This is a great comment, and I agree with it. Everything that I hear from experts on weight loss: Cardio exercise is not a major component. Most people are clueless about how few calories that cardio exercise burns. A 5km run burns about 300 calories. People would be shocked to see how little food is it, compared to the amount of effort to run 5km!

Since you said you went through three weight loss cycles (bravo, it is hard to do!), is exercise an important part of the effort? Example: Did you ever try cardio vs weight training? It seems like weight training is the more likely of the two to change body composition (more muscle, same or less fat). And higher muscle weight almost always leads to higher resting calorie burn rate.

Last thing that almost no one is talking about in this discussion: Once you start doing exercise, something changes in your brain. I cannot precisely explain it, but a huge number of men experience a drop is depressing thoughts after starting regular exercise. My guess: Exercise helps to de-stress which has all kinds of other positive impacts in your life.
