Query: Doesn't work for everybody

I was on the Protein Power plan for a year and a half. Three meals a day was red meat, cheese, and eggs. My weight went from 192 to 192; my cholesterol soared from 143 to 210! A few months ago, after finally being forced to conclude that the plan simply wasn't working for me, I went back to eating rice, beans, noodles, bread, and cereal. What do you know: my cholesterol has already plummeted to 172. But... right after I started on the plan, I turned my brother on to it. He dropped 15 pounds almost overnight and leveled off at a 20-pound loss. So give it a try; it may work for you. It didn't for me. But nothing works for everybody, not even aspirin or condoms.
