First time eating food

Hi I'm starting to eat proper food now wow it's strange waste ov time eating out as I'm not joking I only got about 6 small spoons full then I could feel my tummy rumbling so stopped had salmon and mash I had to put some on my wife's plate so I did not look ? bad as the food was perfect ? think I might stay in for a while until I can at least eat abit more ? But feel good to be trying once again it's wird coz my nut told me what to eat half plate Protein and rest carbs /veg ? But not how much ? She said you will no when to stop lol ? and to be fair she's right
