Your consideration of something as a special treat doesn't mandate everyone else to agree. And lots of things are addicting, including tea. That property, without other qualifiers, is irrelevant. Also, we don't know what kind of take-out OP's family was eating. It could have been take-out salads (given OP's comment, it probably wasn't, but still). NO ONE on any kind of diet or exercise plan is entitled to special treatment because of it. And I say this as a runner. I don't get scheduled time off work to go run, I'm expected to find my own time for it. If my boss wants me to taste-test a new dessert, the only person responsible for me saying yes or no to that is me. OP has chosen to make a lifestyle change. That means owning it and being responsible for it themself.

I think support from your boss and support from your family are two different things though.

There certainly other qualifiers, all of the problems that junk food cause like obesity and diabetes. I think if you love someone you would want them to live longer and have a better quality of life, and want to support changes that lead to that. Tea isnt going to make you sick, its healthy for you.

of course i understand how addicting junk food is! i lost a lot of weight myself, in high school. and i had to cook ALLL my own meals and even get a job to buy my own healthy food. it can be done

The "if you love someone" street ought to run both ways and should include respecting their choices when those choices are moral neutrals. Like diet or exercise, for example. Otherwise you're (general, non-specific you, not anyone personally) in a relationship where you're expecting everyone to respect/support your decisions, but you aren't returning the favor. In which case, you need a wake-up call.
