In a study published Thursday in the journal Current Biology, Güler and his colleagues demonstrate that the pleasure center of the brain that produces the chemical dopamine, and the brain's separate biological clock that regulates daily physiological rhythms, are linked, and that high-calorie foods—which bring pleasure—disrupt normal feeding schedules, resulting in overconsumption. Using mice as study models, the researchers mimicked the 24/7 availability of a high-fat diet, and showed that anytime snacking eventually results in obesity and related health problems.
Güler's team found that mice fed a diet comparable to a wild diet in calories and fats maintained normal eating and exercise schedules and proper weight. But mice fed high-calorie diets laden with fats and sugars began "snacking" at all hours and became obese.
Additionally, so-called "knockout" mice that had their dopamine signaling disrupted—meaning they didn't seek the rewarding pleasure of the high-fat diet—maintained a normal eating schedule and did not become obese, even when presented with the 24/7 availability of high-calorie feeds.
Güler said the human body, through thousands of years of evolution, is hard-wired to consume as much food as possible as long as it's available. He said this comes from a long earlier history when people hunted or gathered food and had brief periods of plenty, such as after a kill, and then potentially lengthy periods of famine. Humans also were potential prey to large animals and so actively sought food during the day, and sheltered and rested at night.
"We evolved under pressures we no longer have," Güler said. "It is natural for our bodies as organisms to want to consume as much as possible, to store fat, because the body doesn't know when the next meal is coming.

DEFICIENT? Boy! How’d we get someone as superior as you on FR? I bet you’re a riot to be around.
It’s terrible, especially going that skinny. It has to be dangerous to do that.
Could you explain what an 8/16 intermittent fasting regime actually is?
****************************************************
Every day you do all your eating (hopefully, healthy foods) during an 8 hour period and then fast for the next 16 hours. Do the same for the next day and every day after.
See post 24 above for a more stringent intermittent fasting diet. I’m a mere beginner.
I noticed that when I am too tired or over stressed and don’t stop to exercise and do another calming activity, I will seek out foods that are much higher in calories than I normally eat.
It’s really about practice. You build your fasting “muscle” by practice.
Here’s one you’ll never find any support for: the epidemic of fattitude is caused by a Soviet biological warfare agent that escaped the lab.
It’s the only hypothesis that explains all the facts.
Maybe in California you are surrounded by liberal women. Expand your horizons.
Portion size and exercise.
WOW....maybe there is hope for me
It's not good for you. He does it for acting work but he'll likely die much sooner because of it. It's incredibly hard on the heart to yo-yo like that.
There are several different ways to fast. I went with the every other day eat one meal so that there’s a 24 hour period between my last meal on non fast days and my one meal on fast days. I lasted a week doing that until I realized I was starving myself too much which is self-defeating so now I’m doing the 8/16 fasting. The hardest part of this type for me is not eating breakfast right away after I wake up in the morning.

I’m going to try and work toward a 6/18 fasting schedule so I eat only between 10 am and 4 pm.
One reason I like the keto lifestyle of eating so much is that I don’t feel hungry between meals like I did with a moderate to heavy carb diet except when I fast for too long. Maybe at some point I can work up to the every other day fast again but for now I’ll stick with something I can live with without feeling like I’m torturing myself.

That’s our ultimate goal but we know that it is too ambitious (for us, anyhow) as a starting point. The 8/16 (11 am - 7 pm for eating) schedule is plenty ambitious for us. I’ll probably try to go to sleep earlier at least at the beginning. There’s no problem fasting when you’re asleep.
What’s this one number over another thing?
Same here - I can go for higher protein and fat but still need some sugar and other carbs to feel right...cutting back on both while going the protein/fat route seems to work - down 6 pounds in 4 weeks and haven’t restarted my exercise regime yet.
Me too.
Thank you for taking the time to post this.
Good Idea. I will try this.
Very good! Sitting here chuckling.
Well there is the problem with this study.
People aren't mice.
