Could less equal more for exercise?

Recent studies have demonstrated that it may be possible to achieve more weight loss with shorter exercise sessions. The studies compared equivalent workout levels (each burning 600 calories per hour) with different lengths of workouts (one group worked out for 30 minutes and the other, 60 minutes). Normally, we associate more calories burned with more weight loss. In this case, the opposite happened: the 30 minutes group lost 20% more weight than the 60 minute group. One suggestion as to why this may have been the case is that the group with the shorter workout tended to be more active throughout the day. They also considered the fact that the 60 minute group simply had less energy after their workouts, and therefore their cumulative calorie burn over the course of the day would be less. In my opinion, this is probably the most likely explanation. Fat storage is zero sum: you can only store from what you have extra. If you eat fewer calories than what you burn, then you burn up

Can chemicals in our food cause obesity?

The science isn't there yet, but one thing is for sure- BPA enters your body and is finally excreted. My suggestion is to follow the guidelines as best you can to ensure that these foreign toxins do not get into your diet regularly.
