Kai FusserKai Fusser, MS

Kai Fusser, M.S. was first introduced to the world of fitness when he was just six. His father made him a 5-pound dumbbell, fabricating it from materials at his workplace and wrapping it in electrical tape. Kai hasn’t stopped lifting weights and working out since.

But, to Kai, being physically fit is more than just working out and building muscle. It’s strengthening the muscles necessary to perform particular moves; and this is where Kai finds the marriage between fitness and golf a thing of beauty. Hitting a golf ball requires the intricate movement of muscles; and strengthening those muscles through specific exercises is a science Kai enjoys exploring … and the successes he has experienced have been great.

Kai has helped Hall of Fame golfers reach new heights, has helped turn average golfers into championship golfers, and continues to help golfers of all abilities – male and female – add power, distance, and control to their games. In fact, one of Kai’s most famous pupils – Annika Sorenstam – was looking to add to her incredible arsenal.

Annika had already established herself as the top female golfer in the world. But she wanted more distance, and more control. After meeting Kai at a local YMCA, she was convinced his methodology was the right system to follow. Less than 6-months later, Annika had gained more than 20-yards with her driver, and improved her accuracy. The result? In 2002, Annika put together one of the greatest seasons in the history of golf, winning 13 tournaments. In 2003, she played against the men at Colonial and had no problem keeping up with them.

Overall, golfers who have worked with Kai, including, Graeme McDowell, Jonas Blixt, Anna Nordqvist, Karen Stupples and Batrice Recari, have won more than a dozen majors and over 100 tournaments worldwide. And, Kai has helped professional and amateur athletes in other sports as well. In fact, water skiers and wake boarders whom Kai has worked with have also won more than 100 championships including several in the X-Games and Gravity-Games. Former NBA All-Star Grant Hill and 1998 Indianapolis 500 Champion Eddie Cheever also turned to Kai for fitness.

Today, Kai runs the golf fitness program at the Annika Academy ™ and helps all golfers improve their game without ever placing a golf club in their hands. He does it through a fitness routine that is proven and tested to work. Featured in such publications as Golf Digest, Golf Magazine, the USA Today, Golf Fitness Magazine, and more. Kai’s philosophy is “efficiency through perfect movement” … and in the golf swing, this means, it’s the sum of all muscles in our body working together at the right time, and the right volume. This ensures great efficiency as the loads on the body are distributed throughout the whole system, every muscle does its part, and they all help each other.

Julie Donnelly is a Deep Muscle Massage Therapist with 20 years of experience specializing in the treatment of chronic joint pain and sports injuries. She has worked extensively with elite athletes and patients who have been unsuccessful at finding relief through the more conventional therapies.

She has been widely published, both on – and off – line, in magazines, newsletters, and newspapers around the country. She is also often chosen to speak at national conventions, medical schools, and health facilities nationwide.

Her training began as a massage therapist, licensed in the State of New York where the initial requirement was 650 hours of classroom study in topics such as Anatomy & Physiology, Kinesiology, Pathology of Muscles, Medical Massage, and Eastern Theory. She spent hundreds of hours focusing on an understanding of why muscles cause pain that may be far removed from the actual source of the problem, and why conditions such as carpal tunnel syndrome exist.

She has also received advanced training from a doctor of osteopathy, a physical therapist, a therapeutic massage therapist and from other professionals involved with just about every form of muscular training. This diverse exposure widened the scope of her practice far beyond spa massage and was the solid foundation of everything she does now. Unlike relaxing massage which has its own benefits, her work focuses on the deep muscles that hold joints bound, preventing full range-of-motion and causing chronic joint pain.

In 1989 she began working with individuals who were suffering from chronic joint pain and sports injuries. She quickly began working with serious athletes, many of them endurance athletes that compete in races with such grueling events as the Century Marathons (actually running 100 miles!), the Race Across America (RAAM) where an athlete cycles from San Diego to Atlantic City, NJ in just 8 days, and Ironman Triathlons which combine 2 ½ miles swimming, 112 miles cycling and then finishing off with 26.2 miles running.

From her work with endurance athletes, serious local athletes, and people who were suffering from a wide assortment of chronic joint pains, the Julstro techniques of self-treatment developed. Expanding her teaching with the addition of the self-treatment concept really separates her from the majority of her peers. She found that as she began to teach people how to help-themselves they could continue their therapy outside of their session with her.

In 1993 she opened her first Julstro Muscular Therapy Center. Her message to her clients is this: “When you come to visit me, I’ll work on your muscles, release the knots that are holding the muscles short and putting pressure on your nerves and joints, and then I’ll teach YOU how to do simple treatments that will help you when you are at home. That is my promise to you!”

But if you cannot travel, she has made her self-treatment techniques available worldwide by way of http://www.julstro.com where you will find information on the Julstro™ Self–Treatment System. You may also be interested in her series of Pain–Free Books which share the Julstro™ techniques in a clear, concise manner.

A Low Carb Diet and Weight Loss

Posted January 15, 2019 by Dr. Steve Chaney

Do Low-Carb Diets Help Maintain Weight Loss?

Author: Dr. Stephen Chaney

 

low carb dietTraditional diets have been based on counting calories, but are all calories equal? Low-carb enthusiasts have long claimed that diets high in sugar and refined carbs cause obesity. Their hypothesis is based on the fact that high blood sugar levels cause a spike in insulin levels, and insulin promotes fat storage.

The problem is that there has been scant evidence to support that hypothesis. In fact, a recent meta-analysis of 32 published clinical studies (KD Hall and J Guo, Gastroenterology, 152: 1718-1727, 2017 ) concluded that low-fat diets resulted in a higher metabolic rate and greater fat loss than isocaloric low-carbohydrate diets.

However, low-carb enthusiasts persisted. They argued that the studies included in the meta-analysis were too short to adequately measure the metabolic effects of a low-carb diet. Recently, a study has been published in the British Medical Journal (CB Ebbeling et al, BMJ 2018, 363:k4583 ) that appears to vindicate their position.

Are low carb diets best for long term weight loss?

Low-carb enthusiasts claim the study conclusively shows that low-carb diets are best for losing weight and for keeping it off once you have lost it. They are saying that it is time to shift away from counting calories and from promoting low-fat diets and focus on low-carb diets instead if we wish to solve the obesity epidemic. In this article I will focus on three issues:

  • How good was the study?
  • What were its limitations?
  • Are the claims justified?

 

How Was The Study Designed?

low carb diet studyThe investigators started with 234 overweight adults (30% male, 78% white, average age 40, BMI 32) recruited from the campus of Framingham State University in Massachusetts. All participants were put on a diet that restricted calories to 60% of estimated needs for 10 weeks. The diet consisted of 45% of calories from carbohydrate, 30% from fat, and 25% from protein. [So much for the claim that the study showed low-carb diets were more effective for weight loss. The diet used for the weight loss portion of the diet was not low-carb.]

During the initial phase of the study 161 of the participants achieved 10% weight loss. These participants were randomly divided into 3 groups for the weight maintenance phase of the study.

  • The diet composition of the high-carb group was 60% carbohydrate, 20% fat, and 20% protein.
  • The diet composition of the moderate-carb group was 40% carbohydrate, 40% fat, and 20% protein.
  • The diet composition of the low-carb group was 20% carbohydrate, 60% fat, and 20% protein.

Other important characteristics of the study were:

  • The weight maintenance portion of the study lasted 5 months – much longer than any previous study.
  • All meals were designed by dietitians and prepared by a commercial food service. The meals were either served in a cafeteria or packaged to be taken home by the participants.
  • The caloric content of the meals was individually adjusted on a weekly basis so that weight was kept within a ± 4-pound range during the 5-month maintenance phase.
  • Sugar, saturated fat, and sodium were limited and kept relatively constant among the 3 diets.

120 participants made it through the 5-month maintenance phase.

 

Do Low-Carb Diets Help Maintain Weight Loss?

low carb diet maintain weight lossThe results were striking:

  • The low-carb group burned an additional 278 calories/day compared to the high-carb group and 131 calories/day more than the moderate-carbohydrate group.
  • These differences were even higher for those individuals with higher insulin secretion at the beginning of the maintenance phase of the study.
  • These differences lead the authors to hypothesize that low-carb diets might be more effective for weight maintenance than other diets.

 

What Are The Pros And Cons Of This Study?

low carb diet pros and consThis was a very well-done study. In fact, it is the most ambitious and well-controlled study of its kind. However, like any other clinical study, it has its limitations. It also needs to be repeated.

The pros of the study are obvious. It was a long study and the dietary intake of the participants was tightly controlled.

As for cons, here are the three limitations of the study listed by the authors:

#1: Potential Measurement Error: This section of the paper was a highly technical consideration of the method used to measure energy expenditure. Suffice it to say that the method they used to measure calories burned per day may overestimate calories burned in the low-carb group. That, of course, would invalidate the major findings of the study. It is unlikely, but it is why the study needs to be repeated using a different measure of energy expenditure.

#2: Compliance: Although the participants were provided with all their meals, there was no way of being sure they ate them. There was also no way of knowing whether they may have eaten other foods in addition to the food they were provided. Again, this is unlikely, but cannot be eliminated from consideration.

#3: Generalizability: This is simply an acknowledgement that the greatest strength of this study is also its greatest weakness. The authors acknowledged that their study was conducted in such a tightly controlled manner it is difficult to translate their findings to the real world. For example:

  • Sugar and saturated fat were restricted and were at very similar levels in all 3 diets. In the real world, people consuming a high-carb diet are likely to consume more sugar than people in the other diet groups. Similarly, people consuming the low-carb diet are likely to consume more saturated fat than people in the other diet groups.
  • Weight was kept constant in the weight maintenance phase by constantly adjusting caloric intake. Unfortunately, this seldom happens in the real world. Most people gain weight once they go off their diet – and this is just as true with low-carb diets as with other diets.
  • The participants had access to dietitian-designed prepared meals 3 times a day for 5 months. This almost never happens in the real world. The authors said “…these results [their data] must be reconciled with the long-term weight loss trials relying on nutrition education and behavioral counseling that find only a small advantage for low carbohydrate compared with low fat diets according to several recent meta-analyses.” [I would add that in the real world, people do not even have access to nutritional education and behavioral modification.]

 

low carb diet and youWhat Does This Study Mean For You?

  • This study shows that under very tightly controlled conditions (dietitian-prepared meals, sugar and saturated fat limited to healthy levels, calories continually adjusted so that weight remains constant) a low-carb diet burns more calories per day than a moderate-carb or high-carb diet. These findings show that it is theoretically possible to increase your metabolic weight and successfully maintain a healthy weight on a low-carb diet. These are the headlines you probably saw. However, a careful reading of the study provides a much more nuanced viewpoint. For example, the fact that the study conditions were so tightly controlled makes it difficult to translate these findings to the real world.
  • In fact, the authors of the study acknowledged that multiple clinical studies show this almost never happens in the real world. These studies show that most people regain the weight they have lost on low-carb diets. More importantly, the rate of weight regain is virtually identical on low-carb and low-fat diets. Consequently, the authors of the current study concluded “…translation [of their results to the real world] requires exploration in future mechanistic oriented research.” Simply put, the authors are saying that more research is needed to provide a mechanistic explanation for this discrepancy before one can make recommendations that are relevant to weight loss and weight maintenance in the real world.
  • The authors also discussed the results of their study in light of a recent, well-designed 12-month study (CD Gardener et al, JAMA, 319: 667-669, 2018 ) that showed no difference in weight change between a healthy low-fat versus a healthy low-carbohydrate diet. That study also reported that the results were unaffected by insulin secretion at baseline. The authors of the current study noted that “…[in the previous study] participants were instructed to minimize or eliminate refined grains and added sugars and maximize intake of vegetables. Probably for this reason, the reported glycemic load [effect of the diet on blood sugar levels] of the low-fat diet was very low…and similar to [the low-carb diet].” In short, the authors of the current study were acknowledging that diets which focus on healthy, plant-based carbohydrates and eliminate sugar, refined grains, and processed foods may be as effective as low-carb diets for helping maintain a healthy weight.
  • This would also be consistent with previous studies showing that primarily plant-based, low-carb diets are more effective at maintaining a healthy weight and better health outcomes long-term than the typical American version of the low-fat diet, which is high in sugar and refined grains. In contrast, meat-based, low-carb diets are no more effective than the American version of the low-fat diet at preventing weight gain and poor health outcomes. I have covered these studies in detail in my book “Slaying The Food Myths.”

Consequently, the lead author of the most recent study has said: “The findings [of this study] do not impugn whole fruits, beans and other unprocessed carbohydrates. Rather, the study suggests that reducing foods with added sugar, flour, and other refined carbohydrates could help people maintain weight loss….” This is something we all can agree on, but strangely this is not reflected in the headlines you may have seen in the media.

The Bottom Line

 

  • A recent study compared the calories burned per day on a low-carb, moderate-carb, and high-carb diet. The study concluded that the low-carb diet burned significantly more calories per day than the other two diets and might be suitable for long-term weight control. If confirmed by subsequent studies, this would be the first real evidence that low-carb diets are superior for maintaining a healthy weight.
  • However, the study has some major limitations. For example, it used a methodology that may overestimate the benefits of a low-carb diet, and it was performed under tightly controlled conditions that can never be duplicated in the real world. As acknowledged by the authors, this study is also contradicted by multiple previous studies. Further studies will be required to confirm the results of this study and show how it can be applied in the real world.
  • In addition, the kind of carbohydrate in the diet is every bit as important as the amount of carbohydrate. The authors acknowledge that the differences seen in their study apply mainly to carbohydrates from sugar, refined grains, and processed foods. They advocate diets with low glycemic load (small effects on blood sugar and insulin levels) and acknowledge this can also be achieved by incorporating low-glycemic load, plant-based carbohydrates into your diet. This is something we all can agree on, but strangely this is not reflected in the headlines you may have seen in the media.
  • Finally, clinical studies report averages, but none of us are average. When you examine the data from the current study, it is evident that some participants burned more calories per hour on the high-carb diet than other participants did on the low carb diet. That reinforces the observation that some people lose weight more effectively on low-carb diets while others lose weight more effectively on low-fat diets. If you are someone who does better on a low-carb diet, the best available evidence suggests you will have better long-term health outcomes on a primarily plant-based, low-carb diet such as the low-carb version of the Mediterranean diet.
