How Testosterone Affects Fat Loss: Real Science of Low-T | Thomas DeLauer: I’m sick of the lack of legitimacy behind testosterone, so let’s clear some of this up. I work with a lot of men that are battling Low-T by helping them with their lifestyle at http://www.ThomasDeLauer.com

As men age, their testosterone levels decline. This is exacerbated by an increase in SHBG (sex-hormone binding globulin), which binds to testosterone and thus reduces the amount of free testosterone in the body. Low testosterone levels have been linked to obesity and many other health problems, including fatigue, memory problems and reduced muscle and bone mass. So what is the impact of testosterone on body fat?
Testosterone and energy – low levels of testosterone are linked with low energy levels. Regaining regular testosterone levels can increase energy and lead to weight loss. Studies have found that testosterone supplementation reduces total body fat percentages. Obesity is often correlated with low testosterone levels in men. Just as testosterone therapy is associated with decreased obesity, losing weight is associated with increased testosterone levels.
An article published in 2014 in the journal of Current Opinion in Endocrinology, Diabetes and Obesity looked at the existing data regarding testosterone therapy in overweight and obese men with testosterone deficiency (hypogonadism).
-Many weight loss supplements have dangerous side effects or are ineffective
-Looked at weight loss, BMI, waist circumference and body composition
-Evaluated long-term testosterone therapy
-About 40% of obese nondiabetic men and 50% of obese diabetic men over 45 have low levels of free testosterone
-Many studies have found that testosterone therapy in obese men is correlated with increased lean body mass, weight loss, decreased BMI and reduced waist circumference.
-Weight loss is significant and sustained with long-term testosterone therapy

Testosterone plays a part in protein, fat and carbohydrate metabolism.
-Testosterone is involved with mitochondrial function and thus energy production and utilization
-This interference with energy production is likely why those with low testosterone levels experience a lack of energy
-Testosterone therapy has been found to increase lipid oxidation and normalize glucose use in the body. It was found to increase energy and motivation.

Weight gain is associated with an 88% increase in body fat and a 12% increase in lean body mass (LBM) and weight loss with a 72% decrease in body fat and a 28% decrease in LBM.
-With testosterone therapy LBM has been shown to increase.
-Increased LBM means increased energy expenditure at rest
-Testosterone therapy is also associated with improved cardiometabolic function

Testosterone deficiency is linked with a decrease in energy metabolism from fat and an increase in energy metabolism from glucose.
-Testosterone therapy has been shown to increase lipid metabolism

Safety? Safety is the main concern with testosterone replacement therapy. Possible risks discussed in literature include:
-Increased risk of prostate and breast cancer
-Liver toxicity and tumors
-Sleep apnea exacerbation
-Testicular infertility and atrophy

It is necessary to talk with your doctor before starting testosterone therapy.
Summary: If you are a male struggling to lose weight, testosterone therapy is a promising treatment to help with not only weight loss but body composition, energy levels and overall health.

  1. this guy is on at LEAST 400 mg of test (roids) per week. you can tell by his small frame and neck that those arms are not possible

  2. hey ,if anyone else wants to uncover
    best testosterone supplements
    try Mackorny Increase Testosterone Blueprint (do a search on google ) ? Ive heard some awesome things about it and my friend got amazing success with it.

  3. Thank you for explaining this. I am actually going to see a Doctor for my Low T. I used to be very active but I got lazy after an injury requiring arm surgery and it actually scared me a bit to use my arm again. I gain a lot of weight and I need a good plan to get me back on the right path. I am 52 and feel older. My Dad is 78 and walks at least 3 miles a day and still officiates high school football in Pennsylvania. I want to feel whole again for my wife and myself.

  4. Look at excelmales videos on Estradiol. This video is incorrect on many fronts. Gynocomastia doesn't happen because of Estradiol. There's a lot of new research that disproves these points.

  5. You don't have to be overweight to have Low T. But I'm not surprised about the correlation between low T and obesity.

    I'm 40, 5'9" and 190lbs. I look kind of like a body builder but I train boxing and Muay Thai 4x a week and strength train 1 or 2 times a week. I carry a lot of muscle but my body fat has steadily increased over the last couple years from 12% to a high of 17%. I can train high intensity boxing and muay thai for a few hours. I'm in really good shape yet carry a little bit of extra fat. After testing for everything else, the only thing left was to test my T levels. I came back at a very low 237. This was two weeks ago. I'm now on a TRT/HCG program. I haven't felt any different yet but am looking forward to it.

    Most of my side effects from Low T are emotional. I'm highly irritable, tired, moody, forgetful, etc. Physically I have had some side effects but without my training program, the lingering low level anxiety of Low T will take over. So I force my self to workout everyday.

    Get to the gym guys. That to me is step one. Don't like 24hr Fitness? Sign up for group boxing classes.

  6. If you're wondering if being fat causes low T or does low T make you fat, I can share my experience to shed some light on the subject. I was very skinny, about 155-160lbs, never weighed more than that in my entire life. Lost both testicles from cancer and POOF i puffed up to 200lbs in a matter of a few months. So for me having low testosterone absolutely made me get fat. And pear-shaped womanly estrogen fat. Not a good look.

  7. Thanks for the video. Testosterone level in females is and should be low. How does it work for them. Could you please comment on this?

  8. Great video, very informative. I have a question

    I am overweight and have about 30 lbs of fat to lose, I have low testosterone and slightly high estradiol levels, I understand the correlation between fat consumption and increased testosterone, but I have been diagnosed with gallstones and a fatty liver so have to be careful of how much fat I consume.

    I want to suggest I do to increase testosterone, and lower estradiol?
