You need to deplete the carbs and then start putting them back back in at least 4 days before you go on holiday mate. Id start loading 6 days prior.

I realistically wouldn't bother aiming for fat loss now if I was already at 10% bf

It will take at least a week to deplete add 4-5 days to put the cabs back in and you have already lost 12 days or more which leaves very little time for real fat loss anyway.

The muscles will hold several lbs more glycogen when you put the carbs back in. Having been depleted they will overcompensate for a short while giving a permanently pumped look.

Carb depletion and loading isn't for the faint hearted you will certainly feel like and look like crap until the carbs go back in.

Muscle loss shouldnt be an issue in such a short space of time. Any lost will go back on during the carb up anyway.

You have to control the carb up because once you start eating again it will be very difficult to stop.

You would probably want to put 500g of carbs back in the first few days of the the carb up and then judge it by the mirror thereafter, dropping back to about 350 for maintenance.
