I am stuck, no actually im going up as of this am. Im hitting my calories at 1300 per day and I do 60 minutes of Les Mills Pump or Les Mill Combat 6x a week. I think some will say Im eating too little. IM STUFFED at what Im eating. Im 45 yr olf female, 5 feet 0, desk job but active all other times. I get 4 meals a day in. the scale has not budged and Im so down on myself now. I put 110 percent effort into all my workouts and someone suggested I cut back...WHAT! my whole life I have heard eat less move more. I have been faithfully exercising for 3 years never missing 2 days in a row.

what is too much cortisol too? I have heard that thrown around lately at my gym in regards to my lack of loss.???

oh, I weigh 131 as of today and just 8 short months ago I was 118. Im at such a loss. I actually let the scale make me cry this morning. so I put it in the closet. My size has shrunk though, never before could I get into a 4 but I can now. Which is so odd since I weigh more.
