@maxelly You're right, I hate it when people say things have been proven and then offer no evidence, but in my defence I haven't read these articles in 5 years so have no easy way of finding them again at short notice. I, however, did not talk about carbs like they're 'some kind of poison'. I'm advocating the original poster to try a low carb diet, not a no carb diet.
Like I say, I can't at this moment provide the articles I read or the videos I watched, but a quick google will reveal several sources around the subject, here's one. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4204795/
You don't even need a scientist to tell you that after you eat a really high carb meal or snack, especially if it's mainly simple carbs, you have a short energy spike and then you feel weak and hungry again in a way you don't with either fatty or high protein foods.
The info I read basically indicated that while you can indeed lose weight on a high carb or low carb diet if you restrict your calories to be in a deficit, a low carb diet will mean you're not hungry much, but a high carb diet (like most people have today) will result in you being hungry before meal times and prone to snacking, hence why people are bigger now. And that's not to mention the other health problems caused by high carb, such as diabetes.
I've lost a significant amount of weight by continuing an average modern diet but calorie counting, and I've lost weight by reducing the amount of carbs and not bothering to calorie count. One was really hard all the way through and why I eventually put the weight back on, the other was hard for a few months and then easy, and we've both kept the weight off. We just don't feel hungry like we used to, that's what the research I read said would happen, and that's what did happen. I'm not trying to nay-say any other diet people wish to follow. If something works for you, keep doing it.
