How do I calculate how many calories I need to lose weight?▾
Start with the TDEE calculator to find your maintenance calories, then create a deficit of 500-750 calories per day for safe weight loss of 1-1.5 pounds per week. Use the calorie calculator to set your daily target.
Should I track macros or just calories?▾
Tracking macros (protein, carbs, fat) ensures you maintain muscle while losing fat. Use the macro calculator to find your ideal split based on your goals and preferred diet style.
What is the best tool for intermittent fasting?▾
Our intermittent fasting calculator helps you plan eating windows for 16:8, 18:6, 20:4, and OMAD protocols. Combined with the calorie calculator, you can ensure you meet your nutrition goals within your eating window.
