Menopause
and Obesity
After menopause, many women notice that their
muscle-to-fat ratio tilts in favor of the latter and the battle of
the bulge is increasingly difficult. All the hormones, especially
estradiol and testosterone, can help tip the scale back in the right
direction.
Estradiol, increases fat breakdown from body fat stores so that it
can be used as fuel and increases basal metabolic rate, while
testosterone has been shown to maintain muscle tone, volume, and
strength, increase metabolism, and decrease body fat.
In a 2000 study, featured in Menopause, estrogen supplementation had
effects on body fat distribution in postmenopausal women that was
associated with improved lipid parameters.
The Journal of Clinical Endocrinology
and Metabolism reported that obese women given low doses of
testosterone lost more body fat and subcutaneous abdominal
fat, and gained more muscle mass than women who were placed on a
placebo.
In a 2006 study, researchers writing
in the medical journal Diabetes, Obesity & Metabolism found
"HRT reduces abdominal obesity, insulin resistance, new-onset
diabetes, lipids, blood pressure, adhesion molecules and
procoagulant factors in women without diabetes and reduced insulin
resistance and fasting glucose in women with diabetes."
Women are not alone in the hormonal decline department. Men also
experience a falling off of hormone levels. In my practice, I have
found that most men over forty suffer from low levels of
testosterone, a condition called andropause, or male menopause.
Testosterone decline may be linked to many age-related symptoms like
muscle weakness, bone loss, memory complications, weight gain and
heart disease. As far as quality of life is concerned, in the
absence of normal-to-high levels of testosterone, men suffer from
mood swings, fatigue, and libido dysfunction
Not everyone will benefit from hormone supplementation. The goals,
realities, and risks of hormone supplementation should be discussed,
at length, with your physician prior to onset of treatment.

Insulin Resistance, Weight Gain Lead to Early Aging
When we eat, our bodies release
insulin into our blood stream so that we can process glucose
(sugars) from our foods to make energy, especially in our
muscles. Glucose belongs in our cells and
not in our blood. When it remains in our blood we produce more
insulin. Increased insulin, according to many researchers, is
the number one factor for accelerated aging. |

UCSD Study Sheds New Light on Insulin’s Role in
Blocking Fat Breakdown in Patients with Type II Diabetes
"Chronically high levels of insulin, as is found
in many people with obesity and Type II diabetes, may block
specific hormones that trigger energy release into the body,
according to researchers at the University of California, San
Diego (UCSD) School of Medicine. Their findings, which may point
to new approaches to developing improved treatment options for
the disease..."
