Daily Energy Deficit
-
Key to Successful Weight Loss

Losing weight is all about Calories In vs. Calories Out. To lose weight, you need to consume a few less calories each day than your body burns. You can do this by eating a little less, exercising a little more, or (ideally) a little of both.

Slow and Steady

For successful long-term weight loss, most studies recommend losing weight slowly. A rate of 0.5-1 lb (0.2-0.4 kg) per week is best, but even slower rates can result in substantial weight loss when applied over time (and, they are easier to achieve!). The table below shows how much weight you will lose with small daily energy deficits.

Expected Weight Loss
Daily Energy Deficit per Week per Month per Year
100 calories (420 joules) 0.2 lbs (0.1 kg) 0.9 lbs (0.4 kg) 10.4 lbs (4.7 kg)
200 calories (840 joules) 0.4 lbs (0.2 kg) 1.7 lbs (0.8 kg) 20.9 lbs (9.5 kg)
300 calories (1260 joules) 0.6 lbs (0.3 kg) 2.6 lbs (1.2 kg) 31.3 lbs (14.2 kg)
400 calories (1670 joules) 0.8 lbs (0.4 kg) 3.5 lbs (1.6 kg) 41.7 lbs (18.9 kg)
500 calories (2090 joules) 1.0 lbs (0.5 kg) 4.3 lbs (2.0 kg) 52.1 lbs (23.7 kg)

The problem with this approach is knowing whether or not you are on track. Your weight changes all the time, and day-to-day changes of 2-4 lbs (1-2 kg) are fairly common, even if you are successfully losing weight. It's easy to get discouraged when your weight goes up by a pound or two, or to think you are doing very well when it drops by the same amount. But, for weigh loss success it's the long term trend that is important, not the daily weight.

The WeightWare Approach

This is where WeightWare can help. Every time you record your weight in WeightWare, you are providing it with a "data point". WeightWare takes these data points and analyzes them using advanced statistical techniques.* This analysis will show you instantly how your weight loss program is doing, and can help you to stay on track. WeightWare makes this quick and convenient - all you have to do is weigh yourself and record it in WeightWare!

With the Graphs and other tools in WeightWare, you can instantly see what your true daily calorie deficit has been, and how it is changing. This makes it easy to keep your weight loss program on track, and reach your goals.

Compared to calorie counting programs, the WeightWare approach is much easier and quicker (it takes less than two minutes per day). And, because it's based on your actual weight history, the WeightWare approach is more accurate too! Each time you record your weight in WeightWare, your weigh records will be instantly analzyed, and your "daily energy balance" will be calculated (see the example below). This critical information lets you start each day armed with the information you need to modify your diet and exercise programs to stay on track for weight loss success.
