First, do not do Starting Strength for fat loss and a lot of cardio. Rippetoe would fly to Florida and kick your butt. You’re mixing a pure strength program with a fat loss goal. Rippetoe actually wants people to add some fat if needed on that program to gain strength.
We’ve had 3 people lose 100+ pounds with Indigo-3G and a wheat-free moderate calorie diet, no long duration cardio just conditioning, and no muscle loss – which you may not mind but you will when you’re stalled out with 60 pounds of fat loss to go and already eating 1000 calories a day. Then you’ll gain it all back. Some info on conditioning vs. cardio: http://tnation.t-nation.com/free_online_forum/diet_blog_hammer_velocity_shugart/running_makes_you_fat Any diet and training plan tends to work at first when you have 100 pounds to lose, but let’s focus on losing ALL 100 (or losing 90 and gaining 10 pounds of muscle), not just focus on the first 25. We don’t want you to stall out and regress by losing muscle. If you like weight training only 3 days per week, you could do the Velocity Diet workouts, which are geared for fat loss.
There’s also no need to use HOT-ROX and Indigo-3G together. It won’t hurt you, but Indigo-3G should take care of your needs by itself. Tribex is fine to add if you need it.
