This comes up a lot. Despite what the latest "keto coach" sold and told you, foods are not inherently keto and non-keto.
Ketosis is a metabolic state reached when your body runs out of excess glycogen stores and then starts burning fat for fuel.
If you keep your carbohydrates under 20g per day, you are essentially ensuring that your body isn't storing glycogen and stays in a state of ketosis.
Whether that 20g comes from a big ass salad, a small portion of sweet potatoes, or a coffee with a bit of added sugar, your body will still maintain a state of ketosis.
Now, that's not to say that this is the best way to follow Keto. You'll quickly ask yourself... "Hey... Is it worth blowing my daily carb allotment on this...?" Sometimes it totally is.
That negligible amount of sugar in your bacon (the package even says 0g carbs) is not going to kick you out of ketosis. That trace amount of potato starch in your shredded cheese is not going to kick you of ketosis. The wheat flour in your salad dressing isn't going to kick you out of ketosis. Is it annoying that they're there and it cuts into your daily carb allotment? Yep, sure is. But you can still maintain a state of ketosis just fine with them.
There's a lot of pretentious dogma that often comes with Keto. It's like, if you aren't eating 100% totally clean and perfect, you're wasting your time or following everything wrong. That's not the case. We all come from different walks of life... with different food options... and different food budgets.
Make it work for you. It doesn't have to be perfect. Over time, you'll discover ways to optimize and make it work best for you.
Careful with some of those coaches too. Don't get sucked into the pyramid scheme that is exogenous ketones.
Your body can make ketones all on its own.
Sorry, but if your "business" is made by captilizing on newbies and the naive, shame on you.
Now please excuse me, I have 9g of carbs worth of fried chicken to eat.
