If you’re on a particularly restrictive low-carb diet, such as a grain-free diet or a specialized diet for a condition like celiac disease, recipes from a low-carb cookbook that isn’t aligned with your primary diet plan might cause weight gain or digestive issues. The best way to avoid this is to read through the recipes that interest you and note any ingredients that are not on your allowed list. You can remove or substitute those ingredients, avoid the recipe entirely, or make it just as it is and monitor how you feel. The key here is to observe and note any changes.
