I recently started running. After it, I could feel extremely hungry like the gastric acid is burning my stomach. What could I eat to stop it and not gain too much calories ?

I don't work out

The dumbbells xD
...

Shawarma There's beef for protein and the vegies for vitamins.

After working out you need to eat something rich in protein, so get that...from your boyfriend

Or just drink a protein shake many people go for that option.

Maccas

I drink a protein shake. Having protein after running or working out will most likely fix that hunger you get afterwards.
I use the vanilla muscle milk powder (because the pre-made ones are lowkey disgusting)

water and air

yes, after working out, my energy is almost zero and i need to eat something to boost my energy back

A protein bar, or cereal usually.

Or you could try those cliff builder bars after a workout

I workout first thing in the morning and then I have an Asparagus, Apple and lemon smoothie with flaxseed followed by porridge oats and 2 boiled eggs.

protein.

beetroot bavarois with beetroot confit and puffed quinoa

protein shake & siomai.

Steroids

pregnant waterbug soup from my favourite trattoria

I usually eat the most after I do and I know it's wrong but I can't help it

OT: I only drink the first hour, and eat oats after that.
