Weight loss calculator

Weight loss calculatorThe weight loss calculator allows you to estimate your weekly and monthly weight loss. Just enter your daily energy expenditure and the caloric content of your diet.

Instructions:
1. Enter your daily energy expenditure. You can use this calculator to get the value.
2. Set the "Daily intake" dial at the value you plan to aim for in your diet.
3. If the evaluation says you weight loss will be "High" or "Extreme" you should reconsider your plan.

Background:

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. First of all one assumption is that all your weight loss is fat. In the beginning of a diet most people will typically also lose body water and the weight loss will therefore initially be higher.

If the daily caloric deficit is too high (i.e. >1.000 kcal/ day), most people will typically also lose muscle mass. In short term this will increase the weight loss, but in the long run this will be an unwise strategy as your resting metabolic rate and your physical capacity goes down, which will make it more difficult to maintain the weight loss.

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.

All excess energy is stored as fat. And glycogen, but that's just quick access energy. Most is stored as fat no matter if it came from fat, protein or carb. Not just actual fat. Fat reserves are from eating more than you burn, of everything. Not just of fat...

I have studied nutrition and weight loss for over ten years now, and I passionately believe a weight loss calculator and calorie controlled diet is the hard way to lose weight. Is there an easier way? Yes, there is. If you are overweight or obese, the only way you could get that way is by eating the wrong foods. When you know what those foods are and avoid them, your fat will simply melt away all by itself with little effort.




Not to be rude, but if you've studied nutrition for that long and still think it's about eating the wrong foods, if ask for your money back from whatever higher learning institution to went to.

I agree with this. Once all the heavy fat foods are stopped, the weight should definitly go away.

Well, nice calculator, but that whole "calories in, calories" out or "energy balance" hypothesis a load of bologna. Check out the work of Sam Feltham and go educate yourself about real food, paleo and low-carb nutrition:

This calculator isn't exactly 100% accurate. This calculator is a guesstimate, and everybody's body will lose fat different, you could lose 1/2 every week or even two. However, Decreasing daily calorie intake should be done with exercise to increase the fat lost will making sure you don't have flabby skin.
