Welcome back Candi!

The Lipedema project has had summits for many years https://lipedemasummit.lipedemaproject.org . There will be a Virtual Symposium this November too.
Previous talks are still available as is Dr. Westman's diet. https://lipedemasummit.lipedemaproj...dout-134067.pdf It also is a "protein first" keto diet like Dr Naiman.

The Lipedema organization primary website has a huge Resources section. https://lipedemaproject.org/resources/ They have used a simple ketogenic diet (Dr. Westman's clinic diet, he spoke at the summit years ago and will again on Keto for Lymphatic Disorders) and there are other versions of keto with more focus on nutrients.

Agree with Kristine and others, the vegetarian diet likely led to a loss of muscle/lean body mass so more protein and other missing nutrients are needed to rebuild your muscle. This weight gain is may be part of regaining your health...Even this "high" weight that is so concerning to you is just a few pounds into the overweight BMI category. There are lists of the nutrients that can be lacking in vegetarian foods (eg protein, B12, D, Zinc, Omega 3s, etc.) ...think about replenishing those and add some resistance training. Focus on protein and nutrient dense foods...this is likely not a situation for a high-fat therapeutic keto diet or EDit Add: longer IF. 2 or 3 good meals without snacks.
