Frequently Asked Questions

What is TDEE?

TDEE stands for Total Daily Energy Expenditure — the total number of calories your body burns in a day. It includes your Basal Metabolic Rate (the energy used at rest), the thermic effect of food (digestion), and all physical activity including structured exercise and daily movement.

How is TDEE different from BMR?

BMR (Basal Metabolic Rate) is the calories burned at complete rest — just to keep organs functioning. TDEE multiplies BMR by an activity factor to account for everything you do during the day. BMR is always lower than TDEE; for a lightly active person, TDEE is typically 1.4–1.5x their BMR.

How much water should I drink per day?

A general rule is half your body weight in ounces. So a 160 lb person should drink about 80 oz (10 cups). Active people and those in hot climates need more.

Does coffee count toward water intake?

Yes, moderate coffee and tea consumption counts toward hydration. While caffeine is a mild diuretic, the fluid in these beverages still provides net hydration.
