Weight Trends - Your Key to Success

Your "Weight Trend" is one of the most important pieces of information provided by WeightWare. It averages out the daily ups and downs of your weigh-ins, and shows your true weight trend over a specific time period. This provides valuable feedback on how your diet and exercise strategies are affecting your weight.

In WeightWare, your Weight Trend is displayed as two numbers. First, is the average weekly weight change. Next is the average daily energy deficit (or surplus). These are important numbers for you to use when making decisions about your weight loss program. 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 still result in substantial weight loss when applied over longer time periods (and, they are easier to achieve!). The table below shows how much weight you will lose with small daily calorie 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)

Note: your Weight Trend in WeightWare is calculated using a statistical technique called "least squares linear regression". This is the same technique used in stock market analysis, to help see the underlying patterns in stock prices that changes from day to day.

In the graphs shown below, the Weight Trend is shown as a red line in the graph, and the actual numbers are displayed at the top of the graph. Please note the differences in the two trends. Both graphs end on the same date, the starting dates are different. Because the time frames are different, the trend numbers are different. In general, your recent trend is most important, as it indicates how your weight has changed over the recent past.

The graph above shows a slower rate of weight loss than the graph below. The upper graph is for a longer period of time, so this means that weight loss has been faster in the recent past.
