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?

Should You Eat More Frequently To Lose Weight?

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.)

How To Lose 10 Pounds This Spring With A Healthy Meal Plan

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.”

Why People With Diabetes Should Avoid Meal Skipping

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!

Lately, however, the trend of intermittent fasting — such as eating an early dinner and then not having a meal until after noon the next day (in other words, skipping breakfast!) — has taken off and confused many of us about what meal timing is best. Similarly, trendy carb cycling can also marry well with the concept of skipping breakfast.

Is It Good For Teens To Skip Breakfast And Lunch Then Workout In The Evening, So They Can Get Rid Of Their Belly Fat?

The big-breakfast approach works for some, especially those who like to exercise in the morning and need to refuel afterward. There’s plenty of research suggesting that when breakfast is full of protein and fiber, it can be beneficial for appetite management.

So is breakfast important, or should you forgo it in order to lose weight? Let’s look below at the pros and cons of delaying your first meal of the day.

A large clinical review looked at 13 studies to investigate the impact of eating breakfast on weight gain and consistently found that those who regularly eat breakfast had better protection against becoming overweight or obese compared to those who skipped it.

How Breakfast Helps With Weight Loss

A study done by researchers at Tel Aviv University showed that dieters lost more weight when they ate the majority of their calories in the morning (roughly 700 calories) compared to those eating more throughout the day and at nighttime.

While all participants followed a low 1, 400-calorie diet, meal timing made a significant difference in terms in weight loss. The group eating 700 calories (or half of daily calories) in the morning lost eight more pounds over a 12-week period than the group eating more calories during dinnertime.

The participants who ate half of their daily calories at breakfast lost more weight and more inches from their waists, showed greater improvements in glucose control and insulin sensitivity, and reported being more satisfied. The researchers found that the big-breakfast eaters had lower levels of ghrelin, our main hunger hormone.

Intermittent Fasting For Weight Loss: Should You Miss Your Breakfast Or Dinner?

Found that missing breakfast causes metabolic and hormonal impacts that can make it hard to choose healthier foods in the right portion later in the day. The study found that those who skipped breakfast had differences in responses to foods consumed later in the morning, higher appetites and an increase in energy intake compared to people who ate breakfast.

Many other studies show the same and report that for most people who have lost weight and been able to keep it off, eating breakfast is part of what allows them to be successful long term.

Fill up on the right foods upon waking up, especially kinds that are high in protein and high in healthy fats, and you might find you’re more prepared to work, move and make better decisions all day long.

Skipping Breakfast Linked To Weight Loss In New Study

Overall, when we look at studies conducted over the past decade, we see very mixed results in terms of what constitutes ideal meal timing. Some studies show that adults can maintain their weight more easily when they “front load” their day with bigger meals and more calories, but other studies show the opposite can work, too.

Found that contrary to popular belief, there was no metabolic increase after eating breakfast, no suppression of appetite or calorie intake later in the day, and no difference in terms of weight gain or loss between people who ate breakfast and those who didn’t.

While overall body mass, blood sugar levels and adiposity (fat levels) didn’t differ between breakfast-eaters and breakfast-skippers, those who eat breakfast did seem to naturally move around more throughout the morning. This increase in physical activity didn’t have any effects on weight, cardiovascular health, insulin responsiveness or other markers, however.
