Low carb and calorie restricted diet

A calorie is a unit of energy your body uses to perform hundreds of tasks. These include voluntary movements like walking, running, and jumping, as well as involuntary ones like breathing, circulating blood throughout your system, and maintaining normal body temperature. Your body needs a certain number of calories just to keep those involuntary processes going. This is referred to as your basal metabolic rate, or BMR. Your BMR is influenced by many factors, including your age, gender, body composition, and genetics. Overall, the more active you are, the more calories you need. However, the calories in most foods are a combination of carbs, protein, and fat. For instance, although eggs are considered a protein food, the majority of their calories actually come from fat.

Although the inaccuracy of dietary records for obese individuals is well documented 31, 32, it seems unlikely that a systematic discrepancy of this magnitude occurred between groups of subjects who were comparably overweight.
