Thank you for your advice. If I may ask, how long did you had to wait before re-attending the assessment centre? Did you had to all of those tests again or was it just the BMI check?
I think I was about 92kg (which gave me a BMI of ~30) when I attended ADSC. Much like yourself, I had been cutting down from a starting weight of 106kg (I played rugby as a prop forward and was hitting the weights hard at the time)
I had to wait about 4 months for another ADSC slot (this was in 2010 so recruitment was in full swing with Afghanistan being a big draw for the army) and I was made to re-do the full ADSC.
I made myself quite ill in the lead up to ADSC trying to drop weight too quickly, so I'd advise against it (I had got it into my head to cut caffeine in the few days prior to the date to assist with my blood pressure as well and ended up with flu-like symptoms with the come down not realising how addicted my body was to tea/ coffee)
