Hi and welcome
@amygirl
How confident are you and your docs that you are T1 or T2?
The reason I ask is that the information
@Tannith posted above is specifically aimed at weight loss for type 2 diabetics, and won't reverse T1.
As a T1, any weight loss regime is likely to be helpful, but you would be better listening to the experiences of other T1s.
If you are a T2 then you may well benefit following T2 information, since that is usually extreme low cal options (such as given above by Tannith) or low carb options (which may not be helpful when you are still adjusting and learning medication management.
If you have a read of the forum, you will likely see a number of people advising not to make drastic changes in diet at the same time as adjusting to new medication.
Hope that helps.
Edited to add:
The water may be further muddied because you have been prescribed ozempic semaglitide, which I have just googled, and it looks like that drug is one given to T2s, and is not given to T1s, who are usually started straight onto insulin.
May I suggest that you go back to your doc and get clarification as to which Type of Diabetes you have?
It will make a big difference in the future for both medication and dietary choices, and can be verified by lab tests. Please don't assume that a doc or nurse who announces that you are T1 or T2 because of how you look, or your age, has made the correct diagnosis.
