A new study suggests that time-restricted eating—where individuals consume all their food within a specific window, such as noon to 8 p.m.—may help improve blood sugar control in adults with Type 1 diabetes and obesity. The research, led by Krista Varady, a professor of kinesiology and nutrition at the University of Illinois Chicago, involved 32 participants from the Chicago area. They were randomly assigned to one of three groups over a six-month period. One group followed a time-restricted eating schedule, another reduced their calorie intake by 25%, and the third group made no changes to their usual eating habits. The results showed that the time-restricted eating group had better blood sugar outcomes compared to the calorie-reduction group. On average, their HbA1c levels—measured through a blood test that reflects average blood sugar levels over the past two to three months—decreased by about 0.5%. This improvement suggests that timing of meals may play a significant role in managing blood sugar, in addition to the total number of calories consumed. Notably, the study found no increased risk of dangerously high or low blood sugar levels, or diabetic ketoacidosis—a serious complication in Type 1 diabetes—among participants following the time-restricted eating plan. Varady emphasized that the study is an early step in understanding how time-restricted eating might benefit people with Type 1 diabetes and obesity. She cautioned that individuals should not change their eating habits without consulting a healthcare provider. Varady hopes to conduct larger studies across multiple research sites to confirm whether these findings apply more broadly. This research could eventually lead to new dietary strategies for managing diabetes, but more evidence is needed before any specific recommendations can be made.
