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.

35 Anniversary Ideas to Bring You Closer Together

35 Anniversary Ideas to Bring You Closer Together

Every mature relationship has had a less-than-memorable anniversary. Maybe one of you forgot, or both of you got busy with work, kids, family issues, or something else. Whatever happened, the day came and went without fanfare. And neither of you seemed to notice or much care.

But for the health of any relationship, it’s important to make important days feel special. Anniversaries offer the wonderful opportunity to relive beautiful memories, practice gratefulness for your partner, and to show your love and strengthen your bond. Make this year’s anniversary with your significant other something special  — one that will bring you closer together.

While you enjoy your chosen anniversary activity, be sure to keep a positive attitude and make your partner happy too on that day. Leave all arguments and day to day detail behind. Just celebrate your relationship. Whether you’re going to spend the day together at home, getting away, or having a wild and crazy new experience together, you can have your best anniversary yet!

If You’re Staying In

  1. Spend an evening with no technology, just the two of you and maybe a board game. It’s hard to keep ourselves away from our computers and smartphones long enough to have a meaningful conversation. Make a rule not to use your tech and you’ll rekindle your relationship!
  2. Make wine or beer together. If you enjoy drinking together, this is a fun activity to try together. Just remember to buy the necessary equipment ahead of time.
  3. Learn something new about each other. With an open mind, try asking some of the New York Times’ 36 questions that lead to love. They’ll help spark intimacy and will lead to some really honest moments.
  4. Have a lazy day. Breakfasts in bed, spend all day in bed talking and napping. Follow breakfast with champagne and dessert! If you feel like getting more active, cook together or play some games. Here’re some simple breakfast ideas for you.
    • Learn to dance at home. This is best for those active couples who work out together and also enjoy learning something new together. Just go on Youtube to find any music with dance tutorials and learn together.
    • Visit model homes or open houses and plan your dream home.
    • Have a special dessert – champagne and chocolate covered strawberries. Having an unusual treat makes a day feel extra special. If you want to make the dessert really special, try these tasty dessert recipes.
    • Create a playlist of your favorite songs as a couple. Choose songs that tell your story, and songs that you bonded over throughout your relationships. Here’re some love songs ideas for your inspirations.
      • Write your love story. Write it together or ave each of you write your own and then bring them together in an interesting, both sides of the story format.
      • Get a fondue pot. Fondue is a fun way to enjoy melted cheeses (for savory items) and melted chocolate (for sweeter treats).
      • Decorate! Turn your home into a dressed-up french cottage, a sophisticated restaurant, or simply with flowers. The different ambience will immediately change the feel of your home and make it feel like a staycation.
        • Talk about the future together. It might sound simple and everyday, but imagining how you want to spend your retirement together, or planning future trips can be exciting and romantic.

        If You Want to Get Away

        1. Take a day trip together to your favorite spot. If you live in a city, it can be incredibly refreshing to get away for an afternoon and drink in the outdoors.
        2. Go on a scenic drive and stop at a wine and cheese bar. Or, if you’re lucky enough to have lots of options where you live, try a brewpub. There are tons of small craft breweries with fantastic food options too.
        3. Go camping. Relatively affordable and, if the weather’s right, beautiful and romantic.
          • Take an overnight backpacking trip. For the more adventurous couples, backpacking is an even more intense way to challenge yourself physically while becoming one with nature.
          • Take a wine tasting tour. If you live on the West Coast or in the Northeast, take a drive to the nearest winery. Many offer relatively inexpensive tastings and deals if you purchase a certain amount.
          • Take a scenic train trip. Taking the train means less stress traveling: nobody has to drive, you don’t have to stop for breaks every few hours, and you can sleep if you need to!
          • Save up for a destination vacation. What better time than your anniversary to enjoy the beach at a beautiful resort?
          • Explore a new city. Whether you’re on a budget or have a lot saved up, you can have a great time just exploring an unfamiliar town.
          • Rent a cabin for a weekend away, in the woods or next to a lake or ocean. If you like the outdoors but can only take so much nature, try glamping.
            • Go on a retreat. Yoga retreats, meditation retreats, beautiful natural surroundings … they’re all the rage. Search for centeredness and calm with your partner.
            • Spend a day at a food festival. Many cities have fun and affordable food festivals, occasionally based on a theme. Check out your town’s (or a nearby city) calendar for inspiration!

            New & Exciting Experiences

            1. Go spelunking. Dark, damp, and utterly exciting!
            2. Go on a hot air balloon ride. Because the basket is relatively small, this can be a romantic and deeply personal – and yet thrilling –
              experience.
              • Try sky diving. If you and you S.O. are real thrill-seekers, sky diving can really push you to the edge!
              • Explore the underwater world by snorkeling or scuba diving. This may take you far away from where you normally live and work, which is an added bonus.
              • Experience white water rafting.
              • Drive or hike to the highest spot nearby for a new view of the world. America has tons of beautiful mountains where challenging hikes (or drives) can deliver breathtaking views.
              • Take a craft or cooking class. Up your craft skills or food  making skills, and enjoy something new!
                • Take a wine and painting class today. These classes are easily found these days and even a beginning painter can create a nice painting. Challenging but relaxing, fun, and you get to go home with some artwork!
                • Learn to salsa dance. Dancing is a fantastic way to actively get closer and coordinate physically with one another.
                  • Visit a nearby festival you’ve always wanted to go to. Have fun and let go with fellow audience-members!
                  • Spend the day at an amusement park together. Laugh and carry on like teenagers.
                  • Meet new people! At a restaurant, concert, or class, make it a point to meet new friends. Striking up conversation with someone you don’t know – but with whom you have shared interests – can be an adventurous and rewarding experience.

                  Whether your budget is big or small, and whether you have a little or a ton of time together, focus on each other. There are tons of options, in terms of location, level of physical activity, and cost. You can make the day special in a way that’s right for you!
