Meal Repetition May Aid Weight Loss

Building healthy habits often hinges on consistency, and it seems our daily meal choices might fit this idea too.

Researchers from Drexel University in the US have discovered that sticking to the same meals and snacks regularly could lead to more effective weight loss over several months.

While having a varied diet is certainly important for overall health, these new findings indicate that repeating certain meals can actually be beneficial for those aiming to shed pounds.

It appears that maintaining a consistent set of meals can perhaps be more effective for weight loss than frequently changing what you eat.

Charlotte Hagerman, a health psychologist at Drexel University and the study’s lead author, notes, “Maintaining a healthy diet in today’s food environment requires constant effort and self-control.” She adds that establishing routines around meals might lighten that load, making healthy decisions feel more automatic.

In this study, Hagerman and her colleagues examined food logs from 112 overweight or obese adults participating in a structured weight-loss program.

During the program’s initial 12 weeks, participants who had consistent meals and caloric intake generally lost more weight compared to those who varied their food choices, often fluctuating in calorie consumption.

Specifically, those following a more routine diet lost about 5.9 percent of their body weight on average, while those who mixed it up lost around 4.3 percent. A small difference, sure, but it could be significant over time if the weight loss is sustained.

The research team found that for every hundred calories difference in daily intake, weight loss decreased by 0.6 percent over the 12-week period.

This study, while limited and not enough to dismiss the benefits of a diverse diet entirely, suggests a new perspective. It’s important, as always, to consult a doctor before making major dietary changes.

Interestingly, this research is among the first to use real-time food tracking to see how sticking to a routine can impact weight loss over several months.

The results imply that our constant exposure to a wide range of food might actually hinder some weight-loss efforts.

Hagerman suggests, “In a healthier food environment, we might encourage more variety in diets. But our current food landscape presents challenges. Instead, people might do better with a more repetitive diet to foster healthier choices, even if it means sacrificing some nutritional variety.”

It’s worth noting that the study did not assess the overall nutritional quality of participants’ diets, which might mean they were losing weight through less healthy food options.

Participants were enrolled in a behavioral weight-loss program where they collaborated with coaches to set daily caloric goals and weekly weight-loss targets.

They had two methods available: maintaining a consistent daily calorie intake or averaging their caloric intake over the week, saving some calories for special occasions.

Notably, participants who tracked their food consistently lost more weight if they had a routine diet.

While researchers can’t firmly state that a routine diet directly causes weight loss, the correlation is intriguing.

They suggest that even a healthy, diverse diet may lead to more decision-making points, complicating calorie calculations, compared to having a handful of go-to meals with predetermined calorie counts.

It sounds like the groundwork is laid for a potential clinical trial.
