After reaching the border of obesity, I have learnt to become sensitive about calories, sugar and cholesterol contents in any food I buy. It is not that I have been successful in giving up all the junk food items but still, this knowledge about calories, sugar, salt and fat is surely good. The best part is that if one day, I eat some heavy foods then the next day, I try my best to control my appetite.
Well, a new study has questioned this matter: Nutrition facts label does not help curb obesity epidemic
At the end of the day, it is up to you as individual person that how you are going to use the knowledge derived from nutrition facts label. I have stopped eating some junk food items like crisps and French Fries.
