Nutrition and exercise are BOTH about you and you only. Don't make it about anyone else!
Ever do this?: You're at a luncheon buffet. Your friend decides to have some extra dessert. You think "Well, if they're going to have some, then I guess I will too." Or you think "She's a really healthy person, fit and beautiful, and SHE's eating cheese fries. I guess a few won't hurt me."
I've done this many times. There have been times when, in the back of my mind, I've thought that it was unfair that all my friends were 'splurging' on something extra to eat and I felt that I deserved to have something too. After all, fair's fair, right?
Well, no. It's not that easy. You have NO idea if your friend is a diabetic needing some extra sugar before he passes out on the table. You don't know that SHE ran 10 miles before work this morning and burns off cheese fries like I do excuses for not exercising. I DO deserve to eat, but in a way that's healthy and fits my rules. Splurging is not an option. I'm either fueling my system in a way that fits with my goals or I'm not. Splurging is usually just a situation in which I'm doing something that moves me away from my goals, rather than toward my goals.
I've also been in a lunch situation in which a friend saw me eating an apple and piece of cheese for lunch and said something like "I don't know how you can stay healthy if that's all you're eating for lunch." What she didn't know is that I was getting ready to have a dinner out with my wife and the scales had betrayed me that morning by going a little up instead of a little down.
So, remember: Nutrition and exercise are BOTH about you, and you only. Don't make it about anyone else!
