Two months now of dedicated diet and exercise and I am the same weight as when I started. I have tried TDEE eating, 5:2 IF eating. I have tried high impact heavy weight training, I have tried HIIT cardio, I have tried the opposite of these. I have tried it all and the weight isn't moving. I am near despair. I am still obese, still 65 lbs overweight.

Don't know what to do.

Are you going to a personal trainer? I find mine pushes me past what I think I can do exercise wise. For me, I can't do many carbs if I want to be losing. My carb level during losing is 20 grams or less a day and those 20 grams were always eaten before my workout. Now, I have to keep it to about 50 grams a day to maintain my weight. Carbs play a big role in my body and the carbs I do eat come mainly from veggies. Also, you may want to check to see if you have any DXA scans in your area - they are a great way to figure out your entire body composition and can give you a better idea of your BMR. Here is some info from the place where I went: http://washington-institute.com/body-composition/

It breaks my heart that you are stuck where you are in your weight loss journey. It doesn't seem fair at all. I know you have totally struggled for a really long time. have you had your thyroid checked. Something is definitely not right. You are very diligent and are doing the right things that should contribute to weight loss.....I also know that stress causes our bodies to release cortisol and you have been exercising a ton so the cortisol levels should be down. I would talk to your doctor about this. I am sending healing energy your way to help alleviate some of the symptoms.
