Question: how many calories should i eat to lose half a kilo a week?
Answer: Well, to lose roughly half a kilo a week (a healthy goal) you need a 500-calorie-per-day deficit, he explains. In other words, just delete 500 calories from the number you found above. But a calorie deficit doesn't have to (and, in reality, shouldn't) come solely from eating less, says Valdez. Exercise can help, too.
