Your Guide to the Blood Sugar Diet: Best Foods to Eat and Avoid

The Blood Sugar Diet is a dietary approach focused on stabilizing blood sugar levels to promote weight loss and improve overall health. Developed by Dr. Michael Mosley, this diet isn't just another fad; it's rooted in scientific understanding of how our bodies process sugar and the impact that has on our well-being. This guide will provide you with the key information on the best foods to eat and those foods to avoid when following the Blood Sugar Diet, along with actionable tips and insights to make the most of this approach.

Understanding the Blood Sugar Diet

Before diving into the specifics of what to eat and what to avoid, let's first understand the core principles behind the Blood Sugar Diet. The diet revolves around the idea that unstable blood sugar levels can lead to insulin resistance, weight gain, and an increased risk of type 2 diabetes.

The diet typically involves a reduced-calorie intake (around 800 calories per day) for a short period, coupled with a focus on low-carbohydrate foods and healthy fats. While the initial phase is intensive, the goal is to transition into a more sustainable long-term eating pattern.
