If you are eating out or with friends, again, make sure you don’t arrive hungry. Most hosts or restaurants will want to provide different choices, but as in grocery stores, there will usually be more carbohydrate and sugar foods than carnivore foods.
I often eat some fat and protein before I arrive so I can be sure I won’t be hungry during the event. You can focus on the carnivore foods, if provided or offered, and avoid the rest. This way you can relax and enjoy the company and the conversation.
As a former restaurant owner, I can attest that it is always easier for the kitchen to remove an ingredient from a dish than to switch out or add one. Because of how prices are calculated, you may have accept paying the price on the menu, even without the rice or pasta.
Removing dairy is usually easy because it is added to sauces at the last minute. Some sauces contain sugar and, unfortunately, the owner, if they aren’t the chef, may not even know this, and won’t be able to tell you if it does or does not, so it is best to avoid sauces. Ordering a plain steak or fish is always safest.
