How long can you last with such strict rules?
Sure it may be easy for the first week, maybe month but no one can live their entire lives with such strict rules without going crazy or binging. When a food is put "off limits" such as carbohydrates or sweets, it make me want it more! It's all I think about, and the fact that I'm not "allowed" to eat this cookie/chocolate/peanut butter/name your food choice, it makes me that much more likely to binge.
Boundaries and guidelines, I think, are much more useful tools and ways to live a healthy life style. Everyone wants to be healthy and wants to WANT to choose the watermelon over the chocolate cake but sometimes we need a little lienancy and variety in our diets to truly appreciate food and the flavors it has to offer. When I deny myself something I've been craving for so long, I tend to go overboard and end up binging, hating myself, and feeling like crap! It's the "Oh well, I've already screwed up so why not go overbaord." all or nothing type of attitude which is very harmful.
Boundaries should be positive. They should provide you with guidelines to live by, but not burden you with rules and restriction. No one food with make or break your eating habits. No one food will make you fat. As long as you stay in your daily caloric boundaries, you will be fine and feel much less deprived. Beause you're eating the foods you want, you don't have to feel guilty about it, and it will not make you fat!
Do Not Worry
"Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more important than food, and the body more important than clothes? Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? Who of you by worrying can add a single hour to his life?"And why do you worry about clothes? See how the lilies of the field grow. They do not labor or spin. Yet I tell you that not even Solomon in all his splendor was dressed like one of these. If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you, O you of little faith? So do not worry, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' For the pagans run after all these things, and your heavenly Father knows that you need them. But seek first his kingdom and his righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.
Matt 6:25
