Following a low-glycemic diet for weight loss isn't about deprivation; it's about making better choices and swapping high-glycemic foods for ones that have a lower glycemic index or glycemic load. Once you get the hang of figuring out which foods are the best choices, you can easily shop, cook, and snack the low-glycemic way.

Low-glycemic measurements

The glycemic index ranks food on a scale of 0 to 100 based on how quickly they raise blood sugar levels. Foods that raise blood sugar quickly have a higher number, whereas foods that take longer to affect blood sugar levels have a lower number. Here are the three measurement categories:

  • GI of 55 or less = low

  • GI of 56 to 69 = medium

  • GI of 70 or more = high

Choose foods that are low- to medium-glycemic to keep your blood sugar stable.

Swapping high-glycemic foods for low-glycemic foods

Replacing high-glycemic foods with low-glycemic ones is easier than you may think. The following table features some simple low-glycemic food swaps you can make.

Just because a food has a low-glycemic index doesn’t mean you can eat as much as you want.
