Remember “muscle confusion”, invented by the P90 guy? Lol
Now, we have metabolic confusion? Lol
Until you link to the peer reviewed research study, I’m calling total BS.
Muscle confusion" really is rooted in fitness science. The basic science marketed as "muscle confusion" comes from research at PhD level you can download s paper on the subject.

Neither one of these links has anything to do with the pseudoscience known as "metabolic confusion." Try again.

I've never understood the idea of "confusing" my body. Shouldn't we be on the same team? Will it try to confuse me for revenge?
OP, if you're still here, your schedule is fine assuming you have the energy you need throughout the day and you're eating the right number of calories for your goals.7 -
AnvilHead, Isn't eating meant to fuel the body? Eating a large dinner at 7:30 doesn't seem smart. I go to bed around 9:30... not leaving my body much time to use that food. Maybe it will be stored if the carbs aren't used initially?... You're stomach never rests, but if there is nothing in it... the body will pull from other places (fat, muscle) for the energy....
1) The first error is assuming that the body won't "use" that food while asleep. Everything in your body is still functioning at night, and it takes energy to fuel it. Your brain is still working, your central nervous system is still functioning, your heart is still pumping, you're still breathing, your body is constantly in the process of digestion, nutrient transport, cellular repair, balancing all the hormones, etc. necessary for homeostasis and a ton of other functions. You don't go into suspended animation when you sleep. Your brain and liver are the two organs in your body which use the largest percentage of the energy needs which constitute your BMR, and both of them are still fully functioning while you sleep (see research review here.) As shown in the research review, your liver, brain, kidneys and heart constitute around 70-80% of your resting caloric expenditure - and guess what? All those things are busily working away while you're sleeping.
2) The entire process of digestion takes longer than most people think. While your stomach empties in a few hours, the food remains in your intestines (where it's further digested/metabolized/absorbed) for up to 30-40 hours. It's not like you eat and your body is all done with that food and has neatly tucked it away into compartments by the time you're done sleeping.
3) There is no net storage of fat in a caloric deficit, regardless of what you eat or when you eat it. There is certainly some storage of nutrients, or your body wouldn't function - but that doesn't mean it automagically turns to fat. There are actually very limited and rare circumstances where carbs are converted to fat. Carbs are primarily metabolized into glucose (which is used for cellular processes) and glycogen (which is stored in the muscles and liver).
4) The thought of your body only pulling from other places when your stomach is empty, or only when you're asleep, makes the assumption that the process is like a light switch - on or off. We're in a constant flux between anabolism and catabolism all day, every day, and it's not a light switch, it's a continuum.15 -

Nonsense...
Its not ... its valid ... The metabolic confusion is a strstetgy and employers a concept of dieting known as “calorie shifting”... its what you want ftom intermittent fasting.
I think my metabolism must be amazing then, mine has never seemed confused before.
Edit to addI just woo'd 2 of your posts as you seem to like to know for some reason.
Well thank you for helping to perpetuate bro sciences. Well done you. Im talking about good well established practice and science.
Actually you're not. You're talking about woo and BS which completely ignores/contradicts basic physiology. In other words, perpetuating broscience. There is no scientific basis for basically anything you've said.14 -

Here is my schedule:
Wake Up
No breakfast (Black Coffee only)
Lunch at 11AM
Dinner at 5:15PM
No snacking
Bed
I eat all of my calories for the day between 11am-5:15pm in the day. This gives my body 17 hours of fasting through the night/morning hours.
I wouldn't really consider what you're doing as fasting, billions do and have lived perfectly well on two meals a day. Its only modern western convention that says we should eat three meals a day. To me, fasting is not eating for days on end, nothing. Fasting isn't what they do in Ramadan either, that's a total cop out.
That's why it's called "intermittent fasting" and not "fasting" proper...

Not arguing at all. All points are valid.
One question though as it relates to sleeping. There are a few differences. For instance, I have read that your heart rate slows but your body heats up. This is supposedly a process that ensures you get rest (slow heart rate), but stay safe (warm).
I only bring this up out of interest. I realize it’s off-topic but maybe relevant as your body does some tricky things while sleeping. While I don’t think you go into suspension or anything, things happen that are different when you are awake.
I don’t know if any of that is relevant at all. Probably not. Just thought it might be worth bringing up.
If the sleep tracking on my Garmin is any indicator, the heart rate certainly does go down while sleeping. My heart rate stays from the high 40s to low/mid 50s pretty much the entire time I'm asleep, and you can then see the elevation after I get up and start moving around. I'm not sure what body temp does during sleep.
I'm no expert on sleep, but I'm sure the body does different things while sleeping. IIRC, EEGs show that your brain patterns are altered, you're moving around less than when you're awake, etc. Nonetheless, all your involuntary functions (metabolism, respirations, circulation, etc.) are still going on, so energy expenditure is still happening via all the nonstop physiological processes.
Of the four processes that expend energy (BMR, NEAT, EAT, TEF), BMR is the main one still happening while you sleep. For most people, BMR constitutes about 65-70% of their daily energy expenditure, so what I was addressing was the apparently pretty common misconception that the body doesn't burn anything while we're asleep and that any food remaining in your stomach/intestines will instantly be converted to fat because you didn't "burn it off" before you laid down to sleep.4 -
The thing I don't understand about that belief is why not burning it off while sleeping (let alone not continuing to digest it) would mean that you would add net fat. The amount you take in and the amount you burn within the 24 hour period is not affected by when you eat, right? I just really don't get WHY people think it matters, beyond the fact that it's been one of those things people say for, like, forever.7

IF is an interesting subject. I'm glad I found people talking about it. I once just disregarded it until I used it with low carb, high fat dieting and wow, I am back to losing half a pound a week.
Of course at first I Iost about a pound a day but we all know weight loss like that is probably mostly water. So when I had some salt and plenty of water, my weight loss went back to more reasonable levels.
But it got me out of my weight loss stall...I had lost 20 pounds on LCHF but though I was still losing inches off my waist, I wasn't losing weight. I needed to lose another 20 pounds to get back to a normal weight, BMI not in overweight category. A 500 calorie a day fat fast kicked it off then I went to one meal a day. When I was just low calorie, I could never make it through a day of 1 meal only, without being so ravenously hungry I would eat 2000 calories in one sittting. I just couldn't help it. I was just too hungry. But combining it with Low Carb eating and mild exercise and wow. I'm back on the road of weight loss again.
So, is anyone else getting good results with combining low carb and IF? Will I eventually stall out again? Will my hunger levels go crazy again? Anyone with direct experience?0 -
I had a go over 6 months ... stabilised after about 4 months however month 5 reintroducing 500 calorie into the late mesl .. it went yoyo. I couldn't keep it working. Wasn't for me.0

At the risk of being dragged into this debate, by any chance is "metabolic confusion" supposed to refer to metabolic flexibility? Which is normal physiology for the body to burn predominantly fat during rest and low intensity activities, and relying more on glycogen during intense activity.1

I think of it as a side shoot of Calorie shifting....2

If we were able to "confuse" our metabolisms we would have become extinct a long time ago...5

My metabolism is confused for sure. It’s lost it’s way and has not returned to me in years.4

I have to give a shoutout to IF aswell. Lately I haven't been feeling like eating in the evenings at all, so I've sort of eased my way into it a little. The only real difference I had to make was delaying my breakfast a little bit. So between noon and 8pm I eat whatever I feel like basically. I don't binge or anything, but I have healthy meals with meat and lots of veggies and some carbs.
I've only done this for some days now but I've seen a consecutive loss every single day, and I think what I really am starting to like about it is the not feeling stuffed, in fact I've come to appreciate the lightness of not being constantly in a digestive process. That lightness seems to just get better and stay throughout the day so it's going to be fun to see how this develops. Especially it's going to be interesting to see how this copes with my golfing season that's about to start.0 -
I started this last week. My goal is 1200 calories for the day and I have meals about 1 p.m. and 7 p.m. I like it simply because I'm full after my meals. When I divided my calories throughout the day, I never really felt full. (And I'm eating the same type foods, barring the oatmeal I'd usually have in the morning.) When I get up in the morning, I'm a bit hungry, but I'm not starving or having cravings. It hasn't been difficult waiting until the early afternoon. Some days I could go longer and one day I might go for a 24-hour fast. I'm happy doing this for now.0

It's not what I want from intermittent fasting. What I want is to be able to use most of my cals in the evening when I find I'm hungrier than during the day. It's a calorie intake/timing restriction for me, nothing more.
This is exactly what intermittent fasting should be used for. Satisfying your hunger and sticking with your caloric and nutritional goals. Many people find it easier and more satisfying to have fewer large meals in a smaller window vs. trying to plan/manage those calories throughout a long day. Personally, I love going to bed with a full belly.
