Is breakfast the most important meal of a day?
Today, many people like to skip breakfast because they are busy in the morning or to help manage their food intake across the day.
But what can half a million days of MyFitnessPal data tell us about whether eating breakfast is optimal to manage our appetite in order to stay healthy and lean?
To understand the effect of breakfast on our appetite we plotted the proportion of calories consumed at breakfast versus the degree to which people were able to achieve their calorie goal when logging in MyFitnessPal. A score of greater than 100% means that a person was not able to achieve their target calorie intake. A score of less than 100% indicates that a person’s reported consumption was under their goal.
Granted, there are limitations with self-reported data versus a metabolic ward study, but many of the concerns are common across the board and cancel themselves out. While there is plenty of scatter, there is a definite trend towards eating less across the day in the people that consumed more of their daily calories at breakfast.
To help make sense of all the scatter, the chart below shows the average for the different “bins” of data based on the proportion of a person’s daily calories consumed at breakfast.
Most people instinctively prefer to eat a larger dinner with a minimal breakfast. But keep in mind that our instincts have developed to help us avoid starvation and store fat in preparation for winter, not to avoid diabetes or look good naked.
It’s often more convenient to eat at night when we are with our family and friends and have unlimited access to our fridge and cupboard. It’s easy to sit down in front of Netflix with a bag of chips and chocolate and eat mindlessly. Afterwards, you go to sleep which maximises your body’s opportunity to store the food you just ate.
This data seems to align with emerging research indicating that early time restricted-feeding (eTRF) approach with a hearty meal eaten earlier in the day helps to improve satiety and reduce appetite.
The study from Satchin Panda’s lab found that, on average, people eat for 14.75 hours per day. On average, people consume their maintenance calories by 6:36 pm, but many continue to eat as long as they are still conscious.
In the second phase of the study participants were encouraged people to follow a more compressed eating window with their the bulk of their food consumed earlier in the day. Although it took some time to adjust, they unanimously loved the change!
