Informed consent was obtained from all individual participants included in the study. The procedures used in this study adhere to the tenets of the Declaration of Helsinki. We found these inverse associations were nonlinear. The weighted methods were utilized in all analyses. Linear regression models assessed the associations between VAT area and TT. TT in serum was assessed utilizing the isotope dilution liquid chromatography-tandem mass spectrometry technique.
Testosterone is an agonist of the androgen receptor (AR) and a pro-hormone capable of being converted to the more potent androgen, dihydrotestosterone (DHT), or estradiol by 5a-reductase and aromatase, respectively. Obesogenic adipogenesis is also elevated in mice where androgen receptor activity is inhibited. We thank the funding support for co-author FZ’s study. We invite you to schedule a free, initial consult with our medical team to answer your questions and see if you may be eligible for testosterone replacement therapy.
By taking control of these interconnected factors, you can pave the way for a more active, healthier life. By adopting a lifestyle involving regular exercise, a nourishing diet, stress management, and quality sleep, you can significantly improve your health. Grasping this relationship empowers individuals to make informed choices that support both fat reduction and hormone balance. This condition can trigger numerous hormonal imbalances, making it crucial to address this type of fat.
That means that as estrogen levels rise, the body produces less testosterone. There is also some evidence that cold exposure may increase brown fat in the body, which may help us to burn more calories without changing our food intake or activity.One study asked healthy mean to undergo a month of exposure to mild cold for at least 10 hours each night. More fat in the limbs, hips and breast area are all signs of high oestrogen levels in men. Yes, body fat can affect testosterone both negatively and positively. But it is worth bearing in mind that this will not give you abs in and of themselves; dieting to a low level of body fat is nearly always necessary.If your stomach often feels doughy or solid despite even though your body fat level is low, it could be a sign of physical stress. In nearly all cases, lowering your body fat percentage requires weight loss.The great news is that the science behind weight loss is very simple; you need to create a calorie deficit or a negative energy balance. Higher levels of muscle mass mean you can eat higher calories at rest without gaining weight.
Another study, by Hofstra et al, also reached similar conclusions, and reported that about 35% of men with obesity had testosterone level under 300 ng/dl, diagnosed as testosterone deficiency . This study was conducted to explore the association between visceral adiposity index (VAI) and testosterone level. Research has shown that testosterone levels play a key role in changing the distribution of fat from subcutaneous to visceral as we age. Treating castrated mice with either testosterone or DHT completely rescued this effect (Figure 4B,C), which was surprising due to the inability of DHT to reduce total fat mass gain on an HFD (Figure 3B). Notably, testosterone blocks the expansion of both visceral and subcutaneous fat (Figure 3E,G), and DHT specifically impedes subcutaneous fat growth (Figure 3E,G) without significantly impacting total fat mass (Figure 3B).
Understanding how excess visceral fat impacts testosterone levels is vital for improved health and well-being. This includes not only muscle but everything in your body that is not fat, such as your organs, skin, bone, fluid levels, food weight, and stored glycogen.However, when we are talking about what is ‘optimally’ healthy, there is an important difference between BMI and body fat percentage.BMI does not account for body composition at all. However, due to the influence of testosterone, men are far more likely to store fat around the midsection, around the organs in particular.If you are overweight yet your stomach is hard or looks pregnant, it’s a sign that you have high levels of visceral fat. If you weight train or exercise regularly, you will look okay in clothes, but probably wouldn’t make a magazine cover with your shirt off.Your health would be good under most circumstances, and you should have low levels of visceral fat, providing your diet is in check. As a result, it is confusing for andrologists to use these simple indicators to explore the associations between obesity and testosterone deficiency, and it is better to accurately assess visceral adiposity because visceral fat is more metabolically deleterious than subcutaneous fat 40,41.
While weight loss is the primary and most effective treatment for high estrogen levels due to obesity, it may not always completely resolve the issue. As men age, their testosterone levels naturally decline, while their estrogen levels tend to remain relatively stable. Table 3 displays the subgroup analysis of the association between total testosterone level and VAI index. Men with a higher VAI index have a higher risk of declined testosterone level, or even testosterone deficiency, especially in aged men, or men without diabetes.
