It doesn't matter a jot whether you are skinny, near skinny or more generously proportioned, starvation has the potential to damange the metabolism.
Thank you for the advice.
A bit more info for you.
I have spinal damage at l4/l5.
I am on high doses of morphine and don't have a great deal of control down there.
For the past 20 years my gp has been trying to get my weight down.
A lot has improved since my diabetic diagnosis.
The first is my weight loss.
My first 2 weeks I was on zero carbs and I lost 5 kgs. Mostly water weight as i was always thirsty.
My constapation got worse as I lost my entire fibre input. This stabilised the following week and am regular for me again.
I have little ability to exercise but manage my 1000 steps a day.
I now have more energy since hitting ketosis. I woke up one morning and the energy levels have stayed high.
I am having fun trying new recipes.
Except for the morning spike in bgl i was level all day. This was solvef by having cream in my morning coffee.
Thank you all.
