Last night on the Biggest Loser, the number on the scale was discussed a few times. One contestant had only lost 2 pounds at home during her 30 days and she made the excuse that she felt stronger and lost inches. The trainers were not buying that excuse. The numbers don't lie, they said. Later in the show when another contestant lost 0 for the week, they again stated: the numbers don't lie. This contestants excuse was working out harder and with more intensity.
During the losing mode, the numbers definitely are important. You work hard, you eat right, you lose weight. Don't exercise, eat mindlessly, eat don't lose weight!
Now, that I'm into the maintaining mode, the numbers are still somewhat important, but it is all the extra intangibles such as gaining muscle, losing inches, etc. that need to enter the equation.
The numbers don't lie...another reason I dug that scale out and will continue to monitor myself daily.
