Glycemic index and Keto What is the glycemic index (GI)?

The glycemic index is a scale that measures how quickly and how much a carbohydrate-containing food raises blood sugar levels. Foods with a high GI value (70 or above) raise blood sugar levels quickly and drastically, while those with a low GI value (55 or less) raise blood sugar levels more slowly and steadily.

How does the glycemic index affect the keto diet?
The keto diet emphasizes low-carb, high-fat foods to achieve ketosis, a metabolic state where the body burns fat for fuel instead of carbohydrates. Foods with a high GI value can spike blood sugar levels and interfere with ketosis, making it important for those following the keto diet to choose low-GI foods.

What are some examples of low-GI foods?
Examples of low-GI foods include non-starchy vegetables (e.g., leafy greens, broccoli, cauliflower), nuts and seeds, berries, and low-sugar fruits such as avocado and coconut.

Can I eat high-GI foods on the keto diet?
While it is generally recommended to avoid high-GI foods on the keto diet, small amounts of high-GI foods may be incorporated as long as they are balanced with other low-GI foods and fit within the overall daily carb limit.

Is the glycemic index the only factor to consider on the keto diet?
No, the glycemic index is one of several factors to consider on the keto diet. Other important factors include total carbohydrate intake, net carbs (total carbs minus fiber), and overall nutrient balance.

Should I always choose low-GI foods on the keto diet?
Not necessarily. While low-GI foods are generally preferred on the keto diet, it is important to also consider other factors such as nutrient density, fiber content, and overall food quality.

Can the keto diet improve blood sugar levels?
Yes, the keto diet may improve blood sugar levels by reducing carbohydrate intake and promoting the use of fat for fuel. However, individuals with diabetes or other health conditions should consult with a healthcare professional before starting the keto diet.
