- A recent study has found that eating the same meals each day could lead to greater weight loss.
- The findings suggest that consistent caloric intake helps with weight loss.
- The study doesn’t establish a cause-and-effect relationship, but it does show a correlation between having “go-to” foods, consistent calorie intake, and weight loss.
Having the same “go-to” meals and eating a consistent amount of calories each day may help people to lose more weight, according to a new study.
Participants who followed a routine eating pattern lost more weight during a 12-week behavioral weight loss program than those who followed a more varied diet.
“There’s compelling evidence to consider here that consistency and predictability in eating may help some individuals eat better and lose weight — but it’s important to note the limitations, including self-reported data, a highly structured program environment, and an observational study design,” said Kristin Kirkpatrick, registered dietitian at The Cleveland Clinic Department of Wellness & Preventive Medicine and president of KAK Consulting. Kirkpatrick was not involved in the study.
The study analyzed real-time, detailed food logs from 112 adults with overweight or obesity who were enrolled in a structured behavioral weight loss program.
The participants tracked everything they ate each day using a mobile app. They also had daily weigh-ins using a wireless scale. To ensure the data reflected consistent habits, the researchers focused on the first 12 weeks of the program. This is a period when people are generally the most engaged and accurate in tracking their food habits.
The researchers measured how routine each person’s diet was in two ways:
- caloric stability, or how daily calorie intake fluctuated from day to day and between weekdays and weekends
- dietary repetition, or how often individuals tracked the same meals and snacks over time
The research team found that individuals who repeated the same foods rather than eating a wide variety of foods lost an average of 5.9% of their body weight. This is compared with a 4.3% loss among those with a more varied diet.
“Consistency works best when the foundation is strong. If meals are nutrient-dense, they can reinforce high quality nutrition. But if they’re missing key nutrients, you may consistently fall short,” said Kirkpatrick.
“In the real world, with travel, stress, and changing schedules, that level of consistency isn’t always realistic without structure or support,” she said.
The study also found that greater consistency in calorie intake was associated with greater weight loss results. For every 100-calorie increase in daily fluctuation, individual weight loss decreased by around 0.6% during the study period.
The findings suggest that simplifying food choices may help individuals to build sustainable, healthy habits, even in challenging food environments. This might include rotating “go-to” meals and maintaining a steady calorie intake.
“Most people eat the same 20 to 30 foods repeatedly each week,” said David Cutler, MD, board certified family medicine physician at Providence Saint John’s Health Center in Santa Monica, CA. Cutler was not involved in the study.
“It is not surprising that successful weight controllers limit their food choices as well. And certainly, limiting those foods to healthier choices and recognizing their calorie contents will assist in losing weight,” Cutler told Healthline.
Despite the promising results, the study doesn’t show a cause-and-effect relationship, but rather a correlation. Factors such as motivation or self-discipline may also play a role in results.
Still, the findings suggest that when it comes to weight loss, consistency may be more important than variety.
According to the National Institute of Diabetes and Digestive and Kidney Disease (NIDDK),
Not every process will work the same for everyone. Ask your doctor about the best way to lose weight based on your circumstances and health status.
“The best place to start is with a truly personalized plan — ideally developed with a registered dietitian — that considers your preferences, labs, medications, genetics, and lifestyle,” said Kirkpatrick.
“There’s no one-size-fits-all approach. The most effective plan is the one that works for you and your life,” she continued.
