Not always, I think that is a convenient myth. Other countries where obesity hasnt been as prevalent dont have higher levels of people with trauma do they?
Countries that didnt have bad obesity rates but are now increasing in overweight and obesity have something in common, a changing food culture, growing more like the UK and more like the USA
It really doesnt take much overeating at all actually to put on a stone a year, I think someone calculated it on another thread as a few biscuits a day (the calorific equivalent of)
And thats another thing that is quite difficult because there is so much investment it seems to 'disprove' CICO, that people really dont understand that you cannot eat more than your calorie requirement and not put on weight, no matter how wholesome and healthy the food is. Believe me Ive been there and done that!
