How Testosterone And Weight Are Connected

losing weight increases testosterone

There is a very connected and intertwined relationship between weight and testosterone. As you gain weight, your testosterone levels will naturally decrease.

By the same token, as you lose weight, your testosterone levels will naturally rise. To go along with this, as your testosterone levels rise, it will actually become easier to lose more weight because increased T levels also boost your body's metabolic rate and make it more efficient at burning fat, not to mention the increase in lean muscle mass.

Check out this study of a group of men that showed an increase in fat mass of 36% resulted in a decrease in testosterone from 600 ng/dL to 300 ng/dL. That 36% increase in fat mass cut their testosterone levels in half!

On the flipside, in another study, there were 900 overweight men that were put on a diet & exercise program for one year resulting in weight loss, which in turn, showed an overall increase of testosterone by 50%

What we know for a fact is that increased test hormone has a direct impact on fat and weight loss.

We also know that low T is definitely a contributing factor to obesity.

The other problem is the vicious cycle this creates.

Low T makes it easier to store and retain fat, which means you gain weight. Weight gain and obesity significantly impairs the production of testosterone, and now you have created the vicious cycle. To make matters worse, low T levels can also make your body resistant to insulin, and this means that when you eat food (especially carbs), instead of it getting used as fuel to burn, it gets stored as fat.

Low testosterone equals overweight

Simply stated, medical studies like this one have proven that the lower your T levels are the more likely you are to be overweight and the higher your test levels are, the more likely you are to have a lean healthy weight.

Dr. Julius Goepp

"Low testosterone promotes abdominal obesity in men. As men age, many become trapped in a vicious cycle that leads to life-threatening obesity"

Keep in mind that body fat contains aromatase, which is an enzyme that converts your test hormone into estrogen. Estrogen is the main sex hormone in women. Estrogen is bad for men because it triggers a man’s body to reduce its production of testosterone. The less testosterone you produce, the more belly fat you will accumulate.

The New England Research Institute reported that one of the most reliable predictors of low T is the based on the size of a man’s waistline. They even go as far to say that it’s more reliable or accurate than age or overall health.

Dr. Julius Goepp

"Published studies show that low testosterone and abdominal fat reinforce each other, trapping men in a spiral of weight gain and hormonal imbalance"

Belly fat directly affects androgen deficiency (Low T)

Researchers are also saying that an abundance of belly fat is the strongest predictor of a condition called androgen deficiency (AD). Symptoms of the androgen deficiency in males consist of loss of libido, impotence, infertility, shrinkage of the testicles, penis, and prostate, diminished masculinization (e.g., decreased facial and body hair growth), low muscle mass, anxiety, depression, fatigue, hot flashes, insomnia, headaches, and osteoporosis.

What medical studies are showing is that your testosterone actually has a way of inhibiting the creation of fat cells. Boosting your T will improve cholesterol and triglyceride levels, as well as lower your blood pressure. Not only that, but from a practical point of view, boosting your T levels will give you more energy and stamina as well, making your workouts even more beneficial!

Here’s the thing, you will naturally lose some testosterone as you age, but putting on weight will ACCELERATE THE DECLINING PROCESS, so why not do everything you can to naturally boost your T levels and put your body in the best shape it can be!

As men gain weight and raise their risk of obesity, testosterone levels dramatically decrease. It’s time to stop thinking of your stomach solely as a cosmetic problem but as a real organ that secretes hormones related to cardiac disease, obesity and low testosterone. The size of your abdomen is a key player in testosterone deficiency. The enzyme, aromatase, converts testosterone into estrogen in the stomach. Body fat rapidly increases this process
