Protein, carbs, and fats for your goals
🥗 What are Macros? Macronutrients = protein, carbs, fats. They make up every calorie you eat. Fiber (not a macro but essential!) is in the carbs section — aim for 25-38g/day for gut health.
Alcohol is sometimes called the "fourth macronutrient" — it provides 7 calories per gram, more than protein or carbs but less than fat, yet it's not classified as an essential nutrient since the body doesn't need it to survive.

What are Macronutrients? Macronutrients, or "macros," are the three main nutrients that provide calories: protein (4 calories per gram), carbohydrates (4 calories per gram), and fat (9 calories per gram). Getting the right balance of each is essential for energy, muscle building, hormone production, and overall health.
How It's Calculated: This calculator takes your daily calorie needs (from TDEE) and divides them based on your goal. For weight loss, a typical split is 40% protein, 35% fat, 25% carbs. For muscle building, 30% protein, 50% carbs, 20% fat. For maintenance, a balanced 30% protein, 40% carbs, 30% fat works well.
Protein: The Muscle Builder: Protein is essential for muscle repair and growth, enzyme production, and immune function. The calculator uses 0.8-1g per pound of body weight as a baseline, adjusting for your activity level and goals. Good sources include meat, fish, eggs, dairy, legumes, and plant-based proteins.
Carbohydrates: Your Energy Source: Carbs are your body's primary fuel source, especially for high-intensity activities. The calculator prioritizes carbs for active individuals. Choose complex carbs (whole grains, vegetables) over simple sugars for sustained energy and better blood sugar control.
Fats: Hormone and Brain Health: Dietary fat is crucial for hormone production, vitamin absorption, and brain function. The calculator ensures you get adequate healthy fats. Focus on unsaturated fats (avocados, nuts, olive oil) while limiting saturated and trans fats.
Using Your Results: Start with the calculated macros and track your food for a week. Adjust portion sizes to hit your targets. Remember that these are starting points—individual responses vary. Re-calculate every 4-6 weeks as your weight changes or your goals shift.
Example: Say you weigh 150 lb, want to Maintain, and are Moderately active. Protein: 150 × 1.1 = 165g (660 cal). Fat: 150 × 0.35 = 53g (477 cal). Remaining calories fill in carbs at 4 cal/g — landing you around 165g protein / 53g fat / and the rest in carbs to hit your daily total.
Protein is set at about 1.1g per pound of body weight, fat at about 0.35g per pound, and the remaining calories after protein and fat are filled with carbs, based on your estimated daily calorie needs and goal.
A typical weight-loss split is around 40% protein, 35% fat, and 25% carbs, though individual needs vary based on activity level and personal preference.
Every 4-6 weeks, or whenever your weight, activity level, or goals change significantly — your macro needs shift as your body composition changes.
