Judge foods by the calorie consumption change and not by the bathroom scale.
The body does strange things in changes of body weight, when viewed on a day by day basis. While I support recording daily weight, I feel it is important to ignore the number until enough weeks have passed to properly read a trend in weightloss. It is normal for weight to zig-zag like a stock listing on the stock market.
If one is attempting to evaluate a suspected trigger food, the results on the bathroom scale in the days that immediately follow a food test are primarily a random change and cannot be used to judge the food.
However, in my experience, given a careful recording of foods, and thus calories, in software like the Fitday download, one can see immediate changes in calorie consumption in response to a food being tested. There is no need to wait for the calories to eventually lead to changes in weightloss rate. If the food leads to a higher calorie day, then it is a food that needs to be avoided until goal.
For example, I like almonds. Almonds are a wonderful food for low carbing. Yet, for me personally, almonds seem to not provide short term satiation. On a day I eat almonds, I am likely to have a higher than normal calorie consumption for the day by about as many calories as the almonds were. Thus, I know that I must limit almonds. The same analysis approach can be used for low carb bars, or any food.
In time one can fill the refrigerator with foods known to best satiate.
IMHO: Successful weightloss does not come from willpower. The regulatory forces of the body can break down anyone's willpower. The key is to manipulate the body's regulatory process. Ideally, one would never allow one's self to get hungry, and yet have total calories low enough to lose weight. I have used this approach with success.
