Unless you already have it, I'd recommend the purchase of The Warrior Diet Fat Loss Program E-book.
In this way, you can incorporate the Warrior Diet principles, as well as see an application oriented program defining 'High Fat,' 'High Carb,' and 'Low Carb' (which I found a bit vague in the text). Furthermore, as an E-book, delivery is immediate. You will be able to start the diet tomorrow, as planned.
Having applied the Warrior Diet principles, for some time, without the assistance of the E-book, I have developed a significant regard for its value. Hopefully, you will derive the same benefits.
The Stubborn Fat Solution E-book contains more information regarding the use of Defense Nutrition supplements (which I use). In addition, it has some interesting information regarding the application of the Warrior Diet to people with special needs (e.g. diabetics, athletes, etc.). However, I find its hard sell approach a bit off putting. The aforementioned E-book was far more helpful in my own pursuits.
With regard to supplements, I use Defense Nutrition's multi-vitamin, amla C, and the detox kit (in addition to Warrior Milk and Warrior Whey). As these are the only products I've used, I wouldn't be qualified to recommend any other Defense Nutrition supplements. That said, I would like to reiterate that you'll be better served to apply the diet correctly than worrying about which supplements to include at the onset. Of course, that is only my opinion, and like most information on forums should be taken as such.
Good luck with your nutritional goals in the New Year.
