Please, as someone who went down the keto rabbit hole 10 years ago, please don't do it unless you have a medical reason, aka diabetes.
Keto is not sustainable for you and in fact for the vast majority of people, it's not inherently healthier, the reason it works as with any other elimination diet, is that you remove a bunch of highly palatable calorie dense foods.
The hard truth that no one wants to hear is that the only way to lose weight long term is to change your lifestyle to one that you can stick to for the rest of your life, that means learning to eat nice balanced meals of veggies, carbs and proteins for 80-90% of your food.

Keto is a fucking cult, get out while you can, unless you want to have diarrhea anytime you have pasta, or a beer, or anything with higher amount of carbs, your gut biome changes and you will not be able to properly digest it for a while, so no living your life and having a fun date night with your girl, it won't be fun in the evening.
I also encourage you to read Atomic Habits, it's not about weightloss, but it is really good about teaching you that small changes over a long period have big results, and that is what weight loss is, you can't rush it, it's a long process.
Also you want to consider picking up weight lifting as building and most importantly retaining muscle mass will do much more for your health than whatever keto cultist claim.
