I was going to say something similar @EZB said it better.
It concerns me when you buy boxes of Atkins treats. That is not how this is supposed to work. Even walmart has lots of cheeses, cream, cream cheeses, eggs, meats and salads available. You can make your own condiments and do not have to rely on sugared ones. Yes it is easier if you can follow a recipe but there are so many easy items to cook and grab. Also, try to get in the habit of intermittent fasting. It is a great tool because I no longer bring snacks, if there is no keto food available I do not eat and it is not a problem. So much easier
