"I still try to adhere to a low carb diet, eating mainly meat and vegetables and severely limiting my intake of bread, pasta, rice and potatoes." - I think this is a much larger player in his weight loss success than he may realize.
Its interesting that I don't notice any discussion of caloric intake on either model -- if he was eating the same except skipping one day of food later, then you are looking at a ~14% reduction in weekly caloric intake, which, without any special effect of fasting, you'd expect to turbocharge weight loss.
"Turbocharge weight loss" means that there is existing weight loss to turbocharge. If you are losing weight, reduce weekly calorie intake by 14% and change nothing else, I think the description is accurate independent of the pre-existing intake level.
