There are only three things in what we eat; carbohydrates, protein and fat*. Each of the three have a different effect on the glucose level in our blood (Blood Sugar level). The effect is shown in the following graph.
- Carbs spike blood sugars to high levels for a short time.
- Proteins don’t spike blood sugar as high but they are around for a longer time.
- Fat has the least amount of spike to blood sugar but they have a very long active time.
The curve shows why LCHF works for most people. If you reduce eating carbs and replace them with fat you greatly lower your glucose load and your insulin in the process.
*There is a 4th thing – alcohol. The body burns alcohol quite nicely. In fact, it burns alcohol before anything else (sorta).
