Here is my theory on obesity and overweight. 
In the USA starting in about 1980 the USA (5%) of the world population had more air conditioners than the rest of the entire earth population.
The numbers of course have increased in the USA as well as other places.
When it's hot and there is no relief, you don't want to eat. It's pretty much a fact.
But sitting in an air conditioned, nice cool room, you can eat all you want.
Give it some thought. It's my theory.

 When it's hot one also doesn't like to indulge into fat-burning activities (although the alleged baby boom after the big blackout in NY in 65 would prove the opposite 
 )


 ). Yoghurt contains the sort of bacteria we need and helps us restore the normal bacterial flora in our digestional system. These "good" bacteria, our symbionts, keep the bad guys at bay. And also forget about the much advertized "probiotic" yoghurt - that's just another advertising trick. Plain standard one is just as healthy at half the price.
