Q: Do you need to eat more on TRT?

Sometimes, but not automatically. TRT often raises appetite and speeds recovery, and if you're training harder your body genuinely asks for more protein and fuel. But 'more' is driven by your training and goal, not the therapy itself. If you're already lean and not trying to gain, you may not need extra calories — you need better ones. Let hunger and the mirror guide the amount, and let bloodwork keep you honest.

Q: Does TRT make you gain weight?

It can, in three ways that matter completely differently. Early on you may hold water and see the scale jump — that's fluid, not fat, and it usually settles. If you're training, you'll add lean muscle, which is weight you want. And if you eat in a surplus, you'll add fat, same as anyone. The scale alone can't tell these apart. Watch your waist, the mirror over weeks, and your bloodwork, not the morning number.

I’ve been on TRT since I was thirty-five. Five years now. When my doctor and I started it, I half-expected my eating to change completely — some special TRT diet with a new rulebook I hadn’t learned yet. There wasn’t one. What changed was quieter than that, and more useful.

So this is the honest version of the testosterone diet, from a man who’s actually cooked on it: what therapy did to how I eat, what it never touched, and how I set my plate now that I’m on. No protocol talk, no numbers-per-week — that part lives between you and your doctor, and it should. Just food.

I’m a big man who competed back home in Sweden before I ever picked up an apron. I’ve eaten for the stage, eaten for a cut, eaten for nothing but comfort. TRT sits in the middle of all of it now. Let me walk you through what it actually feels like at the table.

What TRT actually changed at my table

The first thing, and the one nobody warns you about, was how steady my appetite got. Before therapy my hunger swung — ravenous one day, no interest the next. On TRT it flattened out into something reliable. I got hungry when I’d trained hard and I got full when I’d eaten enough, and both of those signals started telling the truth. That alone made eating well easier, because I wasn’t fighting my own body for information anymore.

The second thing was recovery. I’d train, and the soreness that used to sit on me for three days packed up in one. That changes what you want to eat. When you recover faster you train more, and when you train more your body genuinely asks for more protein and more fuel. The hunger wasn’t random — it was my muscle doing repair work and sending the bill.

Third: my body started answering the food. Feed a body with healthy testosterone the right protein and a reason to grow, and it puts on lean tissue and lets go of fat more willingly than it did before. That’s not me being poetic — it’s what the research shows. A meta-analysis of fifty-nine controlled trials found testosterone therapy reliably lowered fat mass and raised lean mass.^[1] I felt that as a body that finally cooperated with good eating instead of arguing with it.

And the fourth thing, the one that scared me before I understood it: water. The first couple of months I got puffy. Face rounder, ring tighter, the scale up. I’ll tell you what I did about that further down, because it taught me the single most important lesson of eating on TRT.

I nearly quit in month two. I looked in the mirror one morning in Chicago and my face was soft, the scale was up four pounds in ten days, and I thought I’d done something wrong — eaten wrong, gained fat, ruined it. I called my doctor half-annoyed. We ran bloodwork. The fat calipers hadn’t moved; the water had. My body was holding fluid while it settled into a new normal, and within another month it let most of it go. Four pounds of panic that was never fat. If I’d trusted the mirror over the bloodwork I’d have crash-dieted myself into a hole for no reason.

What TRT did not change: the calories still count

Here’s where I get firm with you, big man, because somebody has to. Testosterone therapy is not a fat-loss drug. It is not a license to eat like the rules stopped applying to you. I’ve watched too many men start TRT, feel that first surge of appetite and recovery, and take it as permission to bury themselves in food — and then blame the therapy when the gut arrives.

The therapy makes your body better at using what you feed it. It does not decide how much you feed it. That’s still you, at the counter, with the pan. Eat five hundred calories a day over what you burn and you will gain fat on TRT the same as you would have off it. The math didn’t leave the room when the testosterone walked in.

What TRT buys you is a better exchange rate. The same honest eating gets you a leaner, stronger return than it used to. But you still have to do the eating. If you’re used to eyeballing your food and hoping, TRT is a good moment to actually learn what a plate weighs — the fundamentals I lay out in the free 7-day plan are the same fundamentals, therapy or not.

Magnus’s rule

TRT changes the exchange rate on your food. It does not do the eating for you. Protein still has to arrive on a plate, and calories still have to add up. Nobody’s testosterone ever counted a macro for them.

Eating for the numbers TRT moves

This is the part that separates eating on TRT from just eating. Therapy nudges a handful of markers on your bloodwork, and your fork has a say in most of them. None of this is medical advice — your doctor reads your labs, not me — but here’s how I set the table around the numbers we watch.

Hematocrit — the thick-blood one

Testosterone tells your body to make more red blood cells. For most men that’s a mild, first-year rise that plateaus; for some it climbs enough that a doctor pays attention.^[4] Food doesn’t control it the way water does — so I drink through the day, every day, and I don’t skip meals or run dry before training. Hydration won’t fix a genuinely high hematocrit (that’s a bloodwork-and-doctor conversation), but staying watered is the cheapest, dumbest-simple thing you can do to not make it worse.

Estrogen — the body-fat one

Here’s a thing most men don’t know: your fat tissue makes estrogen. It carries an enzyme called aromatase that converts testosterone into estradiol, and the more body fat you carry, the more of that conversion happens.^[2] On TRT, with more testosterone in the system, a soft midsection quietly turns more of it into estrogen. The lever you actually control isn’t a pill — it’s your body fat. Stay reasonably lean and you give the aromatase less to work with. Getting lean is an estrogen strategy, not just a mirror strategy.

Blood pressure and lipids — the heart ones

Water retention and thicker blood can nudge blood pressure, and testosterone can shift your cholesterol numbers around. This is bread-and-butter heart eating, nothing exotic: I keep a lid on sodium, lean hard on potassium-rich food (leafy greens, potatoes, beans), and I get most of my fat from fish, olive oil and avocado instead of the fryer. A plate like my salmon and avocado plate is built for exactly this — omega-3 fat, potassium, and no junk riding along.

Marker TRT can move	Which way	What I put on the plate
Hematocrit (red cells)	Up, mostly first year^[4]	Water all day; don’t train dehydrated; let bloodwork lead
Estrogen (aromatization)	Up if body fat climbs^[2]	Stay lean; a leaner body converts less testosterone to estrogen
Blood pressure	Can nudge up	Watch sodium; potassium-rich foods; keep weight in check
Cholesterol / lipids	Can shift	Fish, olive oil, avocado, fiber; less fried food

Notice the through-line: leaner body, more water, better fats. Three of the four markers get quieter when you simply eat well and don’t carry extra fat. That’s the whole secret. TRT doesn’t ask for a strange diet — it asks for a genuinely good one, done consistently, because now the numbers are watching.

What to eat on TRT: building the plate

When men ask me what to eat on TRT, they want a list of magic foods. There isn’t one. There’s a plate structure, and it’s the same sturdy plate I’d build for any lifter — just held to it a little more honestly because of the markers above.

Protein anchors every meal. This is the non-negotiable. Testosterone plus training builds muscle, but only if the raw material shows up. Aim for a real protein source at each meal — 40 grams or so, a palm-and-a-half of meat, fish or eggs. Total for the day, most lifters do well around 1.6 to 2.2 grams of protein per kilo of bodyweight; the research shows gains from added protein flatten out past roughly 1.6 g/kg, so you don’t need to drown in it.^[5] My mornings are often steak and eggs with spinach — protein, iron, greens, done before the kids are up.

Vegetables for fiber and potassium. Half the plate, most meals. This is your blood-pressure and gut insurance, and it’s where the potassium lives. Don’t overthink it — a fistful of something green or colorful next to the protein.

Carbs to fuel the training, not to fill time. Rice, potatoes, oats, fruit — around your sessions, when your muscle actually wants them. TRT recovers you faster, so the training earns real carbs. You don’t need to fear them; you need to aim them.

Fats, mostly the good kind. A thumb of fat per meal from fish, olive oil, nuts, avocado. This is doing double duty on TRT — it’s where you steer your lipids. When I want red meat I’ll do a ribeye with sauteed spinach, but I balance the week with oily fish so my cholesterol numbers stay boring.

Kitchen math

A 200-gram cooked steak is roughly 55–60g of protein. Three whole eggs add about 18g. That’s one breakfast doing most of a day’s minimum for a lot of men. Protein is easier than the supplement aisle makes it sound — you mostly just have to remember to put it on the plate.

The best diet while on TRT is the one you’ll actually run

People want me to crown a winner — is the best diet while on TRT keto, carnivore, Mediterranean, something with a trademark? I’ll be straight with you: the marker data doesn’t care about the label on your diet. It cares that you’re lean-ish, well-watered, eating enough protein, and getting decent fats. You can hit all of that a dozen different ways.

Pick the pattern you’ll still be running in a year. If you love red meat and eggs, build around them and add fish for your lipids. If you’d rather eat like the Mediterranean, wonderful — that’s practically the TRT template already. The best TRT diet plan is the boring one you don’t quit. Consistency moves your bloodwork; novelty doesn’t.

One honest caveat: everything here is for a replacement dose — testosterone therapy that brings a low man back to normal. If you’re running more than that, the appetite, the water and the markers all get louder, and the plate has to change with them. I wrote that up separately in how I actually eat on cycle — different animal, same kitchen.

Alcohol, honestly

I’m not going to pretend I’m dry. I’m a forty-year-old man with a husband and friends, and there’s wine on my table some nights. But I’ll tell you what alcohol does so you can make your own call, because the diet internet lies about this one in both directions.

Alcohol isn’t free. Even moderate drinking lowers testosterone a little in men — a controlled study found a drop of about seven percent from a moderate daily amount.^[3] On TRT your therapy is holding your level up, so a glass of wine isn’t going to sink you the way it might a natural man. But alcohol brings empty calories, wrecks your sleep, and softens your judgment right when the late-night kitchen is open. The real cost is usually the eating that comes with the drinking, not the drink.

My rule for myself: I don’t drink on training-fuel nights, I keep it to a couple when I do, and I never let a drink turn into a meal I didn’t plan. Your doctor may have their own view given your bloodwork — worth asking. No shame in any of it. Just eyes open.

The long game

Five years on, here’s what TRT taught me about eating that I didn’t know at thirty-five: the therapy is a multiplier, and a multiplier does nothing to a zero. Good eating times testosterone is a strong, lean, well-recovered man. Bad eating times testosterone is just a bigger version of the mess you started with, now with bloodwork to prove it.

So I cook. Real protein, real vegetables, water all day, fish through the week, and I keep an eye on the numbers with a doctor who knows me. It’s not a special diet. It’s an honest one, run for years instead of weeks. If you want a place to start that already has the protein and the portions built in, my free 7-day plan will feed you well for a week and show you the shape of it. Come get fed, big man. I’ve got you.

Questions men actually ask

Do you need to eat more on TRT?

Sometimes, but not automatically. TRT often raises your appetite and speeds recovery, and if you’re training harder your body genuinely asks for more protein and fuel. But “more” is driven by your training and your goal, not by the therapy itself. If you’re not trying to gain and you’re already lean, you may not need extra calories at all — you need better ones. Let hunger and the mirror guide the amount, and let bloodwork keep you honest.

What should you avoid when on TRT?

No single food is banned, but a few things earn a closer eye. A chronic calorie surplus that adds body fat works against you twice — the fat itself, and the extra estrogen your fat tissue makes from your testosterone. Heavy sodium and lots of fried food push on the blood-pressure and cholesterol numbers TRT can already nudge. And heavy alcohol undercuts sleep, judgment and testosterone all at once. None of it is forbidden; all of it is worth moderating.

What is the best diet for TRT?

The one you’ll actually stick to that keeps you reasonably lean, well-hydrated, high enough in protein, and getting good fats. Whether that’s Mediterranean, higher-carb, lower-carb or carnivore-leaning matters far less than consistency. Your bloodwork responds to how you eat over months, not to the name of the plan. Pick a pattern you enjoy, build every meal around a protein anchor, and run it long enough to matter.

How do I maximize my TRT results in the kitchen?

Four levers do most of the work: hit your protein every day, stay lean enough to keep aromatization down, drink water consistently, and get your fats from fish and olive oil rather than the fryer. Train to give the testosterone something to build, sleep enough to recover, and review your bloodwork with your doctor so you’re aiming at real numbers instead of guessing. The food doesn’t need to be fancy — it needs to be consistent.

Does TRT make you gain weight?

It can, in three different ways that matter completely differently. Early on you may hold water and see the scale jump — that’s fluid, not fat, and it usually settles. If you’re training, you’ll add lean muscle, which is weight you want. And if you eat in a surplus, you’ll add fat, same as anyone. The scale alone can’t tell these apart. Watch your waist, the mirror over weeks, and your bloodwork, not the morning number.

People hear “steroid diet” and picture something exotic. Some secret stack of foods that only works if you’re on. It isn’t that. When I’m running a cycle heavier than my usual TRT, my kitchen doesn’t turn into a laboratory. It turns into a bigger version of the same honest kitchen it always is: more protein on the plate, more total food, a closer eye on my blood pressure, and the same steak that would feed you just as well as it feeds me.

I’ve been on TRT since I was thirty-five, and now that I’m off the competitive stage I run heavier from time to time. So when I talk about a steroid cycle diet, I’m not reading it off a forum. I’m telling you what actually lands on my table when I’m on, and what changes and what stubbornly refuses to.

Here’s the part nobody selling you a protocol wants to say out loud: the drugs don’t cook. They don’t shop, they don’t weigh your chicken, they don’t decide whether you eat like a man who respects his body or a man who’s hoping the vial does it all. That’s still your job. It’s still mine. Let me walk you through it.

What a steroid diet actually is (and what it isn’t)

A steroid diet is just good lifting nutrition, turned up to match what your body can now do with the extra food. That’s the whole trick. Enhanced or not, muscle is built out of protein, energy, and hard training. Being on cycle changes how much of the first two you can put to work and how fast you recover. It does not hand you a shortcut around eating well.

What it is not: it’s not a licence to eat garbage and grow anyway. It’s not a magic macro ratio. And it’s for damn sure not an excuse to skip your bloodwork. If someone’s selling you a “steroid cycle diet” that’s really a dosing plan with a grocery list stapled to it, close the tab. I’m here for the food and the numbers on your plate. Where you get anything, and how much of it, is between you and a doctor who’s actually seeing your labs — not me, and not a stranger at the gym.

Magnus’s rule

Smaller doses and a full, honest plate beat big doses and a chaotic one. Every time. The men I’ve watched get hurt weren’t the ones who ate too much broccoli. More was never the answer for me, and food-first was.

What changes on my plate when I’m on

Three things move the moment a heavier cycle kicks in, and they’re worth naming plainly.

Appetite. Hunger goes up, sometimes hard. On testosterone I can eat like the sixteen-year-old who first got off the boat in Chicago. That’s a gift and a trap. It means hitting a big protein target feels easy instead of a chore — but it also means the same appetite will happily bury you in food that does nothing for you if you let it drive. I let the hunger fuel the plates I planned, not the ones the vending machine planned.

Protein target. I eat more protein on cycle, plainly because I can build with more of it. For a natural lifter the research keeps landing around 1.6 grams of protein per kilogram of bodyweight per day as the point where extra protein stops adding muscle.^[1] When I’m on, I sit at the top of the honest range — think 2.0 to 2.2 g/kg, the upper end the off-season research uses for hard-training bodybuilders^[2] — because recovery is faster and there’s simply more building happening to feed. For a 100 kg man that’s roughly 200 to 220 grams a day. Not heroic. Just consistent.

Food volume. More muscle recovering and more appetite means more total food. A modest surplus of maybe ten to twenty percent over maintenance is where lean tissue gets built without me turning into a water balloon^[2] — and honestly, the exact surplus number is fuzzier in the science than the gurus pretend^[3], so I watch the mirror and the scale, not a spreadsheet. Big calories that stay clean is the real skill here. That’s why my on-cycle plates lean on foods that are dense but honest, like a proper ribeye with rice and broccoli or a stack of high-volume beef and rice power bowls when I need the calories to disappear easily.

The thing to guard against is letting the appetite decide the menu. On a heavy week I plan the day the night before — I know what’s going in every one of those five meals, and I’ve cooked most of it in advance. Prep is what keeps a big-appetite day from turning into a big-mistake day. When the hunger hits at four in the afternoon and there’s already a bowl in the fridge, you eat the food that builds you. When there’s nothing prepped, you eat whatever’s nearest, and on cycle “whatever’s nearest” adds up fast. My kitchen does more for my results than any part of my week that isn’t the gym.

Do you need more protein on cycle?

Yes — but less than the internet screams, and here’s the honest reason. Protein is the raw material. Being on lets your body assemble that material faster and waste less of it, so more of what you eat actually becomes tissue. The distribution matters as much as the total: the sports-nutrition consensus is to spread it across the day in feeds of roughly 0.25 g/kg, or 20 to 40 grams a sitting, every three to four hours.^[4] That’s four or five real meals for most of us, not one giant shake and a prayer.

What I don’t do is treat protein as the only lever. Carbs fill me out, fuel the sessions that actually cause growth, and keep me sane. Fat keeps my hormones and my joints happy. A day built only on chicken breast and white rice will technically hit macros and quietly wreck your bloodwork and your mood. I’d rather you ate chicken thighs with rice and beans — fattier meat, real fibre, food that feeds a man — than choke down another dry, sad breast because someone online told you thighs were “dirty.” They aren’t. There’s no such thing.

Sodium, water, and the puffy face

This is the one men skip, and it’s the one I watch hardest. Many compounds hold water. Add a salty diet on top and you get the puffy face, the tight rings, the blood pressure creeping up where you can’t see it. High sodium intake pushes blood pressure up, and cutting back by even 1,000 mg a day measurably helps most people; the American Heart Association puts the ceiling at 2,300 mg and the ideal nearer 1,500 mg.^[5]

I’m not telling you to eat bland. I’m telling you where the salt actually hides — the sauces, the deli meat, the restaurant everything — and to cook enough of your own food that you’re the one holding the salt cellar. When I’m on, I keep potassium up with real potatoes, greens and fruit, drink my water honestly, and salt my own cooking to taste instead of eating whatever a factory decided. The puffy face usually isn’t the drug. It’s the drug plus a diet full of hidden sodium.

Eating for your bloodwork

When I’m on, my food choices answer to my labs, not the other way around. Three markers do the steering.

Blood pressure. The sodium story above, plus keeping bodyfat and stress in check. I take my BP at home when I’m on. If the cuff talks, the kitchen listens.
Lipids. Cycles can drag cholesterol around, so I lean into the foods that help — oily fish, olive oil, oats, plenty of fibre and colour — and I don’t pretend a stack of egg-white-and-bacon breakfasts is neutral. This is where fattier cuts get portioned with a bit more thought, not banned.
Liver. If any orals are ever in the picture, I keep the liver’s workload light: alcohol out, real food in, and nothing exotic sold as a “detox.” Whole food and water do more than any bottle of pills promising protection.

The pattern across all three markers is the same: whole food helps, hidden ingredients hurt, and the man who cooks most of his own meals has the most control over what his labs say. I’m not eating differently on cycle because the compounds demand strange food. I’m eating the same real food more carefully, because there’s more riding on the numbers.

None of this replaces a doctor. Get your bloodwork done before, during, and after — full stop. I cook and I count; I don’t diagnose. The plate is a tool for keeping your numbers quiet, not a substitute for reading them.

From the stage

Backstage in Sweden, standing there in bronzer at the B&K Classic, I learned the thing that still runs my kitchen: the man who peaks isn’t the one who found the best compound. It’s the one whose food and training were dialled for months. The rest is garnish.

The drugs don’t cook — the research is blunt about it

I want to show you a number, because it’s the whole point. In the classic 1996 trial, men were given either testosterone or a placebo, with or without training, for ten weeks. The group that took testosterone without lifting gained real strength — about 9 kg on the bench. Respectable. But the group that took the same testosterone and trained gained 22 kg on the bench, and 6.1 kg of fat-free mass.^[6] More than double, from the same drug, because they did the work.

Read that again. The compound alone gave a fraction of what the compound plus training gave. And training doesn’t happen without food — you can’t recover from work you can’t fuel. That’s the honest hierarchy: the drug raises your ceiling, but your training and your plate decide how much of that ceiling you actually reach. This is exactly why the same rules I give a natural lifter over fifty in my guide to building muscle after 50 still apply to me on my heaviest week. The biology of a fork doesn’t care what’s in your bloodstream.

The leanest, strongest I ever looked, I wasn’t running anything clever. I was cooking every meal, weighing my food, taking my blood pressure on Sunday nights at the kitchen table while the kids did homework, and training like it mattered. The years I chased it through the vial instead of the kitchen, I looked worse and felt worse. My husband will tell you: I’m a better-built man when I’m a better cook. That’s not a slogan. That’s just what the mirror keeps telling me.

On cycle vs off cycle, at my table

Here’s what genuinely shifts when I go from my normal TRT baseline to a heavier block, for a man around 100 kg. Note how little the foods change — it’s the volumes and the vigilance that move.

At my table	Off / TRT baseline	On a heavier cycle
Protein	~1.6 g/kg (~160 g)	~2.0–2.2 g/kg (~200–220 g)
Calories	Maintenance to slight surplus	~10–20% surplus
Meals a day	4	4–5, bigger
Sodium	Sensible	Watched hard; salt my own food
Blood pressure	Checked periodically	Checked at home, weekly
Bloodwork	Routine	Before, during, after
The actual foods	Almost identical — steak, rice, eggs, thighs, potatoes, fish, greens

If you take one thing from the table, take the bottom row. The kitchen barely changes. A smart bulking approach on cycle is the same one off it, just scaled to the appetite and watched a little closer. You already know how to cook the food that builds you. Being on just means you get to eat a bit more of it and you owe your bloodwork a bit more respect.

Questions men actually ask

What should I eat while on steroids?

The same honest lifting food you should eat off them, scaled up: a high protein target spread across four or five meals, enough carbs to fuel hard training, real fats for your hormones and joints, and plenty of fruit, veg and fibre for your bloodwork. Steak, rice, eggs, chicken thighs, potatoes, oily fish, greens. Nothing exotic. The change on cycle is mostly volume and keeping a closer eye on sodium and blood pressure — not some secret food list.

Can you eat eggs on steroids?

Yes, absolutely. Whole eggs are one of the best foods you can eat on or off cycle — a large egg runs about 6 grams of complete protein, plus the fats and micronutrients that keep you running. The only thing worth watching is your lipid panel over time, so if your cholesterol is trending high, get your labs done and talk to your doctor about balance. That’s a bloodwork conversation, not a reason to fear the humble egg.

Do you need more protein on cycle?

A bit more, yes, because being on lets your body build faster and use more of it. Natural lifters do well around 1.6 g/kg a day; on a heavier cycle I sit nearer 2.0 to 2.2 g/kg, the upper end the off-season research uses. For a 100 kg man that’s roughly 200 to 220 grams, spread across the day in 20 to 40 gram feeds. More than that isn’t buying you extra muscle — it’s just expensive.

Can you eat junk and grow anyway?

You’ll grow something. Being on is forgiving enough that you can gain on a sloppy diet — for a while. But you’ll gain more fat, feel worse, and quietly punish your blood pressure, cholesterol and mood while you do it. The trial data is clear that the work you put in decides most of your result, and junk food undercuts the training and recovery that work depends on. You can get away with it. You just won’t like what you get.

Does diet matter more on cycle or off?

It matters just as much — arguably more, because the stakes on your health markers are higher. Off cycle, bad eating mostly costs you progress. On cycle, it costs you progress and stacks on top of compounds that are already asking more of your heart, lipids and liver. That’s the time to cook the most of your own food, not the least.
