Well, actually, if you drink a high fiber substance such as flaxseed
meal stirred into warm water, it will make you feel full and not want
to eat as much.

Aroma therapy uses the scent of honeysuckle to suppress appetite.

Or eat an apple cut in half and spread with chunky peanut butter. The
apple contains pectin, which suppresses appetite and the fat and
protein in the peanut butter will help you feel full. Chew it slowly
to get the full effect.

I find that a nice whole grain, low-sodium, low-fat cracker spread with
a teaspoon of spicy hummus can stop my carvings for sweet things.

There are many herbs you can try. I will look them up for you.
