Of course, actually getting out and exercising again has helped a lot, thanks to my company finally opening up a gym on the 3rd floor of our building in downtown Houston. It's far too easy to slip into a sedentary lifestyle.
My favorite smoothie recipe, from Mark Sisson, with a little alteration:
1 cup raspberries
2 dozen blueberries
4-5 medium-sized strawberries
4-5 blackberries (optional)
10 oz. cold water
Put it all in a blender and liquify. I then put it in a large glass and add a few ice cubes to keep it cold. It's quite delicious and really does fill me up. I've been have a smoothie almost every day for lunch.
One other key has been the total elimination of bread from our diet. We are trying to go totally gluten-free, but that can be a challenge, as you will find gluten in an enormous number of items, from foods to cosmetics to shampoos.
Primal Fuel is the creation of Mark Sisson. My favorite flavor is the Chocolate/Coconut. Here is the nutrient breakdown for Primal Fuel.
