What is the best macro split for cutting?

There's no single best split. Start with high protein (0.7–1.0 g per pound), a minimum fat intake for hormone health (around 0.3–0.4 g per pound), and fill the rest of your calorie deficit with carbs based on preference and training needs.

How much protein do I need when cutting?

A common range is 0.7 to 1.0 grams per pound of body weight. Leaner individuals or those in aggressive deficits should aim toward the higher end to preserve muscle during fat loss.

Should I go low-carb or low-fat when cutting?

Either can work. After setting protein and a minimum fat intake, allocate remaining calories to carbs or fat based on what keeps you satisfied and supports your training. Personal preference matters more than the ratio itself.

How do I know if my cutting macros are working?

Track your weight, gym performance, and hunger over two to three weeks. If you're losing 0.5–1% of body weight per week and maintaining strength, your macros are likely on target. Adjust if progress stalls or you feel unusually fatigued.

Can I change my macros during a cut?

Yes. As your cut progresses, you may need to adjust calories or shift the carb-to-fat ratio based on energy levels, training volume, and how your body responds. Macros aren't set in stone.

Macros for Cutting: How to Set Your Targets for Fat Loss

Start with a Calorie Deficit

A calorie deficit is the foundation of any cut. Macros matter, but only after you've set your total calorie target. To lose fat, you need to eat fewer calories than your body burns. A typical deficit sits between 15 and 25 percent below your maintenance calories, though individual needs vary based on activity level, metabolism, and how much fat you have to lose.

Slower cuts—closer to a 15 percent deficit—preserve more muscle and feel more sustainable. Aggressive deficits risk losing lean mass along with fat, especially if protein isn't high enough. There's no single prescription that works for everyone; start conservatively and adjust based on how your body responds over a few weeks.

Set Protein High to Preserve Muscle

Protein is the most important macro during a cut. It protects lean tissue when you're in a deficit and keeps you fuller longer. A common range is 0.7 to 1.0 gram per pound of body weight. If you're leaner or running a more aggressive deficit, aim toward the higher end. If you have more fat to lose and are cutting slowly, the lower end may be enough.

Protein also has the highest thermic effect of food, meaning your body burns more calories digesting it compared to fat or carbs. Setting protein first ensures you're doing everything you can to hold onto muscle while the scale drops.

Allocate Fat and Carbs to Preference

Once protein is locked in, the remaining calories get split between fat and carbohydrates. There's no magic ratio here—it comes down to personal preference, training style, and how you feel day to day.

Set a minimum for fat to support hormone health, typically around 0.3 to 0.4 grams per pound of body weight. Beyond that floor, you can tilt higher-carb if you train hard and want the performance boost, or moderate-to-higher fat if that keeps you satisfied and energized. Some people do better on more carbs; others feel sharper with more fat. Both approaches work as long as calories and protein are dialed in.

Carbs support training performance and recovery, especially for higher-volume or higher-intensity work. Fat supports satiety and makes meals taste better. Experiment within your calorie budget and see what feels sustainable.

Example Macro Ranges for Cutting

Here's what macros might look like for a 180-pound person in a moderate deficit. These are illustrative ranges, not a prescription.

Protein: 125–180 g (0.7–1.0 g per pound)
Fat: 50–70 g (roughly 0.3–0.4 g per pound)
Carbs: Fill the rest of your calorie budget

If your deficit lands you at 2,000 calories per day and you set protein at 150 g (600 calories) and fat at 60 g (540 calories), you'd have 860 calories left for carbs—about 215 g. That's one possible split. Another person might prefer 140 g protein, 70 g fat, and 200 g carbs at the same calorie total. Both work.

Individual needs vary. A taller, more active person will have higher absolute numbers. A smaller person will have lower ones. Use these as a starting point, not a rule.

Adjust Based on Progress and Feel

Set your initial macros, then track weight, performance, and hunger over two to three weeks. If you're losing weight too quickly or feeling weak in the gym, add a few hundred calories back—usually from carbs. If you're not losing weight, double-check your tracking accuracy before cutting calories further. Small errors in portion sizes or forgotten snacks add up fast.

Macro ratios can shift as your cut progresses. You might start moderate-carb and later tilt higher-fat if training volume drops, or vice versa. The goal is sustainable progress, not rigid adherence to a ratio you set on day one.

If you're also practicing intermittent fasting, the same principles apply—you're just fitting your macros into a shorter eating window. Macros for intermittent fasting walks through how to set targets when your meals are time-restricted.

How Punkin Helps You Hit Your Targets

Once your macros are set, the daily challenge is deciding what to eat that actually fits. Punkin suggests meals and snacks based on your remaining calories, protein, carbs, and fats. It remembers what you like, what you have in the pantry, and how much time you have to cook.

A macro tracker logs what you've eaten so far; Punkin goes a step further and tells you what to eat next. Barcode scanning speeds up logging for packaged foods, and the app adjusts recommendations as your day unfolds. If you've got 30 grams of protein and 400 calories left before bed, it'll suggest options that fit—not a generic meal plan you have to reverse-engineer.

The free tier gives you meal suggestions and basic tracking with no time limit. New accounts get a 7-day trial of Punkin Premium, which includes advanced features like restaurant recommendations and deeper preference memory. The trial doesn't auto-bill; on day eight your account reverts to the free tier unless you choose to subscribe. Punkin Premium is $7.99/mo or $79.99/yr.
