Ectomorph I do want to say that no one is immune to gaining weight as we get older. My diet calendar does not reflect my gaining weight nor does it reflect how many calories I really eat per day, I eat more. I look at my brothers with the same body type (small ankles and wrists) and one of them is very muscular but not bulky in any way. A type of body that would not get bulky easily, would do better eating more carbs, carbs being within reason and has more energy for longer distances.
