Start With a Small Deficit, Not the Lowest Number You Can Survive
If you want to lose weight, do not start by slashing calories as hard as possible.
The right calorie target is the one you can stick to long enough to actually lose fat.
For most people, that means eating about 300 to 500 calories below maintenance. That is usually enough to drive steady progress without wrecking your energy, training, or mood.
If you are asking how many calories you should eat to lose weight, here is the short answer:
- estimate your maintenance calories
- subtract 300 to 500 calories
- hold that target for 2 to 3 weeks
- adjust based on your real results
That is what this article is telling you to do.
The Fastest Way to Estimate Your Weight Loss Calories
If you want a practical starting point, use bodyweight.
A decent rough estimate for maintenance is:
- 14 to 16 calories per pound of bodyweight if you are moderately active
- 12 to 14 calories per pound if you are fairly sedentary
- 16 to 18 calories per pound if you are very active
Then subtract 300 to 500 calories.
Examples:
- 150 lb person, moderately active: maintenance is roughly 2,100 to 2,400, so fat loss calories might be 1,700 to 2,100
- 180 lb person, moderately active: maintenance is roughly 2,500 to 2,900, so fat loss calories might be 2,000 to 2,400
- 220 lb person, lightly active: maintenance is roughly 2,600 to 3,000, so fat loss calories might be 2,100 to 2,700
That is a starting point, not a promise. Your body does not read formulas.
A Better Rule: Aim to Lose 0.5% to 1% of Bodyweight Per Week
Most people do best when weight loss is steady, not extreme.
A smart target is losing about 0.5% to 1% of your bodyweight per week.
That means:
- 150 lb person: about 0.75 to 1.5 lb per week
- 200 lb person: about 1 to 2 lb per week
If you are losing much faster than that, calories may be too low. If you are losing nothing for a few weeks, calories may be too high, or your tracking may be sloppy.
This matters because the goal is not just a lower scale number. The goal is losing fat while keeping muscle, energy, and sanity.
Do Not Use the Same Calorie Target for Every Goal
People screw this up because they treat all weight loss the same.
Your calorie target should match your situation.
If You Lift and Want to Keep Muscle
Use the smaller end of the deficit range.
A 300 to 400 calorie deficit is usually smarter than a crash diet. It gives you a better shot at keeping strength and muscle while you cut.
This is especially important for women who want to look leaner and more defined, not just smaller. Muscle is what gives your body shape.
If you train hard, hit protein, and keep the deficit reasonable, you usually look much better at the end of a cut.
If You Are a Beginner With More Weight to Lose
You may be fine with a 400 to 600 calorie deficit if hunger and energy are still manageable.
People with more body fat often have a little more room to diet aggressively at the start. But aggressive does not mean stupid.
If you are exhausted, obsessed with food, and quitting every weekend, the plan is too hard.
If You Are Already Lean
Use a smaller deficit.
The leaner you get, the less room you have for sloppy dieting. Trying to force rapid fat loss when you are already fairly lean is a great way to feel terrible and lose gym performance fast.
The Biggest Mistake: Overestimating Activity and Underestimating Food
This is why calorie targets fail.
People choose a calculator setting that says they are “very active” because they lift four times per week, then they forget to log oils, snacks, drinks, and weekend meals.
Now the target is too high on paper and the intake is even higher in real life.
If progress is not happening, the first fix is usually not a new macro split or a magic supplement. It is honest tracking.
A few rules help a lot:
- log oils, sauces, dressings, and drinks
- weigh calorie-dense foods when possible
- track weekends too
- use the same method every day
- judge the average week, not one random day
If your tracking is bad, your calorie target will look broken even when it is not.
Protein Matters More Than Most People Think
If you want to lose weight without looking flat or weak, eat enough protein.
A good target for most lifters is about 0.7 to 1 gram of protein per pound of bodyweight per day.
That helps with:
- muscle retention
- fullness
- recovery
- better training performance while dieting
If calories are set right but protein is terrible, the cut usually feels worse than it needs to.

How to Adjust Calories When Weight Loss Stalls
Do not panic after three days.
Hold your calorie target for at least 2 weeks, ideally 3, while tracking consistently. Then look at:
- average bodyweight across the week
- gym performance
- hunger and energy
- waist measurements or progress photos if you use them
Then make one small adjustment.
If weight is not dropping and adherence was solid, lower calories by 100 to 200 per day.
If weight is dropping too fast and your training feels awful, add 100 to 150 calories back in.
Small changes win here. Big cuts usually just create rebound eating.
A Simple Starting Point for Most People
If you want the easiest possible framework, use this:
- Estimate maintenance calories.
- Subtract 300 to 500 calories.
- Eat at least 0.7 grams of protein per pound.
- Lift 3 to 5 times per week if you can.
- Track your average weight for 2 to 3 weeks.
- Adjust calories only if the trend says you need to.
That is the boring answer. It is also the answer that works.

What This Article Is Telling You to Do
Set your calories 300 to 500 below maintenance, track them honestly for the next 2 weeks, and adjust based on your weekly weight trend.
If you want that to feel less tedious, Soma lets you track calories and workouts in one place, which makes it easier to see whether your intake is actually helping you lose fat without spinning your wheels.
