Hi
They seem to be linking gut flora with a whole host of things now. I watched a program about those with good flora kept naturally slim and to test this they compared twins and their diets, one twin was overweight with bad flora and the slim one had good flora. There must be other factors involved such as metabolism but then does a good metabolism come back to gut flora and liver function?!
It's really interesting! As you know I had to change my diet totally due to the gallstones but that change has meant I lost weight immediately (had been trying for ages and nothing happening!), improved digestion although I can't say that the phases of night sweats have gone even though I'm on hrt.
Eat lots of pre-biotic foods to encourage good gut bacteria, I've also found a daily probiotic helps as well.
