There are alternatives. Once you get use to it, it's actually not a problem. The only issue is people who are prone to temptations. I have trained myself to seek pleasures outside of food and food to me is just a necessity, not a source of pleasure, and I don't have any internal struggle anymore and the only problem now is people who don't know me and who keep insisting that I try this or that. And, of course, the wasted time to explain my eating habits to people - 2 meals a day within 8 hours, and so on.
