Losing weight basically comes down to 1 factor: By burning extra energy than you’re consuming, a math answer referred to as a calorie deficit.
You can create a calorie deficit by lowering your calorie consumption or combining fewer energy with extra train. But even with that, you could possibly nonetheless have a tough time dropping pounds. (It’s by no means simple, proper?)
To demystify the method and clarify doable dangers, we flip to registered dietitian Beth Czerwony, RD.
What is a calorie deficit?
A calorie deficit merely means you’re consuming fewer energy than you’re burning. People use calorie deficit to reduce weight and preserve weight reduction.
“If you want to lose weight with a calorie deficit, I suggest tracking what you’re currently eating before making any changes,” says Czerwony. “It’s good to understand your starting point.”
Use a meals diary app to file what you eat and what number of energy you devour over per week or two. (An app is a really handy option to observe consuming habits.) Then, you should utilize a calorie deficit calculator to determine your day by day calorie goal to satisfy your purpose.
How to calculate calorie deficit
First, you could know your day by day calorie requirement. Czerwony prefers the Mifflin-Saint Jeor formula for calculating your day by day calorie wants.
“There are other tools, but the Mifflin-Saint Jeor formula considers your height, weight, sex, age and activity level — which makes it less generic than other calorie calculators,” notes Czerwony.
Once your day by day calorie requirement, subtract your calorie deficit purpose from that quantity. For instance, in case your day by day calorie want is 1,800 energy and also you desire a 500-calorie deficit, your new day by day calorie goal is 1,300 energy (1,800 – 500 = 1,300).
Or you could find a calorie deficit calculator on-line that does each of those steps collectively.
What is a protected calorie deficit?
A day by day 500-calorie deficit ought to assist you to lose a few pound per week — and probably even a bit extra, says Czerwony. “Eating 500 fewer calories per day is a good place to start,” she provides.
She says another choice is to do a smaller calorie deficit — 200 or 300 energy a day — mixed with rising your day by day train.
Losing one pound per week might not sound like lots, however slower weight reduction is extra more likely to stick in the long run. And it’s simpler in your physique to regulate to a smaller calorie deficit than a bigger one.
If you begin with too large of a calorie deficit, you’re more likely to have some disagreeable negative effects, comparable to:
Even with a 500-calorie deficit, it could possibly take your physique time to regulate. You might not lose any weight for the primary week or two.
“If you do lose weight in the first week, you’re probably dropping water weight,” explains Czerwony. “This is usually due to cutting some of the junkier carbs and salt from your diet.” After that, the fats loss begins.
What are the risks of calorie deficit?
If you might have any current well being situations, a calorie deficit can probably trigger issues. “You can harm yourself with a calorie-deficit diet,” warns Czerwony. Here’s what to know when you have:

Don’t reduce an excessive amount of protein (it’s unhealthy in your muscular tissues)
Cutting an excessive amount of protein out of your weight loss plan could make it troublesome in your physique to keep up muscle. And in case you reduce too drastically in your meals consumption, particularly protein, your physique will break down muscle for gasoline. “Your body does this first before turning to fat for fuel,” says Czerwony.
Muscle mass performs an necessary position in conserving your metabolism powered up, so shedding muscle is doubly unhealthy in case you’re making an attempt to reduce weight. Your metabolism helps your physique course of meals into power. A gradual metabolism burns energy slower, which implies energy get saved as fats.
“You have to go into calorie deficit just enough to get your body to use fat stores but not go into starvation mode where you start burning muscle mass,” states Czerwony.
Keeping the protein and dropping the sugary carbs will help you hit this candy spot.
People typically ask in case you can nonetheless construct muscle whereas in a calorie deficit. The reply? Yes, you may construct muscle mass on the weight loss plan.
But you could protein-rich meals and the correct quantity of energy to provide the power to train and to maintain your physique from burning muscle. A dietitian will help you discover the suitable steadiness of meals.
Don’t reduce too many energy (it results in the dreaded yo-yo)
If you leap into an enormous calorie deficit proper off the bat, you run the danger of bouncing backwards and forwards between undereating and overeating.
“You might start out fine on a large calorie deficit,” says Czerwony. “But at some point, you may get overly hungry and eat too much. Then you overcompensate and restrict your food intake. Then you overeat again, and you end up yo-yoing.”
Over time, so-called yo-yo weight-reduction plan may very well result in extra weight achieve. It’s higher to chop out a smaller quantity of energy at first so that you don’t get too hungry.
Why aren’t you dropping pounds on a calorie deficit?
It appears logical that in case you’re consuming fewer energy than you’re burning, it is best to reduce weight simply. But a number of components may be stopping your weight reduction, says Czerwony.
These components affect your metabolism, and embody:
- Medications: Many medicines both promote weight achieve or make it troublesome to lose kilos. Examples embody some hormonal contraception medicines, antidepressants, anti-psychotics and insulin for diabetes.
- Poor sleep: If you’re not sleeping effectively, your cortisol ranges are in all probability not optimum, affecting your metabolism.

She says it’s good to start out with some fundamental blood assessments, particularly if it’s been a few years or extra because you’ve had them. And if medicines are getting in the best way of your weight reduction, your healthcare supplier can discuss to you about doable options to strive.
