Counting calories may not be correct and useful advice for most people. It ignores what the calories do in your body. As an absurd example, sand is very calorically dense, and you'll lose a lot of weight and then die if it's all you eat. Telling people they "eat too much" is usually ineffective, it just makes people feel bad that they can't tolerate hunger.
Ketosis will work (it's very low carb, not zero carb). You (as in you personally) won't be able to do it, you likely lack the willpower, and if you're social, it's difficult to do in a social setting, especially without taking a deep dive into the science to help understand the how and the why.
