In 2008, researchers at University of Minnesota made 38 people who were all overweight eat according to a precarious nutrition program for eleven weeks. Every day the participants ate 750 calories less than the recommended daily intake, and of course everyone lost weight. But those who had high levels of vitamin D in their blood at the beginning of this research had a much more efficient weight loss. They lost up to 70% more fat than the other participants.

 

With this background, "the vitamin D diet" developed. A method that briefly contains of you eating vitamin D combined with five other fatburning catalysts (read about them under the picture ↓). By including these key ingredients in your diet the body's fat burning process will constantly be at full speed, according to the authors of the book The Vitamin D Diet.

Women who eat protein twice a day loose on average 4% more fat than women who doesn't, according a study at University of Illinois.

Most foods that are high in vitamin D also contains omega-3.
