Food & Lifestyle Recommendations
🍎 Food
Eat adequate dietary fat (30%+ of calories), lean protein, and zinc-rich foods (oysters, beef, pumpkin seeds)
Very low-fat diets reduce T by ~10-15%
🏃 Exercise
Lift heavy weights 3-4x/week with compound movements (squats, deadlifts, presses); add HIIT 1-2x/week
Resistance training and HIIT both raise testosterone acutely and chronically
😴 Sleep
Prioritize 7-9 hours of quality sleep; sleep restriction to 5hr drops T by 10-15%
Sleep is critical for testosterone production
🧘 Stress
Manage chronic stress; elevated cortisol directly suppresses testosterone
Cortisol-testosterone inverse relationship
💡 Other
Lose excess body fat if BMI >27; fat tissue aromatizes T to estrogen
Weight loss reliably raises T in overweight men
Evidence-Backed Supplements
When Low
-
Vitamin D deficiency correlates with low testosterone; supplementation raises T in deficient men
Vitamin D3 2000–5000 IU/day With fat-containing meal -
Zinc is a cofactor in testosterone synthesis; RCTs show benefit in deficient men
Zinc picolinate 15–30 mg/day Between meals -
Multiple RCTs show 10-20% increase in total T
KSM-66 root extract 300–600 mg/day With meals -
Magnesium reduces SHBG and increases free testosterone
Magnesium glycinate 300–400 mg/day Evening -
Some evidence for modest T increase
Standardized seed extract 500–600 mg/day Any -
Small studies show boron raises free T
Boron glycinate 3–10 mg/day Any
Questions to Ask Your Doctor
- Could this explain my fatigue, low libido, or mood changes? Low T symptoms often overlap with depression
- Should we check free testosterone, SHBG, and LH to identify the cause? Distinguishes primary vs secondary hypogonadism
- Would testosterone replacement therapy (TRT) be appropriate for me? TRT has benefits and risks; weigh carefully
