Type 2 diabetes is one of the most formidable health challenges of our time. Nearly 600 million adults worldwide live with this chronic disease, in which the body either fails to produce enough insulin (the hormone that helps glucose enter our cells) or becomes resistant to it, meaning the cells don’t respond properly. As a result, too much glucose remains in the bloodstream and too little reaches the cells for fuel.
According to the 11th edition of the International Diabetes Federation (IDF) Diabetes Atlas, in 2025, an estimated 589 million adults aged 20–79 worldwide were living with diabetes, equivalent to roughly one in every nine adults. That number is projected to climb to 853 million by 2050.
To draw attention to the issue and raise awareness, IDF continues to lead World Diabetes Day on November 14th every year. This year is no exception. And the goal remains unchanged — to help people make better lifestyle choices that could prevent the disease.
For years, type 2 diabetes was often viewed as a permanent condition. But emerging research and clinical experience are now beginning to offer a silver lining. Evidence is showing that, with the right combination of diet, lifestyle, weight management, and food choices, people can not only manage but, in some cases, even reverse the condition, primarily by improving insulin sensitivity. For example, researchers at Yale School of Medicine state that: “If you reverse insulin resistance, you reverse type 2 diabetes.”
So how do you improve insulin sensitivity and keep your blood sugar and insulin levels from swinging wildly? The key isn’t about deprivation — it’s about smart choices and timing. It’s about what you eat and when you eat it.
