5. Pasta
We all love pasta, but pasta doesn’t love us as much as we do. A bowl of noodles can make us feel lethargic in an instant. Also, when it’s low in fiber and not consumed with sources of protein, pasta can cause a spike in your blood sugar levels. It is the same process described at no. 1 (potato chips and french fries).
According to Fine, this popular lunch choice can leave you really tired due to the surge in insulin that comes after a carb-heavy meal.
However, you can still enjoy pasta, but try to opt for a higher-fiber pasta such as lentil-based varieties, or pair your bowl of pasta with a protein source that will most definitely give you the energy you need.
