There is a way to look and feel great at any age.
It certainly gets tougher to look and feel great when you reach your middle age.
Your metabolic rate slows down and energy production drops.
That speeds up fat storing.
No matter what diet you start, 95% of all diets are doomed to fail.
Haven't you seen "successful" dieters that look awful after they lose weight?
Dieters that have lost weight shrank in their size but haven't improved
their body composition.
Body composition is the ratio between "body fat" and "lean body mass".
Body fat is obviously the amount of total fat in your body.
Lean body mass is your body weight without the body fat.
This is the only way you should measure your fitness and shape.
Your muscles are the main variable in your lean body mass.
Therefore lean body mass is a good estimate for your lean muscle mass.
That's the all theory.
On a typical weight-loss diet, you will lose about 65% fat and 35% lean mass.
When you go off the diet, which most people do because it's so unsatisfying,
you gain the weight back.
You don't reverse to your original body composition.
You gain back 80% fat but and only 20% lean mass.
Anti-aging literally offsets the aging process. Muscle gain and fat loss.
That's exactly the opposite of aging (muscle loss and fat gain).
