The Truth About Type 2 Diabetes: What the Science Says

In this episode of Mastering Blood Sugar, we break down the real causes of type 2 diabetes and what the evidence says about reversing it. With so much misinformation online, it’s easy to get caught up in debates over carbs, fats, and sugar—but what does the research actually show?

What’s Really Causing Type 2 Diabetes?

The primary driver of type 2 diabetes isn’t just one food or macronutrient. The biggest factor is excess fat accumulation, particularly in the liver and pancreas. Research shows that losing this fat, regardless of diet, can significantly improve insulin resistance and even put diabetes into remission.

How to Reverse Type 2 Diabetes

The strongest predictor of diabetes remission is weight loss—specifically, fat loss in key areas. Studies like the DIRECT trial show that even moderate weight loss can restore blood sugar control. However, different approaches work for different people. Low-carb, Mediterranean, and fasting-based diets have all shown success. The key is sustainability—choosing a method that works long-term.

Should You Worry About Blood Sugar Spikes?

With the rise of continuous glucose monitors (CGMs), many worry about brief post-meal blood sugar spikes. But the science is clear: temporary increases are normal. The real concern is when blood sugar remains elevated for extended periods. Instead of focusing on small fluctuations, it’s more important to look at overall patterns and long-term metabolic health.

The Bottom Line

Type 2 diabetes is not a lifelong, irreversible disease. The research shows that reducing excess body fat—especially visceral fat—can restore normal insulin function. Multiple dietary strategies can work, but sustainability is key. Rather than getting caught up in diet trends or fear-based nutrition advice, focus on what actually leads to long-term success.
