If you eat less calories than you burn, you will lose weight. That’s just science - that works universally. I don’t really think these fad diets are a good way to view health. There’s a lot more to a healthy diet than just losing weight - your body needs carbohydrates, in fact carbs should be your primary source of calories and foregoing all carbs isn’t a healthy way to lose weight.
In my 30s I’ve learned that alcohol is a pretty dangerous and not terribly fun drug.
I’ll still drink maybe once a week (but that is a beer or 2, or maybe a bottle of wine).
For the most part, ketamine is a safer and more fun substitute
