According to Dr. Haub’s Facebook page on his experiment, he lost 26.6 pounds over 10 weeks, going from 200.8 pounds and 33.4% body fat to 174.2 pounds and 24.9% body fat. So, at the beginning he had 67 lbs fat mass and 134 lbs lean mass, and after ten weeks he had 43 lbs fat mass and 131 lbs lean mass. Thus, he lost 24 pounds of fat, which requires the metabolism of 84000 calories over 70 days. This means he had a caloric deficit of about 1200 calories per day. Haub's sample diet record shows a food energy intake of about 1600 calories per day (more on this below).
Paleo analysis of the Twinkie diet.
I've just arrived at Le Corre's training base in the Brazilian rain forest. For the next 3 days, he'll be teaching me one of humankind's oldest, trickiest, and most indispensable physical disciplines. Le Corre calls it "Natural Movement" -- or "MovNat" in its French abbreviation -- and to explain what it is, he points at Zuqueto.
"This guy is in amazing shape," Le Corre says, speaking Brazilian Portuguese with an almost native accent. "He's strong and he has great endurance. But what happened here? All he had to do was get on top of this pole, and he couldn't. I can do it. Zuqueto's great-great grandfather could probably do it. At one point in time, just about every man alive could do it. But Zuqueto can't. And why? Because his body isn't smart enough."
A smart body, he explains, knows how to convert force and speed into an almost endless menu of practical movements. Hoisting yourself onto a pole may seem as trivial as a circus stunt, but if you're ever caught in a flood or fleeing an attacking dog, elevating your body 5 feet off the ground could mean the difference between safety and sorrow.
And with that one word -- "practical" -- Le Corre exposes a key weakness in modern exercise: Our workouts are domesticated, while the world out there is still plenty wild. In a pinch, can a man put gym-generated biceps and tank-tread abs to any real use? Could it be that our treadmill-running, elliptical-gliding, well-oiled Cybex world has turned us into show dogs who can't hold our own in the hunt?
Dr. Hindhede discovered that potato protein is high quality, providing all essential amino acids and high digestibility. Potato protein alone is sufficient to sustain an athletic man (although that doesn't make it optimal). A subsequent potato feeding study published in 1927 confirmed this finding (17). Two volunteers, a man and a woman, ate almost nothing but potatoes, lard and butter for 5.5 months. The man was an athlete but the woman was sedentary. Body weight and nitrogen balance (reflecting protein gain/loss from the body) remained constant throughout the experiment, indicating that their muscles were not atrophying at any appreciable rate, and they were probably not putting on fat.
