Nutrition Made Simple! - How to blunt Glucose SPIKES
Dr. Mario Kratz discusses how to manage blood sugar spikes, particularly for those with glucose intolerance or type 2 diabetes. He suggests avoiding highly glycemic carbohydrates alone, such as white toast with jam, which can cause significant spikes. Instead, he recommends consuming carbohydrates with a lower glycemic index alongside protein and fiber-rich foods. This combination slows gastric emptying and moderates blood sugar levels. Studies show that eating protein and fiber before carbohydrates can reduce blood sugar spikes by up to 50%.
Additionally, Dr. Kratz advises going for a walk after meals. Physical activity helps muscles absorb glucose independently of insulin, which is beneficial for those with insulin resistance. He emphasizes that these lifestyle changes not only manage blood sugar spikes but also improve overall nutrition and address underlying health issues like weight and insulin resistance. Increasing protein and fiber intake and engaging in regular physical activity are key strategies.
Key Points:
- Avoid eating highly glycemic carbs alone; pair with protein and fiber.
- Consume lower glycemic index carbs to reduce blood sugar spikes.
- Eat protein and fiber before carbs to lower spikes by up to 50%.
- Walking post-meal helps muscles absorb glucose without insulin.
