Women who followed a Paleolithic (Paleo) diet lost an average of 7 lbs in four weeks (4.3% of their body weight) compared to 2.6 lbs (1.7% of their body weight) for women following a standard Australian diet as recommended by The Australian National Health and Medical Research Council according to a new study from researchers at Edith Cowan University in Perth, Australia.

The Paleo diet “encourages consumption of fruits, vegetables, lean meats, nuts and eggs”, while “all products of agricultural origin, grains, legumes and dairy are excluded” the paper notes.
