New To Keto But Want To Grow Your Knowledge?
More specifically, you want help with How Testosterone Affects Fat Loss: Real Science of Low-T | Thomas DeLauer?
hey it’s Thomas de Lauer and today I want to dive a little bit deeper into testosterone and the actual legitimate scientific correlation between testosterone and fat accumulation but before I do that let me give you a broad overview of testosterone and how it affects us okay as we get older testosterone levels start to decrease now additionally we have an increase in what’s called the shbg the sex hormone binding globulin I’ve talked about it in other videos basically what happens is that sex hormone binding globulin holds on to a lot of our testosterone that is available and locks it up so that means we’re left with very very minimal amounts of testosterone that we can actually utilize as we grow older so why does this correlate with fat accumulation so let’s go ahead and dive into that the first one that we have to look at is the correlation between testosterone levels and energy it’s kind of an obvious one okay when your energy levels are low you’re not as active which means you’re probably not going to burn as much fat but there’s more to it than just what’s on the surface you see it comes down to that mitochondrial function you hear me talk about in a lot of my videos always talking about how the mitochondria is that energy powerhouse it’s so critical for us to take care of it I think a lot of us neglect the mitochondria in general you see what happens is that low testosterone function ends up making it so that we’re not able to metabolize our proteins or fats and our carbs as efficiently it slows down that entire process which can essentially end up leading to some fat accumulation some of the studies that I’ve looked at found that lower levels of testosterone dramatically affected the amount of lipid oxidation what that means is it’s dramatically decreasing the mitochondrial function to be able to use fat as a source of fuel it means that now the mitochondria has to focus more so on utilizing glucose for fuel which may not be the healthiest route especially as we get older and for what it’s worth this isn’t bro science there is a lot of science out there that backs this up in fact it’s shown that 40% of obese men have low levels of testosterone and over 50% of obese diabetic men have extremely low levels of testosterone now that diabetic link is extremely interesting as we start looking at insulin resistance and I’m going to get to that in just a second before I talk about the insulin resistance in general let’s talk about how the body normally utilizes glucose you see when we are functioning normally our bodies are going to utilize glucose for energy when we start depriving ourselves of glucose or when we start exercising intensely those glucose levels drop and our bodies start utilizing fat for fuel a little bit more well if lipid oxidation is not functioning properly within the body due to low testosterone your body is going to always be looking for glucose to use and it’s just going to let those lipids circulate and ultimately store one of the major reasons why we have heavy fat accumulation when we have low levels of testosterone okay but now since we have so much levels of glucose flowing around as well we have to look at insulin resistance you see when your body is not able to utilize sugars right not able to utilize carbohydrates it’s generally because you have what’s called insulin resistance when you consume a carbohydrate your body secretes insulin that insulin allows the carbohydrate to go into the proper storage goes into the muscle in the form of glycogen but if you’re having an issue with insulin resistance for example a type 2 diabetic would be insulin resistant it’s going to make it so those carbohydrates are just floating around through the bloodstream well this can ultimately cause them to get stored as fat which leads us into an entirely different section so now we have to talk about hormones and how does the link between fat and hormones work well it’s simple when our testosterone levels are lower and our bodies are running predominantly on glucose they’re not utilizing the fat so of course we’re storing the fat but that fat actually causes an enzyme attic response that causes that testosterone to convert into estrogen see what happens is fat contains something called aroma taste so if you have relatively low levels of testosterone your fat stores are going to convert that testosterone via aroma taste into something called estradiol which is also known as estrogen estrogen gives you the non male characteristics they can cause that gynecomastia they can cause that fatigue they can cause the moodiness that’s where a lot of these effects take place with low testosterone and you can see how this can steamroll so low testosterone levels means more body fat more body fat means more conversion of testosterone into estrogen that means lower levels of testosterone which means more fat accumulation you can see it just continues on down the line now to add insult to injury we look at insulin resistance and we look at the overall link between fat accumulation and fat gain and insulin resistance the more fat that you have the more insulin resistant you are so therefore it’s even easier to store that fat one more thing we have to look at is the c-reactive protein levels so when we have high levels of fat our c-reactive protein and inflammatory markers are elevated which links to even lower testosterone levels so again we look at this and we say which came first the chicken or the egg did obese people develop low testosterone or did low testosterone linked to fat accumulation well it could go either way but one thing is for certain if we can take care of our bodies and make sure that we are utilizing fats for fuel properly and making sure that we’re taking control of our insulin response we can mitigate some of these issues that can occur so what I propose to you and now again I’m not a doctor so I can’t write you a specific diet plan that says this is what you need to do but I can definitely hypothesize it if we start controlling our carbohydrates and we can condition our body to run on fats for fuel a little bit more possibly even a ketogenic style diet then we can potentially force the body to start utilizing fats and not have that excess glucose that’s causing that insulin resistance because at the end of the day if you’re on a ketogenic diet that insulin resistance isn’t going to be as big of a deal the reason that I suggest this is because I talk to a lot of guys I talk to a lot of stressed-out guys that are middle-aged that are working hard and they’re really frustrated because their sex drives are down their libidos not good their motivations down but they don’t want to necessarily go on testosterone replacement therapy and I don’t blame them that’s a big commitment so the first step is to take control nutritionally understanding how to Stas ruin links with fat accumulation and understanding that cycle that vicious circle that occurs so you can break the cycle and at least stop your testosterone levels from declining anymore as always keep it locked in here in my videos if you have any comments of these suggestions on videos be sure to put them in the comment section below I’ll get my research team on it will produce an awesome video see you in the next video

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
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.
