What Men should Know About Testosterone and Weight Loss


Posted: July 10, 2017 at 11:46 am

Testosterone isnt just a question for the 40-and-up crowd. Far from it: if youre a human being (male or female) who wants to lose fat (or keep it lost), gain muscle (or keep it gained), or yes, enjoy sex, then testosterone is important for you to know about.

Its important to note, though, that testosterone does work differently in men and in women, so the advice for one sex doesnt necessarily apply to the other. For example, diabetes and obesity are associated with lower testosterone in men, but higher testosterone in women.

Because a full explanation of all things testosterone would probably fill a book, here well just be focusing on what men need to know about testosterone and weight loss. Why is testosterone important for men who want to lose weight, what are the effects of diet on testosterone, and how can Paleo help with hormone regulation during weight loss?

In healthy men, testosterone is a wonderful boon for fat loss (as opposed to just weight loss). As you could probably guess, this is particularly important for older men, but its still an issue for the 20somethings in the room. Testosterone helps build muscle, which ramps up your insulin sensitivity, maintains metabolic health, and delivers all kinds of other important benefits.

You can see just how important this is by looking at the worst-case scenario: low testosterone and obesity create a vicious cycle. Obesity impairs the production of testosterone, and lower testosterone makes it easier to store more fat. Low testosterone may also contribute to insulin resistance (the metabolic inability to handle carbs), ensuring that any carbs you eat will be shuttled off directly to fat tissue. Lower testosterone levels are also associated with other aspects of metabolic syndrome. Weight loss does improve testosterone levels, but only if you can break out of that vicious cycle in the first place.

Overall, its pretty clear that healthy testosterone levels are important for achieving and maintaining a healthy weight and more importantly, a healthy body fat percentage. You can be skinny but still metabolically unhealthy; the real goal isnt just a smaller number on the scale, but a better balance of muscle and fat (this is also what makes you look better naked).

With that said, its a cruel twist of fate that dieting in the traditional sense of the word is one of the worst things you can do for your testosterone levels.

The bad news for men who want to lose weight is that most diets dramatically lower testosterone levels (one reason why they tend to kill libidos so effectively). Its hard to avoid this entirely if you want to lose weight, but if you take a look at the reasons why dieting lowers testosterone its clear that there are at least a few ways to modify this.

Most diets involve eating a bunch of low-fat food and passing up the butter. Unfortunately for dieters, study after study has proven that eating a bunch of low-fat, high-fiber diet food is a fantastic way to tank testosterone levels, especially if the fat you do eat is polyunsaturated (PUFA).

The solution: for the love of your own abs (or for the hope of seeing them!), just say no to low-fat dieting! Instead, eat plenty of the good fats.

Theres a huge amount of back-and-forth about whether saturated or monounsaturated fat is better for raising testosterone, but if youre eating a solid Paleo diet, you should be getting enough of both to get the maximum benefit so it doesnt really matter.

Any kind of energy deficit (eating fewer calories than you take in) lowers testosterone levels, because the resulting weight loss steals some muscle mass along with the fat. This is inevitable; theres no way to lose only fat with absolutely 0 muscle loss. That means that any weight loss will reduce testosterone to at least a small degree, but theres no reason to make it any worse than it has to be!

The solution: preserve lean mass while losing weight. The more of your muscle mass you keep, the less testosterone youll lose. Heres how to do it:

Who likes dieting? Nobody. Dieting in the sense of starving yourself thin is stressful and painful. Those feelings of stress and general craziness are the results of a hormone called cortisol, which is the fight-or-flight master of the hormonal system. If you need a sudden burst of strength and speed (you get attacked, your kid falls into a river, youre trapped in a burning building), cortisol is great, but when its constantly elevated, cortisol becomes a problem. And unfortunately for the dieters of the world, producing more cortisol is a great way to lower testosterone levels.

The solution: keep cortisol levels low by generally reducing the stress in your life. This might sound a little crazy, but if a diet is driving you insane, find a different diet. Get 8-9 hours of sleep every night: sleep deprivation reduces testosterone levels, too. Dont run yourself into the ground at the gym, and eat enough for the workouts that you do. Its not complicated; it just takes a little common sense.

As discussed in the intro, women work a little differently when it comes to testosterone thats a topic for another day. But for men, at least, it should be pretty clear that the conventional model of dieting isnt doing anyones testosterone levels any favors. Its much more pleasant (and easier!) to lose weight in a way that preserves testosterone as much as possible.

If youre interested in making that happen, Paleo gives you a much better shot at it than just restricting calories and making better friends with your treadmill. Eat enough protein and enough healthy fat, lift some heavy weights once in a while, and dont do things that make you crazy, stressed out, or miserable.It may also help to eat some oysters every now and again, or otherwise make sure youre getting enough zinc.

You might not see the number on the scale go down quite as fast this way (because youre preserving your muscle mass, which is all the same weight to the scale), but the weight loss will be easier to maintain and a lot less painful and itll leave your sex drive, mood, and overall health intact.
