'Social Jetlag' May Be Making You Fat

sciencehabit writes "A new study suggests that, by disrupting your body's normal rhythms, your alarm clock could be making you overweight. The study concerns a phenomenon called 'social jetlag.' That's the extent to which our natural sleep patterns are out of synch with our school or work schedules. When we wake up earlier than we're supposed to — or spend all weekend sleeping in and then get up at 6 am on Monday — it makes our body feel like it's spending the weekend in one time zone and the week in another. For people who are already on the heavy side, greater social jet lag corresponds to greater body weight."

Yeah sure

Has nothing to do with the italian grinder you went to bed on, just the rhythmic imbalance. Fix that, change nothing else and the fat will literally melt away. Articles like this pander to the ever expanding population of morbidly obese...probably consciously. Editor's meeting: "Write more stories fat people will like, since everybody's fat".

Another suggestion: eat slowly !

We eat tons of food without even realizing.
The satiety comes after a few moments eating, and it differs from people to another one.

Eating in the shortest amount of time doesn't allow the satiety mechanisms do their job.

Actually, that's not entirely true.

A lot of the science now is showing that eat less/exercise more doesn't produce much in terms of results over the long term.
There have been studies done on eating less/deprivation, and the repeatedly conclude that it's bad. In extreme cases, of course (like eating a pound of bacon at each meal) there is room to cut back, but in general the whole idea of introducing fewer calories may not be the cure-all many think it is.

Obesity is actually a sign that we're not giving our body the nutrients it needs, so it stores fat. So eating better (read: more nutritious food) is likely to fix things more easily. Of course, exercise isn't bad or anything, it's just not a cure-all.

Look up sleep apnea. And stop spreading jaded ignorance.

> Your weight is a result of calories in vs. calories out.

Actually, it's not. There are plenty of studies demonstrating that chronic sleep-deprivation makes you MUCH more likely to gain weight from a given number of calories. Your body goes into 'crisis' mode, and becomes more aggressive and efficient about converting calories into fat. The fact that you're likely to end up ravenously hungry and fatigued multiples the effect, but even if you kept exercise and calorie count constant, you'd be more likely to gain weight after extended chronic sleep deprivation.

The same phenomenon has been observed with some psychiatric drugs. In particular, one class of drugs used for treating schizophrenia. I don't remember the exact details, but I remember reading that there were a couple of them that *observably* slowed down the patient's metabolism for reasons that aren't entirely understood (and researchers are certainly trying, because if they can figure out what makes them slow somebody's metabolism down, they might be able to come up with a blockbuster drug that speeds it up and enables effortless weight loss. Assuming, of course, the drug doesn't end up having drug-induced mania or psychosis as a side effect).
