Does the HCG Fast Diet Increase Testosterone Naturally
Yes, the HCG Fast Diet Increases Testosterone Naturally.
The HCG Fast Diet Increases Testosterone Naturally in men stimulating multiple testosterone axis pathways.
The HCG Diet Injections Mimic an Increase in Luteinizing Hormone
The first action of the HCG Fast Diet is due to its natural ability to stimulate endogenous testosterone production in the male testes. It does this by mimicking the physiological effects of luteinizing hormone (LH). LH signals to the male testes to produce more testosterone naturally. When men follow our HCG Fast Dietprogram, we generally expect to see a rise in testosterone levels by as much as 287%, due in part by the stimulating action of LH by HCG injections combined with a specific intermittent fasting protocol.
The normal male testicular function is achieved by gonadotropins which are released from the pituitary. The gonadotropins are Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH). LH stimulates the production of Leydig cells. Leydig cells produce testosterone within the testis in men. These hormones are regulated and balanced in healthy individuals through a NEGATIVE FEEDBACK LOOP of testosterone at the hypothalamus and pituitary glands. As testosterone increases, this negative feedback loop signals the hypothalamus and pituitary to produce less LH and FSH.
Note: Men with excess abdominal adipose tissue, a hip to waist ratio or body mass index which is too high, may negatively influence the delicate balance of the hypothalamus, pituitary, and the precursor of LH, and may produce lower than normal testosterone levels.
When men between the ages of 18 and 41 and a mean age of 24, were given HCG injections over a three week period, testosterone increased most in the men that received 250 IU every other day. As part of the HCG Fast Diet, we typically prescribe 250 IU daily injections for the 23-day diet program. In some instances, injections won’t last the full 23-days depending on slippage (wasted or spillage due to the mixing or injection process), but this isn’t critical, because studies have shown that occasionally missing a dose or two (even every other day) can result in an improved outcome in testosterone increase.

Increasing testosterone levels with HCG injections on the HCG Fast Diet is just one method of how testosterone levels are increased on the program. The other influence to stimulating more testosterone production in men on the HCG Fast Diet is by intermittent fasting. Intermittent fasting, when introduced on the HCG Fast Diet, accelerates weight-loss as well as increasing testosterone production.
Short-term Fasting was Shown to Increases Testosterone Production in Obese Men by as much as 180%.
Short-term fasting increased the GnRH-elicited LH response by 67% in the non-obese group (LH incremental areas 2147 +/- 304 vs 3581 +/- 256, p less than 0.01), and the corresponding testosterone response by 180% (testosterone incremental areas 111 +/- 61 vs 311 +/- 49 micrograms.l-1.min-1, p less than 0.01). These results imply that food deprivation affects the pituitary-testicular axis differently in obese and non-obese men (Rojdmark S., Asplund A., Rossner S. 1989) <Click here>.
Note that in men with a body mass index greater than 39, did not see the gains in testosterone. Luteinizing Hormone increased 26%, whereas in men with a more normal body mass index LH increased by 67%. This shows how obesity negatively influences the pituitary-testicular axis in men, and why it is so important to consider a program like the HCG Fast Diet to decrease weight in order to improve metabolic health and optimize natural testosterone production before undergoing a full low-t program.
In addition to an increase in testosterone on the HCG Fast Diet, the HCG Fast Diet and its protocols also positively influence the production of endogenous human growth hormone production. This is due as a result of the fasting protocols, but there is also some evidence that the increase in the pituitary-testicular axis can help this increase as well.
Although it is not the intent of this article to address all the physiological events which naturally occur when men are placed on the HCG Fast Diet, just the improvement in testosterone alone is an important and desired benefit which most men will experience when the protocols are followed correctly.
