I don't have a diet plan but I'm of the opinion that one half of good fitness and health is exercise and the other half is portion control. We are not as active in later years as we were in earlier years so we do not need as many calories. Evidently, many are surprised by this fact and continue to eat in the same way as when 17 years old. Eating healthy and nutritious meals in proper amounts is mostly a matter of habit but making good habits takes effort. O.P. you have the exercise part down.
