I noticed the article said that 100g of mutton flaps is around 400 kcal.<p>If the average Tongan can or will eat 1kg of mutton flaps per day (like the article says) that&#x27;s insane and definitely a cause of obesity. (Or, at least should be.)<p>I lift weights 5+ times a week (for about an hour) and if I ate over 4,000 kcals I&#x27;d be obese too.<p>I can&#x27;t imagine that average Tongan exerts enough energy to make up for eating 4,000 kcals worth of mutton flaps.
