The weight loss, low calorie, low fat don't eat anything nice diets have never worked for weight loss. In fact they can boomerang and cause muscle loss and weight gain. Postmenopausal women have an increased risk of obesity, for instance due to the reduction of oestrogen production in combination with an elevated energy intake and reduced physical activity.
The Paleo diet allows people to eat plenty of unsaturated fats and low-glycaemic carbohydrates—the ones that are lower in sugar—and specifically focuses on vegetables, lean meats, fish, poultry, eggs, shellfish, seeds, nuts and fruits, and excludes all grains and cereals, milk, refined sugars and added salt.In this study of 70 overweight post-menopausal were either put on the Paleo diet or the Nordic Nutrition Recommendations diet, which is like the Paleo but allows cereals and grains, milk, refined sugars and added salt.Over the two years, women on the Paleo diet lost an average of nine kilos (20 lbs) while those following the Nordic diet lost an average of six kilos (13 lbs). But the biggest difference was the overall health of the Paleo-group women. They saw levels of risk factors of type 2 diabetes, cardiovascular diseases and enzymes involved in fat storage decrease. The weight loss in both dietary groups also contributed to reduced inflammation in both fat tissue and in the circulation which is the major cause of chronic illness.
