Why most cuts cost strength
When people lose strength on a cut, it’s usually for one of three reasons: they lose weight too fast, they stop lifting heavy (“lighter weights, more reps to tone”), or they under-eat protein. All three are fixable.
1. Set a sensible rate
The NHS describes losing 0.5kg to 1kg a week as a safe and sustainable rate. I treat the top of that range as a ceiling, not a target. Faster than that and the deficit usually starts eating into training quality, recovery and muscle.
2. Keep lifting heavy
Heavy training is the signal that tells your body the muscle is still needed. Keep the main lifts in your programme at similar intensities; if anything drops during a cut, let it be total volume, not the weight on the bar. Holding your strength is a win in a deficit.
3. Eat enough protein
Protein does two jobs on a cut: it helps preserve muscle, and it keeps you fuller. A widely cited meta-analysis found benefits for muscle levelling off at around 1.6g of protein per kg of bodyweight per day for people who train — and some research on people in a deficit points a little higher. Spread it across meals rather than saving it for dinner.
4. Make the deficit boring
The cut you finish beats the perfect cut you abandon. Most of the work is unexciting: regular meals, mostly familiar foods, a plan for weekends, and no food banned outright.
5. Treat sleep as part of the programme
Short sleep makes hunger harder to manage and recovery worse. It’s often the difference between a cut you finish and one you abandon.
How to set up the deficit
You don’t need a calculator to start. For a couple of weeks, eat as you normally do, log it roughly, and weigh yourself most mornings. If your weight is stable, that’s your maintenance. Then eat a modest amount less — enough for the weekly average to come down at your target rate. If it drops faster than 1kg a week, eat a little more; if it stalls for two or three weeks, eat a little less.
Track the weekly average, not the day
Bodyweight moves around from day to day with water, salt, carbohydrate and digestion. A single morning tells you almost nothing. Compare this week’s average with last week’s. That one habit stops a lot of people quitting a cut that was actually working.
Know when the cut ends
Decide the end point before you start — a date, a weight, or a look — and then move to maintenance deliberately rather than drifting back up. Bring calories up gradually over a week or two, keep lifting heavy, and let your weight settle. A cut is a phase, not a lifestyle.
What this looked like for Habeeb
Habeeb trains with me at Definition in Peterborough. Over a four-month cut he went from 85.40kg to 74.42kg — 10.98kg, averaging 1.00kg a week — with strength training kept heavy the whole way through. He came out of it still lifting. Read Habeeb’s story.
