I'm reposting here what I wrote in the Paleo thread in the Weight Loss forum.

"You do have to make a commitment to a radical change from the standard American diet. You no longer eat processed foods--95% of what's available in a regular grocery store. But, after the withdrawals...I did notice a decrease in swelling and some pain, I no longer have ANY stomach pain or random episodes of being sick to my stomach (which I thought was meds related and happened a few times a month) and I've lost around 30 lbs.

You can have a "cheat day" once a week. And things like whole fat yogurt and ice cream are considered fine.

Where as most people can eat gigantic portions of junk food (popcorn, chips, bread) if you eat high fat/high nutrition foods, satiety is quickly reached.

The idea goes against the established food pyramid. Several small snacks a day diets are giving you little blood sugar rushes all day. The paleo idea is to stop those spikes all together."
