Hi, Nelson88! I have high blood pressure and am doing 5:2 eating within the 16:8 window. Now I am incorporating the new 800 calories a day program for a quick start to increase weight loss. I have been doing this for a year and, so far, my blood pressure has not gone down. I am still hoping that eventually it will, even though I am a senior citizen. I can’t speak to your husband’s situation but it might be worth a try for the health benefits. He might fall into the skinny/fat situation. His fat is only internal around his organs but he doesn’t look fat. That, apparently, was what Dr. Mosley had and he lowered his blood pressure, according to his book. Good luck!
