Cutting is when you're most likely to lose the muscle you worked hard to build.
When you eat fewer calories than you burn, your body looks for energy wherever it can find it. Some of that energy can come from muscle. The goal of a good cut is to lose fat while holding on to as much muscle as possible.
Here are six rules that make that happen.
1. Keep lifting heavy
The biggest mistake people make on a cut is switching to light weights and high reps to "tone up." Heavy training is the signal that tells your body the muscle is still needed. Remove that signal and your body has less reason to keep it.
Keep your main lifts heavy. You can reduce total volume a little if recovery suffers, but keep the intensity.
2. Eat more protein than you think you need
Protein needs go up in a calorie deficit. Research on lean, trained athletes suggests intakes of about 2.3–3.1g of protein per kilogram of lean body mass during a cut.
Spread it across 3–5 meals so your muscles get a steady supply throughout the day.
3. Don't cut too fast
Aggressive deficits lead to more muscle loss. A common guideline is to aim for losing about 0.5–1% of your body weight per week. Slower is usually better for keeping muscle, especially if you're already lean.
4. Protect your sleep
Poor sleep makes it harder to recover and easier to lose muscle in a deficit. Aim for 7–9 hours. It's the cheapest recovery tool you have.
5. Keep taking creatine
Some people drop creatine on a cut because of the small amount of water weight it adds. That's a mistake. Creatine helps you keep training heavy when energy is low, which supports rule #1.
The water creatine holds is inside the muscle, not under the skin. It isn't fat.
6. Add HMB
This is where HMB earns its place. HMB is a compound your body makes from leucine, and it's studied for its role in slowing muscle protein breakdown. Calorie deficits are exactly the kind of stress where breakdown increases. Direct research on HMB during dieting is still limited, but that mechanism is why it's worth considering.
Creatine helps you keep your strength up. HMB helps defend the muscle underneath it.

Your cutting checklist
-
Lift heavy, 3–5 days a week
-
Eat 2.3–3.1g of protein per kg of lean body mass
-
Lose 0.5–1% of body weight per week
-
Sleep 7–9 hours
-
Take 5g creatine daily
-
Take 1.5g HMB daily
Make it one scoop
CHAMA combines 5g of creatine monohydrate and 1.5g of HMB in a single daily scoop, so the last two rules take ten seconds. Every batch is TruShield Certified for purity and banned substances, which matters if you're cutting for a weigh-in.
Lose the fat. Keep the muscle.
FAQ
Can you build muscle while cutting? It's possible for beginners and people returning to training. For most experienced lifters, the realistic goal is keeping the muscle you have.
Should I stop taking creatine when cutting? No. Creatine supports training performance, which helps you keep muscle during a deficit.
How do I know if I'm losing muscle on a cut? Watch your strength. If your main lifts drop sharply, you may be cutting too fast or not eating enough protein.
