Fast weight loss takes muscle with it unless you give the body a reason to keep it. The reason is simple and it is the same one every sports scientist gives: enough protein, and something heavy to lift a few times a week. Everything on the Move & Recover shelf exists for the second half of that sentence. This page is the whole plan in five short parts.
1. Protein first, every day
The usual target people work to is somewhere around 1.2 to 1.6 grams of protein per kilogram of body weight a day, spread over three or four meals. On a small appetite that is hard from food alone, which is why the whey, clear whey and casein tubs are the first things on the supplements shelf. A shake is not cheating; on a 1,200-calorie day it is the difference between keeping the muscle and not.
2. Lift something two or three times a week
It does not need to be a gym. A set of fabric bands and one kettlebell cover squats, hinges, rows and presses, which is every muscle group that matters. Two or three short sessions a week, eight to twelve slow reps, stop two reps short of failure. Twenty minutes is plenty. The rule that matters more than any exercise choice is that the sessions actually happen.
3. Walk
Steps are the cheapest fat-loss tool there is and they cost no muscle. Seven to ten thousand a day is the range most people settle on. A smart scale and a tape will show you the trend better than the number on any single morning.
4. Recover on purpose
Five minutes on a foam roller after a walk or a session, a heat pack on anything that is stiff, and sleep. Soreness that stops you training is worse than a lighter session. Creatine is the one gym supplement with decades of evidence behind it for strength work, and it is cheap; it is on the shelf as what it is, not as a promise.
5. Measure the right thing
The scale number goes down when you lose muscle too, so it is a poor guide on its own. Use it alongside the tape, the way your clothes fit, and whether the band or the kettlebell got easier. Photos every few weeks beat daily weigh-ins for morale. If you are losing more than about one percent of your body weight a week for a long stretch, more protein and a little more food is usually the fix.
