Do you know one of the worst things for you and your diet? It's all-or-none thinking.
Totally on a diet or totally off a diet
Being totally good or being totally bad
Totally good foods or totally bad foods
Being totally perfect or being a total cheater
Totally starving or totally stuffing
Total success or total failure
The world isn't black and white, and neither are you.
Each of these opposites has gradations. For example, you can be on your diet but go off it from time to time. Still, you can consider yourself on a diet. Remember that change is often two steps forward one step back. You can think of a few weight gains as acceptable while dieting. Also, weight loss success doesn’t come all at once at the end.. You can count up the smaller successes and be triumphant even before you reach your ultimate goal.
All-or-none thinking is most definitely a dieter's enemy.
