I believe it to be well known that people with Pcos should have lower carbs, but that doesn't mean your dietician is wrong, we are all individuals and they are technically experts. I would say read up a bit on the reasons behind high protein or low GI diets in pcos, and give her a call, there may well be a good reason for it.
Here is something I have copied and pasted, but I thought it was quite informative.
Let us know how you get on.

Because carbohydrates are often linked to high insulin levels, women with PCOS are typically recommended to follow a low
glycemic index diet. Foods in this type of diet do not cause a quick rise and fall in blood sugar levels and therefore help to prevent elevated insulin levels. Since carbohydrates are the main culprit behind rising insulin levels, many women may be tempted to cut out carbs from their diet or follow a low carb diet, such as the Atkins diet. This is not necessary, though, and may not even be healthy as these diet sometimes contain too much saturated fat, which has been linked to
heart disease.
There is nothing wrong with having carbohydrates in your diet so long as they are the right kind of carbs. Instead of choosing starchy, processed carbs, which contribute to high insulin levels causing your blood sugar to remain low while you crave more carbs, opt for whole grain carbohydrates. Because they have more fibre in them, they take longer for your body to
turn into sugar and therefore have a low gylcemic index.
Carbs: How Much is Too Much?
It is difficult to say precisely what is the right proportion of carbohydrates for women with PCOS as each woman is different and has their own
dietary needs. Some experts, however, suggest that women that are overweight and affected by PCOS try reducing their daily carbohydrates intake to 40% of their diet. If no changes are noticed, then try reducing your daily carb intake a little more until you detect an improvement. If you become aware of any of the following changes, then it is likely that you have found the right balance of carbohydrates for you:
- You have more energy
- You have fewer cravings
- You notice some weight loss
- Your insulin levels are lower
- Your periods become more regular
However, you may not need to reduce your carbohydrate intake too much. A study at the University of Alabama in the United States found that women with PCOS that consumed a diet comprised of 43% carbohydrates had reduced insulin levels and less insulin response to carbs.
Your carbohydrate intake is not the only thing to be concerned about when it comes to losing weight, though. You will also need to be careful of the amount of calories you consume. Consuming too many calories will result in weight gain, regardless of whether the calories come from a fat, carbohydrate or protein source. Additionally, try to eat your carbs with protein or fat and avoid consuming all of your carbs at one time, which can lead to a spike in your insulin levels rather than gradually rising over the course of the day.
