a very clean diet:
try eating raw foods. it's low fat, healthy and bursting with enzymes/life force. raw fruit, vegetables, greens, nuts, seeds & sprouts. just don't starve yourself- eat a good amount of all these raw goodies and get creative.
you can make banana icecream with bananas alone. just freeze them overnight and blend in the morning- add a couple walnuts and agave nectar for the topping.
make a green smoothie with spinach and lots of fruit- especially pineapple and orange/tangerine- you won't even taste the greens.
make a huge salad with all your favorite veggies and make a delicious dressing with tomatoe, apple cider vinegar, cold pressed olive oil, sea salt and pepper to taste. add a bit of avocado if you'd like.
be light on the nuts and seeds- just a few a day and you'll see results if you're working out as well.
if you want you can lightly steam broccoli or aspargus and enjoy that with raw lasagna.
super easy to make:
