Anyone here on Metformin?

I have polycystic ovary syndrome and as a result grew up with an insatiable appetite. I felt I was starving on 2200 calories. According to the NHS website I'm meamt to eat 1900-2400 per day. Now that I've been taking metformin regularly I feel stuffed on 1500 calories. I feel almost as though 1500 calories is me force feeding myself as I feel full all day eating that little. Do you think its OK to go along eating this little if I just don't feel hungry? I'm not loosing weight drastically quickly?

My personal opinion, Natz, is that you should listen to your body and eat to satiety, not full to bursting. However, I'm not a medical professional, so maybe you could have a word with your doctor, or dietician.

Just make sure that every calorie that you do consume, is nutritious. Don't fill yourself up on empty calories :)

All the best :)


Hi there!

I was diagnosed with PCOS 5 years ago. I always found I had a larger appetite that most of my friends.

I got put on metformin 2 years ago and completely lost my appetite with it. It also gave me a horrendous tummy 😭 So I decided to stop taking it.

Got to say though losing weight does help with PCOS. Every single time I lose over half a stone (when I first start a diet or healthy eating) it always kick starts the time of the month!

Maybe try speaking to your doctor and see if there is something else they could put you on that doesn't have the loss of appetite side effect.

Although we slow losers console ourselves by saying it is better to lose slowly. I don't think there are many downsides to losing fast. Just do it whichever ways suit you. You've had all the negatives from your condition, finally a positive. Just try to fit in enough protein, a little oil, some dairy and as many veges as you can face. I've been losing happily on around 800kcal recently and had to cut down on my veges as I could not eat the bulk, If it works for us, it works! Happy weight losing!

Medical matters need to be discussed with a health professional. Ensure that the food that you're eating provides all of the nutrients you need. That said, your hormones may be normalising, allowing you to use your body's energy reserves, freeing you from the constant hunger you've grown up with.
