Avoid the chain supermarkets for Atkins. Around here they charge full-price. Here (Renton,WA) the best places are Seattle Super Supplements on Rainer near Walmart (large selection, discount prices) and Walmart (lowest prices, very small selection).
For me, Atkins has worked. I've lost 28 pounds since April. Both my wife and I are doing it together. I hated low-fat diets, always hungry, food didn't taste good. There are some really good recipes in the Atkins' books. Also, I need 3 less hours of sleep per night! And my pulse rate no longer maxes out when I do kickboxing aerobics. Give it a try.
