Since you’re already starving yourself—sometimes when I want to loose weight, I go on a “5 bites diet”. Basically skip breakfast, have 5 bites of food for lunch, 5 bites of food for dinner, and two 1 bite snacks. Following a diet like that might be easier than fasting all day, idk everybody’s different.
Also, I’m sure you already know this, but alcohol has a lot of empty calories
