How many fat grams should i eat daily? i am trying to lose weight post my metabolic shutdown when my tsh was too high.

No need to count: I'm glad your thyroid disease was discovered and I trust you're taking thyroid replacement as needed. Nobody counts calories or grams of fat for long without losing interest, and since I don't know how much you exercise, I don't know your calorie needs. Eat sensibly, talk with your physician or dietician if you like, be comfortable with being a little hungry much of the day, and refocus on fitness
