Actually, weighing yourself daily may help with weight loss.
I have heard many people claim that weighing yourself daily will hurt your ability to lose weight. It makes sense that your body weight due to hydration and fiber intake can fluctuate quite a bit every day. These fluctuations can create the appearance of weight gain and therefore, it is believed that a person trying to lose weight will become discouraged when seeing his or her weight go in the direction opposite to their efforts. Because of this concept, many professionals have wrongly suggested that daily weighing can hinder weight loss and thus recommend against it.
Personally, I could not disagree more and highly recommend daily weighing. I have found that
it helps me with behavior modification. If I eat certain foods and gain weight, I tend to avoid them from there on out. For example, popcorn tends to cause false weight gain due to the fiber and salt content. If I eat a bag of microwave popcorn, I gain 1-2 pounds and it tends to constipate me. It is a source of empty calories so avoiding it makes sense.
There is plenty of research to support the efficacy of daily self-weighing to assist with weight loss success. I found no fewer than five in a quick search,,,,. In fact, one study showed that weighing oneself twice a day was useful in assisting weight loss through behavior modification. The key to success in all of these studies is daily or twice daily weighing with a realistic target.
The bottom line: Daily weighing with a realistic target and an understanding that fluctuations are normal will lead to the most successful weight loss.
