Which diets can you avoid counting calories?

Keto, Intermittent fasting, Carnivore, Atkins etc can all be used for weightloss; all work by restricting calories, you don't necessarily have to count as the restrictions imposed often mean you're under maintenance.

Pasta, vegetables, meats, cheese, olive oil.

That's a diet were you'd certainly need to be tracking. It's also a good option for bulking.

As a general rule, any diet that is inherently conducive to bulking too, should be tracked for weightless.

Agree with those options. There are others that naturally lead to a deficit but are either not great (low fat) or ridicules (Lemon, Cayenne, Honey Diet - FFS)

It's a form of Intermittent fasting. A bit of an extreme one (4/20). Assume 8 hours sleep, you only have a 4 hour window to eat. You'd probably fit two meals in there. And the second would be larger than normal, not so larges to make up for 2 skipped meals.

A more reason able form is 8/16. Where you don't eat for 8 hours before or after bed. Can be 8 before, 8 after, or 4 & 4.

Obvious if you are getting less than 8 hours sleep you increase the fasting period.
