First I stress this is only a single study, but it is interesting.
What if the timing of when food was eaten was as or more important than the type of food?
A study appeared in the May 16th issue of Cell Metabolism that appears to have shown a serious benefit for mice that fastest for 16 hours (straight) a day compared with those who could eat at will.
Both groups ate the same amount of food, but the fasting group was able to handle fat much better.
So if you want to experiment, this seems simple enough ... if you have the will power and promise to be kind to those around you.
I only know the estingboatterns of a few, but some who have had no weight problems seem to not be snackers - just three meals a day at "normal" times. It would be interesting to see if there is a correlation
Perhaps they are eating during these efficient times.
And when I was a kid we first ate at breakfast around 7am and then in the evening around 6 with very little snacking until I became a teen.
One has to wonder if the pre-TV era was marked by 12 hour daily fasts?
I'm going to bet that this isn't a silver bullet, but that timing is important at some level and partial fasting can't hurt (unless you go crazy).
But if it is very important the snack food and restaurant industries need a bit of re-thinking. And there is this other question of what is the impact of the timing of exercise.

While diet-induced obesity has been exclusively attributed to increased caloric intake from fat, animals fed a high-fat diet (HFD) ad libitum (ad lib) eat frequently throughout day and night, disrupting the normal feeding cycle. To test whether obesity and metabolic diseases result from HFD or disruption of metabolic cycles, we subjected mice to either ad lib or time-restricted feeding (tRF) of a HFD for 8
hr per day. Mice under tRF consume equivalent calories from HFD as those with ad lib access yet are protected against obesity, hyperinsulinemia, hepatic steatosis, and inflammation and have improved motor coordination. The tRF regimen improved CREB, mTOR, and AMPK pathway function and oscillations of the circadian clock and their target genes' expression. These changes in catabolic and anabolic pathways altered liver metabolome and improved nutrient utilization and energy expenditure. We demonstrate in mice that tRF regimen is a nonpharmacological strategy against obesity and associated diseases.
► Time-restricted feeding improves clock and nutrient sensor functions ► tRF prevents obesity, diabetes, and liver diseases in mice on a high-fat diet ► Nutrient type and time of feeding determine liver metabolome and nutrient homeostasis ► tRF raises bile acid production and energy expenditure and reduces inflammation
