At the age of 20th the woman   complaining about her difficulty in losing weight. After taking a medical history , it was very difficult to tell what the basis of her problem was. She was working out daily, with a balance of aerobic exercise and weight training under the guidance of a qualified personal trainer. Her diet was a basic low carbohydrate/ high protein diet.

Even more perplexing, she had been taking a caffeine/ephedrine thermogenic stack and had previously experimented with some diet drugs as well. Something was obviously wrong. I did blood tests to check all of her hormone levels. When the results came back, all of her hormones were in the normal range except for, you guessed it, testosterone! She had very low  testosterone levels. It was equal to that seen in a postmenopausal women. This was an obvious source of her fat loss problem .

It is known that many women begin to gain fat rapidly about ten to fifteen years before the menopause and also after. The connection between low to absent testosterone production and the deterioration of a healthy body composition is rarely made. Most women are often only given estrogen and progesterone as hormone replacement therapy, but not testosterone. I have found in my medical practice that giving women estrogen and progesterone and not testosterone hormone makes it almost impossible for them to lose weight/fat.

Many doctors point to a recent study showing that when postmenopausal women given estrogen actually gained less weight than those not given estrogen (Espeland, et al, 1997). In this study 875 women were either put on .625 mg of oral estrogen a day or a placebo for three years. So does this mean that estrogen is actually a good fat-loss agent?

Hardly! In this study, in spite of the publicity it was given, the authors note that when you control for lifestyle factors such as physical activity the effects of estrogen replacement therapy were insignificant.
