Quaker oats

I tried once and probably not going to try again. I even try adding fruit like I saw they do it in the picture but still can't swallow it. Guess it's not for me.

Talk to your doctor about what diet is best for you. Each patient is different. As for eating oatmeal, you can eat it any time. So long as you have a strong enough craving for it. If you force yourself to eat something you're not really hungry for, you won't get any value from it. And, your body might say 'i hate you' for it.

not yet tried it for lunch.

Yes, I did. I added some banana to make it tastier.

i havent tried that for lunch, but for breakfast yes i have

It's been a while for me but I like it with chocolate. Other people I know goes on a diet with half rice to no rice. I have also heard of sweet potato and Saba banana instead of rice.

I used to live on quaker oats breakfast, lunch, and dinner. Not a fan of diets so really can't suggest you any.

I eat oatmeal most mornings for breakfast.

I think it's a healthy diet

Never eat it for lunch, but I ate that years ago for breakfast. Wasn't tasty at all. I know it's healthy but with that taste I would never eat it again.
