Nikki do you think your body might be holding onto things because you aren't eating enough calories?
Whats you MBR? If you drop too far below your MBR, your body hits starvation?
These are my details, id work yours out but not sure on your height age etc.
My MBR (Metabolic Basal Rate) is 1938 kcals. Meaning I need to eat this daily in order for my body to function.
You then use Harris Benedict equation to work out your DCN (daily calorific needs). What your body needs to function when you take daily activity into account. I would say that I am sedetary, so I multiple my MBR x 1.2 = 2326 kcals daily.
I need to eat 2326 kcals daily to maintain my weight.
But we all know that you need a deficit of 1000 kcals daily to lose 2lbs a week. So my daily kcals then becomes 1326.
My new daily calorie intake is 68% of my MBR. I know that if your BMI is higher than 40, you can go as low as 60% of your MBR before you start hitting starvation.
I can't remember what it is for a healthy BMI, but I'm sure it is 75-80% of your BMR and I would bet that you are going below that?
Maybe thats why you are hitting a brick wall?! Just a thought.
