I describe it as "appetite calming." Not sure how else to put it. I used to have a low grade constant craving for food. I wasn't obese but the weight had crept up. Losing weight was impossible. I had high blood sugar, blood pressure, and cholesterol. (Now on meds for all those things and they are under control.) Immediately after going on metformin my appetite calmed. Slowly, over the next year, I lost 25 pounds. I did not try to diet. My BMI is now 23.7. After a few months I started weight training. I changed my diet to lower carbs. I haven't lowered my HbA1c into a totally comfortable level (it is 5.6 and 5.7 and above is prediabetic). But I am better. But before any of those changes, just the Metformin alone calmed my appetite. I can go hours without thinking about food. I am just less concerned. I feel normal. Just as a data point, the last time I got Covid, it was quite mild. It's at least possible that the better metabolic health and weight loss had an impact.
