#1. You should consult your doctor.
I don't have any personal experience with this but according to my female friends water retention is a common problem - and they are not vegan. They are post menopausal.
However, Water retention is sometimes a symptom of something more serious. So you should see your doctor. When you ask your doctor about this you should ask for a the standard battery of blood tests that test for nutritional deficiencies.
In the meantime I think you should join CronOmeter. Its free. There is a learning curve but after about a week it should only take you total 5 minutes a day.
It's a nutrient tracker and it does all the research and math for you. It's on the Web and also there is an app. There are paid versions but the standard version is free.
You just plug in what you eat and it does the rest. You may have an issue with the absorption of things - but knowing that you are or aren't ingesting the right amounts is a big step. You can even plug in your supplements.
Sounds like you eat a lot of the same stuff a day. So you can combine the ingredients into a "recipe". That saves a lot of time. And/or you can just use the copy and paste functions from day one to day two.
It's pretty easy. the ChronOmeter website has a great FAQ, and a search function for questions, and a forum. Or you can even send me a PM.
Also on YouTube, CronOmeter and its friends have a lot of good instrucional videos. I haven't watched any in long time but just now I took a gander. A few years back CronOmeter made some improvements which made many of the videos out of date. And they took down all their old ones. from my perusal - there are lots of new ones. I noticed a lot of them are from CronOmeter themselves, including a great list of shorts.
You don't have to use CronOmeter for the rest of your life. Just till you get things figured out and then maybe every time you make changes to your diet.
One nutrient deficiency that can cause water retention is Magnesium. I still struggle with getting adequate magnesium (and potassium). But have your doctor test for those two minerals, too. Magnesium and potassium can be toxic so I would ask your doctor before starting to supplement those as well. I started taking a small amount of magnesium a day.
The most common mistake most new vegans make is not eating enough calories. Part of the cause of this is that plant based food is much more bulky than animal derived foods. So you literally have to eat more.
Typically if you are getting enough calorie you are getting enough protein. Cronometer will be able to tell you that immediately.
Women need to make sure they are getting enough Vitamin D, calcium, and iron. And all vegans need to supplement B12. An Omega 3 supplement (Especially DHA) is also a good idea.
Oh, by the way, Welcome to The Forum.
