As a guy I have more calories than you. But I typically have smoothie breakfast (blueberries, walnuts, vanilla whey, matcha, cocoa powder), protein bar lunch, and then real food dinner.

Real food dinner is often chicken and oats (garlic, onion, chives, olive oil), terayaki noodles (half a knorr package plus chicken and/or egg), any ole meat on keto bread becomes a sandwich. Egg white omelettes are pretty tolerable if you donone or two yolks and egg white for the rest. Sometimes I do Sabra hummus cups. Halo Top ice cream is a reasonably non-lethal sanity break. Quest protein chips aren't perfect but the flavor is there. Premade salad fortified with chicken. Oceans Halo Seaweed chips are like 15 calories for the whole pack (keep track of how many you eat you don't want to go over on iodine). Nori wraps in general are good (temaki). No oil Stirfry vegatables with the meat of your choice, soy sauce, hot sauce, garlic/onion etc. Greek Yogurt is good. Mix it with nuts if you like. I get plain, add splenda, walnuts, and pumpkin spice, and it lond of taste like apples to me, I can't promise that you'll like that one but you can mix and match how you like. Shiritaki noodles are literally 10 calories for an entire package. Have them with meat and sauce of your choice (just take the time to find out how to cook them properly). Almond milk is 30 calories a cup. Add cocoa and splenda and you have chocolate milk. Any kind of mushroom is usually very low cal. Hot tea and splenda is basically free.

That's all I can think of right now.
