Do you eat the same amount of food

Yesterday I got my first shot of mounjaro…

I weight 59 kilos

My height is 170 cm

I’m not looking for weight loss primarily, my endocrinologist gave me the medicine because I have insulin resistance.

Today I had a Chobani yougurt for breakfast 20 grams of protein, then I had for lunch 3 salmon (130grams) tacos (tortillas 1/3 Delgaditas). And I’m feeling yuck, I didn’t enjoy my food and I wanted to stop at the first taco.

I don’t know if that is normal, should I stop eating when I feel full, ever though it’s pretty few food?
