March marks National Nutrition Month, a perfect time to think about how your diet impacts every aspect of your health — including hormone balance. Testosterone, often associated with energy and vitality, is directly influenced by what you eat. From the foods you choose to the patterns of your meals, your nutrition can either support or hinder your body’s ability to maintain healthy testosterone levels.
Recent studies have shed light on the connection between diet and testosterone, highlighting which foods can boost your levels and which may work against you. For men looking to optimize their health, understanding how nutrition and hormones intersect can unlock better energy, focus, and overall performance.
How Macronutrients Influence Testosterone
Testosterone production is influenced by several factors, including age, activity level, and body composition — but nutrition is one of the most modifiable. Here’s what we know:
Fats and Hormone Health
Healthy fats, particularly those high in cholesterol, serve as building blocks for testosterone. Research shows that men following low-fat diets tend to have lower testosterone levels than those consuming moderate amounts of healthy fats.
For most, aiming for at least 25% of daily calories from fats is ideal. Include sources like salmon, walnuts, and coconut oil to meet these goals.
One study published in Nutrients in 2021 found that men consuming a high-fat diet (75% of their dietary intake) experienced significant increases in testosterone levels during resistance training.
However, not all fats are created equal. Avoid trans fats and overly processed oils, which can have negative effects on both cardiovascular and hormonal health.
Protein for Muscle and Hormones
Protein is essential for muscle repair and growth, but excessive protein intake can sometimes interfere with testosterone. The same 2021 Nutrients study concludes that 1.6–2.2 grams of protein per kilogram of body weight daily is sufficient to maintain both muscle mass and hormonal balance.
Micronutrients and Testosterone
Zinc and Testosterone
Zinc is a key player in testosterone synthesis. It can be found in foods like oysters, beans, and pumpkin seeds.
The 2021 Nutrients study stated that there is a connection between zinc deficiency and low testosterone and referenced several studies that concluded that zinc supplementation can restore healthy testosterone levels.
Athletes, in particular, should prioritize zinc due to its depletion through sweat.
Magnesium and Testosterone
Magnesium not only supports muscle recovery but also helps maintain free testosterone levels by reducing oxidative stress. Free testosterone is the unbound form of testosterone that is actively ready for the body to use.
One study found that magnesium supplementation combined with endurance training increased both total and free testosterone concentrations in healthy men.
Interestingly, another study found that magnesium could reduce the binding of testosterone from SHBG (sex hormone binding globulin), further increasing free testosterone levels in the body.
Foods like almonds, spinach, and dark chocolate are excellent sources of magnesium.
Vitamin D and Testosterone
Vitamin D is often called the “sunshine vitamin,” but it may also play a role in supporting healthy testosterone production. Studies reveal that men with a vitamin D deficiency have significantly lower testosterone concentrations than men with healthy vitamin D levels.
Additionally, one study found that men who received daily vitamin D supplementation for 12 months experienced significant increases in total and free testosterone levels. Although the exact role that vitamin D plays in testosterone production is not widely understood, these findings emphasize the importance of healthy vitamin D intake.
The Impact of Dietary Patterns on Testosterone Production
Western Diets and Testosterone
A diet high in bread and pastries, dairy products, and desserts — the hallmark of a Western diet — has been linked to lower testosterone levels and poorer body composition, according to a 2018 study published in Nutrients. This dietary pattern is also associated with higher visceral fat, which can further suppress testosterone production.
Eating Out vs. Cooking at Home
The same 2018 Nutrients study showed that men who ate out frequently were more likely to have low testosterone compared to those who prepared meals at home. Homemade meals often included healthier options like dark green vegetables, which were linked to better testosterone levels.
Foods That Lower Testosterone
Certain foods, while common in the Western diet, can negatively impact testosterone:
- Refined Sugars and Carbohydrates: Diets high in refined sugar and carbohydrates are linked to lower testosterone concentrations.
- Processed Foods: Packaged snacks and fast food are associated with inflammation and hormonal imbalances.
- Dairy Products: Excessive dairy consumption can lead to significantly decreased testosterone levels in men.
- Alcohol: Consistent overindulgence in alcohol can increase the risk of testosterone deficiency compared to non-drinkers.
Minimizing these foods in your diet can help prevent hormonal disruptions and support optimal testosterone production.
Tips to Boost Testosterone Through Nutrition
To optimize testosterone levels, consider these actionable strategies:
- Incorporate Testosterone-friendly Foods: Make a habit of including spinach, salmon, eggs, and nuts in your meals.
- Plan for Balance: Ensure your plate includes a mix of healthy fats, lean protein, and complex carbohydrates.
- Avoid Testosterone-killing Foods: Limit processed foods, sugar, and alcohol.
- Don’t Skip Meals: Severe calorie restrictions can interfere with hormone production, so aim for balanced and consistent meals.
- Supplement When Necessary: If your diet lacks certain nutrients like vitamin D or zinc, discuss supplementation with your healthcare provider.

A Word on Weight Management and Testosterone
Diet and weight management go hand-in-hand when it comes to testosterone, and research has shown that obesity is associated with lower testosterone concentrations.
Excess weight, particularly around the midsection, can suppress hormone production. Even modest weight loss — around 15% of body weight — can significantly improve testosterone levels.
Balance Your Nutrition, Balance Your Testosterone
Nutrition is one of the most powerful tools for maintaining hormonal balance and overall well-being. By understanding the relationship between food and testosterone, you can make informed choices that not only support your hormone health but also improve your energy, focus, and vitality.
