ethan with respect its not as simple as eat less, move more. my mate has had a battery of tests which deduced that he cannot digest carbs effectively, despite eating a low fat diet and exercising 6 days a week, he could not lose weight, he went through the usual "oh you must be eating junk" and the very unhelpful "you have to lay off the pies" and the wonderful "eat less,move more" mantra
reducing his intake of simple sugars has resulted in 2 stone weight loss that has been effortless, he is still going but his portion size remains the same, he has just changed the carbs to protein and a smaller amount of complex carbs.
