Question: how many calories per day on keto diet to lose weight?
Answer: This leads to a theoretical weight loss of 1 lb per week (3500 kcal per pound of fat). If you ate 1300 calories on keto and lost 2 lbs in a week, you'd have to use 1000 calories from fat stores. That means that 1000 calories of expended energy are external of your diet a day, for 7 days.
