How do you react when someone offers you food you want but "shouldn't" have?

Edit: not even worth it to call people out. Carry on.

aside from food allergies, there are no foods i 'SHOULDNT' eat.

i eat what i want. i had a hot fudge brownie sundae the other day for dinner.

it was goooooood.

Question 1: How do you react when someone offers you food you want but "shouldn't" have?
Answer: There aren't any foods I shouldn't have. There may be foods I don't have room for and/or also don't want and for that I do a simple no, thanks.

Question2: Do you feel like they're sabotaging your diet?
Answer: Nope, the only real person that can sabotage my diet is me. I have control with what I put in my mouth. Saying no is always an option.

Question 3: Do you say no and feel guilty?
Answer: Not at all. Why feel guilty? If I say no, it's for a reason. There isn't anything to feel guilty about.

Question 4: Do you say YES and feel guilty?
Answer: Nope, similar to the above answer, if I say yes it's because I want it or have room for it or both. There is no reason to feel guilty about anything because I made the choice and I made it for a reason.

I usually have it haha I'll just work harder at the gym

I usually tell them no thank you.
Some I explain why. But, this has gone on for sometime because My body rejects food on a whim sometimes. So, I explain that I just can't eat certain foods because it makes me sick.
Most people understand it that way.
Others will try to make you feel bad for not eating what they bought. ( I have one old man whom trys to because he buys donuts, pastries, etc.) But, it helps if they are not freshly made or if something doesn't taste right.

... 9times out of 10 this be me...

As others have said, there's no such thing as a bad food, just bad diets.

If your diet is pretty good, most of the time, and your general trend is the direction you want, then no individual food or choice will have notable consequences. My personal anecdotal "proof" of this is that I've successfully lost weight but consumed cake, ice cream, pizza, burgers, etc. all along the way; I just don't eat them all the time.

To answer your question, I often accept the food that's offered to me because I'm pretty good at staying within my dietary boundaries for the most part. Other times, like today, I passed on a doughnut because it didn't look quite good enough to justify the extra calories. It was just some regular ol' glazed whatever. For a Boston Creme though, say from Dunkin Donuts, I pretty much always feel it's worth the calories (unless the punk employee puts it upside down in the bag and I lose a lot of the chocolate icing that sticks to the paper).

What were we talking about? Oh right, I generally accept if I've been "good" lately (sticking to my diet) and decline if I've already deviated a good bit lately. That kind of approach can take you very far, as it's balanced and works for the long term.

I can decline it from a person. It's harder for me as a closet eater to decline cookies in the breakroom. Yesterday I got one. I ate one bite and threw the rest into the trash. It was a victory.
