Not as uncommon a question as the more informed here might think! But, you too may have been asked that Q, and here’s a short vid to refer them to if/when they ask.
Levels of creatine, organic contaminants and heavy metals in creatine dietary supplements
Food Chemistry. Volume 126, Issue 3, 1 June 2011, Pages 1232–1238
High performance liquid chromatography (HPLC) has been optimised for the analysis of the creatine content and possible organic contaminants in 33 samples of creatine supplements from the market. Creatinine resulted to be the major organic contaminant (44% of the samples over 100 mg/kg). About 15% of the samples had dihydro-1,3,5-triazine concentrations exceeding the detection limit of 4.5 mg/kg (maximum 8.0 mg/kg) and a dicyandiamide concentration over 50 mg/kg, while none of the samples were contaminated with thiourea. The heavy metals (arsenic, cadmium, mercury and lead) content was also assessed by means of inductively coupled plasma mass spectrometry (ICP-MS). Only mercury was present in detectable amounts (at levels lower than 1 mg/kg).
• A survey on quality of creatine supplements commercialised in Italy has been carried out.
• Creatinine resulted to be the major organic contaminant (44% of the samples over 100 mg/kg).
• 50% of the products exceeded the maximum level recommended by EFSA for organic contaminants.
• Among heavy metals, only mercury was present in detectable amounts (<1 mg/kg)

How dieting makes the lean fatter: from a perspective

adipostats and proteinstats awaiting discovery

Whether dieting makes people fatter has been a subject of considerable controversy
over the past 30 years. More recent analysis of several prospective studies suggest,
however, that it is dieting to lose weight in people who are in the healthy normal
range of body weight, rather than in those who are overweight or obese, that most
strongly and consistently predict future weight gain. This paper analyses the ongoing
arguments in the debate about whether repeated dieting to lose weight in normal-
weight people represents unsuccessful attempts to counter genetic and familial
predispositions to obesity, a psychosocial reaction to the fear of fatness or that
dieting per seconfers risks for fatness and hence a contributing factor to the obesity
INTRO: I remember well when Jenny was a new member to the Fat Loss Revealed forums. She was in need of a serious revamp of her approach to nutrition and exercise to get the results she wanted. Like so many, she was confused and overwhelmed by all the conflicting and terrible information out there. What I didn’t know at the time was she had been dealing with eating disorders which obviously compounded her ability to get on the right track for her health, well-being and personal fitness goals. Regular writer for BrinkZone, long time member of both the Fat Loss Revealed and Body Building Revealed forums, trainer, and owner of shailafitness.com, Sumi Singh does a Q&A with Jenny on how she finally broke threw the barriers, which I think everyone will find inspiring, regardless of where you are in your personal health/fitness journey. Jenny shows that with the right info, hard work, commitment to change, it can be done; be it fat loss, improved health, etc.
Excerpt from “Overcoming Disordered Eating: A Personal Story”
Sumi: What was your first sign to yourself, that something wasn’t right?
Jenny: When you are so hungry and yet so afraid of people seeing you eat—for fear they’ll judge you— that you feel it necessary to sneak food and inhale it while hidden in a bathroom or closet…it’s a pretty strong indication something is not right.
Sumi: I understand you went through several phases; first anorexia, then bulimia. Or was it a mix of both?
Jenny: It was a mix over the years. I started by skipping meals and going long periods having only eaten a very small amount. That can really only be sustained short-term because people start noticing and the last thing I wanted was for someone to nag me about how I needed to eat moreAlso, you get really hungry eventually you binge because, well, you’re hungry. So that’s when the purging started because I realized I could eat and appease those people saying I needed to eat and the food didn’t really ‘count’ since it wouldn’t be staying down there for long. To me, that was balance—don’t eat around certain people, then eat and purge when you’re around others.I also exercised quite a bit; I grew up roller skating and I bought VHS tapes and did them at home. Cher’s first step aerobics VHS was my jam and I did it so much that I had it memorized (I could probably do it today with my eyes closed).
Sumi: When did you realize that you needed help? Who helped you? What steps did you take?
Jenny: This all continued on and off for around 9 years. I did go months at a time without purging, but disordered eating (skipping meals, hiding food, starving, and bingeing) was still very much a part of me for 9 years.Then I met the man that would later become my husband and he was accepting and loving and even though I thought I had hid my ED well (I had hid it from everyone else), he knew and he told me it wasn’t necessary and I believed him. I felt safe being me. I’m oversimplifying it, but really at that time, I thought that because he loved me, I could just be me and I’d be fine. I didn’t fear eating in front of him, so I ate. Unfortunately, I didn’t know how to eat properly; we were poor growing up, so all I knew was soda, fast food, spaghetti noodles with butter, comfort foods, etc. So what do you think happened? I got fat, that’s what happened. I basically swapped one extreme for the other.
It didn’t happen overnight, but little by little over the years I piled on the fat. I was overfat and feeling helpless—that was me. I could say that because I had stopped purging and I was now fat—which is what most consider to be the opposite of someone with an ED—that I was recovered from my ED, but I would be lying, right? Because overeating to the point of becoming overfat is still a form of disordered eating, isn’t it? Anyway, I didn’t want to go back to what I had done before, because I didn’t want to end up in the same place I started…
Meanwhile my husband was applying for a new career and we had started doing a lot of research about it and I ended up on some forums intended for those applying for this particular field. The application process required that you pass a physical agility test and there was this one guy on the forums that was super helpful to everyone and kept answering people’s questions on how to prepare for such a test.
That man was Will Brink. He was so knowledgeable on fat loss and fitness, so I started researching Will and found his Fat Loss Revealed e-book and forums. I bought his book in 2009 and I would say that’s when my real life-changing journey started.
I dove into the e-book and forums and started reading as much as possible, trying to learn how to lose fat and be healthy. At first it was like reading a foreign language, but I was determined and the moderators on the forum were so knowledgeable, helpful and patient…boy, were they patient. I asked anything and everything and if I didn’t understand, I would ask for clarification.
Got Back Pain?
Chronic back pain is at epidemic proportions that costs $100 billion annually in the US alone. That’s billion with a capital B folks! One of my favorite general public articles on the topic was in News Week and was titled “The Great Back Debate.”
In many respects, it was a most ground breaking article. Why? Because it was major “mainstream” publication that attempted to examine truly non-traditional causes of back pain. It made a serous attempt to look at non-physical causes of back pain and non-invasive treatments. Causes that would have been relegated to “non-scientific” status just a few years before that, were being taken seriously by a normally conservative publication. I consider it a must read article for anyone with chronic back pain.
In particular, the article explored the psychological basis for back pain, and did so commendably. Since that article, several reviews on the topic have come out, and continued to support the general conclusions from the News Week article. Some key comments in the article for example:
“The answer, Carragee and others believe, has as much to do with the mind as it does with the body. In the HIZ study, the best predictor of pain was not how bad the defect looked but the patient’s psychological distress. Depression and anxiety have long been linked to pain; a recent Canadian study found that people who suffer from severe depression are four times more likely to develop intense or disabling neck or low-back pain. At the Integrative Care Center of New York’s Hospital for Special Surgery, physiatrist Gregory Lutz says he routinely sees men who have two things in common: rip-roaring sciatica and an upcoming wedding date. The problem in their back, possibly a degenerated or herniated disc, probably already existed, says Lutz, but was intensified by the ole premarriage jitters.”
Every culture has its myths and bodybuilding is no exception. Like most myths, most are nine parts fantasy and one part truth, though of course, some myths have no truth to them at all. I have spent much of my career attempting to expose myths surrounding bodybuilding and topics that relate to it, such as drugs, nutrition and supplementation etc.

Meal frequency and timing in health and disease
Although major research efforts have focused on how specific components of foodstuffs affect health, relatively little is known about a more fundamental aspect of diet, the frequency and circadian timing of meals, and potential benefits of intermittent periods with no or very low energy intakes. The most common eating pattern in modern societies, three meals plus snacks every day, is abnormal from an evolutionary perspective. Emerging findings from studies of animal models and human subjects suggest that intermittent energy restriction periods of as little as 16 h can improve health indicators and counteract disease processes. The mechanisms involve a metabolic shift to fat metabolism and ketone production, and stimulation of adaptive cellular stress responses that prevent and repair molecular damage. As data on the optimal frequency and timing of meals crystalizes, it will be critical to develop strategies to incorporate those eating patterns into health care policy and practice, and the lifestyles of the population.
