Before and After comments follow:

Food

Hopefully it will never be necessary to carry more than 2-3 days of food for most of the trail. If you eat in villages, cafes, restaurants etc. perhaps not even that.
The reality was that I carried 5 days supplies at the start and was very glad of it. The maximum I carried was 6 days supplies for the last section from Çıralı to the end. A bit later in the season and more places might have been open in the early stages, but then it would have been hotter so you would need more water instead.

Water

On the other hand it would be very unwise to skimp on water.
Water was generally available at all the marked sources, and during the day I rarely carried more than a litre. Approaching a camp with uncertaian supply I would add 4 litres for overnight needs, but never carried this very far. Water will also be more accessible if you carry the required gear (see Hazards).

After carrying up to 12 litres (every third day) through the Negev desert in Israel, it was relatively easy to cope with the requirements here. That's the benefit of pushing the comfort zone out a bit from time to time.

Fuel

For fuel I will use gas canisters. These are available in both Antalya and Fethiye and apparently other towns along the way. My stove (MSR Superfly) is indifferent to which canister type (screw or click) is available.

Finding fuel in Antalya was not quite as easy as I had been lead to believe. I eventually found a good supply in a big Bauhaus (near a Decathlon store) so to be safe I took two 500g canisters. I definitely bought gas in Kaş and in Çıralı. I might also have bought some in Demre, and I certainly noted at least two outlets. All of these were screw type canisters. Decathlon in Antalya had gas by the time of my return visit.
