You don't have to weigh yourself every day. Some people get discouraged when they see day-to-day fluctuations, and prefer to weigh once a week. That's OK with Diet Power. In fact, the program won't mind if you weigh only once a month.
The only drawback to infrequent weighing is that Diet Power will take a lot longer to learn your true metabolic rate and to adjust your calorie budget accordingly. The more often you weigh in, the more precisely the program will direct you toward your goal.
If you don't want to weigh daily, just click the OK button when prompted for your weight, and Diet Power will assume it's the same as before. Any error that this introduces will be corrected next time you log your true weight.
If you do weigh daily and your scales are not accurate to at least a quarter of a pound, consider replacing them. In a good weight-control program, progress is measured in ounces per day. Being able to see this difference can help your morale tremendously. Click here for tips on buying scales.
Always weigh yourself at about the same hour of the day. The best time is first thing in the morning, right after you go to the bathroom, because the temporary gain from an unusually heavy meal or a large intake of fluids will have largely worn off by then.
Your best bet is to weigh in the buff, since the weight of your clothes will vary. If you can't, then subtract about two pounds from your weight in indoor clothing¾three pounds if you're wearing shoes.
