Lose Weight the Right Way
A lot of guys on a new weight loss program don't realize that weight loss can be
very hard on the body and mind if not done correctly. Furthermore, some
weight loss programs can actually sabotage the very goals of losing weight that
you're trying to achieve.
This is the reason I put together a list of three items that show the "right
way" to lose weight according to the latest research:
Do you know the foods and drinks that increase erection-boosting
Nitric Oxide? Check out the
Peak Erectile Strength Diet where I show
you how to dramatically and naturally improve your erectile strength.
1) Maintain Adequate Calorie Levels.
Be cautious about cutting calories too fast and too deep: it can
whack
your testosterone. The body goes into "starvation mode" and that
includes starving your system of precious hormones such as testosterone. For
example, after just a few days of fasting, you
testosterone levels can lower by a third or more. [2] Not only
does dropping calories too fast whack your total testosterone, but it also
raises SHBG. [5] SHBG is Serum Hormone-Binding Globulin, a protein that binds to
the lion's share of your testosterone. The little bit left over, around 2% of
the total, is what your body can actually use since it is bioavailable.
So, if you increase SHBG through dieting - and incresing SHBG is a problem for
aging males anyway - more testosterone is bound leaving you with less free
testosterone. So how many
calories should you cut? Well, one study found that subjects that lowered
caloric intake by 15% did not experience a loss in total testosterone. [4] Again,
it is
better to lose weight gradually, relying on exercise and a balanced diet than
the typical crash and burn programs that so many people engage in. And, if
you will follow the Low Fat (or Ornish) Diet, you can lose weight and barely cut
back on calories at all, thus avoiding a nasty fall in total and free
testosterone.
2) Avoid Low Carb (Atkins) Diets. If you want to put on muscle,
carbohydrates have been found to be just as critical to muscle growth and
recovery as protein. [6] Those with adequate carbohydrates had much
improved protein synthesis over low carb study participants and protein
synthesis is critical for rebuilding muscle tissue. (See my page on
other Dangers of Low Carb or Atkins Diet for more
information.)
When does low testosterone
cause erectile dysfunction or harden your arteries? 300 ng/dl? 400?

Testosterone By The Numbers.
3) Consume High Protein Levels. When dieting, you may want to consider
very high protein levels in order to keep your muscle mass. Of course, one
of the curses of dropping pounds is that you drop muscle along with fat.
(This can be exacerbated by #1 as well.) One 2010 study found that
consuming about 35% of calories, or 2.3 g/kg of body weight, signficantly
protected male dieters from muscle loss when compared to participants consuming
the more traditional 1.0 g/kg of protein (15% of calories). [7] The
latter, 1.0 g/kg, is the minimum that you'll see most bodybuilding and weight
training sites recommend for muscle building. Consuming 35% of calories
from protein is a very high level indeed, but maintaining muscle is crucial,
since if you lose muscle it is much harder to maintain your weight post-diet.
Why? Muscle is a much more efficient fat-burner.
