For the past year I have drastically changed my eating habits (for better if I may say so) and I'm currently training twice a week and doing cardio once/twice per week. However, I still occasionally fall for snacks.
Is there a good scientific reason to prefer one over another. E.g. 50g bag of Lays vs 50g Snickers bar? From what I can see on the wrappings, calories are more or less same. Only difference for me is that chips last longer.
So except trying to avoid them, is any of the categories "more healthy" than the other and why?
