Weight loss is pretty tricky. Some folks can lose weight without much effort, while others have to think carefully about their strategies to actually see results.
Recent research in the International Journal of Behavioral Nutrition and Physical Activity presents an idea that might be worth a try: it’s about focusing on when you eat, rather than just what you eat. It’s somewhat similar to concepts like intermittent fasting, but this approach is more flexible, concentrating on timing habits instead of adhering strictly to a schedule. The findings suggest that adjusting your eating times could result in a lower BMI over time.
If you’re feeling stuck in your weight loss journey, this might be an aspect to explore—and it seems like a more approachable way to make adjustments.
Experts involved in the research include Camille Lassale, PhD from the Barcelona Institute for Global Health; Lisa Moskovitz, RD, founder of NY Nutrition Group; and Mir Ali, MD, medical director at MemorialCare Surgical Weight Loss Center.
What did the study find?
The researchers examined data from over 7,000 adults aged 40 to 65 who participated in a long-term study in Germany. Initially, participants provided their height, weight, meal timing, lifestyle habits, and socioeconomic details.
Five years later, about 3,000 participants returned for follow-ups. They took updated measurements to see how things had changed.
The analysis revealed that two habits were linked to a lower BMI: having a longer overnight fasting period and eating breakfast early. In essence, these individuals skipped late-night snacks and had breakfast sooner.
The exact timing varied, but interestingly, women with the lowest BMI usually had breakfast around 7:30 a.m., and there was a 10.5-hour gap between their last meal and breakfast. So, if you want to do the math, if you’re having breakfast at 7:30, you’d need to stop eating by 9 p.m.
Delaying breakfast seemed to correlate with a higher BMI, according to the findings.
Why might this combination help with weight loss?
It’s key to highlight that the study indicates a correlation, not a cause-and-effect relationship. But some thoughts suggest why this might be beneficial.
Camille Lassale, PhD, explains that nutrient handling—especially regarding insulin, metabolism, and hormones—shifts throughout the day. It’s generally more effective during daylight hours and less so at night. So, eating breakfast early and having dinner earlier could aid weight management.
Lisa Moskovitz, RD, adds that hormones influencing appetite and blood sugar levels also play roles in weight and body fat. Late-night eating often leads to snacking, which can result in unhealthy choices and, ultimately, weight gain, as pointed out by Mir Ali, MD.
How is this different from intermittent fasting?
The concepts of “timing” and “fasting” often bring intermittent fasting to mind, but experts clarify that these tips differ somewhat. Intermittent fasting usually means longer periods of fasting, like the 16:8 method where you fast for 16 hours and eat for 8. In contrast, this method feels more adjustable and might even be easier to maintain.
Lassale further notes that intermittent fasting is typically a deliberate choice, whereas many study participants naturally followed this eating pattern without applying strict rules.
What’s the takeaway?
The findings stress the significance of consistent meal times and giving your body time for digestion before hitting the hay. “Skipping breakfast isn’t the solution for extended overnight fasting,” points out Lassale. She recommends a healthy morning meal and an early, lighter dinner.
Moskovitz concurs, saying you don’t need drastic changes to impact your body fat levels. Essentially, this strategy involves consuming more calories earlier in the day, which might be unfamiliar if you typically have larger dinners and snacks at night.
Although it can be tough for those who prefer evening meals, this shift may yield noticeable benefits. If you usually consume most of your calories late in the day, making this change could bring positive results.
And beyond just a lower BMI, Moskovitz suggests that this approach might improve sleep, energy levels, digestion, and cravings by supporting blood sugar and insulin balance.
