Teri's program is similar to Body for Life - I'm doing it now - not to the letter, but pretty much to the program, my 53 year old girlfriend, who was not overweight to begin with (5'5, 133lbs) lost 8 pounds and reduced her body fat from 30 percent (surprising since she is a regular super exerciser) to 23 in 3 and a half months.....and with LESS pounding workouts, just more efficient ones....the steady state glucose levels from regular eating, makes you feel really good....
