Fat slows down the absorption of carbohydrates from your stomach, which can mean that your insulin may hit your bloodstream before the carbohydrate has been fully absorbed. Glucose levels could fall after eating and then rise considerably much later on, even throughout the night for meals such as pizza, fish and chips, rich creamy pasta or curries. 

Don’t be surprised if you need larger than usually calculated doses of insulin for a high-fat meal and also for one with a lot more protein, a large portion of meat or chicken for example. And, if you do, it is a good idea to split the dose between the beginning and end of the meal. 

💡 Keep a note of when you do eat out and use your experience to remind yourself of your insulin doses for next time!
