I understand that further reducing caloric intake is easier said than done. ...Read more

Can PCOS be caused by extremely low calorie diet at age of 13?(diet caused clockwise periods not to come for 6 months, until returned to norm diet)

Return to normal nutrition signals the bodies internal clock that reproduction, an optional body function, would not draw off nutrients needed for the person to survive. PCOS is an entirely different issue that can cause irregular cycles. ...Read more

Currently eating 1100 calories/day burning 350/day to lose weight from hypothyroidism. Now my sleep is disturbed due to hunger. Any suggestions?
