Refined carbohydrates, often found in processed foods and sugary drinks, are quickly broken down into glucose, causing rapid spikes in blood sugar levels. Sugars and sweeteners, especially those with a high glycemic index, contribute to these spikes. Several U.S.-based studies have highlighted the detrimental effects of excessive refined carbohydrate and sugar intake, including:

• Increased risk of type 2 diabetes: The Nurses’ Health Study found that women who consumed more sugary drinks had a significantly higher risk of developing type 2 diabetes.
• Weight gain and obesityObesity is a medical condition where someone has excessive body fat that can negatively affect their health. It’s not just about weight, but also about the amount of fat that accumulates in the body, especially around the belly.

Less frequently, it can lead to more serious side effects like lactic acidosis, a rare but potentially life-threatening condition.
• Synonyms: Metformin is also known by several brand names, including Glucophage, Glumetza, and Fortamet.
• Interesting Facts: Metformin is one of the oldest and most widely used diabetes medications globally, with a long track record of safety and effectiveness. It’s also one of the few medications on the World Health Organization’s List of Essential Medicines.
• Controversies: While metformin is generally considered safe and effective, some controversies exist regarding its potential long-term effects, including its impact on vitamin B12 levels and its possible role in cancer prevention or treatment. Ongoing research continues to explore these aspects.

Conclusion

In essence, metformin is a key regulator of glucose metabolism in the body. It helps maintain healthy blood sugar levels, primarily in individuals with type 2 diabetes, by influencing glucose production, absorption, and utilization. Its multifaceted actions extend beyond diabetes management, with potential benefits in areas like PCOS, weight management, and even cancer prevention. Understanding the role of metformin in the context of a ketogenic lifestyle, where fat is the primary fuel source, highlights its potential to indirectly support ketosis by improving insulin sensitivity and lowering blood sugar. While metformin is generally safe and well-tolerated, it’s essential to be aware of its potential side effects and interactions, especially with vitamin B12. As research continues to uncover new insights into metformin’s mechanisms and potential applications, it remains a cornerstone of diabetes management and a promising avenue for future therapeutic interventions.
