A few important points:

The 2-hour area under the curve (AUC) for blood glucose fell by 36% in the paleo group, compared with 7% in the control group.

All members of the paleo group had normal blood sugar levels after 12 weeks, compared with 7 of 15 patients in the other group.

The paleo group consumed 451 fewer calories per day, without intentionally restricting calories or portions. They consumed 1,344 calories, on average, while the Mediterranean group consumed 1,795.
