Works great! It requires will power and the understanding that its not just a diet but a way of life. If you are weak minded, give up easy, or are generally weak you will struggle. I have been on the warrior diet for 3 years now. When I started in 2005 I weighed 265 lbs. I now weigh 190 and I am solid muscle. I follow the warrior and I also follow CFT (Controlled Fatigue Training). I jog in the mornings when I get up for 30 minutes. Follow the diet throughout my day. Then I CFT train at night about 5pm-6pm including stretching. Then I Overeat. You will notice after a couple weeks that you become more alert and your senses will be heightened.
Give it a try and best of luck to you. Remember to always check with your physician first before starting a new diet/training program.
