Intermittent fasting. A.K.A skipping breakfast

Haha this is what I thought reading the article. One thing I don't think was really touched on was exercise. Am I suppose to exercise during the fat burning period i.e. 12 hours after my last meal?

Many people like exercising just before they eat, especially if you're doing weight training. However, if you're _performing_, instead of exercising (like running a race) then you'll likely want to eat before you start.

I regularly do very high intensity Sports for 2 hours, after fasting for roughly for 20 hours straight

It feels normal, but it may not be for everyone

Keep in mind the Muslim elite soccer players that observe Ramadan and are doing it at the highest level

I've used IF now for a few years and have enjoyed the benefits. I usually only eat dinner. Three observations.

1. It's not for everyone. Give it a try and see if it works. 2. Drink lots of water. 3. Try having a salad or a plate of veggies 20mins before eating your dinner. That helps me avoid over-eating.

It's great way to lose weight if you can keep yourself from overeating when your feeding window opens. It's the same result as calorie restriction. I like stuffing my face instead of eating smaller portions. So I decided to go down to 1 meal a day doing 20/4; I lost around 48 pounds in 3 months.

I also like "stuffing my face" and I can highly recommend sticking to low calorie density foods. For example, I buy bags of frozen vegetables and add them to whatever other main course I'm having. You barely consume any calories, they contain a lot of micronutrients and the volume is enough for you to feel full. There are other similar foods if mixed veggies are not your thing.

For decades of my adult life I skipped breakfast, going against all conventional dietary wisdom. Having 3 meals a day just felt like turning my body into a conveyor belt that produces faeces. Now I feel kinda vindicated. A few times I traveled with a friends who did the breakfast - lunch - dinner thing and after two or three days I had to opt out of either breakfast or dinner. I remember asking "how do you even manag…

You and I are about the same age and I also have an almost identical body to when I was 20. But I’ve eaten three+ meals per day my entire life.

I’ve been doing intermittent fasting (time restricted feeding) with 16:8 (I do at least 16 hours fasting and at most 8 hours feeding window everyday) for several years. It’s more convenient (as with others, I find skipping breakfast easy) and makes night times easier in a few ways (fall asleep fast, have a good sleep, etc.). Social outings in the evening could be an issue since I stop eating by around 6, but it’s not a big deal to break the rule sometimes. If I want to, I can easily compensate by eating a little later the next day.

With intermittent fasting, I didn’t lose any weight at all! I learned that weight management is about what you eat and how much you eat. A reduced feeding window can help in reducing calorie intake. But I do continue it because of the convenience and because I’ve read that it’s helpful in different ways not to be stuffing the body with food for a long time during the day.

I recommend this method of IF to people, and tell them to start with 14:10 or even 13:11, and then build up from there. I’ve heard from some people that they suffer from acidity when doing IF. I haven’t had that issue.

Has anybody here experienced more impulsive behaviour as a result of intermittent fasting? More internal anger, being rude or impatient with your peers or children much more often, etc. I was on IF for 2-3 years, and while I gained a lot from the mental clarity, I also admit turning into an uneasy person within. A quick google provided a 2020 paper that tackles this same question: https://www.ncbi.nlm.nih.gov/pmc/art…

The opposite actually. I used to get hangry and be irritable all the time. I would also have blood sugar crashes if I ate carbs (hypoglycemic). Switching to 18:6 completely eliminated blood sugar issues and I am generally more docile.

Intermittent fasting works because you end up eating less calories. On the other hand, shifting your eating to earlier in the day while eating the same amount of calories leads to weight loss:

I don't have a reference to it handy, but I know Rhonda Patrick talk about this: it takes a minimum of three days fasting in humans to reproduce the effects seen in one day fasting in mice. Her theory is that their metabolism is much faster, and one day is a much bigger percentage of a mouse total life time than a human's.

I lost a lot of weight by skipping meals, but then got stuck. I then started logging my food intake, mainly to keep track of nutrients, make sure I eat adequate amount of fiber, etc... Since I was doing it I decided to be consistent and restrict my calories: my weight is linearly correlated with the amount of calories I eat. I still skip meals for convenience, because I get an energy boost and because it was hard for me to eat small meals, but I'm very conscious of my calorie intake and adjust throughout the week when I end up over or under eat.

I've been doing OMAD since the start of this year and loving it. I'm sat at a computer all day, why do I really need to feed this body if I'm not exerting the same amount out. I find when I eat lunch now, it's a real drag, and since I'm so full after it I don't even need dinner, and can usually wait until the next day around dinner time to find that I'm hungry again. I do get a ~30 minute brisk walk in daily but no w…

My brother-in-law does OMAD. He has discovered another advantage to it. He had to go to another city for a week for work. They put him up at a nice AirBnB, and... they gave him a $60 food per diem. $60 if you're doing 3 meals? Nice little treat, I guess. $60 if you're doing 1 meal? He eats like a king every night. Now, in this case, it may not be helping him lose weight haha!

The beautiful thing about OMAD (I’ve used it to lose weight quite effectively several times) is that it’s rather difficult to go over your TDEE in one meal no matter what you eat. In fact, when you are trying to maintain a weight instead of lose, you often have to make a concerted effort to make even the minimum amount of calories to maintain.

It’s possible to lose weight eating nothing but an entire frozen pizza every day this way. Not that I would recommend doing that, it’s definitely not healthy. But possible.

I started intermittent fasting in September and I thought I would do it only to lose my corona weight gains. But by now it's a lifestyle for me that has so many benefits. To be fair, breakfast was never that important to me. I typically start the day with a few cups of coffee with milk and going to black coffee without milk was and is funnily the biggest price I have to pay. To cut the junk food after 8pm has so many…

Coffee on an empty stomach is quite hard on the stomach. One thing I learned recently is that gut damage from unhealthy eating habits can accumulate over long periods of times, and symptoms manifest decades after. So if you notice any uncomfortable feeling from this habit (the all too common coffee diarrhea for example), it wouldn't be a bad idea to skip the morning coffee or at the very least prepare your gut with some food and water first.
