i usually go to costco and buy chicken, beef, eggs, cheese in bulk.. i find marinades with low carbs (and use more meat then the recipe calls for) and cook up big batches of meat for the next few days. also, i tend to eat a few slices of cucumber or a pickle with a lot of my meals just so i'm getting a little bit of veggies in my diet.. like to flavor with mustard, too.
i actually look forward to getting back into keto after carbing up these days.. get to not like the feeling of carbs digesting in me and would rather stick to all the yummy fatty foods i grew up on... minus the bread
