I don't usually go on package holidays, but I have been on a few all-inclusive and adventure treks. I did find it difficult when I was abroad in Thailand to eat while I was trekking, but I generally had noodles and rice with vegetables.
I think it's always best to ask how they can accommodate you and then maybe specify what food you can eat so they can provide it. My guides were great in Thailand and let me go shopping for food with them so I could pick what I wanted.
