Just gotten diagnosed with hypothyroidism and I want to lose weight, how hard will it be? And what kind of diet should I go on?

Low fat diet. I am sorry to hear about your diagnosis for hypothyroidism. But I would suggest you take all of your hypothyroidism medication (levothyroxine) as prescribed by your physician and eat a low fat diet. You might want to talk to a dietician to help you make a good dietary plan for a healthy body weight.
