Yes, muscle weighs heavy. For years I have been told hat my weight (using the silly, out-dated BMI scale) shows me as very overweight. I do not look it.
Each time I tell medic that I was a dancer in my earlier years and then very involved in sport and even as I have got old, still have those heavy weighing muscles - always I got ignored.
Recently, I have put on to an injection every four weeks, to try to 'zap' a non-malignant grown I have, which effects growth and hormones.
After the last one, I noticed that I had suddenly developed lots of loose skin around my stomach and thigh area - (where I always had strong well developed muscles). Most definitely no dieting at present as my newly discovered condition has ben a shock to me and I have been consolation eating, in between virtually weekly hospital appointments
So I weighted myself and discovered that I had lost nearly one and half stone inside a week since that injection - ALL to do with the soft tissue of muscle.
