Is there anything actually SAFE and natural to curb appetite?

I’m 27f and just recently hit that point where I realized I can’t eat whatever I want anymore and remain the same weight. I’ve just started going to the gym to mostly strength train with a little cardio but most of the stuff I’ve tried to suppress my appetite doesn’t work. For example, high protein breakfasts (eggs, turkey, Greek yogurt etc) combined with whole grains satisfies me for only like an hour or two before I feel STARVING.

I am not overweight by any means and I’ve recently started researching herbs. I already take 2 prescription meds for other things and have no interest in being on another medicine. I looked into green tea, but I’m very sensitive to caffeine. Would just one cup a day help at all? The teas that promote “weight loss” just cause diarrhea.

Is there anything safe to just curb my appetite a LITTLE? I want to start living a more natural and healthy lifestyle. I’m most interested in something I could make into a tea and sip on.
