I been in the gym biz since 1988 and have competed in bodybuilding since 1983 and can tell you your diet is HUGE, figure out if your more carb sensitive or fat sensitive and act accordingly. As a rule as we age we become more vernerable to carbs, which I personally crave but I always burn them off via cardio or w free weights. Calories are defined as a unit of energy so use them as such, low cal diets equate low energy which negatively effect yr training
But good work guys who have worked out, Kudos to all you, keep it up!
