Six weeks into treatment I tried to keep my normal training program. I'd been lifting four days a week for years, and the idea that I'd have to drop it felt like another concession to a disease I was already conceding too much to. I made it through three sessions before my body told me, quite clearly, that it wasn't 25 years old and it was now also fighting something. The fourth session I sat in my car in the gym carpark and didn't go in. That was the day I started building a different version of training. Smaller. Smarter. Designed for someone whose body had a job to do that wasn't lifting.
This module is about the daily mechanics of living with a diagnosis. Training, food, alcohol, sleep, work, rest. What to keep, what to drop, what gets harder before it gets easier, and what's worth fighting for even when it costs you.
The principle: the body is now an asset, not a backdrop
Before the diagnosis, your body was the thing carrying you around while you got on with life. After it, your body is the project. It's the asset that's going to either tolerate treatment or struggle with treatment, recover well or recover slowly, and the things you do daily either feed that asset or borrow from it.
This is not self-care. This is operations.
The four levers, in priority order:
- Sleep. Always sleep first.
- Food. Enough of it, the right kind.
- Movement. Less than before, more than nothing.
- Alcohol. Less, often a lot less.
Get those four right and most of the rest of life calibrates to them.
Training during treatment: what to keep, what to drop
The instinct splits two ways and both are wrong. One half of men try to train through it the way they always have and burn out. The other half stop entirely, lose the habit, and arrive on the other side of treatment as a different (worse) version of themselves.
The middle position, which actually works:
Train less, train often. Three short sessions a week beat one heroic one. Forty minutes is a session. Twenty minutes is a session. Showing up matters more than the workload.
Drop the ego lifts. Whatever you used to one-rep-max is not the lift to chase right now. Cut your working weights by 30-50 percent. The aim is movement, blood flow, muscle retention, mental rhythm. It is not a PB.
Keep the compound lifts where you can. Squat, hinge, push, pull, carry. Light versions, full range. They keep the wiring intact better than machines do.
Add walking, deliberately. A 30-40 minute walk most days has compounding effects on mood, recovery, sleep and digestion that no other intervention matches. It is the single most useful non-medical thing you can do, and it costs nothing.
Drop conditioning if treatment is hammering your cardiovascular system. Chemo, certain heart medications, post-surgery recovery: high-intensity work can be counterproductive. Walk instead. Easy bike. Zone 2 only. If your specialist hasn't told you what's safe, ask them directly.
Two weeks into a new training shape, write down how you feel. Compare it to the version of you that was either over-training or not training. The right shape is the one where you're sleeping better and the gym doesn't feel like another battle.
Food: enough, with intent
Most men under-eat during treatment. Two reasons: appetite drops, and the cultural script around being sick says to eat less. Both are wrong for almost every diagnosis.
The body, mid-treatment, is healing. Healing requires calories and protein. Cutting both makes the recovery slower and the muscle loss worse.
The minimum framework:
- Three meals, every day, even if small. Skipping is the first habit to lose.
- Protein at every meal. A palm-sized portion of meat, fish, eggs, dairy, tofu or pulses. Body weight in pounds, target that many grams per day if you can.
- Carbohydrate at every meal. Bread, rice, oats, potato, fruit. Carbs are not the enemy when your body is fighting something.
- Vegetables, at least twice a day. Whatever you'll actually eat. Frozen counts. Tinned counts.
- Fluids. Water, tea, soup, the unsexy ones. Two litres is the floor. Treatment dehydrates.
If specific treatments wreck your appetite (chemo nausea, post-surgical recovery, gut-affecting meds), shift to smaller, more frequent meals. Five small things beat three big things you can't face. A protein shake counts when food doesn't.
A note on the diet-as-cure marketplace. Cancer cookbooks, alkaline diets, juice cleanses, keto-as-treatment, ivermectin, every other corner of the internet: ignore most of it. The interventions with actual evidence (Mediterranean-style eating, adequate protein, adequate calories, limited alcohol) are dull and well-known. The exciting ones are mostly people selling books. Run anything dramatic past your specialist before you adopt it.
Alcohol: the honest version
The honest version is that alcohol is harder to keep at the same level during a serious diagnosis than almost anything else. Here's why.
It's the closest thing most men have to a daily emotional valve. The diagnosis turns up the pressure. The valve gets used more. Six weeks in you're drinking more than you used to and feeling worse, on top of treatment, and the relationship between the two is not obvious in the moment.
The case for cutting it back, hard, during treatment:
- Most chemo drugs interact with alcohol. The interactions range from mild to genuinely dangerous. Ask your oncologist.
- Alcohol disrupts sleep architecture. The same beer that knocks you out at 10pm wakes you at 3am. You need the deep sleep more than you need the wind-down.
- The liver is already metabolising treatment drugs. Adding alcohol to the queue is asking more of an organ that's already working overtime.
- Mood-wise, alcohol is a depressant. Treatment is depressing enough without amplification.
The protocol that works for most men is not zero. It's a structured low. Two or three drinks a week, all on weekends, none in the week. Or a complete dry stretch through the most intense part of treatment, then small amounts on the other side. The aim is to keep alcohol from becoming the thing that holds the diagnosis together.
If you're already drinking every night, the diagnosis is the moment to stop using alcohol as an emotional anchor. Find a different anchor. Walking. Reading. A phone call with one of those three mates. Something that doesn't have a hangover attached.
Sleep: the highest-leverage habit
Treatment disrupts sleep in five different ways: the medication, the anxiety, the physical symptoms, the disrupted routine, and the late-night thinking. The result is a sleep deficit that compounds.
Things that actually help:
- A consistent bedtime, within a 30-minute window, every night. The body responds to schedule more than to duration.
- A cold, dark bedroom. Block-out blinds, ear plugs if needed, the thermostat lower than feels reasonable.
- No screens for the hour before bed. The light and the doom-scrolling both work against you.
- A wind-down ritual. Reading, a hot shower, a stretch routine. Something repetitive. The brain learns the cue.
- Magnesium before bed if it works for you. It helps some men, does nothing for others. Cheap to test.
- A short prescription sleeping aid for a hard week, if your GP agrees. Not a long-term answer; a tool for the worst stretches.
What to stop:
- Reading the news in bed.
- Drinking past 8pm.
- Working in bed.
- Lying awake "trying" to sleep for more than 20 minutes. If you're awake, get up, sit somewhere with low light, read until tired, return to bed.
Work: keep the rhythm where you can
For most men, working through treatment (with adjustments) is better for mental health than stopping entirely. Work provides structure, identity, social contact, and a sense of capacity. If you can keep some of it, do.
The shape that works:
- Keep mornings. Most treatments hit hardest in the afternoon. Morning is the productive window.
- Drop the meetings you don't need. Half your meetings were optional anyway. This is the moment to find out which ones.
- Be honest about capacity. Tell your manager when a treatment week is going to be a thin week. Don't promise output you can't deliver.
- Take the actual day off after a hard treatment. Not "I'll work from home and rest." Off. Couch, sleep, nothing.
If you can't keep working, that's information, not failure. The work and money module covers what kicks in.
Three traps in the daily mechanics
The "I'll just power through" trap. Treatment is not a sprint to push through. It's a long road with peaks and troughs. Pacing beats heroics. The men who arrive on the other side intact are the ones who modulated, not the ones who refused to.
The "I'll start eating better when this is over" trap. Now is when it matters most. The body building back from treatment uses the same nutrients that built it the first time. Don't save the protein for a celebration meal that's six months away.
The "I don't deserve to feel good while this is happening" trap. Pleasure is not betrayal. The body is going through enough; let the parts of life that are still good (a good coffee, a long shower, a walk you enjoy, a film with the partner) actually be good. The men who let treatment swallow everything come out the other side hollowed.
The diagnosis is not the only thing happening in your life. It's just the loudest one this year.
Sleep first. Eat enough. Move some. Drink less.
Further watching
- 01Train less, train often. Three short sessions beat one heroic one. Drop the ego lifts. Walk daily.
- 02Three meals, protein at every one, body weight in pounds = grams per day. Healing needs calories.
- 03Cut alcohol back hard during treatment. It interacts with drugs, wrecks sleep and amplifies low mood.
- 04Sleep is the highest-leverage habit. Consistent bedtime, cold dark room, no screens for the hour before.
- 05Pleasure is not betrayal. Let the still-good parts of life still be good. The diagnosis isn't the only thing happening.
