Study Sheds Light on a Better Way to Control Diabetes: Intermittent Fasting

In a ground breaking study conducted by researchers at the University of Illinois Chicago, time-restricted eating, more commonly known as intermittent fasting, has emerged as a safe and effective strategy for individuals with Type 2 diabetes. The study, published in JAMA Network Open, offers hope and practical solutions for those struggling with diabetes and its associated health challenges.

The Power of Time-Restricted Eating

The study involved 75 participants who were divided into three groups: one group followed time-restricted eating rules, another group was instructed to reduce their calorie intake by 25%, and a control group. Over a six-month period, the researchers closely monitored various health indicators, including weight, waist circumference, and blood sugar levels.

What makes this study particularly exciting is the discovery that participants who adhered to a strict eight-hour eating window, from noon to 8 p.m., actually lost more weight compared to those in the calorie-reduction group. Even more encouraging, both groups experienced similar reductions in long-term blood sugar levels, as measured by hemoglobin A1C, which reflects blood sugar levels over the past three months.

Embracing a Simpler Approach

Senior author Krista Varady, a professor of kinesiology and nutrition, highlighted that participants following the time-restricted eating regimen found it more manageable than their calorie-restricting counterparts. This could be attributed to the fact that conventional dietary advice for diabetes often includes calorie reduction, a challenging approach for many patients. In contrast, time-restricted eating doesn’t require a strict focus on calorie counting. This approach centers on when you eat rather than how much you eat.

Varady commented,

Our study shows that time-restricted eating might be an effective alternative to traditional dieting for people who can’t do the traditional diet or are burned out on it. For many people trying to lose weight, counting time is easier than counting calories.

Safety First

One crucial aspect of this study is the safety profile of time-restricted eating. Notably, there were no reports of serious adverse events during the six-month research period. Incidences of hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) were similar in both the time-restricted eating and calorie-reduction groups when compared to the control group. This is reassuring news for individuals with Type 2 diabetes, as managing blood sugar levels is paramount.

A Growing Health Concern

The significance of this study extends beyond its impressive results. As the researchers point out, diabetes is an increasingly prevalent condition, with 1 in 10 U.S. residents currently affected. If current trends continue, this number is projected to rise to a staggering 1 in 3 by 2050. Therefore, finding effective strategies for weight management and blood sugar control is critical.


It’s worth noting that just over half of the participants in the study were Black, and another 40% were Hispanic. These demographic groups are particularly susceptible to diabetes, making it essential to document the effectiveness of time-restricted eating for them. The study’s results provide hope and potential solutions for individuals from these communities who are disproportionately affected by Type 2 diabetes.

What Lies Ahead

While this study provides promising insights into the safety and effectiveness of time-restricted eating for individuals with Type 2 diabetes, the authors emphasize that further research is needed. The study serves as a proof of concept, demonstrating the potential of this dietary approach. However, it’s crucial for individuals with diabetes to consult their healthcare providers before embarking on any significant dietary changes.

This ground breaking research represents a significant step forward in the fight against Type 2 diabetes. It offers hope for individuals who have struggled with traditional dieting and calorie counting, and it paves the way for further studies to explore the full potential of time-restricted eating. As we look toward the future, we can anticipate more innovative and accessible strategies to manage diabetes and improve the lives of those affected by this widespread condition.
