Meal Frequency and Fat Loss
It’s commonly believed that consuming small, frequent meals optimizes fat loss. According to theory, go without eating for more than a few hours and your body shifts into “starvation mode.” Part of the starvation response is to slow down metabolism in an effort to conserve energy. Pretty hard to get lean when your metabolic rate isn’t cooperating. Conceivably, providing your body with a constant stream of nutrients prevents the starvation response by “stoking the metabolic furnace,” thereby enhancing the ability to burn stubborn body fat.
Or so the theory goes…
Despite a seemingly logical basis, however, the evidence generally doesn’t support metabolic benefits of increased meal frequency. A study in dogs did show that consuming four small meals doubled the thermogenic response compared to eating an energy-equated amount of food as a large single meal.9 A follow-up study by the same group of researchers found similarly beneficial thermogenic effects in humans from a greater feeding frequency.10 On the other hand, a number of other tightly controlled human and animal trials have failed to show increases in metabolism as a result of spreading nutrient intake over multiple meals.5,7,13,18,19
While acute studies on metabolism provide interesting mechanistic insight into the body’s immediate response to different feeding frequencies, the only thing that really counts is whether a strategy of eating more frequently enhances fat loss. And the only way to determine actual fat loss is through randomized controlled trials (RCTs) that study this outcome directly.
My lab carried out a meta-analysis to gain greater clarity on the topic. We searched back to the early 1960s to find any and all RCTs that compared feeding frequencies of less than or equal to three meals a day with greater than three meals a day. Studies had to last a minimum of two weeks, involve healthy adult men and/or women, and equate the number of calories consumed between conditions. A total of 15 studies were determined to meet inclusion criteria. The results of these studies were then pooled for analysis to determine what, if any, effects on body composition can be attributed to how often you eat.
Feeding frequency had no effect on overall bodyweight. This seems in line with the findings of the acute studies mentioned earlier. Interestingly, however, our initial analysis did reveal a positive correlation between fat loss and the number of daily meals consumed. Here’s the rub: A sensitivity analysis found that these results were almost exclusively attributed to a single study6— the effects all but disappeared when this study was selectively removed from analysis. A positive association also was initially found between meal frequency and reductions in body fat percentage, but again these results were unduly biased by one study1 whose deletion rendered the results inconsequential.
So what can we glean from our research? Contrary to popular belief, it doesn’t appear that eating small, frequent meals provides any meaningful benefits to fat loss. This was particularly apparent from the metabolic ward trials included in our analysis. As opposed to “free living” studies that allow subjects to self-report dietary habits (and thus have been shown to be quite unreliable), research carried out in a metabolic ward meticulously controls these variables; every morsel of food and every step of activity is carefully monitored by the investigators. Without exception, these studies showed no benefit to fat loss from higher meal frequencies.
Now a caveat to our meta-analysis is that we only included studies that matched caloric intake between feeding frequencies. This was necessary to rule out the potential for confounding from unequal energy consumption. However, some claim that the true benefit of an increased meal frequency is a better control over hunger, conceivably by regulating blood sugar and hormonal levels. If true, this in itself would promote a beneficial effect on fat loss given that weight management is basically a function of energy balance: take in more calories than you expend and you'll gain weight; create a caloric deficit and you'll lose weight.4 Thing is, research is conflicting on the topic. Although some studies have found that spacing out meals over the course of a day reduces hunger,14-17 others show no differences in satiety regardless of feeding frequency.3,12 Several studies have even found greater feelings of fullness from consuming three as opposed to six daily meals.11,13 Considering the body of literature as a whole, evidence remains weak that eating frequent meals helps to control hunger; any beneficial effects are likely specific to the individual.
The take-home message here is that eating small, frequent meals appears to have little if any effect on reducing body fat. From this standpoint, meal frequency should therefore come down to personal preference: choose whatever frequency fits your lifestyle. Focus on what’s important to achieving fat loss: creating a negative energy balance and consuming adequate dietary protein.
Aside from fat loss, there is a compelling reason why feeding frequency may have important implications on body composition. Namely, the anabolic effects of a meal have been estimated to last approximately five to six hours based on the rate of postprandial amino acid metabolism.8 Given that you’ll generally spend at least 16 hours of the day awake, you thus need at least three protein feedings to maximize anabolism. Indeed, recent research indicates that spreading protein intake out over four daily servings increases muscle protein synthesis to a greater extent than consuming the same amount of protein in two larger servings.2 So eating a minimum of three daily meals spaced out no more than every five to six hours is a prudent strategy to promote lean muscle.

Choosing a Fitness Professional: Finding the Right One for You
In an industry that is constantly evolving, the world of fitness is never boring. As a fitness professional, I get a lot of questions about what I do and why I do it. Each question, although relatively complex, has a simple answer.
I chose my profession because I love to motivate, converse, educate, and be enthusiastic around other people. My passion made college classes and clinical research thrilling. I also wholeheartedly believe that a healthy lifestyle extends positively to all aspects of an individual’s life, as well as their family, friends, and coworkers. The human body is miraculous and deserves to be treated so.
The incidence and severity of disease can be decreased through regular physical activity (insert flashing neon arrows). Even so, large populations of individuals still do not have the knowledge to maintain an active lifestyle for themselves or their families as preventative action. It is my career goal to educate those individuals who might not know where to begin or how to progress, or have diminished hope, through behavioral-change goals. However, in an industry that also has many non-credible sources and educators, it is important to be able to separate the two.
Below are some of the regularly asked questions within our field and their answers to help you in choosing a fitness professional who best fits into your plan.
What Is a Fitness Professional?
The best definition of a fitness professional comes from the American College of Sports Medicine:
“A Health Fitness Professional has a minimum of a bachelor’s degree in Exercise Science. The individual performs pre-participation health screenings, conducts physical fitness assessments, interprets results, develops exercise prescriptions, and applies behavioral and motivational strategies to apparently healthy individuals and individuals with medically controlled diseases and health conditions to support clients in adopting and maintaining healthy lifestyle behaviors. Academic preparation also can include fitness management, administration, and supervision.” (2015)
How Do You Become a Fitness Professional?
To become a fitness professional an individual must obtain a four-year degree or a graduate degree in Exercise Science, Kinesiology, Health Studies or in a health and fitness–related field. After graduating, an exam is taken through a certifying body, such as the American College of Sports Medicine (ACSM) or the National Academy for Sports Medicine (NASM). Some of the most common exams include the Certified Exercise Physiologist (formerly Health Fitness Specialist) and the Certified Personal Trainer. If an individual is in a cardiac rehab environment and obtains 400/500 hours of clinical exercise programming, the professional can then apply to take a clinical-level exam.
How Do Fitness Professionals Stay Up-to-Date?
ACSM is the largest sports medicine and exercise science organization in the world, and they continue to set the standards in the fitness industry. ACSM requires a minimum number of CECs (continuing education credits) and CEUs (continuing education units) in a three-year period to maintain certification.
NASM, a leader in providing technology-based education and certification solutions, also offers CEUs alongside specialization exams.
Alongside CECs, CEUs, and specialization exams, individuals can subscribe to additional research publications and continue to take certifying exams. Attending conferences, taking graduate classes in the field, and meeting other individuals in the industry is also a great way to network and learn from peers.
How Do I Choose a Fitness Professional That Is Right for Me?
Today, many individuals market themselves as trainers or nutritionists. When choosing an individual to work with, ask about their education and background, how many clients they have worked with, and their specializations. Working directly with an individual is similar to hiring for a job; don’t be afraid to ask for their resume or references! An individual who is qualified should happily comply.
It is also important to remember that a fitness professional is not a Registered Dietitian (RD). According to ethical guidelines, a fitness professional can discuss and provide insight into healthy alternatives but can’t develop meal plans or suggest drastic diet changes. For in-depth nutrition advice, a fitness professional should always refer to an RD. Fitness and nutrition go hand in hand, but knowing scope of practice is important.

The Long Game
We’ve all seen the marketing tactics of fitness gimmicks showing how to get “shredded” or “6-pack abs” in 30 days. The before and after pictures may be convincing, but often these images are fabricated and fake. These “fitness programs” are scams that abuse the general public’s ignorance on the subject of health and fitness, despite countless studies that have proven that fitness isn’t an “overnight” sensation.
Carl Foster, an exercise physiologist at the University of Wisconsin, decided to run a study to determine if any results were actually measurable in a six week fitness program.
The plan was to photograph and measure volunteers between the ages of 18 – 40 wearing skimpy bathing suits and then randomly assign them to one of three groups: cardiovascular exercise, weight lifting or control. Six weeks later, they would be photographed and measured again.
Results were not surprising. Objective measurements, like weight and percentage of body fat, waist size and the size of the bicep or thigh, did not change.
Clearly , the promises of these fitness gimmicks are for marketing purposes and not in the best interest of the client.
The only way to fight back against these tactics is by educating your clients and potential clients about their own fitness journey towards their unique goals.
