A new study suggests that limiting daily food intake to an 8-hour window may lead to more weight loss than a 12-hour window, though results for other health markers were limited.
Key facts
- •The study analyzed 124 adults who had at least one component of metabolic syndrome at the start of the trials.
- •Participants in the 8-hour window group lost 3.7 pounds more than those in the 12-hour group.
- •There was no significant difference in weight loss between the 8-hour and 10-hour eating windows.
- •The 10-hour eating window was associated with a significant reduction in systolic blood pressure compared to the 12-hour window.
- •Experts suggest focusing on a balanced diet and avoiding late-night eating rather than strictly adhering to a specific number of hours.
A study published September 12 in the journal Nutrition & Diabetes indicates that an 8-hour time-restricted eating window may result in greater weight loss compared to a 12-hour window or no restriction. Researchers analyzed data from 124 adults with metabolic syndrome across five trials lasting three to six months. Participants in the study limited their daily eating periods without specific restrictions on calorie intake or food quality.
By the numbers
Weight Loss and Metabolic Findings
Participants assigned to an 8-hour eating window lost approximately 3.7 pounds more than those on a 12-hour window and about 5 pounds more than the control group. However, researchers found no statistically significant difference in weight loss between 8-hour and 10-hour windows. While the 10-hour window showed a significant reduction in systolic blood pressure compared to the 12-hour window, the study found no significant impact from the 8-hour window on blood pressure, glucose, or cholesterol levels.
Expert Perspective on Implementation
Dalia Perelman, a research dietitian at Stanford Medicine, noted that the benefits may stem from shortening one's habitual eating period rather than adhering to a specific eight-hour limit. She emphasized that time-restricted eating should be viewed as one component of a broader lifestyle approach rather than a standalone treatment. Perelman advised that individuals with diabetes or those at risk for muscle loss should consult healthcare professionals before starting such regimens, as medication adjustments or specific nutritional needs may be required.
