BUY A DIGITAL SCALE
This seems easy enough. I recommend that before starting a diet, buy a scale that is accurate to .2 (two-hundredths of a pound). I will explain why below. I also recommend either buying a scale that can record your daily weight, or manually logging your weight everyday. I bought a scale that was accurate to .2 and logged my weight at Sam's Club for $22. It has been a great investment.
WEIGH YOURSELF EVERYDAY
You'll find that almost every other dieter will tell you to weigh yourself only once a week. I recommend the exact opposite. I am very goal oriented and I like to see results everyday. The reason I recommend buying a scale that is accurate to the .2 is that there is a very big difference between weighting 170.8 one day and 170.0 the next day. Losing .8 pounds in one day is excellent. However, if your scale is not accurate enough to report the loss and still shows 170 after a day of healthy eating and working out, you will feel extremely discouraged. A more detailed scale makes it easier to keep a positive outlook. The more successes (days with positive weight loss) the easier it is.
MAKE YOUR DIET PUBLIC
Tell people you're on a diet. There's no reason to be ashamed to be on a diet. I found that trying to keep my diet a secret was harder than just telling people. In fact, telling your coworkers, girlfriend, family, etc. will increase your accountability. It motivated me knowing that my coworkers and family knew that I was dieting because I did not want to fail. I also chose a typical "fat picture" and put it on my fridge, in my cubicle, and on my wall. I wanted to have a continual reminder to lose the weight. I know it's a cliche, but it was important for me to remind myself of my ultimate goal.
FIND YOUR EMOTIONAL REASION FOR STAYING ON TRACK
Researchers at George Washington University discovered that people who successfully transform their bodies are set in action by some sort of "emotional trigger" that helps to clarify their reasons for deciding to make change. In the study, researchers found that any event which elicited strong emotions such as alarm, embarrassment, shame and/or fear actually inspired people to transform their bodies for the better.
COMPETITION
Take our diet pills with a friend or family member. Have a contest to see who can lose the most weight in the shortest period of time. Competition brings out the best in people.
