Keto diet involves eating low carbs, moderate proteins and high fats


  1. Keto diet is popular for its quick weight loss properties
  2. It may be beneficial for people with type 2 diabetes
  3. People with type 2 diabetes need to consume fewer carbs

Keto diet is a popular approach for weight loss. It is a high-fat, moderate-protein and low-carb diet. It forces the body to burn fats instead of carbohydrates. People with diabetes are suggested to eat fewer carbs. They are recommended to eat complex carbohydrate like like brown rice, oatmeal, beans and lentils, and avoid simple carbohydrates like bread, sugar and pasta. Simple carbs result in a rapid blood sugar spike. Complex carbs are healthier and do not result in rapid increase in blood sugar levels.

Let's look at the pros and cons of keto diet for a person with type-2 diabetes:

Pros: The focus of keto diet on high fats and minimal carbs can influence body's blood sugar control rate. This is more crucial for people with type-2 diabetes. Lower intake of carbohydrates can help in eliminating large spikes in blood sugar, reducing the need for insulin.

2. Improve insulin sensitivity. During diabetes, body cells can resist insulin hormone which can increase blood sugar level. Keto diet can improve this insulin sensitivity.

3. Reduce your dependency on prescribed medication for blood sugar control

4. Improve good cholesterol levels without adding on to bad cholesterol

5. Benefits of keto diet can be obtained with a proper meal planning. A person with diabetes needs to plan out his/her meal to prevent adverse health outcomes.

Your diet should consist of:

1. Low-carb vegetables: Avoid vegetables which are high on starch like corns and potatoes.

2. Eggs: Eggs can be considered as an ideal food for keto diet. Apart from being an excellent source of protein and healthy fats, eggs are low in carbohydrates.

3. Healthy fat sources: Keto is a high-fat diet. Go for healthy fat sources like avocados, olives, nuts and seeds.

4. Berries: Berries can be helpful if you eat in moderation. These juicy fruits are delicious and can provide fibre, vitamins, minerals and antioxidants to the body.
