How to eat like a sumo wrestler


If you want to become obese like a sumo wrestler you may want to eat a lot of carbs, like they do. And by a lot of carbs, we mean a thousand grams per day… or ten bowls of rice at every meal.

At least if you judge by this study on what sumo wrestlers eat, as illustrated above by Dr. Ted Naiman.

The sumo wrestlers are basically on an extremely low-fat diet. Why do they eat mostly carbs, instead of fat? Perhaps because carbs stimulate insulin, the fat-storing hormone, so that they can increase their body fat.

If you do not want to look like a sumo wrestler, you may want to go more easy on the carbs.

    Doesn't that study make you rethink intermittent fasting?

    The author seems to be blissfully unaware of the fact that high-level sumo wrestlers don't actually have particularly high body fat percentages. They're simply very large overall, comparable to power lifters or strongman competitors. So no, their high-carb diet isn't the reason they're that big, it's simply the large overall caloric intake. What a surprise! Incidentally, the linked study says exactly that, too. (Oh yeah, and the study is 40 years old...)

    As most people know: you WILL gain weight on LCHF with too much calories if you're not very gifted. Me too if not careful with listening to my body...

    Average weights were ONLY 100 kg, (220 lbs) which is not uncommon now. Somo ate slightly more than double what the average JapaneseI did, but in two meals rather than three, or 3x as much per meal but one less meal. I found it amazing they blamed eating only twice daily, rather than thrice, for the additional weight gain. No mention of the six hours of exercise each day, much more than the average Japanese. This study was before "low(er) fat" or 30% not 45%, became all the rage. They ate only 10% fat.

    I'm 5'8 - 115 lbs eating a high carb vegan diet. Averaging at about 500 grams of carbs with NO excercise. Guess I could never be a sumo wrestler. Also, of carbs make you fat why is everyone else in Japan and Asia in general extremely lean? Well, not the ones that eat high amounts of protine... they are always the bigger ones.
