Regarding number 3, perhaps you would want to read up about yo-yo
dieting and its harmful effects. I see it happening to my gf's
female fren right now, and it was something I had already predicted
when she started dieting last time.
Regarding number 4, research has shown that osteoporosis and muscle
loss occur as soon as we are reach the age of 25 years old.
However, exercises, especially weight training, will reduce, or
even reverse, such effects. Without it.... you can imagine....
Think of the sedentary old folks that you see around...
Now, before one comment that someone else has better genes, think
of this question: are you at you genetic potential yet? If not,
reach there before complaining about genetic quality.
