It takes your gender, height, current weight, desired weight and calculates the calorie needed by the body every day. Based on the calculated calorie, protein, carbohydrate and fat quantities are calculated.

• Carbohydrate intake should be a minimum of 45% (945 calories) and a maximum of 65% (1,365 calories). I.e. between 236 and 341 grams of carbohydrates / day
• Protein intake should be a minimum of 10% (210 calories) and a maximum of 35% (735 calories). I.e. between 53 and 184 grams of protein / day
• Fat intake should be a minimum of 25% (420 calories) and a maximum of 35% (735 calories). I.e. between 47 and 82 grams of protein / day

Make sure your food intake should have a balanced quantities of carbs, protein and fat. If you try to completely avoid any of the nutrients, the metabolism will be affected
