Calorie Deficit 101: A Beginner's Guide to Weight Loss

A calorie deficit simply means consuming fewer calories than your body burns. Done sustainably, it's the foundation of healthy weight loss.

First, estimate your maintenance calories, then reduce by a modest amount—usually 300–500 calories per day—so you lose weight without feeling deprived.

Macros still matter. Prioritize protein to preserve muscle, include fiber-rich carbs for energy, and don't fear healthy fats.

Use CalorieScan to log meals quickly and stay honest about portions. Consistency over weeks matters more than a perfect day.

If progress stalls, reassess sleep, stress, and activity before cutting calories further. Sustainable deficits win every time.
