I started investigated our protein needs when my thyroid levels were very low. I then realised my protein levels were also low. The thyroid does go in slow mode if it feels you are going through a famine - here starving yourself of proteins. As soon as my protein levels reached a 'normal' level, my thyroid level also reached a 'normal' level. There was never any problem with the thyroid. Always get your GP to check all levels together to make sense of what is happening to your body.
Based on our 50+ years old bones living on the land where there is no strenuous activity on a daily basis:
Each day we keep the body moving whether to handle livestock, or work on the vegetable garden or maintain the infrastructure.

What works for us
is: 1g of protein per kilogram of our body weight. So if I weigh 50kg, I need 50g of protein each day.
Each food brings a different quantity of protein. This may be displayed on the pack or you may need to refer to other sources such as:
>> access Book: What Food is That and How Healthy is It?
: On a tin of tuna chunks in springwater
protein per 100g is listed as: 25.8g
So if that was the only food I was eating on a given day, I would need roughly 200g of this drained tuna to satisfy my daily requirement.
Obviously we do not get fanatical about it. But early on when we changed our diet, we realised how low our protein intake was.
This seems to work for us.
Try and find out what works for you given your weight, activity level, and the type of protein you eat, and if in any doubt, work with your medical team.
