Being in your late 40's is when perimenopause starts... night sweats, hot flashes, irregular periods. Believe me you are on the right diet. I was trying to be vegetarian in my 40's and not getting enough protein. I ended up putting on 50 lbs total. I was a chub. Now I'm very close to my goal weight and its all because of low carb. It's the only diet that works for me and I have to live like this forever. Can't go off it. But who would wan to? It's so nice to be able to have a pan fried steak with the pan fat poured all over it.. (mushrooms too) and nice vegetable sides. So much better than low fat cardboard crap right?
