That said, you can work toward a calorie deficit by eating fewer calories and/or burning more calories through exercise and movement (more on that later). How many calories do you need in a day?
In general, a gradual calorie deficit of 500 to 750 calories a day is considered safe and sustainable for most people, leading to a weight loss of about one to two pounds a week. Kateryna ...
For example, if you typically consume 3,500 calories per day, in order to lose a pound per week, you might shave 500 calories off of your daily caloric intake in order to lower your daily average.
The majority of guidelines agree that a calorie deficit, particularly 500-750 kcal daily, can be recommended to those who want to lose weight. [ 5 ] [ 12 ] A moderate decrease in caloric intake will lead to a slow weight loss, which is often more beneficial than a rapid weight loss for long term weight management. [ 8 ]
Then subtract the number of calories you want to take in per day from this total caloric expenditure. It is usually recommended to choose a caloric deficit between 500 and 1000 calories per day for mild to moderate weight loss. This will achieve an average weight loss of about 0.5 to 1 kg per week.

Calorie restriction (also known as caloric restriction or energy restriction) is a dietary regimen that reduces the energy intake from foods and beverages without incurring malnutrition. [ 1 ] [ 2 ] The possible effect of calorie restriction on body weight management , longevity , and aging-associated diseases has been an active area of research.
So, if you typically eat 2,200 calories a day, on a calorie deficit diet, you should lose weight if you strive to cut that back to 2,000 or so calories a day. There’s a reason why this happens.
However, celery has a thermic effect of around 8%, much less than the 100% or more required for a food to have "negative calories". [5] Diets based on negative-calorie food do not work as advertised but can lead to weight loss because they satisfy hunger by filling the stomach with food that is not calorically dense. [4]
