I've said I'd ask this question on here for a friend of mine. She has a severely autistic son whose sleep is terrible - she rarely gets more than 3 hours sleep a night and even that not always in one stretch. He is very challenging indeed, so her stress levels are high.
She has been going to Slimming World for 5 weeks in an attempt to lose some weight. Despite sticking to the diet absolutely rigidly she hasn't lost any weight at all. She runs 17 miles a week (and has always done so) so is pretty fit.
I was wondering whether her metabolism has been wrecked by her lifestyle - the sleep deprivation and stress - and whether this would affect weight loss? Has anyone on here experienced the same thing? She is really depressed about it and she really doesn't need an extra source of depression.
Oh and she's young as well - early 30s - so it's not middle aged spread/ hormones like me!
