Your head hurts.

For me:

If it comes from exercise and I can eat what feels like enough, I don’t notice. Like, literally lost 30lb when I started Jazzercise after having my last kid and had no idea, thought I’d just ‘toned up’ and was confused I needed new clothes, I was underweight by the time I realized, because I was not eating enough to fund the workouts. Appetite did not adjust.

If it comes from diet or fasting, I feel fine in the daytime but it is a migraine trigger. I feel so good going to bed kinda hungry but it makes wake up feeling crappy and also messes up my sleep.

If it comes from anxiety or emotional upset, well, it feels better than eating (I get stress anorexia definitely cannot eat when upset).

My husband said bulking, gaining weight and working out, was the best he has ever felt, physically.

I’ve fasted – like, just water and vitamins – for a week before.

I found that I was hungry, especially for about the first two or three days, but that I mostly ignored it after that, though I did find myself paying more attention to food ads and stuff like that than normal.

I was significantly cooler. I assume that the metabolism cranks down. I needed to wear heavier clothing than normal to feel comfortable.

I felt like I had less energy to effortlessly run around. Like, I could get up and go somewhere, wasn’t weak, just felt more like something you’d think about doing before doing.

Don’t need to hit the toilet much. That’s neat. Do need to stay hydrated, which I found to be surprisingly easy to forget about without sitting down for a meal.

I wasn’t trying to push myself physically while doing that, though.

I’ve also tried running a long-run calorie deficit where I wasn’t fasting, but also wasn’t eating much – something like 500 calories a day or less – for a longer period of time, for months, and then did a ten mile bike ride a day – there are calories coming in, but they’re considerably less than what you’re burning just living. I found the biking to be kinda rough. It just yanked all of the sugar out of my blood. Had a couple times doing that when I had my vision start to gray out at the end of my ride, needed to stop and get my head down. Was kinda like a zombie after my ride for a bit. Also was colder, just as when fasting. While it’s doable – I lost a bunch of weight doing it – I have to say that I think that it was rather harder than just outright fasting and not doing the exercise. Every time I ate, I felt like it kicked me back into “being hungry mode”, and it was only really physically a strain during the bike ride.

I had a harder time mentally concentrating on things when I’m doing that. Haven’t tried quantifying it, but I’d say that I was less-productive while doing that.

It depends. If you eat frequently, regardless of how much you eat, you’re going to feel hungry relatively soon at any given point. So, eating at a deficit just amplifies that. It’s hard to ignore.

However, I’m a big fan of fasting (though I haven’t been very consistent with it lately). Once my body eventually gets used to not eating multiple times per day and instead, say, eating one big meal once per day, I don’t feel hungry at all until dinner time.

Even if you do eat at a reasonable deficit, and your daily meal is healthy/has enough fiber/protein, it’s way more likely to satiate you.

Not really related to the post, but if I’m doing OMAD (one meal a day) consistently, fasting also makes me feel great. I get a noticeable increase in energy and mental clarity.

You’ll feel the cold much more.

But after some time, the stomach adapts and you don’t really feel that much hunger anymore.

Just can be, that you produce a Gastritis, because the stomach wants to dissolve something and after some time it’s itself.

Also, muscles will be used, after fat, and you lose weight in a not nice way.

It’s (imho) also really hard to get back to regularly eating normal meals.

After a few weeks of stress and not eating much (last week was like 1.5 sandwiches the whole week), I needed quite some time to be able to process a real meal again.
I would eat a few bites, get the sweats and want to puke.

But the was a bit of an extreme case - at least on countries without famine…

IDK about others, but I get hypoglycemic which makes you feel drunk. And not the fun, “I’m buzzed” kind of drunk, but the “oh God make the room stop spinning” kind of drunk.

Deficits are a funny thing.

How are you doing it? How long for? How big a deficit?

Previously its been hard, but I did a lot of research about macros, meals, using fat content to slow digestion etc… Once I got my diet dialed it was easy, because I figured out a few meals that were FUCKING HUGE and still low enough in calories that I got to be “full” at least once a day and hit all my nutrients.

That being said I’m on the last 2 weeks of a 750 cal deficit for 12 weeks and yeah, its starting to get real. Ive had a couple of days this week where Ive said “Fuck it” and had a second protein bar after dinner taking my deficit to only 500. After this I’ll be transitioning back to maintenance cals for 8 weeks although I have promised myself a “Mega blowout” meal of a whole costco pizza and I can eat until I dont want any more pizza in 1 sitting.

Its not so much that you feel “hungry” but you learn to love the feeling of not existing on a sugar and fat cocktail 24 hours a day. I think I’m actually going to have trouble readjusting to an extra 750 cals a day, let alone going onto bulking cals at some point.

I get cold easier and my clothes keep getting looser but that’s about it. I don’t count calories so I’m not sure when exactly I’m running a deficit or for how long but I have been steadily losing weight. I was a few pounds into the overweight range when I decided to start losing weight, now I’m down at least 14% from my peak and basically right in the middle of the healthy weight range for my height. About a year ago I started eating less, and started only eating until I didn’t feel hungry, and significantly reduced my alcohol intake. Its about the laziest diet possible because I still eat whatever whenever and still drink regularly but the net result is I’m running a calorie deficit often enough to lose a fair amount of weight. It doesn’t really feel like anything, or it feels about the same as running a calorie surplus. I imagine if I was running a larger or more sustained deficit it might be unpleasant and feel like starving but a minor irregular deficit isn’t something I really notice.

Weight loss.

Hunger

pretty cool, i highly recommend.

all the people saying"hungry" are incorrect, your body locks into new eating patterns pretty quickly.

if you start OMAD, one meal a day, after a couple days you don’t get hungry until the food window you normally eat at.

fasting gave me a sense of control over my body that I hadn’t really accessed before.

I also just felt a little high after a few days, so things are a lot more interesting in general while fasting.

I like fasting, I do omad everyday, 2 days every now and then and I’ll fast 4 days to a week occasionally.

you know what else is really cool about fasting, my runny nose and all the little itches and all that stuff are gone.

I should stop talking, I can talk about this forever.

give it a whirl, fasting is fun.

saves a ton of time too, once you realize how much time you spend commuting to/from or consuming food or using the bathroom because you eat three or five or seven times a day.

Time that could be spent on lemmy answering questions about not eating hahaha.

I’m in a calorie deficit from switching to a mostly whole food (and plant-based) diet, which is rich in fiber and water. I actually feel full every meal and satiated for much longer after eating than before, due to the fiber and water bulk in the healthier, less processed food.

I did a 1000-calorie daily deficit for a few months, in order to lose two pounds a week. I got used to being hungry all the time after a couple of weeks, but having a lot less energy and being sleepy during the day were harder to deal with. My body was trying to conserve calories that way, but pushing through it was possible.

The hardest part was actually accurately counting the calories. It was relatively simple for off-the-shelf food, but a lot more annoying for things someone else home-cooked for me. I had to ask for the recipe every time, weigh how much I ate, and then track the calories per ingredient on a spreadsheet. Restaurant food was effectively impossible to count, but that didn’t matter much because I was so focused on filling food that I wouldn’t have eaten it anyway. I’m a vegetarian, so I ended up eating mostly beans, tofu (which is also beans, now that I think about it), and vegetables. Other things weren’t as filling per calorie as those foods.

It still astounds me that some people have to actively manage their food so they dont get fat.
