I've been eating low-carb for just over three years now (roughly 50 grams of carbs a day) after a diagnosis of high blood sugar. I've also been working out, doing a variety of weights machines plus 40 minutes of cardio, three times a week. I'm male and in my 40s.
It's worked well in terms of keeping my blood sugar down, as I've stayed out of the pre-diabetic range ever since. In terms of fitness, everything was fine for the first couple of years. I wasn't building loads of muscle, but I didn't expect to because I wasn't power-lifting or anything. I had the sort of look you'd expect for someone doing that kind of workout: slim, with reasonable muscle tone.
Then about a year ago, I noticed I was starting to put on a bit of weight round the middle, and that my upper back was starting to go soft. My arms were getting thin and stringy. I was clearly losing muscle mass, and putting on flab. I tried loading up on "good" carbs before working out (lentils, chickpeas, etc). Tried changing my workout around. Tried drinking protein shakes after exercise. Tried everything that everyone suggested, and I'm still doing most of those things, but it made no difference and this kept getting worse and worse.
So now, here I am with a body that looks like I've never been in a gym in my life. Generally skinny with no muscle, but with huge handfuls of flab on my back (upper and lower), backside, thighs, chest etc. My face is horribly gaunt, but I also have a double chin and my jawline is suddenly sagging like an old man's. It's the worst of all worlds. As well as this, my arms and legs ache 24 hours a day, I have no energy at all and I feel totally fatigued after working out (I used to feel quite energised after exercising, on an endorphin high).
I've had a lot of medical tests which were all negative. My diet is high in protein and good fats, but low-carb, and this is the only thing that seems to be left as the cause of this. (When I used to eat high-carb I found it very easy to bulk up in the gym, and I wasn't that much younger then.) I can't stop eating low-carb because of my blood sugar, so I need to find a way to reverse this. Is anyone familiar with the problem, and if so, what can I do?
