The amount of calories you eat on the keto diet is different from person to person. It depends on many different factors, including: your age, current weight, metabolic rate, activity level and hormonal effectiveness. It also depends on your end goal – for example how much weight you want to lose or how much lean muscle you want to gain. We have developed a simpleketocalculator to help you determine how many calories you need depending on your personal goals. Simply put your current stats (height, weight and activity level) into theketocalculator together with your goals and preferences to work out exactly what is right for you!
