How can men support healthy testosterone levels?

Sleep, body weight, strength training and limiting alcohol are the evidence-based levers for testosterone. Here's what research shows and when to test.

Quick answer

How can men support healthy testosterone levels?

Men can support healthy testosterone with the fundamentals: enough sleep, a healthy body weight, regular strength training, limited alcohol and good stress management. In one study, a week of sleeping five hours a night lowered daytime testosterone by 10–15% in young men. Weight loss in men with obesity is also associated with higher testosterone.

At a glance

Key takeaways

  • One week of 5-hour nights lowered daytime testosterone by 10–15% in young men.
  • Weight loss in men with obesity is associated with higher testosterone.
  • Strength training, limiting alcohol and managing stress support healthy hormones.
  • Low testosterone should be diagnosed with repeated morning blood tests and symptoms.

Testosterone gradually declines with age, but lifestyle has a surprisingly large influence on where your levels sit.

1. Prioritize sleep

In a study published in JAMA, healthy young men who slept five hours a night for one week saw their daytime testosterone drop by about 10–15% — a change comparable to many years of aging. Consistent 7+ hour nights are one of the most powerful levers. See how much sleep adults need.

2. Maintain a healthy body weight

Excess body fat, especially around the abdomen, is associated with lower testosterone. A meta-analysis found that weight loss — through diet or surgery — was associated with increases in testosterone in men with obesity, with larger weight loss linked to larger increases.

3. Lift weights

Resistance training supports muscle mass and metabolic health, both tied to healthy hormone levels. Aim for two to three sessions a week — see strength training after 40.

4. Limit alcohol

Heavy drinking is associated with lower testosterone and poorer sleep.

5. Manage stress

Chronic stress and elevated cortisol can suppress the reproductive hormone axis. Regular recovery practices help.

6. Eat enough

Very low calorie intake and very low fat diets can lower testosterone. Aim for balanced meals with enough protein, healthy fats and micronutrients such as zinc and vitamin D.

When to get tested

The Endocrine Society guideline recommends diagnosing low testosterone only with consistent symptoms plus low morning testosterone on at least two separate tests. If you have symptoms, talk with a clinician rather than self-treating.

When should testosterone be tested?

Guidelines recommend morning testing, repeated on a separate day, when symptoms suggest low testosterone.
