Protein
How Much Protein Do You Actually Need?
The RDA of 0.8g/kg is the minimum to prevent deficiency — not the optimal amount for building or maintaining muscle. Current evidence supports 1.6–2.2g per kg of bodyweight for active individuals, with some research suggesting up to 3.1g/kg in caloric deficit to preserve lean mass.
Spread intake across 3–5 meals for maximal muscle protein synthesis. Aim for at least 0.4g/kg per meal as a floor. Leucine content matters — animal proteins and whey isolate rank highest for triggering MPS.

Carbohydrates
Carbs Are Not the Enemy
Carbohydrates are the primary fuel for high-intensity training. Glycogen depletion directly impairs performance and elevates cortisol — a catabolic hormone. For strength-focused individuals, carbohydrate intake should be periodized around training, not eliminated.
Focus on minimally processed sources: rice, potatoes, oats, fruit. Time the majority of carbs around training windows (pre and post-workout) for best body composition outcomes.

Fats
Dietary Fat & Hormonal Health
Dietary fat is essential for testosterone production. Studies show men on low-fat diets (<15% of calories from fat) exhibit significantly lower testosterone levels than those consuming adequate fat. Saturated and monounsaturated fats are most strongly correlated with T production.
Don't fear red meat, eggs, or olive oil. Fear seed oils, trans fats, and ultra-processed foods. Aim for 25–35% of total calories from fat, prioritizing quality sources.

Micronutrients
The Minerals Most Men Are Deficient In
Magnesium deficiency affects an estimated 50–60% of Americans. It's involved in over 300 enzymatic reactions, including testosterone synthesis, insulin sensitivity, and sleep quality. Zinc is equally critical — even marginal deficiency suppresses testosterone by up to 40%.
Top dietary sources: magnesium from dark leafy greens, nuts, seeds, dark chocolate. Zinc from red meat, shellfish (oysters are the highest), and pumpkin seeds. Supplement if dietary intake is consistently low.
