Fit Fashion: The Smart Belt

Source
There used to be a time when your belt or pants would get tight and you’d think, “I’d better cut back.” Now, there’s a belt out there to keep our waistlines in check.  “Belty” is a motorized belt that automatically adjusts to the user’s waist depending on how much they have eaten (and also can track activity).  It then syncs via Bluetooth to an app on the user’s smartphone.  It was recently released during the Consumer Electronics Show this past January.  The maker Emiota, a French company, has not released a sale date.  Looks like you’re stuck with your FitBit for a while longer!

Are 5 Minute Workouts Hype?

What sounds like a late night TV infomercial might actually be true.   Research is showing that short bouts of exercise a few times per day can do a whole host of things.  From reducing blood pressure to blood sugars, research is showing that intensity versus duration plays a role. 

Researchers looked at participants (read the full study published in Diabetologia here) who exercised for thirty minutes continuously per day versus exercise ‘snacks’ or higher intensity exercise for a shorter duration (about ten minutes) before a meal.  Exercise is known to lower blood sugar so any bit is beneficial, but those that had the “exercise snacks” per meal had lower blood sugar throughout the day.  Another key point to consider is the level of fitness of the individual. 

The Journal of the American College of Cardiology published research regarding jogging as little as 5 minutes per day may increase one’s lifespan.  There is also research for a one-minute workout which has 3 intense 20 second intervals. 

So…there is a catch to all of this.  The exertion in all of these short workouts is intense.  The goal is to push the participants out of their comfort zone.  The psychological benefits of exercise range from improving brain health for individuals at risk for Alzheimer’s disease to buffering against stress and depression.

All In A Day's Nutrition

It is a well-known fact among dietitians that the general public fails to meet nutrition recommendations. Athletes, whose endurance and performance are critically affected by nutritional status and food intake, are no exception.  Surprisingly, studies have consistently shown that athletes, male and female, adolescent to collegiate to elite level, and across various athletic activities, all consistently under-consume carbohydrate foods and consume more than necessary levels of protein and fat. Additionally, intake of calcium, iron, B-vitamins, vitamin D and Vitamin A fall short of recommendations. 1, 2, 3

Most athletes seek to perform at their greatest level, yet after successive daily training sessions, this inadequacy and imbalance can lead to significant decreases in energy levels and athletic performance.  Studies have shown that most athletes have inadequate nutrition knowledge, another contributing factor; specifically, athletes are unaware of specific carbohydrate needs, carbohydrate use in the body, vitamin storage, protein (and its relation to muscle gain vs. energy), and low-fat and weight loss diets. 4 Fortunately, for the athlete who wants to perform at his/her best, intervention studies have shown that with proper knowledge and guidance, athletes increase nutrition knowledge and self-efficacy and thus make positive dietary changes which can increase or improve performance. 5, 6

It’s not enough to give an athlete a daily carbohydrate, protein, calorie and fat number to reach, based on the recommendations in the Nutrition and Athletic Performance Position Paper  from the Academy of Nutrition and Dietetics, the American College of Sports Medicine and the Dietitians of Canada 7.   

It is difficult for an athlete to translate those numbers into real food choices within a daily food plan.  What does 1.2 to 1.7 g/kg protein, 6 to 10 g/kg carbohydrate and 20-35% fat (intake from total calories) really look like?  

Below is a visual representation and breakdown of what one day’s worth of food looks like for a 140-pound, very active, 20-year-old female athlete, based on the aforementioned recommendations (2,880 calories, 384-640g carbohydrate, 77-109g protein, 42-49g fat).  It’s a lot of food and it’s a lot of carbohydrate.  

Remember, most athletes consume enough protein (optimizing protein intake by spreading it throughout the day, however, is more of a challenge but that’s another blog post) but most athletes under-consume carbohydrates.  Coincidentally, in writing this meal plan, it was most challenging to reach target carbohydrate levels—reaching protein was easy.  Looking at it this way, it is easy to see why many athletes themselves are finding it difficult to meet carbohydrate needs, especially in today’s carbo-phobic society, when even as a nutrition professional, I find that most challenging, too.   

Many foods chosen in this meal plan were selected because they provide high doses of nutrients that are typically lacking in an athlete’s diet—calcium, iron, Vitamins A and D, B-vitamins and antioxidants.  Please keep in mind that a larger athlete, such as a 200-pound active male, will have much higher needs (closer to 5,000 calories, 540-900g carbohydrate, 108-153g protein and 111–167g fat).

Nutrition Bites: Is Healthy Obese an Oxymoron?

Research from the Journal of the American College of Cardiology indicates otherwise.  

There are individuals who are obese yet workout and make some healthy food choices, these folks initially have healthy blood lipids, blood sugars, and other vitals and lab work.  

However, those who maintain their weight (obesity) over a period of time (20 years) have increasing triglycerides, cholesterol, blood pressure, glucose, and insulin resistance.  

Lead author, Joshua A. Bell, a doctoral candidate at University College London reports, “healthy obesity’ is quite a misleading term.  It sounds safe, but we know that it’s only healthy in a relative sense. The healthy obese become unhealthy and progress into the highest risk group. This is a real challenge to the idea that the obese can be healthy in the long term.”

Fending off Sarcopenia in Aging Adults

Good nutrition throughout the life cycle can ward off illness and keep one healthy into their golden years.  We are entering an era where the Baby Boomers are retiring and continuing to stay active.

Older adults make up a greater percentage of the American population than ever before (1). Sarcopenia, or the loss of muscle mass with age, is a common condition faced by this age group. Sarcopenia alone can impact an older adult’s quality of life and limit his or her ability to complete activities of daily living (think basic self-care tasks). Furthermore, when combined with obesity, sarcopenia may increase the risk of insulin resistance (2). Therefore, it is important that we, as nutrition professionals, promote nutritional strategies shown to maintain muscle mass throughout the lifespan. Together, nutrition therapy and exercise can improve body composition with age and help prevent the deterioration of skeletal muscle mass and function.  

From a nutrition perspective, adequate protein intake is essential. However, there is more to it than just overall protein intake throughout the day. Research has shown that older adults have a blunted muscle protein synthesis response following the intake of 20 grams of protein or less (3,4). However, young and old muscles have similar rates of muscle protein synthesis following the ingestion of 30 grams of protein (5).  Because of this, the amount of protein eaten at each meal is especially important in older adults. In a 2009 review, Paddon-Jones et al. modeled the typical pattern of protein intake versus the optimal pattern of protein intake in older adults (see picture below) (6).




With this information in mind, we should encourage 25-30 grams of protein at each meal in order to promote maximal protein synthesis in older adults. If this recommendation cannot be met (because of a lack of appetite or a physical disability), older adults may also benefit from additional protein or essential amino acid supplements between meals (>10 g essential amino acids) (7). Let’s keep Grandma moving!
