Yet another study has dispelled the popular “you have to eat breakfast” myth, and I’m thrilled. The breakfast cereal aisle is the most nutritionally horrifying area of the supermarket, crawling with sugary carbs in all shapes and flavors, all disguised as food.

It’s true — eating breakfast is not associated with eating less nor with weight loss, which begs the question: can skipping breakfast help with weight loss?

Scheduled Eating Why It's Beneficial And How To Start

A plethora of intermittent fasting studies suggest that extending the overnight fast is indeed associated with weight loss, but also more importantly, with improved metabolism. Overnight fasting of at least 16 hours (which really isn’t that extended) allows blood sugar and insulin levels to decrease, so that fat stores can be used for energy. This makes physiologic and logical sense: Our bodies can’t burn fat if we keep filling it with fuel. The idea that having a meal first thing in the morning revs up the metabolism isn’t based in reality.

So where did the “breakfast is good for you” myth come from? Wasn’t it based on research? Yes, but it was not the right kind of research. Observational studies produce interesting observations, and that is all. At the population level, people who regularly consume breakfast also tend to be a ier weight. That doesn’t mean that breakfast has anything to do with it. It may be that people who regularly consume breakfast also tend to have daytime schedules (no night shifts), or higher socioeconomic status (can afford breakfast), or generally more consistent habits than those who don’t. These are all more important variables associated with ier weight, and observational studies don’t reveal any of that.

So how do you properly study the effect of eating breakfast (or not) on weight? You’d want to conduct a randomized controlled trial (RCT) evenly dividing participants into breakfast vs. no-breakfast groups, and then measure specific outcomes, like daily calorie intake and weight. RCTs are experiments where you can control for confounding variables, and thus feel more confident about drawing conclusions. (Having said that, RCTs can have other issues, and we’ll go into that.)

This Is The Ideal Time Gap Between Waking Up And Eating Breakfast

Researchers from Melbourne, Australia looked at a number of RCTs on breakfast and weight and/or total daily energy intake, and pooled the results. They found 13 studies in all that met their criteria: they had to define breakfast content and timing, and had to have been conducted in high-income countries (to be more comparable).

The authors do point out that the RCTs had flaws. Participants knew what experimental group they were in. The studies used various groups (college students, hospital staff, general public); featured different foods (crisped rice, wheat flakes, oatmeal); and had widely varying follow-up times. The RCT comparing a high-protein, high-fiber breakfast with nothing has yet to be conducted.

Still, in the end, the authors conclude: “While breakfast has been advocated as the most important meal of the day in the media since 1917, there is a paucity of evidence to support breakfast consumption as a strategy to achieve weight loss, including in adults with overweight or obesity.”

Having said all this, if you love love love your breakfast, and you’re y, then enjoy! If you’re struggling with a metabolic medical problem, consider a breakfast of water, tea, or coffee and then have a y lunch. Or, at the very least, try not to eat close to bedtime. Whatever your preferred schedule, try to stretch out the time between meals, and give your body a chance to burn fat. Your metabolism will thank you!

Skipping breakfast and other meals is one behavior studied as a factor influencing weight outcomes and dietary quality. Based on evidence that skipping breakfast reduces total daily caloric intake, some weight-loss recommendations include skipping breakfast (i.e., intermediate fasting) as one strategy to use. USDA's Economic Research Service () research suggests that while skipping meals can cut calories, this may also reduce diet quality.

USDA and other Federal agencies engage in nutrition education efforts to improve U.S. diets. research investigated how skipping meals—breakfast, lunch, and dinner—affects calorie intake and diet quality among U.S. adults to see if this action conflicts with these education efforts and nutrition advice. Along with dietary effects, if the decision to skip a meal is widespread and sustained, there could be economic implications for agricultural produc, food processors, and oth in the food supply chain.

The research used 2 days of food intake data for U.S. adults from the National Health and Nutrition Examination Survey (NHANES) for 2007-16. These data capture detailed information about the types and amounts of food consumed in 2 non-consecutive days, as well as when each food was eaten and if it was part of a meal or a snack. The research used the Healthy Eating Index (HEI), which is a measure of how well a pon’s diet conforms with recommendations in the

, to gauge diet quality on each day. The HEI is made up of 12 dietary components encompassing food groups (fruit, dairy, whole grains, etc.) and dietary elements (fatty acids, empty calories, sodium, etc.). The HEI sums to a maximum total score of 100, with a higher score reflecting better diet quality. The score includes nine adequacy components—eight food groups and fatty acids—where higher consumption raises scores. The other three are moderation components—refined grains, sodium, and empty calories—with higher scores reflecting lower consumption and therefore, better diet quality.

It's Okay To Eat When You're Not Hungry

Using the 2 days of intake for each survey respondent, the research used a statistical model that allowed them to control for individual characteristics that do not change between the 2 days (e.g., demographic variables and unobserved food and eating preferences). What remains are variables that may differ between the 2 days (e.g., the types and amounts of foods consumed and number of meals eaten), allowing the research to estimate how changes in day-to-day eating patterns (skipping a meal) affect the calories consumed and diet quality.

The results show that skipping a meal reduced daily caloric intake between 252 calories (breakfast) and 350 calories (dinner). However, skipping breakfast or lunch decreased diet quality by about 2.2 points (about 4.3 percent), while skipping dinner lowered diet quality by 1.4 points (2.6 percent). The dietary components affected by skipping each meal differed:
