Internal Medicine

Recommended daily calorie intake depends on age, sex, activity level, and overall health goals. On average, women need 1,600–2,400 calories per day, while men typically require 2,000–3,000 calories per day. Sedentary adults fall at the lower end of these ranges, while highly active individuals need more to maintain energy balance.

If you're experiencing unexplained weight changes, fatigue, or appetite shifts, calorie needs alone may not tell the full story. Underlying conditions—like thyroid imbalances, diabetes, or nutrient deficiencies—can affect how your body uses energy. Take a free, instant, online symptom check to better understand what may be going on and get personalized guidance on your next steps.
