There are a number of reasons for which you might undergo open-heart surgery. Coronary artery bypass grafting surgery is quite common and is indicated for coronary artery disease (blocked arteries) either after a heart attack or to prevent a heart attack. Mitral and/or aortic valve repair or replacement are also common and may stem from a childhood case of rheumatic fever [...]
The Ab Wave is 2012′s addition to a long line of questionable infomercial exercise gimmicks with little redeeming value. Unlike other ab gadgets, this one takes lazy to a whole new level. You actually sit in the machine and then swing side to side [...]
You trudge away on the treadmill and scrape by on seeds and sprouts, but the bathroom scale won’t budge. Self-proclaimed health “gurus” and hokey fitness gimmick infomercial hosts promise you can cull the kilos (or pare away the pounds) [...]
My original Ab Circle Pro review went viral across the fitness industry. I received countless emails from health professionals praising me for taking the time to stand up against such abject nonsense which, to the trained eye, appears to be nothing more than a useless gimmick meant to turn a buck off unsuspecting consumers. Unfortunately, the article was extremely long so by popular demand I have crafted a point by point short version [...]
There is very limited scientific research surrounding the impact of exercise training on thyroid function and specific exercise guidelines have yet to be established. Dr. Bill Sukala sifts through the science to provide sensible and prudent exercise guidelines for thyroid disorders hypothyroidism and hyperthyroidism.
Protein is a nutrition rock star. It has a great marketing machine behind it, but just how much protein do you really need? Television morning show hosts and robotic news anchors promote protein with reckless abandon and little concern for the [...]
The popularity of herbal supplements is soaring. With the public’s growing distrust of the medical establishment, people are shying away from prescription and over the counter weight loss drugs, instead opting for the “natural, help yourself” approach. However, tip-toeing through a virtual herbal minefield can be confusing, if not downright intimidating without an earned doctorate in botany.
Do High Protein Diets Work For Weight Loss? The bottom line is yes, high protein diets DO cause weight loss. HOWEVER, the caveat is that the associated weight loss is not all fat, particularly on diets which induce quick initial weight loss. While I’m quick to offer a pat on the back to anyone who’s lost weight, I often caution against [...]
Would you buy a diet book written by a medical doctor? Legions of self-styled health gurus with just enough nutrition knowledge to be dangerous love having a dig at doctors who “know nothing about diet because they get less than 25 hours [...]
The self-proclaimed weight loss “experts” are at it again touting the latest fashionable supplement du jour. Raspberry ketones (RK) derived – not so surprisingly – from raspberries purportedly help you lose that extra fat once and for all. Suppliers can’t keep up with the demand since television health evangelist Dr. Oz and supplement-spruiking sid-kick Lisa Lynn [...]
Belviq may help some individuals, but it is not a magic bullet. Consumers should be well-aware that there may be future risks which are not yet evident. The best available evidence still holds that lifestyle changes which include nutrient-rich foods [...]
I was recently approached by a company with a financial interest in the sale of the herbal slimming pill caralluma fimbriata. Their aim was to line up a PhD-level academic to go on a prime-time TV program [...]
No other single nutrient has been more misrepresented and maligned than carbohydrate. Sugar, as it’s commonly known, has been singularly scapegoated as the culprit behind our expanding waistlines, chronic diseases, and child hyperactivity disorders – among others. The mass media, ever thirsty for sensationalized headlines [...]
Zaggora Hotpants™ are the latest in a long line of slimming garments which purportedly “reduce the appearance of cellulite” and trim inches off your hips and thighs, with the effect further enhanced by wearing them during exercise. This sounds impressive, but is there any merit to these claims?
There is a lot of confusion out there about the role of exercise in managing weight and body fat. Ask researchers working in the area of obesity and weight control and they’ll tell you that most of the research shows that exercise alone does little to a person’s weight, and only modestly changes how much of that weight is fat and how much is everything else. Being a scientist, I’ve looked at the studies and I’d have to at least partly agree….
People tell me how great their workouts were going, how much weight (fat) they were losing, but then a brick wall in the form of a weight loss plateau. But what IS a weight loss plateau, what causes it, and how do you overcome it and get back on track towards your health and fitness goals?
It’s a common question, but what exactly is metabolism? Simply put, it’s your internal calorie-burning firepit – the amount of energy your body burns to sustain itself. This includes your resting metabolic rate and additional calories (or kJ) expended from physical activity and digestion. Your metabolism is influenced by a number of factors…
Most people these days have heard of body mass index (BMI), but might be a little bit confused on how to calculate it. But before we get too far ahead of ourselves, what is BMI and what do the numbers tell us?
When you’re trying to lose weight, it’s easy to obsess over the numbers on the bathroom scales as you measure your progress. But fear not, daily weight fluctuations are nothing to worry about and I guarantee you have not put on more fat overnight. Small daily variations in scale weight are completely normal. For example, […]
Question: I do 40 minutes of cardio five times per week but can’t seem to lose weight. What else can I do? Answer: Even if you exercise regularly, your hard work can be “undone” by excessive sitting the rest of the day (i.e., desk job, watching television). Based on the Ainsworth Compendium of Physical Activities, […]
…but as I sat back and pondered the bigger picture, it’s that these Biggest Loser trainers attain worldwide fame and then seemingly toss their ethics out the door to hawk dietary supplements using flimsy or misleading marketing. They overlook obvious gaping holes in the product’s scientific merit big enough for their cash cow to do a somersault through it. I think if Bob Harper or any of the other trainers out there were worth their professional salt….
Calorad collagen dietary supplements stormed onto the scene around the mid to late 1990s with claims that you can “lose weight while you sleep.” The marketing claims the product can improve a multitude of ills.
We’ve been hearing about it for years. Free radicals are molecular villains responsible for everything from aging to heart disease to cancer, and that’s not even the tip of the iceberg. Open up any fluffy health or fitness magazine at the supermarket check-out line and you’ll see glossy advertisements touting the “cure”: antioxidant supplements. Then you go home, turn on the television, and there’s the news reporter citing some prestigious university’s study about how antioxidant supplements actually CAUSE cancer. What’s going on here? Who’s right; who’s wrong? Well, it all depends on whom you ask and which studies you believe. And even then, it’s still a very tangled web.
L-carnitine is a nitrogen-containing, short-chain carboxylic acid – technically, it is not an amino acid. It is a water-soluble, vitamin-like compound that is readily synthesized in the body from lysine and methionine. Although carnitine is not an essential nutrient because it can be synthesized in the body [...]
Pyruvate: More hype than help? Pyruvate is a dietary supplement targeting both sedentary and active individuals. The most popular claims for pyruvate center about its purported ability to: 1) “significantly” increase fat and weight loss; 2) improve exercise endurance capacity; 3) effectively reduce cholesterol, and; 4) serve as a potent antioxidant. Even at this late […]
Sugar is well and truly on the media hit list. Everyone loves to hate sugar, but is it all just overblown hype and hysteria? Could sugar really be all that unhealthy and fattening for us? A careful review of common sugar myths shows that the hysteria may actually be more harmful than sugar itself! It […]
What’s all this talk about the HCG Diet these days? Does it work? Is it safe? I’ll get right down to it and I’m not going to exercise any diplomacy in my choice of words: I’m calling the HCG diet yet another gimmicky, too-good-to-be-true, quick-fix diet which will probably only leave you lighter in the wallet and less healthy in the long run. The preponderance of scientific evidence shows that it has no effect on fat loss beyond that which can be accomplished by just reducing calorie intake.
I had hoped the Ab Circle Pro would die a quick death after my exhaustive product review from June of last year (Ab Circle Pro Review: Fat Marketing Claims Thin on Truth). The article went viral across the global fitness industry and I received a tremendous number of supportive emails and not a single negative one. But much to my chagrin, Jennifer Nicole Lee is back with a rehashed version of the product not so creatively dubbed the Ab Circle Pro version 2.0. As far as I can tell [...]
Much like the Power Balance holographic bracelet, the iRenew bracelet is yet another too good to be true gimmick which promises more hype than help. A thorough review of the iRenew website reveals a litany of suggestive half-truths and invented pseudo-scientific technobabble. In this independent review, my aim is to systematically and categorically evaluate iRenew’s website marketing content.
You’ve decided you’re ready to “graduate” and take the plunge by purchasing a gym membership. Before you start tramping on treadmills, you may have to tip-toe through a veritable minefield of salespeople and contract fine print. But the process of nailing down a gym membership need not be so intimidating. Arming yourself with the following pointers can help tip the scales in your favor!
