I'm not hungry and very thirsty? Is that ok if dieting>'

Malnutrician. You don't mention your wt. If you are eating mostly protein, you maybe dehydrating which is a strain on your kidneys. When someone diets for a long time and looses appetite, I worry about anorexia which can lead to loss of hunger, malnutrician and multiple medical problems. Consult with an internist to discuss your situation and advise appropriate diet program.
