,000 cal/day uphill.
