How to Increase Testosterone Naturally: Sleep, Training, Food and What Actually Works

Educational content, not medical advice. This article is general information from a fitness coach. It’s not a diagnosis or treatment. If you have a health concern, see a doctor. See “When to see a doctor” below.

Testosterone helps you build muscle, keep your energy and sex drive up, and stay lean. Levels drift down slowly with age, by about 1% a year from around age 30 to 40 (Baltimore Longitudinal Study of Aging), but the bigger drops usually come from things you can change: short sleep, extra belly fat, no strength training, heavy drinking and chronic stress. This guide covers what actually works to increase testosterone naturally, a simple 4-day training plan, the foods and nutrients that matter, and when it’s time to get a blood test instead.

What lowers testosterone in men?

Before adding anything, it helps to know what drags testosterone down. The common, fixable causes are:

• Short or poor sleep. Most testosterone is released during sleep, so cutting it short has a quick effect.
• Excess body fat, especially around the waist. Fat tissue converts testosterone to estrogen and is linked to lower levels.
• Inactivity and loss of muscle.
• Heavy drinking. The NHS lists reduced fertility and sexual problems among the risks of drinking too much. See also how alcohol affects muscle growth.
• Chronic stress and very high training loads without enough food or rest.
• Very low-fat or very low-calorie diets kept up for a long time.

Medical causes, such as type 2 diabetes, some medicines, pituitary problems or damage to the testes, need a doctor. That’s covered at the end.

1. Fix your sleep

In a small but well-known University of Chicago study, young healthy men who slept 5 hours a night for one week had 10 to 15% lower daytime testosterone, about the same as 10 to 15 years of ageing. Sleep is the cheapest testosterone “supplement” there is.

• Aim for 7 to 9 hours in bed, at roughly the same times every day, weekends included.
• Keep the bedroom dark, cool and quiet. No phone in bed.
• Cut caffeine after early afternoon and keep alcohol light.
• If you snore loudly or wake up exhausted, ask your doctor about sleep apnea. It’s common in heavier men and linked to low testosterone.

A few minutes of slow breathing before bed helps many men switch off. The drills in our breathing techniques guide work well for that too.

2. Lose excess body fat

If you’re carrying extra weight, this is where the biggest gains are. A meta-analysis of 24 studies found that weight loss, by diet or by surgery, was linked to a significant rise in testosterone, and the more weight men lost, the bigger the rise. You don’t need a crash diet. A steady loss of about 0.5 to 1% of body weight a week, while keeping protein high and lifting weights, protects muscle and hormones.

Simple meal structure helps. The 30-30-30 diet plan and our high-protein recipes for belly fat are good places to start.

3. Lift weights 2 to 4 times a week

Resistance training causes a short-term rise in testosterone, and the effect is biggest with heavy, multi-joint exercises that use a lot of muscle, moderate to heavy loads and short rests. That temporary spike isn’t the main point, though. The long-term benefit comes from building muscle and losing fat, which supports healthier levels week after week.

What matters most:

• Compound lifts first: squats, deadlifts or hip hinges, presses, rows and pull-ups.
• Moderate to heavy loads: mostly 5 to 10 reps, finishing each set with 1 to 3 reps left in the tank.
• Progressive overload: add a little weight or a rep each week.
• Recovery: 48 hours before training the same muscles hard again.

A simple 4-day testosterone-friendly plan

Day	Session	Main exercises
Monday	Lower body strength	Squat 4×6, Romanian deadlift 3×8, walking lunges 3×10 per leg, plank 3×30 s
Tuesday	Upper body strength	Bench press 4×6, bent-over row 4×8, overhead press 3×8, pull-ups 3× max
Wednesday	Walk or rest	30 to 45 minutes brisk walking, or mobility and stretching
Thursday	Full body + short intervals	Deadlift 3×5, push-ups 3×12, kettlebell swings 3×15, then 6 × 30 s hard bike or hill sprints with 90 s easy
Friday	Upper body volume	Incline dumbbell press 3×10, chin-ups or lat pulldown 3×10, dumbbell row 3×10, curls and triceps 2×12
Weekend	Active rest	Long walk, sport or light cycling

New to lifting or training at home? Start with the equipment-free workout routine for 4 weeks, then move to weights. If you prefer fewer, harder sessions, Mike Mentzer’s Heavy Duty workout is another option. Whatever you choose, the plan you stick to beats the perfect plan you quit, as we cover in how to stay consistent with your workouts.

4. Use cardio, but don’t overdo it

Moderate cardio is good for your heart, your waistline and your erections, so keep it in. Aim for the CDC’s 150 minutes of moderate activity a week in total, for example brisk walks on rest days plus one short interval session. Problems tend to start only with very high endurance volume combined with too little food and sleep. Signs you’re overdoing it: constant tiredness, poor sleep, low sex drive and stalled progress. If that’s you, take a lighter week and eat more.

5. Eat for testosterone

There’s no magic testosterone food, but your overall diet clearly matters. A 2021 meta-analysis found that men on low-fat diets had lower testosterone than men on higher-fat diets. And severe zinc deficiency is a known cause of low testosterone: in one study, restricting zinc lowered testosterone in young men, while zinc supplements raised it in older men who were marginally deficient.

Foods worth eating most days

• Protein at every meal: eggs, meat, fish, Greek yogurt, beans and lentils. Aim for roughly 1.6 g per kg of body weight a day if you’re training. See cheap high-protein foods.
• Zinc-rich foods: oysters (the richest source), beef, poultry, pumpkin seeds, chickpeas and cashews.
• Healthy fats: olive oil, avocados, nuts, eggs and oily fish such as salmon, sardines and mackerel. Fats should be roughly 25 to 35% of your calories.
• Vitamin D sources: oily fish, eggs and fortified foods, plus safe sunlight in summer.
• Magnesium-rich greens and whole grains: spinach, kale, oats and beans.
• Colourful fruit: berries, cherries and pomegranate support overall health and help with fat loss.

Foods and habits to limit

• Alcohol: keep it light. In the UK, the low-risk guideline is no more than 14 units a week, spread over 3 or more days.
• Ultra-processed food: it’s easy to overeat and low in the nutrients above.
• Crash diets: very low calories for long periods lower testosterone. Lose fat steadily instead.

Plant-based? You can still get enough protein and zinc. Our guide to muscle building for vegetarians and vegans shows how.

6. Supplements: what’s worth it

Most testosterone boosters sold online have little evidence behind them. Here’s an honest summary:

Supplement	Evidence	Bottom line
Vitamin D	Raised testosterone in overweight, vitamin D-deficient men over 1 year, but had no effect in men with normal vitamin D.	Worth it if you’re low, especially in winter. The NHS suggests 10 micrograms (400 IU) a day from October to March.
Zinc	Helps when you’re deficient. No proven benefit if your intake is already good.	Get it from food first. Don’t take high doses long-term, because too much zinc can cause copper deficiency.
Magnesium	Linked to testosterone in observational studies; trial evidence is weak.	Fine if your diet is low in it. Not a booster.
Ashwagandha, fenugreek, tongkat ali	Small, mostly short, often industry-funded studies.	Not proven. Check with a doctor or pharmacist, especially if you take other medicines.
“Male enhancement” blends	Some have been found to contain hidden prescription drugs.	Avoid. Buy only from reputable brands.

7. Manage stress

Chronic stress keeps the stress hormone cortisol high, and it also wrecks sleep, appetite and motivation to train. You don’t need a retreat. Ten minutes a day of something that calms you down really helps: a walk outside, slow breathing, stretching or simply phone-free time. If stress shows up in the bedroom too, our guide to performance anxiety in men has practical steps.

How long does it take to raise testosterone naturally?

Sleep changes can make a difference within a week or two. Fat loss and strength training take longer, usually 8 to 12 weeks before you’ll notice more energy, better workouts and a higher sex drive. A useful rule: if your waist is shrinking, your lifts are going up and you’re sleeping 7+ hours, your hormones are almost certainly moving in the right direction. Results vary from man to man.

Frequently asked questions

What is the fastest natural way to increase testosterone?

For most men the biggest quick win is sleep: in a University of Chicago study, one week of 5-hour nights cut daytime testosterone by 10 to 15%. After that, losing excess body fat has the largest effect, followed by regular strength training and fixing any vitamin D or zinc deficiency. Expect changes over weeks to months, not days.

Which exercises boost testosterone the most?

Heavy compound lifts that use a lot of muscle, such as squats, deadlifts, presses and rows, cause the biggest short-term rise. The rise after a workout is temporary, so the real benefit comes from training consistently 2 to 4 times a week, building muscle and losing fat.

Do testosterone booster supplements work?

Most over-the-counter boosters have little good evidence behind them. Vitamin D and zinc can help if you are actually deficient, but they don’t raise testosterone in men with normal levels. Products sold for ‘male enhancement’ are sometimes found to contain hidden drugs, so be careful and ask a pharmacist or doctor.

Can too much exercise lower testosterone?

Yes. Very high training volume combined with too little food and sleep can lower testosterone. If you feel constantly tired, lose motivation to train and stop making progress, take a lighter week, eat enough and prioritise sleep.

When should I get my testosterone checked?

See a doctor if you have ongoing symptoms like very low sex drive, erection problems, loss of morning erections, low energy, low mood or loss of muscle despite training. Diagnosis needs symptoms plus at least two low early-morning blood tests.

The bottom line

To increase testosterone naturally, start with the basics that have the strongest evidence: sleep 7 to 9 hours, lose excess body fat, lift weights 2 to 4 times a week, eat enough protein, healthy fat and zinc, keep alcohol light and manage stress. Skip the hype supplements, fix real deficiencies, and get a blood test if symptoms don’t improve.
