Looking at Sam Feltham, he appears very obesity resistant naturally (lanky and tall) so I doubt he could put on much body fat even eating total garbage. These experiments have been tried before in highly obesity resistant people, and they invariably end the same; whether they eat chocolate cake or whether they eat bacon: naturally obesity resistant people CAN NOT store much body fat; they retain grossly less body fat than anticipated, if they store any at all.What I find most interesting of this experiment is not that Feltham didn't gain (that is what I predicted), but I find it most interesting that Feltham actually managed to eat 5000 calories every single day of a ketogenic diet. In most over feeding studies the participants become so nauseated and repulsed they vomit and simply can't make their calorie goals every day... and that's utilizing easier to store foods like sucrose that spike insulin.
It is just as hard to over feed every day, as it is to under feed every day. Sure, today I can probably eat 1000 calories, or 4000 calories, but tomorrow I assure you I am going to auto-correct. I would love to ask if there were any nausea/vomiting episodes or close calls?
Anyway, the reason I am giving shout out to him is because he's advocating the insulin hypothesis / controlled carbohydrate intake to attenuate pathological fat storage and for that I send BIG SUPPORTS. It's so rare to find a person with no vested interest in this thing who "gets" it and I support all of them. He does have a diet book business , but no personal history of obesity or diabetes. His insight is commendable. I also really liked his personal anecdote of being mis-diagnosed with cancer as a child, and he might have died if not for the fact his mom defied doctor's orders. I also had a similar experience at 16 and I too credit this for my skepticism (or insight) into the tremendous weakness of conventional medical advice or "experts" opinion.
I like his "limescale" anology regarding how the endocrine and nervous system dynamics of the obese individual promotes gradual accrual of body fat in adipocytes culminating in obesity. This is a good, non technical, non jargonish way to get the message across to medical info allergics. Unfortunately, in taking this approach he leaves himself open to attacks from Big C, whiny Guyenet, McEwen, et al. ...but who really cares. If even 1 chubby grandpa stops eating crappy carbs and sugar after reading this, IT IS TEH SUCCESS, and worth the steam coming out of Kocur's ears.
Here is a sample menu. Hard to imagine this was 5,000 calories though, unless he added JMesque portions of butter ;)
Breakfast – Scrambled eggs with salmon and green beans
Snack – Walnuts
Lunch – Mackerel with green beans
Snack – Pecans
Dinner – Topside beef steak with green beans
Snack – Almonds
Meh! I will always support a sane low carb diet w/o gimmicks wherever spotted! Double bonus points if the person has insight enough to see this w/o first hand experience.
