So how effective was the Evo Diet? A typical participant was Jon Thornton, 36, a driving instructor from Sheffield - John lost 5.7kg (12.5lbs) on the diet, and reduced his cholesterol by 20%. His blood pressure also fell.
Overall, the group saw their cholesterol levels drop 23%, an amount usually achieved only through anti-cholesterol drugs statins.
The group's average blood pressure also fell dramatically, from a nearly hypertensive 140/83 to 122/76. And although this was not designed as a weight loss diet (there were plenty of calories on offer), participants dropped 4.4kg (9.7lbs), on average.
While it would be hard to duplicate a diet such as this at home, the Evo Diet shows the profound effects that our modern diet has upon our health, and how the inclusion of more fresh fruit and vegetables can improve several key health markers.
