Need advice

Hi everyone, I’ve been exercising regularly at home using only my body weight, and I’m also trying to do intermittent fasting—although I occasionally break it in the evenings, but not often. Around 12-1 pm I eat oatmeal with yogurt and two eggs, and in the evenings I have a normal home-cooked meal. I don’t eat junk food or sweets; after noon I usually snack on things like nuts or fruit. Despite all this, my weight always stays around 83–84 kg (I’m 175 cm tall) and I just can’t seem to get below 80 kg. I’d really appreciate any advice on what I might be doing wrong or what I can adjust.
