Very true. Lots of misinformation too. There are many schools of thought, and I'm not sure that all have science or research behind them, but it's possible. I think the key thing is this: Is what you're doing working for you? If it does for awhile, and stops working, you may need to make some adjustments. In my case, it was macros. Up to a point, I am able to eat keto ratios that were mostly fat (by calories) and lower protein. After a certain point, I did see that I had to limit fat and make sure that my ratios were higher protein by calories. And calories do count, I believe. If I wanted to continue making progress, I had to lower the fat, increase the protein, and make sure I was still eating at a deficit.

The other thing I've learned is that i don't try to find "low carb recipes" especially desserts and treats. I basically eat some variation of meat, some fibrous vegetables for most meals; eggs in some kind of fashion and often some meat for breakfast. I think it works.
