How Many Calories Should You Eat While Cutting

Cutting season brings a lot of confusion. Walk into any gym and ask five different people how many calories you should eat while cutting, and there’s a good chance you’ll get five different answers. Some will say eat as little as possible. Others will say track macros religiously.

The truth is that cutting calories the right way is part science and part personal experimentation, and getting it right can mean the difference between losing fat while keeping hard earned muscle, or losing both muscle and motivation.

This article breaks down exactly how many calories a person should eat while cutting, how to calculate that number, and what factors can change it along the way.

What Does “Cutting” Actually Mean

In bodybuilding and fitness circles, cutting refers to a phase where someone intentionally eats fewer calories than their body burns in order to lose body fat while trying to preserve as much muscle mass as possible. It usually follows a bulking phase, where the goal was to build muscle and often gain some fat along with it.

The idea behind cutting is simple on paper. Eat less, move more, and the body will start using stored fat for energy. In practice, it takes more nuance than just eating less food. Cutting too aggressively can lead to muscle loss, fatigue, hormonal issues, and a slower metabolism. Cutting too gently might not produce visible results fast enough, which can be discouraging.

Why Calories Matter More Than Anything Else

Every diet trend, meal plan, or fitness influencer will have an opinion on the best approach to cutting. But at the foundation of every successful cut is one simple principle: calories in versus calories out.

The body needs a certain number of calories just to function, this is called maintenance calories or Total Daily Energy Expenditure (TDEE). To lose fat, a person needs to eat below that number consistently, creating what is known as a calorie deficit.

While things like protein intake, workout timing, and food quality all play a role in how a person looks and feels during a cut, none of it matters if total calorie intake is not in a deficit. This is why understanding calories is the first and most important step.

Step One: Calculate Maintenance Calories

Before figuring out how many calories to eat while cutting, it’s necessary to know how many calories the body burns in a day just to maintain its current weight. This is the TDEE.

There are several ways to estimate this number.

Using an Online TDEE Calculator

The simplest method is to use a free online calculator. These typically ask for:

• Age
• Gender
• Height
• Weight
• Activity level
• Sometimes body fat percentage

These calculators use formulas like the Mifflin-St Jeor equation or the Katch-McArdle formula to estimate Basal Metabolic Rate (BMR), then multiply it by an activity factor to get TDEE.

Using the Mifflin-St Jeor Formula Manually

For those who want to calculate it by hand, here is the formula:

• For men: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age) + 5
• For women: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age) – 161

Once BMR is calculated, it gets multiplied by an activity multiplier:

Activity Level	Description	Multiplier
Sedentary	Little to no exercise	1.2
Lightly active	Light exercise 1-3 days a week	1.375
Moderately active	Moderate exercise 3-5 days a week	1.55
Very active	Hard exercise 6-7 days a week	1.725
Extremely active	Physical job or twice daily training	1.9

This final number is a rough estimate of maintenance calories, or the amount needed to stay at current weight.

Step Two: Create the Right Deficit

Once maintenance calories are known, the next step is subtracting from that number to create a deficit. This is where a lot of people make mistakes, either going too extreme or not aggressive enough.

Moderate Deficit (Recommended for Most People)

A deficit of about 15 to 20 percent below maintenance is generally considered the sweet spot for most people who lift weights and want to preserve muscle. For someone with a maintenance of 2,500 calories, this would mean eating somewhere between 2,000 and 2,125 calories per day.

This moderate approach tends to lead to:

• Steady fat loss without extreme hunger
• Better muscle retention
• More sustainable energy for workouts
• Less risk of metabolic slowdown

Aggressive Deficit

Some people, especially those with more body fat to lose, may choose a larger deficit of 25 percent or more. This can speed up fat loss but comes with tradeoffs like increased hunger, fatigue, and a higher risk of losing muscle if protein intake and training are not dialed in.

Conservative Deficit

A smaller deficit of around 10 percent is sometimes used by lean individuals trying to hold onto every bit of muscle possible, often called a “lean gains” style cut. This method is slower but tends to feel easier day to day.

How Many Calories Should You Actually Eat

To put real numbers to this, here is a general guide based on common body weights and moderate activity levels. These are estimates and should be adjusted based on individual results.

Body Weight	Estimated Maintenance Calories	Moderate Cutting Calories (15-20% deficit)
130 lbs	1,800 – 2,000	1,500 – 1,700
150 lbs	2,000 – 2,200	1,650 – 1,850
180 lbs	2,400 – 2,600	2,000 – 2,200
200 lbs	2,600 – 2,900	2,150 – 2,400
220 lbs	2,900 – 3,200	2,400 – 2,650

These numbers assume moderate activity levels, including regular strength training. Someone who is more sedentary outside of the gym will land on the lower end, while someone with a physically demanding job or high daily activity will land higher.

Protein Intake Matters Just as Much

While the focus of this article is on total calories, it would be incomplete without mentioning protein. During a cut, protein becomes even more important than usual because it helps preserve muscle mass while in a calorie deficit.

Most fitness professionals recommend somewhere between 0.7 and 1 gram of protein per pound of body weight during a cut. Someone weighing 180 pounds might aim for 130 to 180 grams of protein per day, spread across meals.

Prioritizing protein also helps with hunger management, since protein is more filling than carbs or fat calorie for calorie.

Signs the Calorie Target Needs Adjusting

Cutting calories is not a “set it and forget it” process. The body adapts over time, and what worked in week one might not work in week six. Here are signs that calorie intake may need to be adjusted.

Weight Loss Has Stalled

If the scale hasn’t moved in two to three weeks despite consistent tracking and effort, it may be time to slightly reduce calories or increase activity.

Fatigue and Poor Performance in the Gym

Feeling constantly drained, weak during lifts, or unable to recover between sessions can be a sign the deficit is too aggressive.

Excessive Hunger or Irritability

Some hunger is normal during a cut, but constant, intense hunger and mood swings may mean the deficit needs to be less extreme.

Losing Strength Rapidly

A small amount of strength loss during a cut is expected, but rapid strength loss across multiple lifts can indicate muscle loss, which usually means the deficit is too large or protein intake is too low.

How Long Should a Cut Last

Cutting calories for too long can backfire. Long-term dieting can lead to metabolic adaptation, where the body becomes more efficient at conserving energy, making further fat loss harder.

Most successful cuts last somewhere between 8 and 16 weeks, depending on how much fat needs to be lost. Trying to cut for months on end without a break often leads to burnout, both mentally and physically.

Some people choose to incorporate diet breaks, short periods of eating at maintenance calories every few weeks, to help with adherence and hormone regulation before continuing the cut.

Should Calories Be the Same Every Day

Not necessarily. Some people prefer a flat daily calorie target, eating the same amount every day of the week. Others prefer calorie cycling, eating more on training days and less on rest days.

Flat Daily Calories

This is the simplest approach and works well for beginners or anyone who prefers consistency and simplicity in their meal planning.

Calorie Cycling

This approach shifts more calories, particularly carbohydrates, to training days to fuel performance, while slightly reducing calories on rest days. The weekly total still needs to match the intended deficit, but daily intake fluctuates.

Both methods can work. The best one is whichever a person can stick to consistently.

Common Mistakes People Make While Cutting

Even with the right calorie target, certain habits can sabotage progress.

• Not tracking food accurately, guessing portions instead of measuring
• Drinking calories through juices, alcohol, or sugary drinks without accounting for them
• Cutting calories too fast, leading to muscle loss and burnout
• Ignoring protein intake while focusing only on total calories
• Not adjusting the target as weight drops and maintenance calories decrease
• Overestimating calories burned through exercise

Being aware of these pitfalls can help someone stay on track and avoid unnecessary frustration.

Tracking Progress Beyond the Scale

The scale is useful, but it’s not the only tool that matters during a cut. Body weight can fluctuate daily due to water retention, sodium intake, hormones, and digestion.

Other useful tracking methods include:

• Progress photos taken every one to two weeks in similar lighting and poses
• Body measurements around the waist, hips, chest, and arms
• How clothes fit over time
• Strength levels in the gym
• Progress photos combined with weekly average weight rather than daily weight

Using multiple data points gives a clearer picture of actual fat loss progress compared to relying on the scale alone.

Final Thoughts

Figuring out how many calories to eat while cutting doesn’t have to be complicated once the basic principles are understood. Start by calculating maintenance calories, apply a moderate deficit of 15 to 20 percent, prioritize protein intake, and adjust based on real world results rather than guesswork.

Cutting is not about starving the body or making drastic changes overnight. It’s about creating a sustainable deficit that allows fat loss while protecting muscle, energy levels, and mental wellbeing along the way. With consistency, patience, and a willingness to adjust when needed, reaching a leaner physique becomes a realistic and achievable goal.
