I hate pure Keto. It is too restrictive which results in diet boredom. I rarely meet people who can do it long term. They might do it for a few months only return to their former diet.
I think the simplest method is to up protein intake from where you are at (unless it is high already) increase fats in general and lower, but not eliminate carbs. Carbs are not evil, but processed carbs might be, if eaten on their own. Still, processed carbs in moderation mixed with fats and protein are acceptable and typically don't cause ravenous hunger.
Example: Eating bread alone will cause you to want more and more of it, easily eating more than your body needs. Processed carbs do this when they are laced with sugar or have no protein and fat mixed with them.
Example 2: Having buns on your burger is totally fine, as the protein and and fat mixed with the burgers won't typically cause you to be ravenously hungry after. The carbs are processed slower.
Both examples are processed carbs, but it is how you combine them that determines your body's response to them.
Of course, before someone says "Everyone is different!" Indeed, everyone IS different. But we are more alike than we are different.
If you do any type of endurance exercise, you typically want carbs in your diet. Although there are a few people who can somehow maintain their athleticism on keto, it seems to be rare. If it works, great, but most of the time it doesn't. If you just sit around, lift weights a few times a week and no cardio, keto works great. There is very little need for dietary carbohydrates in that situation as the body will create what it needs via glucose-neogenesis.
