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…

I hate having breakfast, especially on work days for some reason. I feel ya

Earlier quoted context omitted.

If your diet is sufficiently arranged to contain as little carbs as possible, this disappears. I went from a heavy lunch person to forgetting to have lunch.

Does the amount of carbohydrates intake impact focus/concentration?

For me it noticeably did. Less carbs => better focus. Of course, anecdata, YMMV etc.

I want to put in a good word for old-school calorie counting. If you don't have good "gut intuition" for how much you're eating, you may find that IF just causes you to eat more in the time you are allowed to eat. CC tells you how much you're taking in, so the numbers tell you when you've eaten enough. I often find that, when I stop at my calorie target (1500), I'm actually not that hungry... but I still have an urge…

I've done CC a few times when I get close to being overweight.

Starting January of this year I cut my calories down by 1000/day, 7k/week, which is roughly 2 pounds (just shy of 1kg) a week.

It's now March 10th and I'm down 19 pounds in ~9 weeks.

Is it a bit tedious to count calories? Yeah, but it's perfectly effective.

Thermodynamically you're never going to be getting energy from nowhere. If you're consuming more calories than you're burning you're gaining weight; fewer you're losing it.

My goal is to lose another 5ish pounds so that I stabilize roughly at my current weight with a maintenance period of the next year or so.

Since James Clear's blog is getting shared because it's old (2012), I will share the OG post that kicked off the intermittent fasting trend: Leangains (2010).

Leangains didn't invent IF, but it did inspire more people in the last decade than anything else, including James Clear (it's the first reference he cites in this article).

Carbs give you a sugar rush and then everything in the body goes into processing them, slowing everything else down.

You can easily test it, eat something like a subway sandwich. Record how you feel. Now take the exact same sub, but as a salad (no bun). You'll feel markedly different.

This all, of course, depends on a ton of individual factors like insulin resistance etc.

The work from Dr. Sinclair, and various other scientist seems to agree that its not just weight and body shape, you actually live longer and have less illnesses throughout your life.

Really fascinating stuff - the Lifespan podcast really changed how I think about all of this. I'm like you and haven't had breakfast in quite a while, but recently started skipping launch as well. A lot harder, but supposedly will feel about the same when my body adjusts.

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 like my breakfast late which makes me more often than not skipping lunch (weekends or vacations for sure) but never thought more about it. It definitely helps keeping the figure but I think I should gather more infos - like, meal records etc - before I turn it into a regular and conscious practice...

I lost over 75 pounds with time restricted eating mostly just one meal a day.

I lost 30 pounds by eating smaller meals. Still had breakfast, lunch, and dinner. Skipping my afternoon snacks helped a lot too.

All these anecdotal stories and it all boils down to fewer calories.
