Drink quite a bit of water most days, I'd say probably average 3L, sometimes more, sometimes less, but all I drink these days is water, and I only ever do one travel mug of decaf coffee in the morning now, so it's been decent I think.
Food wise, it's usually banana in the morning, then I fast, then when I get home I'll do like a protein mug cake, usually have white fish or chicken breast for dinner with usually 200+g of some veggies, usually broccoli or lately I've been into this stir fry mix of veggies, I just steam them, but it's like water chestnut, carrots, some greens etc.
Other than that, I snack a lot on turkey breast deli meat, cheddar cheese, some crackers here and there, a lot of times I'll just have a white fish filet for a snack that I air fry... stuff like that mostly
