The FullBar Diet Has It Half Right

by Janet on August 10, 2009

fullbarThe latest diet product starring in late-night infomercials, buzzing on the Internet, and showing up in health food stores (even Walgreens) is FullBar.  If you’re not planning to have weight loss surgery any time soon, these appetite-curbing bars are the next best thing — or so claims the creator Michael A. Snyder, MD, a bariatric surgeon in Denver.  You can learn more about these products and how you can “Be Full, Live Full” by visiting the FullBar web site. Or check out a review of the FullBar Diet Plan by registered dietitian Kathleen Zelman on WebMD.

By eating these granola-type bars twice a day with an 8-ounce glass of water 30 minutes before your meals, Dr. Snyder says you can achieve the same weight-loss results without the surgery.  How convenient! He claims to have the “real secret” to losing weight:

“When you feel full, you eat less.  When you eat less, you lose weight.”

Yeah, right.  Got that.

He also promises…

“No special diet. No calorie counting. No hassles.  It’s worked for a lot of people.”

Certainly one person it didn’t work for is Roni.  I especially enjoyed her rant against FullBar.  Maybe I’m just glad not to be the only one ranting.

Sure, I can appreciate the importance of managing hunger.  And it’s true that feeling full on fewer calories is an effective weight management strategy.  That’s the foundation of one of my favorite approaches to weight control:  The Volumetrics Eating Plan by Barbara Rolls.   Dr. Rolls is one of the country’s leading authorities on satiety and her hugely popular books show people how they can choose foods that control hunger while losing weight.

I give him credit, Dr. Snyder has hit on a nutrition hot button.  Satiety does appear to be the new weapon in the war on weight — and lots of  other new products on supermarket shelves are toutingaquafull_berry_bliss_4002 their ability to control hunger, including Dannon Light & Fit Crave Yogurt, Lightfull Foods Satiety Smoothie and Aquafina Alive Satisfy.  Many of these foods and beverages are fortified with so-called functional fibers, such as maltodextrin or inulin (an extract typically from chicory root or Jerusalem artichoke).  Inulin is the key ingredient in the “liquid form” of FullBar called AquaFull. These flavored artificially-sweetened powdered drink mixes are to be added to water and consumed along with your twice-a-day FullBar before mealtime.

These products are not meant to be meal-replacements, but simply pre-meal supplements to help you eat less during your meal. Of course, you’ll need to really pay attention to your internal hunger cues during your meal and stop eating when you’re satisfied (which is easier said than done).  Otherwise, you’ll be adding up to 360 additional calories by eating two FullBars each day.

But my biggest concern is the product itself.  I think the best approach is to eat real food to curb your appetite — the techniques that Dr. Rolls suggests in Volumetrics.  Foods with a lot of “volume” and not a lot of calories include water-laden fruits and vegetables.  Other belly-filling foods include soup.  Studies that Rolls and colleagues conducted at Penn State have shown that eating a bowl of  broth-based soup before your meal helps you to eat less and reduce overall calories.  For 180 calories, I can sure think of a lot more nourishing, satisfying and appealing options than a FullBar to take the edge off your appetite.

The first two ingredients in the bars are brown rice syrup and puffed wheat cereal.  Even though the web site says “no processed sugar,” the bars are loaded with sweeteners — including high fructose corn syrup, agave nectar and honey.  Agave nectar and honey may have a “natural” halo, but there’s no significant difference between these sweeteners and high fructose corn syrup or sucrose.  Get your facts straight, Dr. Snyder, these sweeteners ARE sugar.

The bars come in five different flavors:  Cocoa Chip, Caramel Apple Crisp, Cranberry Almond, Peanut Butter Crunch and Fresh Berry Bliss. They’ll cost you $175 for a 2-month supply (although you’ll get the third month free). Those are the online costs, retail prices may be higher. Perhaps one of the comments I most objected to on the web site was how you can actually SAVE MONEY with FullBar because of all the real food you won’t need to buy.  Ugh.

Dr. Snyder is even promoting these products to kids, as you can see in this video below. He describes the “all natural” FullBar as a healthy snack for kids.  Not in my book.  Instead of a Caramel Apple Crisp bar, what about an apple?  These snacks are high in sugar and contain very few nutrients: 0 vitamin C, 0 vitamin A, 4-6% DV calcium. Since these bars aren’t intended to be meal replacements, they contain a lot fewer nutrients than other nutrition bars.

Managing hunger may be important to help stay on track if you’re trying to lose weight, but I don’t think these products are the answer.

Diet Myths That Keep Us Fat

by Janet on May 7, 2009

I haven’t read this book yet, but I like the title.  Darn, it’s the book I wish I diet-myths-that-keep-us-fat1would have written.  But there are lots of other myths out there to tackle!    It looks like from Dr. Nancy Snyderman’s appearance on Today that she focuses on debunking these myths…

Myth 1:  Your weight is your fault
Myth 2:  Your body shape doesn’t matter
Myth 3:  Calories don’t count
Myth 4:  Carbs are bad for you
Myth 5:  Carbs are good for you
Myth 6:  Diet drugs are a magic bullet
Myth 7:  Dieting is all you need to lose weight
Myth 8:  Supplements will make you thin and happy

I liked a lot of the things she had to say…

  • Many of us have been fed bad information about diet, nutrition and weight loss.  Bad information means bad choices, and bad choices mean bad results — or no results.  You can’t get in shape and stay healthy unless you know the truth.
  • Make informed decisions using sound, straightforward information.  Question whether a popular diet will really work for you.
  • Learn to make a friend of food and exercise.  This will allow you to safely sprinkle the not-so-healthy stuff through your diet and not feel deprived.
  • Escape the forbidden-food mentality, allow yourself some leeway and learn to enjoy food again.
  • It’s not about becoming supermodel thin or adhering to someone else’s ideal — it’s about being healthy and feeling great.  And it’s never too late to begin the journey.

I couldn’t have said it better myself.

Ch-Ch-Ch-Chia! Gag Gift or Miracle Food?

by Janet on April 27, 2009

When you hear the word chia you may think of those laughable terra-cotta figurines that sprout green “hair” when watered.  The original Chia Pet was introduced in 1982 by Joseph Enterprises  – the same company that markets the infomercial classic “clap on, clap off”  Clapper.  The latest Chia is a controversial head of obama_chiaPresident Obama, which was pulled from Walgreen’s after the company found the item “objectionable.” 

Now chia seeds have been appointed the latest super food —  something I find a bit objectionable.

Sure, chia seeds are OK.  There’s nothing wrong with them, but they are not deserving of the “miracle” status and the excessive hype that’s been hard to escape on the Internet lately.

Chia seeds come from the desert plant Salvia hispanica, a member of the mint family that grows abundantly in Mexico.  These nutty seeds were highly prized by the Aztecs in pre-Columbian times and are still widely used in Mexico and South America — often ground to create a meal called pinole for porridge or cakes, or soaked in water or juice to make a drink known as chia fresca.

One of chia’s biggest claims to fame is the omega-3 content, which is indeed higher than what you’ll find in flaxseed.  But it’s important to remember that both chia and flax contain omega-3 ALA (alpha-linolenic acid), which your body needs to convert to the more powerful DHA and EPA forms of omega-3 that are found in fish oils and algae extract. The amount that’s actually converted is quite low, and it’s not clear if ALA protects the heart and the brain like the omega-3 in fish.

Chia seeds are relatively high in a type of soluble fiber that’s quite viscous.  In fact, mix the seeds with water and it will form a gel.  That means the seeds are slowly digested, which may be beneficial to help manage blood sugar and control appetite.  But this doesn’t translate into a “miracle food for diabetics” or a “dieter’s dream.”

buy-chia-seeds3Go ahead and enjoy chia seeds if you like them, but don’t let them distract you from eating more fish — or focusing on eating a variety of  fruits, vegetables and whole grains.  It’s the overall combination of foods that really counts.  Chia seeds, like flaxseeds and other seeds (as well as nuts), can be a beneficial part of a healthy diet, but they’re not going to transform it.   The amounts people typically eat are quite small — not sufficient quantities to deliver the levels of nutrients touted in the online ads.

If you want to try chia seeds, some people like to sprinkle these black or white seeds on cereal, yogurt or salads and bake into breads, meat loaves or casseroles.  Many recipes with chia, including those found in the Miracle of Chia, involve soaking the chia seeds in water to form a gel.  But Wayne Coates, a retired professor at the University of Arizona and co-author of Chia: Rediscovering a Forgotten Crop of the Aztecs, says that’s not necessary.  He said it’s a myth that you need to soak the seeds to bring out the soluble fiber.  You also don’t need to grind chia seeds like flaxseeds.  Chia seeds do not have the same hard seed coat so you can skip this step.

Whatever you do, just don’t eat the sprouting “hair” from a Chia Pet.  These sprouted seeds have not been approved for consumption — only amusement.  My vote for the best ancient Aztec food is quinoa.

The Sly Allure of ‘Super Juices’

by Janet on February 23, 2009

There’s a powerful movement sweeping the country (actually the world!) and if you’re not careful, you might fall victim to the allure of the super juice.   If you’re not drawn in by the purported curative powers – cancer, diabetes, heart disease, Alzheimer’s, immunity, depression, drug addiction – then you might be tempted by the potential to make some extra cash.

mona-vie-product-picsThese so-called super juices, including MonaVie, Vemma and XanGo which contain acai, goji, mangosteen and other exotic fruits, are at the center of multilevel marketing or “pyramid” schemes that rely on aggressive sales pitches by the converted.  Trouble is, the enthusiastic, well-intentioned distributors who sell these “liquid antioxidants” out of their homes or on the internet have been drinking the proverbial Kool-aid. These expensive juices –  $40 to $80 per bottle — do not live up to the hype. Studies have shown that eating an apple will give you more antioxidants. An independent investigation by the Associated Press found XanGo’s antioxidant strength is no better than other fruit juices that are readily available in supermarkets for a fraction of the cost.  

xango2An analysis by Men’s Journal found that MonaVie tested extremely low in  phytonutrients (anthocyanins and phenolics).  In fact, it contained even fewer of these beneficial compounds compared to apple juice, which also tested poorly.  Grape juice had five times more vitamin C.

vemma1Word of mouth is a powerful marketing tool, but testimonials are not reliable evidence.  I always think it’s a red flag to take nutrition advice from someone without any credentials beyond their status in a marketing company (along with a big financial interest in the advice).   The National Council Against Health Fraud and Dr. Stephen Barrett of Quackwatch have issued several warnings related to multilevel marketing of health products.  Even some former distributors of MonaVie feel burned by the experience and are warning others in the blog Purple Horror.  

An Australia consumer watch-dog group called Choice  investigated the claims made by nine popular super juices and found that the antioxidant content was not as high as “their marketing hype had led us to expect.”  In many cases, eating an apple would provide you with more.

“You get a novelty fruit, call it a super fruit, throw in a secret Himalayan mountain or Chinese valley with mist on it, or a Pacific island with traditional healers who live to 150, and it’s a very potent brew.  Then if it costs a lot, people assume it must be rare and very good for you,” said Choices spokesman Christopher Zinn.

One of the earliest super juices was Juice Plus, and it has had several legal challenges and critics, including Dr. Stephen Barrett of Quackwatch. 

Now more than ever – when budgets are stretched – we do not need the distraction of super juices, which can set you back more than $100 a week if you follow the twice daily regimen.  Besides the high price, you’ll be adding a lot of extra calories for nutrients that you’d be better off getting by eating a VARIETY of fruits and vegetables every day.  Besides, dietary guidelines suggest “go easy on fruit juices,” which should be limited to just 1 cup a day.  As far as the vitamins and minerals in these super juices, you can simply take a much cheaper multivitamin and save the rest of your money for groceries.
