Diet Calorie Deficit:

A "Diet Calorie Deficit"" refers to the approximate calories you need to reduce from foods (diet) a day for weight loss purposes. When you are in a diet calorie deficit, your body begins drawing upon fat stores for energy, which over time, causes weight loss. Generally, 7,000 kcal = 2 pounds(~1kg). If you are trying to lose 2 pounds per week, you need to create a calorie deficit of 1000 kcal/day over 7 days (1000 kcal deficit a day x 7 days per week = 7,000 kcal deficit per week). To lose 1 pound per week(~0.5kg), you need to create a calorie deficit of 500 kcal/day, or to lose 0.5 pounds per week(~0.25kg), reduce it till 250 kcal/day. Alternatively, you can leave this value as "0" if you do not want to create any calorie deficit from diet (usually for athletes or regular workout people who wants to keep a fit body).
The Diet Calorie Deficit can be adjusted from 0 (no calorie adjustments from food intake) to 1000 calories per day (i.e. the number of calories we want to reduce from food daily).
Important: Generally, women should not consume less than 1,200 calories per day, and men should not consume less than 1,500 calories per day.


Calorie Burning from physical activity depends on intensity, duration, frequency and body weight. 


Intensity settings: 0 = little or no exercise at all (sedentary); 1 = light exercise (e.g. light weight lifting, slow walking ...); 2 = moderate exercise (e.g. slow bicycling, volley, water sports, brisk walk ...); 3 = hard exercise (e.g. aerobic, swimming, tennis, football, jogging ...); 4 = athlete level or very hard exercise (training for marathon, triathlon, fast running ...).
