Another, larger study confirms earlier results that time-restricted fasting (sometimes called Intermittent Fasting) does not result in significant larger weight loss.
It might benefit people who need a formal regimen for their lower-calorie diets however. No disadvantages to IF were found.
"Among patients with obesity, a regimen of time-restricted eating was not more beneficial with regard to reduction in body weight, body fat, or metabolic risk factors than daily calorie restriction."
There is nothing about "time restricted intermittent fasting" that is unique to - anything at all. Time restricted intermittent fasting means you can eat only during a specific window lasting between 8-12 hours during a 24-hour period.
Hint: MOST people eat only during a specific window lasting between 8-12 hours during a 24-hour period. If you get up at 7AM and eat something for breakfast before 8, then eat something at noon, and then eat dinner around 6 at night, and don't eat again until the next morning then congratulations - you just ate like a normal American human being and will or will not gain or lose weight based on what you ate - and not the time you ate it.
That is, by definition, time-restricted intermittent fasting. It means nothing, it has no significance. Make sure you digest your food before bedtime. If you go to bed at midnight, then make sure you're done eating by 7 or 8. When you wake up the next morning and eat at 8pm, it means 12 hours will have passed between the time you last ate, and your next meal.
It's not special. It's just normal.
WHAT you eat during those meals matters much more than WHEN you eat it.
IF isn't just about weight loss, and it isn't about eating non stop for 8 hours a day.
Typically, you eat one meal, then don't eat anything for 7 hours (or a shorter gap, if you're doing longer fasts), and then you eat another meal and stop for the day. That makes your blood sugars go up and down, instead of maintaining a high level while you snack all day.
If the study let people graze for 8 hours a day (which is how it sounds in the summary), they would get different results than requiring subjects to eat just 2 individual meals with nothing in between. That's supposed to improve insulin response and do all those other good things for your body.

Sounds like a perfect recipe for disastrous blood sugar problems. Forcing your body into spikes and dives is not healthy. Stuffing yourself twice a day is also not healthy.
Eating something shortly after getting up in the morning (known to most people as breakfast), something in the middle of the day (commonly referred to as lunch) and then something in the evening (often called supper or dinner) is normal, and healthy.
No one is suggesting that anyone eat non-stop for 8 hours a day.

You seem to have a strong opinion about this. Are you a doctor, nutritionist, endocrinologist, researcher? I'm not any of those, but I'm relying on that sort of expert advice, and they say that keeping your blood sugar high all the time is what causes problems. You WANT your blood sugar to come all the way down.
I didn't say "stuff yourself" twice a day, I said eat a meal. I usually have green vegetables and protein, because I'm cutting carbs.
And the way I first heard IF described was that you could just eat whatever you wanted for 8 hours.
That's not how it's supposed to work, but the study did not appear to give participants any guidelines except "don't eat outside these hours", and calorie restrictions.

I guess you didn't actually read the study. Or even skim the first couple of paragraphs. Here's the tl;dr for ya, which is the very first paragraph, first and second sentence:
Quote:
We randomly assigned 139 patients with obesity to time-restricted eating (eating only between 8:00 a.m. and 4:00 p.m.) with calorie restriction or daily calorie restriction alone. For 12 months, all the participants were instructed to follow a calorie-restricted diet that consisted of 1500 to 1800 kcal per day for men and 1200 to 1500 kcal per day for women.

Did you read my post (which you quoted), where I said the guidelines were "don't eat outside these hours", and calorie restrictions.?
The study summary did not say that participants ate healthy food, just a certain number of calories. If you blow all your calories on ice cream, your nutrition is going to suffer.
The abstract also didn't say how participation was monitored. Did the subjects just tell researchers, " Yup, I followed the guidelines"? That kind of study isn't nearly as weighty as one where participants are in a controlled situation where they can't change things up.
I'm not an expert, maybe the studies showing IF to be effective are also flawed. But this particular study doesn't seem to be giving it a fair shot.

I don't know about that. I do eat like that, but I've been surprised by how many people eat a late "bedtime snack," or keep something to eat and/or drink by the bed for when they wake up in the middle of the night, and I don't mean just water. I personally don't ever even drink water during the night!
