Cutting Nutrition Guide What to Eat on a Cut
When you are in a calorie deficit, every food choice matters. This guide shows you how to structure your meals for maximum satiety, muscle preservation, and adherence.
Quick Guide
Build each meal around a lean protein source, fill half your plate with vegetables, add a moderate portion of slow-digesting carbs, and include a small amount of healthy fat. Target 2.0-2.4 g protein per kg of body weight, and distribute your protein across 4-5 meals.

Based on your saved assessment, here is how your daily nutrition breaks down:
2. Food Focus for Cutting
When calories are limited, every bite needs to pull double duty. Prioritize foods that are high in protein and fiber while being low in energy density.
| Category | Prioritize | Limit |
|---|---|---|
| Protein | Chicken breast, turkey, fish, egg whites, Greek yogurt, tofu | Fatty cuts of meat, full-fat dairy in excess |
| Vegetables | Leafy greens, broccoli, cauliflower, zucchini, bell peppers, asparagus | Starchy vegetables in large portions |
| Carbs | Oats, quinoa, sweet potatoes, brown rice, legumes | White bread, sugary cereals, pastries |
| Fats | Avocado, olive oil, nuts in moderation, fatty fish | Fried foods, heavy cream, butter in excess |
Pro Tip
Volume eating works: a 300 g serving of broccoli has ~100 kcal and fills your plate. The same calories in olive oil is barely a tablespoon. Prioritize food volume for satiety.
3. Meal Distribution
How you distribute your calories across meals affects satiety, energy levels, and muscle protein synthesis. A balanced approach works best for most people.
Breakfast
25%
of daily calories
Lunch
35%
of daily calories
Dinner
30%
of daily calories
Snacks
10%
of daily calories
Protein should be distributed evenly: aim for 30-40 g per meal. This maximizes muscle protein synthesis throughout the day.
4. Eating Situations
Real life does not always allow for perfectly prepared meals. Here is how to handle common situations while staying on track.
Eating Out
- Choose grilled over fried proteins
- Sauces and dressings on the side
- Water or unsweetened beverages
- Estimate portions using hand sizes
Office Lunch
- Pack lunch when possible
- Choose protein-first options from menus
- Watch dressings and hidden calories
- Keep healthy snacks at your desk
Busy Schedule
- Batch prep proteins (chicken, eggs, fish) for 3-4 days
- Overnight oats for grab-and-go breakfast
- Protein shakes as meal backup
- Pre-portion snacks into containers
Vegetarian
- Combine complementary proteins (rice + beans, tofu + quinoa)
- Target higher total protein (2.0-2.2 g/kg)
- Include soy products (tofu, tempeh, edamame)
- Consider a leucine supplement if needed
5. Beyond Macros
Macronutrients get most of the attention, but several other factors determine success during a cutting phase.
Fiber
Target 25-35 g daily from vegetables, fruits, legumes, and whole grains. Fiber slows digestion, improves satiety, and supports gut health during calorie restriction.
Water
Drink 3-4 L of water daily. Adequate hydration supports metabolism, reduces hunger signals, and improves training performance. Drink 350-500 ml before meals.
Fruit & Vegetables
Aim for 5+ servings of fruits and vegetables daily. They provide micronutrients, antioxidants, and fiber with minimal calorie impact. Prioritize variety across colors.
Meal Frequency
3-5 meals per day works for most people. Choose a frequency that fits your schedule and hunger patterns. Protein distribution matters more than meal count.

7. Frequently Asked Questions
How big should my deficit be for cutting?
A deficit of 15-25% below maintenance TDEE is the standard recommendation for body composition. This typically translates to 300-500 kcal below maintenance. Deficits larger than 25% accelerate muscle loss without significantly faster fat loss over time.
What protein intake is best during a cut?
Protein requirements increase during a deficit. Aim for 2.0-2.4 g per kg of body weight (0.91-1.09 g/lb) to defend against muscle loss. This is higher than the general recommendation of 1.6-2.2 g/kg for maintenance phases.
Can I build muscle while cutting?
Significant muscle gain in a deficit is unlikely for experienced lifters. Beginners and detrained individuals can experience recomposition with high protein (2.0-2.4 g/kg), a modest deficit, and consistent resistance training.
What foods keep me full in a deficit?
Prioritize high-protein foods (lean meats, fish, eggs, Greek yogurt), high-fiber vegetables (leafy greens, broccoli, cauliflower), and slow-digesting carbohydrates (oats, quinoa, sweet potatoes). These maximize satiety per calorie.
How fast will I lose weight?
A sustainable rate is 0.5-1.0% of body weight per week. Track weight trends over 3-4 weeks rather than daily fluctuations. Recalculate your targets after every 5 kg of weight loss.
