The Weight Loss calculator gives you an idea of how long it will take to reach your weight loss goal. After you enter your info, the calculator estimates how many calories you need to stay at the same weight (total daily calorie needs).
1. Enter your current weight, height, age, and activity level, your start date for losing weight and the number of pounds (or kilos) you want to lose, as well as a caloric deficit option.
2. Click “Calculate.”
3. You will get your daily calorie goal and the target date to reach your weight loss goal.
Short term weight loss is primarily determined by the difference between caloric intake and caloric expenditure. As one lb of human body fat has a caloric content of approx. 3.400 kcal the average weight loss in fat can be reasonably estimated.This calculation is however based on certain assumptions.
For a healthy weight loss, you should generally aim for a daily caloric deficit between 300 and 1.000 kcal. Some of this deficit should ideally come from an increase in physical activity
