24 INSIDER November/December 2018 other factors such as an increased protein or fat intake or restriction of carbohydrate." High Protein Some diets including low-carb (e.g., Atkins) and paleo feature higher intakes of protein foods like eggs and meats. Protein is the most satiating macronutrient and drives the building of lean body mass (LBM). In its position stand on diet and body composition, ISSN noted when protein intakes are comparable, there don't tend to be signifi cant fat loss differences between keto diets and non-keto diets. They further reported when high-protein diets go as high as 4.4 g/kg bodyweight per day, there is no additional signifi cant change in body composition compared to a regular high-protein diet (about 1.8 g/kg/d). High-protein diets, intakes of 1.6 g/kg/d and higher, are common in sports nutrition. Protein supplements, functional foods and beverages, snacks and other convenient forms are incredibly popular. High-protein diets feature meat and dairy, including eggs. From milk, whey protein is fast acting and the overall most popular choice before and after exercise, whereas casein is a slower acting dairy protein that is ideal for overnight supplementation. Chicken is hugely popular with athletes, and a protein isolate powder, CHiKPRO from International Dehydrated Foods (IDF), offers athletes an opportunity to get this favored protein in novel forms including soup, pasta and snacks. For high-protein dieters, several supplements can boost the effectiveness of ingested protein. An amylopectin- chromium combination (as Velositol ® , from Nutrition 21) increases insulin and protein synthesis. A combination of the amino acids alanine and glutamine (as Sustamine ® , from Kyowa Hakko) is also touted for its ability to help dietary protein increase muscle protein synthesis (MPS), the process of making new muscle, and inhibit muscle protein breakdown (MPB). BCAAs are increasingly popular as a protein complement to boost leucine levels, as leucine has been highlighted as a limiting factor or trigger for MPS. Leucine and its metabolite HMB (beta-hydroxy- beta-methylbutyrate) spark MPS via the mammalian target of rapamycin (mTOR) pathway, which is also activated by another dietary ingredient: phosphatidic acid. Sports Nutrition: Athletes with Specialized Diets Scan Here At the Heart of Weight Loss: Fat or Muscle? by Susan Hewlings and Doug Kalman, Ph.D., R.D. It is no secret that body weight status directly impacts and affects health and quality of life. Overweight and obesity is a public health crisis for developed countries across the globe. With approximately 60 percent of the population of the United States dealing with weight issues, it should come as no surprise that there are many programs and products marketed as solutions for weight balance and appearance. The public is constantly overwhelmed by diet information, food planning suggestions, weight loss products and societal pressures to lose weight. It is true that many people lose weight, but very few keep it off. Perhaps the constant barrage continues because, despite decades of talking about it, our attempts to address the obesity epidemic have led to less than promising long-term results. One reason for this may be a lack of focus on what contributes to weight loss—fat or muscle. Just losing pounds on the scale is clearly not the answer; focusing on where those pounds come from may be the missing link to the weight loss solution. The most important piece of the weight loss puzzle is where the weight is lost (fat or muscle) if sustainable long-term weight loss and health are the goals. This is because a loss of lean body mass can be very detrimental to health and long-term weight loss maintenance. So, whether trying to lose a lot of weight or just obtain a leaner physique, maintaining lean body mass (LBM) is the key. Kalman and Hewlings are co-presenters in the upcoming SupplySide West Workshop "Helping Active Consumers Stay Lean and Fit," where they will discuss some popular diet strategies that have been effective for weight loss and look at how they infl uence body composition. They will also look at some popular supplements and how they may help with augmenting fat loss or lean muscle retention during weight loss. The workshop is scheduled for Wednesday, Nov. 7 at 9 a.m. supplysideshow.com Doug Kalman is vice president of scientifi c affairs for Nutrasource (Nutrasource.ca), co-founder of the International Society of Sports Nutrition (ISSN, SportsNutritionSociety.org) and co-editor of the Journal of ISSN.
