Gareth Davies, Editor at The Telegraph, tried US President-elect Donald Trump's fast-food-based diet for a week. "I've never felt more unhealthy...I don't understand how Trump is still alive," Davies said after the diet experiment. He followed Trump's diet which includes no breakfast or lunch, Doritos for snacks, 12 Diet Cokes/day, and McDonald's, KFC, pizza or a well-done steak for dinner.
