If you don't control people on a high carb diet, there is a massive swing in blood sugar and insulin levels every two hours or so as they binge eat. Enormous amounts of willpower can push thru that, or a low carb diet destroys the appetite. Either way if a fat person eats for 16 hours a day unrestricted that'll be about eight cycles of super high blood sugar and the resulting hypoglycemic insulin crash followed by about eight episodes of binge eating. If the same person limits their food intake to only 8 hours a day either via appetite suppression due to lower carb diet, or willpower or external force, they can only get about four cycles in of super high blood sugar followed by insulin spike followed by hypoglycemic crash followed by massive binge eating. It seems likely that four cycles of binge eating per day will cause less "metabolic syndrome" damage than eight cycles of binge eating per day. Even if the total caloric intake is the same, the body at least has more time to recover. The above "seems" to be what they verified in the paper.
