I just measured myself on the Tanita body composition machine after a 10 day boozing/bucks party holiday.
Before I went on holiday my body fat had been steadily reducing from 21 down to 15 over a few months.
After the boozing, the machine told me I had not gained or lost any weight, but instead lost 5 kilos of muscle... meaning I had replaced it with 5 kilos of fat...
Seems pretty unlikely no???
Is it even possible to lose 5 kilos of muscle in 10 days?
