To lose weight, learn strategy from the experts

For people who want to lose weight, it is wise to learn healthy strategies from nutritionists.

Fan Zhihong, a renowned researcher in nutrition and food safety at China Agricultural University, said the general principle for losing weight is to exercise and to eat a healthy, nutritious diet.

The diet should feature foods with high nutrient density, high satiety index (a ranking of foods' ability to satisfy hunger), low energy density (low in refined starch, sugar and fat), and low glycemic response (a food's effect on blood sugar), with enough intake of protein, vitamins and minerals, she said.
