It's a very good question. Unfortunately it's almost impossible to find good information on nutrition these days because there is so much conflicting information out there, and much of it is hype or simply wrong. Complicating matters is the fact that everyone's body works a little differently, and the dietary practices that work for you might not work as well for someone else.

From a Law of Attraction perspective, if you hold in your mind the positive image of what you want your body to look like and feel like (and, by extension, how well your mind works), your body will be attracted to the foods, activities, and nutrition and exercise information that will make that vision a reality.

In time, if you continue this process, you will find that your body no longer craves those things that are not good for you. Good diet and exercise are a lifestyle. It must be something that you can live with and practice on a consistent basis.

One thing I think many people overlook is that, if you want to eat well, you have to have good things to eat in your house, and eliminate the bad things. No amount of will power can overcome the impulse to have a chocolate chip cookie if it's in the house. There's nothing wrong with chocolate chip cookies, of course, but if you're going to eliminate them from your diet, why have them in the house?

I feel more empathetic and have better dreams on a vegan diet. Also, I don't think murdering animals is good karma and it's harder on the environment than growing veggies. Even so, when I stay on a vegan diet for any length of time, I begin to not feel well physically, and sooner or later will cave in to a big cheeseburger. We are mammals and mammals eat each other. My mind is above that, but my body isn't, so I am working on it!

According to Abraham if your vibrations are algigned with the universe then it does not matter what you eat or drink. The body will only keep what it needs and reject the rest.
