One big meal a day.

What Ron, said we ain't rats, and the principle doesn't apply to us.
You can have a big meal a day. I often do that.

Nutrition timing debunk is the big eater's heaven.

HA! People on here getting so passionate and argumentative over the one-meal-a-day question. Too funny.

Anyways, without going into loads of crappy pseudoscientific "research" I can say that keeping a more steady blood sugar lvel throughout the day may make you feel better, although obviously the jury is out on whether this will benefit your weight loss.

Meal timing <> blood sugar level. You could eat 3 meals with an explosive GI or one meal with a low one - also for healthy people, blood sugar levels are well regulated (as cholesterol) canceling de facto the relation between weigh loss and glycemic index

I sometimes do. It just depends on how my day is going. I work nights and sleep is very important to me. If it means short changing my sleeping hours then I will eat most if not all my allowed calories in 1 sitting.

Are you really only going to eat one meal a day for the rest of your life?

Exactly. It probably isn't a problem for short term weight loss, but you'd be better learning eating strategies you can stick with for the rest of your life.

Be careful your pancreas and liver is going to under a lot of pressure.

edited. wrong topic haha

Eating one meal a day is not heatlhy - it slows your metabolism down and stores fat

Myth.

Be careful your pancreas and liver is going to under a lot of pressure.

I would think so.

What you imagine and what is actually happening are two entirely different things. There's no evidence that meal frequency has any effect on the liver and pancreas whatsoever.

I've done both, and have lost weight doing both.

My issue tends to be my blood sugar levels, more so than my metabolism. My body is extremely sensitive to going long periods without eating, and I experience the following side effects if I don't eat every few hours : my concentration wanes, I get shaky, I become short tempered, and sometimes I even get lightheaded.

If you don't experience the same side effects and you are losing weight - AND this is an eating model that you enjoy and can sustain - then it seems that it would make sense to keep it up.

One note about nutrition vs. calories. I know it's certainly possible to eat all your CALORIES in a single sitting (hello Italian beef sandwich with french fries!), so the challenge becomes making sure that what you are eating also supplies you with the proper NUTRIENTS to sustain you throughout the day. It could be as simple as adding a small spinach & blueberry salad as a side to the above mentioned beef sandwich & fries, and leaving a bite of the sandwich and 2 or 3 fries on the plate.

Good luck in your weight loss and lifelong maintenance journey!

Eating one big meal a day falls into the category of Intermittent Fasting. Theoretically, it's a much more natural way to eat. Caveman probably didn't snack every 2 hours. He ate big when the food was there. Also, theoretically, it's better for you body physiologically b/c diabetes (which is one of the major problems caused by obesity) is caused by insulin resistance. Regular fasting would likely prevent your insulin receptors from becoming resistant, whereas continued eating throughout the day may contribute to insulin resistance.

Notice that all this is theoretical. There have been some smaller studies looking at IF and the results are promising. We don't know whether there are any big differences compared to regular eating in the long run. Basically the jury is still out. The most important thing is definitely to find a diet that works for you. So if IF works, thats great. It's most likely not bad for you. But whether it's optimal is unknown.
