Exactly! I've done intermittent fasting for many many years, it works for me. I've told people, "You know how a workout 'hurts so good'? Learn to think that way about hunger/cravings. Consider it the same way you would consider a workout pain, as progress not punishment".
Another way to look at it that I've found effective: think of food cravings as an adversarial agent. Your body is blackmailing you: if you give me food, I'll make this craving go away. Trick is, the food you're probably craving -- chips, soda -- don't make the craving go away. They make it worse. Once you notice that you're body doesn't actually make good on its promises to make the cravings stop it's easier to not give in to its demands. And that actually makes the cravings stop. It's no different than dealing with any other bully.
You need a laundry list of nutrients, and if your body is short of any one of them, it'll crave something that might have it. If it has it in insufficient density, it won't care that it needs to also get an extra 500 Kcal along for the ride - it needs to satisfy each item on the list.
I've seen this behavior in both cats and people -- feed them better quality food, and their cravings & weight go down as the full set of nutrients is found in fewer calories.
(Different topic, also very big on intermittent fasting, ensuring that there are frequent periods where the body recovers energy from fat stores)
I noticed one study a long time ago just about flavor. Basically, rats, being fed standard rat chow, with nutrients and calories kept constant, both groups had full access to the food. Group A had one flavor, Group B had six flavors. Group B gained a lot more weight. So, merely restricting flavor choice will reduce your inclination to eat, and conversely, food engineers creating foods with lots of flavors will increase food and eating...
A few weeks ago I decided to try 8/16 IF, which basically means I don't eat past 10 pm (mornings are not a problem, I wake up late and never need breakfast). I'll usually wake up around noon, have my first meal at around 3 or 4, then have a small meal at 9 or just before 10 and that's it for the day.
This has made a very big difference. I have already lost 2 kg without even thinking about it. It helps a lot that I will eat a small meal before I'm hungry (at 9), wheras before I'd wait until 1 am when I was starving and then would eat a large meal.
It has also made compliance a breeze by just not giving me a choice. I'm unable to say "I've eaten a lot today so I shouldn't have this snack too", I would just think "eh I'll have this snack and eat less tomorrow", only for the cycle to repeat the next day. Now, if it's past 10 I don't eat anything, simple.
I definitely recommend this to anyone with compliance problems. I can also 100% relate to your hunger statement, which I learnt the last time I dieted, years ago. Being hungry just means that my body is burning fat, and I can go 30+ hours between meals without really any ill effects.
I'm a bit of a fat bastard myself and I think what I've come to realise is that for a huge segment of the population eating just works fine and they can adjust diet to tweak this or that relatively easily. For the rest (like me), my relationship with food is broken and stuff like IF or keto or whatever are patches to deal with that underlying brokenness. It always works for a while, but it always go to shit eventually.
> Certain foods, particularly those rich in sugars and fat, are potent rewards [23] that promote eating (even in the absence of an energetic requirement)
If the subjects are used to carb- and sugar-heavy diet, the hormonal spikes will be very stressful on the body.
They also mention fat-heavy foods, but I suspect they are referring to foods high on both fat+sugars, not a green salad with copious amounts of olive oil.
It's so strange. My whole life I hadn't given sodas a second thought, but that reward signal is strong. I don't think I ever want to go back.
This is what I exactly tell people. It's the only way to sustain it.
