And hydrocut is messing with things you cnat start to understand... like you thyroid... so get off them. and eat enough that your not starving your self and pick up a sport
You are not eating enough calories for your body. 150 pounds body weight should be eating (depending on your age and activity) around 2500 calories to maintain weight. Reducing to 1200-1500 calories should be fine, but going under 1000 calories will not help you lose weight, but tell your body you are starving and you will lose nothing. Good luck
