Loosing weight without trying and appetite has changed. don't get the hungry feeling but i still eat. no other symptoms i noticed. i had blood work done about 2 weeks ago which was all normal?

Get the app Cronometer and enter everything you eat and drink and do. Then see how you can increase calories or decrease exercise. Was thyroid checked?

Unexplained weight loss has to be thoroughly investigated and best would be to start with your primary care doc as imaging studies may be needed.

Unintended weight loss needs to be evaluated. Start with your primary care provider though you may need to consult a specialist based on the assessment by the primary care provider. Wish you good health!
