A low-calorie, low-carb, low-fat diet generally means eating below average amounts of energy, carbohydrates, and fats while still meeting basic nutrition needs. Here’s a clear, simple breakdown

1. Low-Calorie Diet

Usually:

 1,200–1,500 kcal/day (for most females)

 1,500–1,800 kcal/day (for most males)

Anything below your daily energy needs but not below 1,200 kcal for teens or adults unless supervised by a healthcare professional.
