Im 5'1 and I weigh 19 stone 7lbs..

For a start, do this for you, and your health.

Don't set yourself a target like 5 stone in less than four months. It's barely achievable at the best of times, and allows for no setbacks at all. Instead, set yourself a target of so many days of clean eating, rather than weight loss.

PCOS will slow up weight loss, until you manage to reverse it a bit.

The good news is that PCOS shows what diet you need to be on, and that's a very low carb one. To control PCOS, you need to control insulin, which means cutting out all the white carbs (sugar, bread, pasta, rice, potatoes, cereals) and all forms of processed fat and ready meal.

Base meals on oily fish, eggs, fresh meat and chicken, lots and lots of green vegetables, some dairy, olive oil, nuts, small amounts of whole fruit and wholegrains. Eating this way should give you the best results.

Eat when you are hungry. Don't eat unless you are hungry. The nice thing about food like meat and eggs and vegetables is that you don't binge on them. No-one ever eats more eggs than they want, just because they've had a row with their mother.

Combine this with increasing activity as much as possible. Walk lots, climb stairs, ride a bike rather then driving, and join a gym and do some strength work.

Set yourself fitness targets rather than weight loss targets. See how long it takes you to walk a mile, then see how long it takes you to reduce that time. See how many bodyweight squats and press-ups you can do, then work to increase this. See how far you can cycle in half an hour.

Lifestyle: try turning off your television. It's amazing how much of your life a tv can suck up, and while you are watching tv, it's easy to eat and eat and eat.
