Nutrition Tools
Free calculators to help you plan your daily nutrition — water, protein, carbs, and fat.
Why Nutrition Tracking Helps
You do not need to count every gram forever. But understanding roughly how much water you need and how your calories split between protein, carbs, and fat gives you a clear starting point. Small consistent adjustments beat drastic changes every time.
Macronutrients Basics
- Protein: builds and repairs muscle, keeps you full. Roughly 4 kcal per gram.
- Carbohydrates: primary fuel for exercise and brain. Roughly 4 kcal per gram.
- Fat: hormones, cell health, long-lasting energy. Roughly 9 kcal per gram.
Hydration Basics
Water needs vary by body size, activity, climate, and diet. A common starting estimate is 30–35 ml per kg of body weight per day, plus extra on hot days or after exercise. Our Water Intake Calculator adjusts for these factors.
Frequently Asked Questions
Do I need to track macros forever?
No. Use the calculator to find a baseline, follow it for a few weeks, then adjust based on how you feel and perform. Many people stop tracking once they get a feel for portions.
Is keto / low-carb / high-protein right for me?
That depends on your goals, health, and preferences. The macro calculator lets you try any split. Speak with a dietitian if you have a medical condition.
Do these tools replace a dietitian?
No. They are educational estimates. A registered dietitian can give personalized advice based on your full health picture.
