Plan you menus. How many calories, protein, carbohydrates, and fats do you need for each day?
Then promise yourself you will not eat a treat/cheat off of your plan until and unless you have eaten all the nutrients for that day.
Just as you need fuel to drive your car, feed yourself healthy foods before you choose any extra calories.
Remember, in some cases WATER can quench both thirst AND hunger.
Congratulate yourself for each day you eat on plan!
Multivitamins can be useful in your nutrition goals, but do not count them as "food."
Eat from the rainbow - a variety of foods and colors will increase the nutrients you get, and this can improve your health!
Get what you need each day before any splurges.
It's a way of honoring your temple.
