Study confirms whole grains as key to reducing belly fat. Federal Center for Nutrition (BZfE) recommends as a rule of thumb that the waist circumference should not exceed 88 centimeters for women and 102 centimeters for men.
A combination of different whole grain products, including oats, quinoa and whole grain bread, can not only help you lose weight, but also regulate blood sugar levels. According to experts, up to five kilos of weight loss per week should be possible - with intermittent fasting.
