How Many Calories Should You Eat to Lose Fat?

Most people pick a calorie target by feel, then wonder why the scale won't move. The math is actually simple. This is the same formula I use with one on one clients before we touch a training plan.

1. Find your maintenance, don't guess it

Maintenance is the calorie level where your weight holds steady for two weeks. Skip the online TDEE calculators for a second. Eat what you normally eat, weigh in every morning, and average the week. If the average is flat, that's your real maintenance. If it's drifting up or down, adjust by 150 calories and repeat.

2. Set the deficit by goal, not by panic

For most people I coach, a 20 to 25 percent deficit hits the sweet spot. Big enough to see the scale move week to week. Small enough that you can still train hard, sleep, and hold onto muscle. Aggressive crash diets work for two weeks and then break you. Don't be the person who restarts every Monday.

3. Protein first. Always.

Set protein at 0.8 to 1g per pound of bodyweight before you touch carbs and fats. This is what protects your muscle when calories are low. Without enough protein, your deficit will burn through lean tissue and you'll end up smaller but softer, not leaner.

4. Track for two weeks. Adjust on data, not feelings.

After two weeks at your new number, look at the trend. Lost 1 to 2 pounds? Hold. Lost more than that? Eat 100 calories more so you don't tank your metabolism. Lost nothing? Cut 150 to 200. Repeat the cycle every two weeks until you hit your goal.

5. The honest part nobody says

Calorie math works on paper. The real fight is consistency. Travel, weekends, bad days. That's where having a coach or a structured program matters more than the exact number. The plan you actually follow beats the perfect plan you don't.
