OP thinks they eat food, it all leaves their body, then they grow bigger due to photosynthesis

Even photosynthesis uses elements extracted from the soil. Photosynthesis doesn't create plant structures out of nothing.

IIRC, a lot of the plant is just water, and the solid stuff is mostly carbon dioxide derived compounds. Only ≈3% of the plant's weight is from minerals extracted from the soil.

Animals lose weight primarily by breathing out CO2, plants gain weight breathing in CO2. Basically similar in principle, but not basically the same.

Yeah for some stupid reason I completely skipped the “dioxide” part. I read carbon derived compounds. Thanx for the correction!
