Read ThirdThe Role of Nutrition in Fitness
Training tells your body what to build, but nutrition provides the raw materials. Your TDEE determines how many calories you burn — eat more to gain, less to lose, or match it to maintain. Getting this energy balance right matters more than any supplement or meal timing strategy.
Protein is the most important macronutrient for body composition (1.6–2.2 g/kg for active lifters). Start simple: hit a daily protein target, eat mostly whole foods, and build consistency before worrying about advanced strategies. The articles below cover everything from calories and macros to meal prep and supplementation.

Frequently Asked Questions
How many calories should I eat to lose weight?
To lose weight, you need a caloric deficit — eating fewer calories than your body burns. Use a TDEE calculator to find your maintenance calories, then subtract 300-500 calories for steady fat loss of 0.5-1% bodyweight per week. Larger deficits risk muscle loss and metabolic adaptation.
How much protein do I need per day for muscle growth?
Research consistently supports 1.6-2.2g of protein per kg bodyweight (0.7-1g per pound) for muscle growth. Use our protein calculator for a personalized target. Beginners and those in a caloric deficit benefit from the higher end of this range. Read our protein guide for beginners for practical strategies.
What are macros and why do they matter?
Macros (macronutrients) are the three calorie-providing nutrients: protein (4 cal/g), carbohydrates (4 cal/g), and fat (9 cal/g). While total calories determine weight change, macro ratios affect body composition, energy, and performance. Use our macro calculator to find your ideal split based on your goals.
Should I eat more to build muscle (bulk) or less to lose fat (cut)?
It depends on your starting point. If you're over ~20% body fat, start with a caloric deficit to improve insulin sensitivity and nutrient partitioning. If you're lean and want to grow, a controlled surplus of 200-400 calories supports muscle gain with minimal fat. Beginners and overweight individuals may achieve body recomposition — building muscle while losing fat simultaneously.
