'A calorie is a calorie.'

The caloric value is the same, but the nutritional value is different. This is the truth. If one were to consume 10,000 calories a day in "healthy" foods and not do a damn thing with it, that person would still be a fatass. To state otherwise seems ridiculous. Of late I have seen and spoken with a couple of fellow oldsters that were riding electric bicycles.
They said they were doing it for health reasons and because it was fun. I asked if they ever pedaled the bike and both said "the bike does the pedaling!". This is the same mindset that feeeeels that a calorie is not a calorie, in other words, they are wrong.
Eat well, train hard and if you are fat, cut back on the calories and lose the fat.
