Should You (or Should You Not) Be Working Out on an Empty Stomach?

Should You (or Should You Not) Be Working Out on an Empty Stomach?

As the amount of fitness information available is getting bigger, the chances of being exposed to bad advice are also growing, creating more fitness myths than ever. Yet, one of the most debatable myths that has been out there forever is the myth of working out on an empty stomach.

It has been a prevailing thought for decades that you shouldn’t eat or drink prior to working out, and it seems that only recently the public has started questioning its accuracy.

“Fasted” versus “Fed”

The common belief of the effectiveness of the “hungry workout” isn’t unsupported; actual research backs it up. The British Journal of Nutrition[1] and the International Journal of Sports Nutrition and Exercise Metabolism both published studies that show data in favor of “fasted” as opposed to “fed” training when it comes to the percentage of fat lost per workout.[2]

Additionally, a study published in the European Journal of Applied Physiology shows that fasted training provides a better anabolic post workout response to weight training, meaning it provides a better environment for building lean mass.

Namely, the conclusions indicate that “prior fasting may stimulate the intramyocellular [stored fats] anabolic response to ingestion of a carbohydrate/protein/leucine mixture following a heavy resistance training session.”[3]

Moreover, by providing better absorption of the post workout meal nutrients, fasted training has the great potential to improve insulin sensitivity, and is, therefore, an important agent in the fat loss process.

As insulin sensitivity shows how easily fat and muscle cells in our body take in glucose, regulating insulin sensitivity helps lower the blood sugar levels, which is one of the most important factors in weigh loss. The Journal of Physiology published a study[4] that shows significantly greater insulin sensitivity improvement for the fasted training group as opposed to fed training group.

Finally, fasted training proved beneficial to endurance performance. In a study[5] published in the Journal of Strength and Conditional Research, ten professional cyclists maintained lean mass, lowered fat mass, and maintained performance.

Why fed training is better?

However, there is another side to the story that trumps the beliefs of efficacy of fasted workouts. As sports dietetics specialist Kelly Pritchett, Ph.D., R.D. explains, while the body’s response to a high-intensity fasted workout is to burn glycogen, the stored up carbohydrates, eventually, the body starts to adjust to the new system and starts storing fat from the next meal and burning less calories in order to compensate.[6]

Additionally, a study[7] published in the American Journal of Clinical Nutrition shows no benefits of fasting, since longer periods of avoiding food showed a decrease in resting metabolic rates (calories burned per unit of time, a day usually.)

What’s more, fed training actually helps reduce appetite later in the day, as a study[8] in the journal Appetite shows. Whereas both fed and fasted training participants were expanding the same amount of energy throughout the day, the fed training participants experienced lessened appetite later on, which means less snacking or overeating later in the day, which is great news for anyone who wants to lose weight.

Although it may seem (according to scientific data) that fasted exercise provides better results, later and more extensive research shows the opposite is true.

As far as the fat burning capacity of fasted training is concerned, while it is accurate to some point, on the other hand it is proven to be counterproductive.

Namely, throughout the course of a high-intensity fasted workout, having no more fat to burn, the body starts to burn muscle instead. As another study[9] published in the European Journal of Physiology shows, during high-intensity training, without prior eating, the body relies on burning muscle proteins for energy, which is certainly an unwanted scenario for both professional athletes, and people who are just trying to shed some weight and feel better.

Another important benefit of fed training is that it gives you the ability to improve at a steady rate, which is impossible to achieve through a fasted workout regimen, as a study[10] from the Journal of Science and Medicine in Sport shows. Being able to push yourself a little bit further each time, and outperform your previous training, isn’t feasible with fasted training since your body lacks the energy to rely on for additional strength. By eating a light meal before your workout, your body will be provided with enough energy to help you perform a little better each time.

As the study concludes, “meal ingestion prior to daily exercise can modify some of the exercise training-induced adaptations normally seen with endurance training compared to when daily exercise is undertaken in the overnight-fasted state.”

How Fed training affects fat loss

When it comes to burning fat, the results are more favorable for the fed training method. As another study[11] in the International Journal of Sport Nutrition and Exercise Metabolism shows, physical activity after a light meal is far more effective for fat loss.

The study analyzed the effect on oxygen consumption (VO2) and substrate utilization (how our bodies burn fats and carbs), estimated by the respiratory-exchange ratio (RER) in eight young healthy men who were exposed to the same moderate-intensity workout. The results showed that breakfast increased both VO2 and RER significantly, and more importantly, the difference was still significant 24 hours after exercise. This means that fed training increases lipid utilization (the breaking down of fat cells), which is essential for weight loss.

Another study[12] in the Journal of the International Society of Sports Nutrition has managed to completely refute the belief that fat loss is much faster throughout fasting training, as the results showed no significant difference in weight loss between women who ate a meal-replacement shake before working out and those who performed training without any meal.

Conclusions

All research considered, a fed workout actually has more scientifically proven benefits to overall health, fitness, weight loss, and workout performance, as opposed to fasted training. It may seem like fasted training aids in body fat loss, but in the long run, it actually has counterproductive effects, as the body starts to store fat and burn less calories as a precaution.

Additionally, the studies show far greater and longer effects on burning body fat with fed training than those of a fasted. Moreover, the decreased appetite shown in groups who performed fed training is another reason for people who want to shed some weight to enjoy a light meal before a workout in order to prevent later cravings.

Finally, for reaching new higher goals in fitness and training, a fed workout is again a much more productive option, since the calories provide enough energy for extra effort.

Why Is Goal Setting Important to a Truly Fulfilling Life?

Why Is Goal Setting Important to a Truly Fulfilling Life?

In Personal Development-speak, we are always talking about goals, outcomes, success, desires and dreams. In other words, all the stuff we want to do, achieve and create in our world.

And while it’s important for us to know what we want to achieve (our goal), it’s also important for us to understand why we want to achieve it; the reason behind the goal or some would say, our real goal.

Why is goal setting important?

1. Your needs and desire will be fulfilled.

Sometimes when we explore our “why”, (why we want to achieve a certain thing) we realize that our “what” (our goal) might not actually deliver us the thing (feeling, emotion, internal state) we’re really seeking.

For example, the person who has a goal to lose weight in the belief that weight loss will bring them happiness, security, fulfillment, attention, popularity and the partner of their dreams. In this instance, their “what” is weight-loss and their “why” is happiness (etc.) and a partner.

Six months later, they have lost the weight (achieved their goal) but as is often the case, they’re not happier, not more secure, not more confident, not more fulfilled and in keeping with their miserable state, they have failed to attract their dream partner.

After all, who wants to be with someone who’s miserable? They achieved their practical goal but still failed to have their needs met.

So they set a goal to lose another ten pounds. And then another. And maybe just ten more. With the destructive and erroneous belief that if they can get thin enough, they’ll find their own personal nirvana. And we all know how that story ends.

2. You’ll find out what truly motivates you

The important thing in the process of constructing our best life is not necessarily what goals we set (what we think we want) but what motivates us towards those goals (what we really want).

The sooner we begin to explore, identify and understand what motivates us towards certain achievements, acquisitions or outcomes (that is, we begin moving towards greater consciousness and self awareness), the sooner we will make better decisions for our life, set more intelligent (and dare I say, enlightened) goals and experience more fulfilment and less frustration.

Advertising

We all know people who have achieved what they set out to, only to end up in the same place or worse (emotionally, psychologically, sociologically) because what they were chasing wasn’t really what they were needing.

What we think we want will rarely provide us with what we actually need.

3. Your state of mind will be a lot healthier

We all set specific goals to achieve/acquire certain things (a job, a car, a partner, a better body, a bank balance, a title, a victory) because at some level, most of us believe (consciously or not) that the achievement of those goals will bring us what we really seek; joy, fulfilment, happiness, safety, peace, recognition, love, acceptance, respect, connection.

Of course, setting practical, material and financial goals is an intelligent thing to do considering the world we live in and how that world works.

But setting goals with an expectation that the achievement of certain things in our external, physical world will automatically create an internal state of peace, contentment, joy and total happiness is an unhealthy and unrealistic mindset to inhabit.

What you truly want and need

Sometimes we need to look beyond the obvious (superficial) goals to discover and secure what we really want.

Sadly, we live in a collective mindset which teaches that the prettiest and the wealthiest are the most successful.

Some self-help frauds even teach this message. If you’re rich or pretty, you’re happy. If you’re both, you’re very happy. Pretty isn’t what we really want; it’s what we believe pretty will bring us. Same goes with money.

When we cut through the hype, the jargon and the self-help mumbo jumbo, we all have the same basic goals, desires and needs:

Joy, fulfilment, happiness, safety, peace, recognition, love, acceptance, respect, connection.

Advertising

Nobody needs a mansion or a sport’s car but we all need love.

Nobody needs massive pecs, six percent body-fat, a face lift or bigger breasts but we all need connection, acceptance and understanding.

Nobody needs to be famous but we all need peace, calm, balance and happiness.

The problem is, we live in a culture which teaches that one equals the other. If only we lived in a culture which taught that real success is far more about what’s happening in our internal environment, than our external one.

It’s a commonly-held belief that we’re all very different and we all have different goals — whether short term or long term goals. But in many ways we’re not, and we don’t; we all want essentially the same things.

Now all you have to do is see past the fraud and deception and find the right path.
