Weighing yourself weekly is a great feedback. If you have expanded your diet, this can be the early warning system. If you have gained 1/2 to 1 pound in a month, this means that something you are doing is not adding up. This means you have added at least 60 calories a day somewhere. A half-pound a month becomes six pounds in a year, which becomes 30 pounds in five years—easy to put on, harder to take off—and a lot easier to catch early and deal with.

The power of small numbers can work in your favor or against you

If you have had consistent increases in your weight, then it is time to begin to write down everything again and make a further commitment to walking. Movie stars can gain 40 pounds for a part quickly. But to lose it requires hours in the gym for weeks. Before the weight creeps up on you, start checking what you are doing. Keep a food diary, and keep an activity roster.

Examples of the power of small numbers in losing weight:

Walking a mile a day in 17 minutes uses 100 calories—in a year that is ten pounds lost!

However: A pat of butter is 46 calories—one pat a day is 5 pounds in a year.

One beer a day is 100 calories—at the end of a year that is a gain of ten pounds
