> my research indicated that calorie counting is a myth
Given that calorie counting (or rather, being in a caloric deficit) emphatically does work[1] (it's roughly just a matter of thermodynamics), I would (respectfully) argue that your research was insufficient.
It is true that the vast majority of people underestimate their calorie input, and there are some special cases (such as diabetics) where calorie counting doesn't give you the results you expect (insulin resistance increases the amount of energy required to "burn" a certain amount of fat because insulin is used in fat expenditure). A disturbing amount of weight-loss studies depend on subjects to self-report the amount of calories consumed -- which almost always invalidates the conclusion (people always underestimate their calorie consumption, doubly so when they've just started a diet!).
However, for the vast majority of people, the standard formulas for total daily energy expenditure[2] are more than accurate enough for accurate weight loss (especially for people who are >15% body fat -- once you get really lean there are other considerations when trying to reduce body fat). They definitely aren't perfect, but they're usually accurate to around ~5-10% (more than enough to get a good idea of how many calories you should be consuming, and how much of a deficit you need to be in in order to lose a certain amount of fat at a certain rate).
> Certainly, I always struggled with a calorie-restricted diet, so I knew that if I always felt hungry, anything I did wouldn't work.
Did you change what kinds of food you ate when eating with caloric restrictions? Usually you want to eat very low-caloric-density foods like broccoli (your body's "fullness" reaction is determined by the volume of food you eat, not the nutritional content). A common mistake is that people will try to eat the same types of food (high-caloric-density), just less of it -- this is a recipe for disaster because it will lead to inevitable hunger tautologically (not to mention most high-caloric-density food has lots of sugar which triggers an insulin response -- causing more hunger after you've eaten it).
The primary reason why people lose weight when doing intermittent fasting is because they consume less calories as a result (you would have to actively stuff your face to get the same amount of calories in 8 hours). Have you tried counting calories now that you intermittently fast, and compared it to how many calories you ate beforehand? You might be surprised to find that's where the real change lies.
All of that being said, feel free to do whatever works for you. Personally, I found it easier to count calories and eat higher-density food. Then again, I usually skip breakfast so you could argue that I also intermittently fast.
> I know it sounds crazy that you can eat as much as you like and still loose weight but it happened.
I very strongly doubt this is true, purely due to thermodynamics. If you ate 10k calories every day (with intermittent fasting) you would gain weight (if you don't believe me, try it for a month and see what happens -- you should gain a few kilos a week depending on your existing weight). I would guess it's more likely that you simply felt that you ate more (but actually started eating less). Do you weigh your portions of food (most people are awful at estimating even how much mass of food they eat, let alone the caloric content)?

- icu 7y agoIt sounds like you know a lot more about this stuff than me. It is my fault in so much as I should have used more precise language. What I meant by 'calorie counting is a myth' is that a calorie reduction diet is a myth. Sorry for the confusion. Also, I admit, I could be wrong. I'm going off of the research I have done. That said, there is a lot of stuff happening in our body with regards to our food intake that I had no idea about. Insulin, ghrelin, leptin, and of course, testosterone for a man, is extremely important. Even limiting xenoestrogens as a man is extremely important. Also, people seem to forget somehow that your body can excrete calories. I agree with you about the problem of "people will try to eat the same types of food (high-caloric-density), just less of it". In the past, I tried a vegetarian, calorie-restricted diet, and I just felt hungry all the time. It wasn't a one for one diet to what I eat now, but it about the same. In terms of why intermittent fasting works, I don't know for sure, but from what I have read, your body's metabolism doesn't crash because your feeding window controls the ghrelin in your system. With your metabolism maintained, and by only drinking water during the 16-hour fast period, your body is forced to consume your fat stores for energy. Having said all that, you could be right... perhaps I just consumed fewer calories as the plant-based diet was just less calorie-dense. The volume of food may have made it feel like I was eating more when I wasn't. Honestly, I just don't know for sure.
- BurningFrog 7y agoCalorie counting works, when someone else is controlling your food supply. When I control my food supply, my hunger will almost always override the cold math of the calories. It's a bit like how abstinence can prevent pregnancies, so you don't need condoms or pills. It's of course true in a technical sense, but real world people aren't strong enough to remain abstinent.

- cyphar 7y agoUnfortunately, every lifestyle change requires hard work. You can't learn to dance or play an instrument without putting in the hours. Same thing applies to losing weight and getting healthy. Sure, there are "tricks" (such as eating lots more low-calorie-dense food such as broccoli or cucumbers to quell hunger pangs) but those are just tools that still require hard work to apply.
