For a good while I was doing 3 day fasts drinking loads of water and coffee (wouldn't recommend the coffee but it helped me,) then 3 days or more eating mostly green veg and meat and drinking tard cum. Doing that as well as cutting sugar out of my diet completely as much as possible lead to me losing quite a bit of weight in a relatively short time, it was very rewarding. My general mood improved significantly, I felt like I had more energy and I started sleeping a lot better. 10/10 would recommend.
Breakfast is a scam, your body doesn't even start processing nutrients efficiently until hours after you wake up, breakfast is a fucking meme, only cereal companies think breakfast is "the most important meal of the day." There is NOTHING to back it up. Eat light during the day, don't snack, and eat a hefty dinner that isn't full of garbage.
