The LFD had a small-to-moderate effect on decreasing total testosterone concentrations compared to the HFD. Although evidence points to a positive effect of dietary fat on circulating testosterone concentrations, it should not be dismissed that fat is not the optimal fuel source for athletes participating in strength/power sports [83,90,91,92 . ->

Given the importance of testosterone in overall health, it's crucial to understand how dietary choices, including fat consumption, can influence its production. What Are Healthy Fats? Healthy fats are unsaturated fats that provide essential nutrients, promote optimal brain function, and support heart health.
Highly Recommended: If you've been swayed by antiquated fitness industry myths like "consume six mini meals daily to turbocharge metabolism," "avoid carbs in the evening to avert weight gain," or the age-old advice of "consume protein every 3 hours to stave off muscle loss," it's time to reevaluate.
The research that is out there suggests that diets with less than 20% fats can inhibit testosterone production, particularly when compared to diets of around 40% fats [1]. There are a number of studies showing the importance of high fat diets when boosting testosterone levels.
However, Mikulski et al. showed that both low (35% protein, 64% fat, 1% CHO) and high (4% protein, 1% fat, 95% CHO) CHO meals decreased serum T levels in physically active subjects . Although CHOs seem to be positively correlated with circulating total T and SHBG levels in men [ 28 ], increased intake of refined CHO is associated with low serum .
PUFA decreased serum testosterone levels by 3. 2 nmol/L after 1 h compared to baseline ( p = 0. 023), with this suppression remaining significant up to 5 h postprandially (2. 1 nmol/L; p = 0. 012). The net overall testosterone levels were reduced by approximately 10 nmol/L × h by PUFA, MUFA and PUFA combined with CHO.
Cross-sectional studies show inconsistent associations between fat intake and testosterone in men. Methods Studies eligible for inclusion were intervention studies, with minimal confounding variables, comparing the effect of low-fat vs high-fat diets on men's sex hormones. 9 databases were searched from their inception to October 2020 .
These studies first put men on a high fat diet (40% fat), and then transferred them to a low fat diet (20% fat), and found their testosterone levels decreased by 10-15% on average. Particularly .
If you can minimize polyunsaturated fat consumption, you may go as low as 25% fat and keep your testosterone production churning. However, if you do eat some PUFAs, it's better to consume slightly more total calories from fat, more like 30-40%.
One team received a diet containing 40% fat and 45% carbs, whereas the other team ate a diet with 30% fat and 55% carbs (protein intake was identical). Both during and after the study, the researchers saw that the higher fat intake group had higher free testosterone levels, along with lower sex hormone binding globulin levels.

The World's Best Fats For Testosterone by Joseph LoGalbo on Aug 29, 2019 When it comes to eating fat, there are plenty of nay-sayers... Mostly ill-informed nay-sayers... But nay-sayers nonetheless... And sure, if you're a lady trying to slim down 3 weeks before summertime, I wouldn't recommend a beefy diet to you.
Firstly, diets < 3. 4 g/kg/day are not associated with a consistent decrease in testosterone. Secondly, the average protein intake is ∼1. 3 g/kg/day, conventional 'high-protein' diets are ∼1. 8-3 g/kg/day and the vast majority of athletes are < 3. 4 g/kg/day; meaning very few individuals will ever surpass 3. 4 g/kg/day.
Initial guidance strongly suggested limiting dietary fat to less than 30% of your daily calories. In 2005, that suggestion was revised to between 20-35% of your daily intake. Even this lower number is now under dispute by dietary researchers.
Standardised mean differences with 95% confidence intervals (CI) for outcomes were: total testosterone [-0. 38 (95% CI -0. 75 to -0. 01) P = 0. 04]; free testosterone [-0. 37 (95% CI -0. 63 to -0. 11) P = 0. 005]; urinary testosterone [-0. 38 (CI 95% -0. 66 to -0. 09) P = 0. 009]; and dihydrotestosterone [-0. 3 (CI 95% -0. 56 to -0. 03) P = 0. 03].
Serum testosterone and 4-androstenedione decreased from 22. 7 +/- 1. 1 nmol/l to 19. 3 +/- 1. 2 nmol/l, (SEM, P less than 0. 001) and from 4. 6 +/- 0. 2 nmol/l to 4. 3 +/- 0. 2 nmol/l (SEM, P less than 0. 01), respectively.
Testosterone promotes muscle growth. At the same time, it may suppress fat gain (2, 3, 4). As a result, some testosterone-deficient men tend to gain fat more easily than their healthy peers (5, 6). .
To do that, you need to understand five key points: How energy balance affects testosterone levels How micronutrient levels affect testosterone levels How dietary fat intake affects testosterone levels How carbohydrate intake affects testosterone levels How protein intake affects testosterone levels
How Much Do You Need? Current "guidelines" say that a healthy diet should consist of 25-35 percent fats, of which 10 percent or so should be saturated fat. And as we've seen, especially for men who are at risk of lower testosterone, making sure you get enough fats and especially saturated fats in your diet is essential.
Low-fat diets appear to decrease testosterone levels in men, but further randomised controlled trials are needed to confirm this effect. Men with European ancestry may experience a greater decrease in testosterone, in response to a low-fat diet. Androgen; Dietary fat; Low-fat diet; Meta-analysis; Sex hormone; Testosterone.
After 10 weeks of eating the high-fat diet, testosterone increased by 118 points, on average, while after the low-fat diet, levels declined by about 36 points. Similarly, a study of 3,000 men .
