 A Word from the Founder: The Global Rebirth of GPNiWhen I first founded the Global Performance Nutrition Institute (GPNi), I had a vision: to provide the highest-quality, evidence-based sports nutrition education and certification to professionals worldwide. I knew firsthand how difficult it was to access accurate, cutting-edge nutritional science in many parts of the world. There was a disconnect between what the science said, what professionals were being taught, and what athletes truly needed.Over the past three decades, my life’s work has been committed to bridging that gap. From my earliest days as a sports nutrition advocate in Australia, simply in love with fitness to founding multiple ventures in the nutrition space—including what is now NiHTEK, the world’s most innovative branded ingredient company in the non-dairy sports nutrition world—I have remained relentlessly focused on one mission: to elevate the standards of sports nutrition education globally. Why GPNi® is DifferentUnlike other online education companies entering the sports nutrition space, GPNi was built from the ground up by real-world practitioners with decades of hands-on experience. As the founder, together with all our PhDs, my lifelong commitment to performance nutrition is backed not only by a career in the trenches but also by formal collaboration with the most authoritative body in the field: the International Society of Sports Nutrition (ISSN). While others may claim to “offer it all,” few have the true scientific rigor, credibility, or global partnerships that GPNi brings to the table.What sets GPNi apart is our 360-degree approach to learning, blending academic excellence with practical coaching applications. We don’t just teach theory; we train you to lead in the real world. Our double certification model reflects that promise: earn your PNE Level 1 + ISSN-SNS to establish a solid foundation, or advance to the elite PNE Level 2 Master’s + ISSN-CISSN, the most recognized credential across universities, sports organizations, and fitness institutions worldwide. A New Era with NiHTEK®: Bridging Education & InnovationIn parallel with the evolution of GPNi, I have also been leading the development of NiHTEK, a science-driven ingredient company that pioneers next-generation functional proteins through advanced technologies, such as Molecular Protein Infusion (MPi™) and the Advanced Precision Hydrolysis (APH™) patent-pending technology.Why mention this here? I believe that education and innovation must go hand in hand. You also need to walk the talk in the world of sports nutrition, not just talk the talk, which almost all other sports nutrition online education companies do. Offer superficial knowledge with little experience in the field of actual sports nutrition. As NiHTEK breaks barriers with clinically superior, allergen-free, non-dairy protein isolates like NiHPRO®, we are also investing heavily in education around real science, real functionality, and product transparency. I am proud to be involved with both companies as the leaders of sports nutrition education globally with the GPNi, as well as sports nutrition innovative ingredients with NiHTEK.  Leading the Next GenerationWe are not here to follow trends—we are here to define the standards.This re-launch is our stake in the ground. GPNi® is now the most advanced global sports nutrition certification portal available anywhere, fully integrated with:ISSN-certified contentOngoing education credits with leading organisations such as NASM, ACE, and AFFA (CEUs) and more.Access to live global summitsPersonalized learner dashboardsA growing alumni community of real-world change-makersIt’s a new era of connected education, inspired application, and global nutrition leadership.So, I decided to build something better. GPNi became the world’s first and only globally accredited ISSN education partner, offering dual certification in foundational and advanced sports nutrition across multiple languages. A Platform Reimagined: Two Years of Building the FutureThis relaunch of GPNi is far more than a visual upgrade or technical enhancement. It is the culmination of nearly two years of intense development, thousands of hours, and many thousands of dollars invested to completely reinvent the way science-based nutrition is delivered and experienced.The new GPNi online portal is built from the ground up using modern educational architecture, including:Advanced LMS integration with seamless tracking and learner progressFull language adaptability across English, Japanese, and ChineseExpert video delivery with dynamic content updatesLive webinars and Q&A access with the world’s top nutrition scientistsStreamlined exams and digital credentials for real-time certificationEverything we’ve built is designed to ensure consistency, transparency, and a flawless experience for students, professionals, and coaches worldwide.This isn’t just an upgrade—it’s a transformation. Global Reach. Local Relevance. Scientifically Sound.At GPNi, we believe science is universal, but learning is local. That’s why we’ve gone to great lengths to offer high-level sports nutrition education in English, Japanese, and Chinese—the three most spoken languages in our industry.We are already educating students and coaches in more than 20 countries, with regional hubs and partnerships in:ChinaJapanSoutheast AsiaAustraliaEuropeNorth AmericaAnd this is just the beginning.The new platform enables GPNi to reach new corners of the globe, offering CISSN and SNS-certified pathways that are globally recognized yet delivered locally and culturally relevant. Thank You: To Every Student, Expert, and PartnerNone of this would be possible without the dedicated team of PhDs, industry educators, athletes, and students who’ve supported this journey. You’ve trusted us to deliver—and now, we deliver better than ever.Whether you're just starting your sports nutrition journey or you're a seasoned practitioner ready to elevate your credentials, I invite you to explore the all-new GPNi experience.Together, we are shaping the future of nutrition science—one student, one innovation, one breakthrough at a time. Limited-Time Launch Offer: Save Over 10%To celebrate the relaunch of the GPNi platform, we’re offering a special global promotion from August 1st to September 15th. Enrolments in:PNE Level 1 + SNS for just USD $791 (normally $879) or advance toPNE Level 2 Master’s + CISSN for just USD $1,338 (normally $1,487). This is your chance to save over 10% on the world’s most advanced sports nutrition education, with certification through both GPNi and the ISSN.

Intermittent Fasting (IF) diet is an eating pattern that involves periods of eating and periods of fasting. It has become very popular in recent years with athletes, celebrities and everyday people adopting the practice. Generally, this diet doesn’t specify what you should eat but instead deals with when.  In this article we will of how to best optimize it for best results in energy, fat loss and muscle gain. The period for the fast varies, but studies indicate that it usually lasts between 12 and 40 hours.  Depending on how strict the fast is, you can take calorie-free beverages and water during the fasting period, but solid foods and drinks that contain calories are not permitted.This article discusses various strategies for intermittent fasting, the pros and cons of this eating pattern, and makes recommendations based on scientific evidence.Is It The Miracle Diet?It must be pointed out prior, that there is often a big miss understanding that the “IF” diet is the miracle diet. It is not! Calories still matter so do macros.  If you are trying to lose weight using the IF method you still need to be in calorie deficit to do so, no different than no fasting and eating less.  To further optimize your fat loss it is also highly recommended to consume more protein also as protein helps keep you more full and has a slight thermogenetic effect on body fat.Different Strategies for Intermittent Fasting (IF)In its position paper on different forms of diets, the International Society for Sports Nutrition mentioned three different methods or subclasses of intermittent fasting. They are alternate-day fasting (ADF), whole-day fasting (WDF), and time-restricted (TRF).Whole-Day Fasting (WDF)Whole-day fasting involves picking a day or two where you fast in a week. Generally, on fasting days, there is a limit to the energy intake, with individuals usually expected to take in no more than 500 calories.  Like the other forms of intermittent fasting, WDF has been shown by multiple studies to cause weight loss and other health benefits. It is also referred to as the 5:2 diet because there is a 5-day eating window and a 2-day fasting window.Alternate-Day Fasting This is the most common kind of intermittent fasting, and it is the kind of intermittent fasting that has been greatly studied. ADF involves 24 hours of fasting followed by a 24-hour of eating. Like WDF, alternate-day fasting allows individuals to have some calorie intake on fasting days,  about 20-25% of what they would ordinarily require. ADF has also been shown to facilitate weight loss alongside other health benefits like improving brain powerTime-restricted feeding This involves a fasting period of about 16-20 hours followed by an eating period of 4-8 hours daily. TRF is well exemplified during the Ramadan fast for Muslims, which involves fasting from sunrise to sunset for about a month. It is not surprising that one of the significant consequences of TRF is weight loss, and studies have shown that TRF affects both fat mass and lean massDifferent studies have been conducted or reported by the ISSN on these intermittent fasting methods. These studies have also measured the effects of these intermittent fasting methods vis-a-vis other calorie regulation diets and methods.Here is a link to get complete details on these studies, and other information on other forms of diet plans: https://jissn.biomedcentral.com/articles/10.1186/s12970-017-0174-ybThe Pros and Cons of Intermittent FastingProsResearch has uncovered multiple benefits of intermittent fasting, and we discuss some of them below:1.It may contribute to weight loss and improve metabolic health.One of the fundamental reasons why people undergo intermittent fasting is for weight loss or to improve how the body performs metabolic functions. Research shows that intermittent fasting reduces the calories individuals need to maintain a particular weight, leading to weight loss. Furthermore, research has also uncovered that IF doesn’t necessarily have more significant effects than other calorie-reducing plans that do not require fasting.In one randomized trial for 116 participants published by the National Centre for Biotechnology Information, researchers concluded that time-restricted feeding led to weight loss.Read full details of the trial here: https://pubmed.ncbi.nlm.nih.gov/32986097/.Another trial published by the NCBI, which tested IF for 50 weeks, also reported weight loss, even though not more significant than weight loss obtained from eating calorie-restricting foods daily. This particular study made use of the 5:2 method of intermittent fasting.Read full details of the trial here: https://pubmed.ncbi.nlm.nih.gov/30475957/.Beyond the effect on the calories in the body, intermittent fasting may also cause weight loss by regulating the body’s hormones and stimulating the feeling of fullness while limiting the feeling of hunger. A study published by the NCBI on eleven overweight adults supports this.Read full details of the study here: https://pubmed.ncbi.nlm.nih.gov/31339000/.2.It has been linked with specific health benefits.Intermittent fasting has been linked to certain exciting health benefits, such as lowering blood pressure. A study with over 1000 participants published by the NCBI showed that prolonged fasting helped reduce blood pressure and helped to alleviate other emotional and physical health conditions.Read further details here: https://pubmed.ncbi.nlm.nih.gov/30601864/.Another significant health benefit that has been linked to intermittent fasting is the repair of damaged cells. A review published by the NCBI stated that food deprivation or fasting led to autophagy in a wide variety of tissues or organs. The study defined autophagy thus: “Autophagy functions to recycle building blocks and energy for cellular renovation and homeostasis, allowing cells to adapt to stress.”Read further details here: https://pubmed.ncbi.nlm.nih.gov/30172870/.Other health benefits that have been linked with intermittent fasting include the protection of brain health and the improvement of blood sugar.A study that shows how intermittent fasting protects brain health was published by the NCBI here: https://pubmed.ncbi.nlm.nih.gov/31804775/3.It usually fits right into your diet.Since IF does not stipulate anything for you to eat, you can easily adapt it to your current diet without the need to get extra food. Your current diet may work just fine, and you could simply complement it by adding any intermittent fasting methods.Cons1.You will have to deal with some hunger and frustration. Fasting for 24 hours or even 16 hours may mean that you will go to bed hungry on many days or deal with the day's activities while feeling hungry. This may not be convenient at first, and your body may not flow along with it all. When you consider that you can get similar results (regarding weight loss) without fasting, it even looks less appealing.2.It may affect your social life.Often,  bonding and even business deals happen over meals, and it will be increasingly socially awkward to be unable to eat at every other engagement or meeting. Furthermore, fasting affects your energy levels, and you may be unable to move as much as you want on “fasting days.” This could affect the amount of commitment you are able to give to social activities.3.Negative effects on moodScientific research has shown that people are more irritable and anxious when they have to fast or reduce calories. A study by the NCBI on the effects of fasting on healthy women supports this.Read full details here: https://pubmed.ncbi.nlm.nih.gov/27597946/.Recommendations for Intermittent Fasting DietIntermittent fasting is largely safe, with the main side effects being hunger and feelings of weakness. However, it becomes easier to manage and live with as you grow used to it. Here are some general recommendations that may help you as you consider IF:You can take water, coffee, and other calorie-free beverages on fasting days and hoursIf you have a medical condition, you should consult your doctor before trying intermittent fasting. Some conditions that may particularly require that you avoid IF are diabetes and low blood pressureTake in food rich in nutrients during your eating time, especially your protein intake.ConclusionIF is a unique way to diet, and the different methods allow individuals to pick what works best for them. However, it is essential to note that while it has positive health effects, if an individual has pre-existing health conditions, it could worsen them. The Body Transformation Nutrition Coach (BTNC®)To learn more about diets that work to maximize your own body transformation and your clients, check out the BTNC® certificate course by the GPNi®.  In the course we breakdown all the modern diets being used and recommended what can be used according to the latest science.  The BTNC® course is great for moderate level or beginners that want to understand the science and fundamentals to sports nutrition for fat loss and lean muscle gain.  Get ready to transform your body and your clients with the most up to date sports nutrition strategies today!Learn more about the BTNC® course here: https://thegpni.com/education/continued-education Available online and on-demand July 2022.Referenceshttps://www.healthline.com/nutrition/intermittent-fasting-guidehttps://www.healthline.com/nutrition/6-ways-to-do-intermittent-fasting#bottom-linehttps://pubmed.ncbi.nlm.nih.gov/27597946/https://jissn.biomedcentral.com/articles/10.1186/s12970-017-0174-yhttps://health.clevelandclinic.org/intermittent-fasting-4-different-types-explained/https://www.health.harvard.edu/heart-health/not-so-fast-pros-and-cons-of-the-newest-diet-trendhttps://www.insider.com/intermittent-fasting-good-or-bad-2018-6To know more about intermittent fasting, get learning resources such as those listed below, and register today to be a Sports Nutrition Specialist (SNS®) on the GPNi® platform.You also learn about the GPNi®'s patented "traffic light system."Green – Good & Solid ResearchOrange – Some Limited Research but Not Considered HarmfulRed – No Solid Research and Maybe Some Health ConcernsThis enables you to learn what to safely recommend to your clients, athletes, and yourself.You can also choose one of our Continued Education Certificate programs, such as the Endurance & Marathon Nutrition Coach (EMNC®) certificate program.

Editorial By Cassie EvansEvery athlete, recreational and elite, is on the perpetual quest of improving. Whether it is increasing strength, a faster pace or building endurance, there is a never-ending list of strategies promising to enhance performance. Of course most of us are familiar with the basics; the importance of nutrition, training programs and recovery. Often overlooked is the importance of sleep. Sleep is needed for the body to repair and help individuals function at their best. Lack of quality sleep can decrease cognitive function, hinder performance and has serious implications for overall health. Chronic sleep deprivations increases blood pressure and increases risk of heart attacks. In terms of performance, lack of sleep is linked to decreases in sprint time, decreased reaction time and increased risk for illness or injury. Comparable to adding performance enhancing supplements to an athlete’s nutritional regimen, supplements are available to improve quality sleep. One such supplement is ZMA.ZMA, short for zinc magnesium aspartate, is a dietary supplement purported to improve quality of sleep, build muscle and boost recovery. Zinc is a trace mineral most commonly known for its role in immunity. Zinc even plays a role in muscle cell activation, proliferation and differentiation. Magnesium, another mineral, serves as a cofactor for enzymes involved in protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation. Magnesium also activates the para-sympathetic nervous system, which helps the body and muscles relax. Regular magnesium supplementation is linked to lower levels of stress and decreased levels of cortisol. Most ZMA supplements contain pyridoxine or vitamin B6. This vitamin plays a major role in metabolic pathways used during exercise such as gluconeogenesis and glycogenolysis.Only a handful of studies have examined the effects of ZMA in the athletic population. One study reported increases in testosterone and insulin like growth factor (IGF-1) after 7 weeks of  ZMA supplementation. However, another study did not observe any increases in testosterone and insulin like growth factor in resistance-trained men. There is research for both zinc and magnesium. One study reported improved time falling asleep and staying asleep after 8 weeks of daily supplementation of 500 mg of magnesium. Another study reported enhanced sleep after 7 weeks of zinc supplementation. Despite supporting evidence for each separate ingredients, the International Society of Sports Nutrition states there is little to no evidence to support efficacy of ZMA supplements.Is this the right supplement for you? ZMA supplementation could help an individual meet their daily micronutrient needs, especially if they are deficient or their diet is lacking. The research is still mixed in terms of being an effective supplement for athletic performance, recovery, and getting better quality sleep. It might be worth a try if you are having trouble with sleep as the evidence has linked magnesium to improved sleep. Good sleep definitely helps performance. The typical recommended dose for adults is 30mg of zinc and 450mg of magnesium aspartate. For best results, consume 30 minutes prior to bed and get ready to catch some zzzzzs. Editorial By Cassie Evans (MS, RD, CISSN)
