Who is an 1800 calorie diet for?

An intake of 1800 calories per day represents a moderate deficit for most men and some very active women. For a sedentary man with a TDEE of 2200 kcal, this represents a deficit of 400 kcal (loss of about 0.9 lbs/week). For an active man at 2700 kcal, the deficit reaches 900 kcal.

Macronutrient distribution

At 1800 calories, a balanced distribution would be: 135g protein (30%), 180g carbs (40%), 60g fat (30%). This distribution promotes muscle preservation and provides the energy needed for daily activities.

Advantages of this calorie level

1800 calories allows for a varied and satisfying diet. You can include starches at each meal, snacks, and even occasional treats. It's a level that doesn't create excessive frustration and is sustainable long-term.

Meal structure

Suggested distribution: breakfast 400 kcal, lunch 550 kcal, dinner 550 kcal, snacks 300 kcal. This structure offers flexibility while maintaining a consistent deficit.

Important

Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Too aggressive a deficit can be dangerous for your health and counterproductive for weight loss.
