HCG Challenge – Show us the quality evidence!

This is where the discussion on the validity and usefulness of the hormone HCG for weight loss will take place (the YouTube post area limitations make it very hard to make clear and thorough points). Our position is there is no quality evidence that the use of HCG increases fat loss, or helps maintain muscle tissue, or has any other physical or psychological benefits besides a placebo affect. This position is based on the number of studies that have been done on HCG. Although a number of studies may not be perfect, the weight of the evidence that is currently available supports our position on HCG. Therefore, we do not feel it is a useful tool for weight loss. A more complete discussion is in our HCG Report.

Our challenge, to anyone, is the following: “Show us the quality evidence that HCG works and how it works and we will change our position on the use of HCG for weight loss” For any practitioner that recommends this hormone, you should have this type of information at the tip of your fingers.

Protein Intake for Muscle Maintenance for Weight Loss

“Increased Protein Intake Reduces Lean Body Mass Loss during Weight Loss in Athletes”

This is a short-term study on the effects of increased protein intake when dieting on lean athletes. First, let me say that, as always, this is only one study. Recommendations and practice should be based off a body of evidence.

Here’s what you need to know:

Two groups dieted with calories at 60% of weight maintenance for two weeks. One group ate 35% (about 2.3 grams of protein per kg of bodyweight) of their calories from protein, while the other group at 15% (about 1 g of protein per kg of bodyweight) of their calories from protein. We’ll call them the PRO group and Control group, respectively. Here are the body mass stats (simplified):

PRO – Total Mass Lost – 1.5kg, Lean Mass Lost – .3kg, Fat Mass Lost – 1.2kg

Control – Total Mass Lost – 3kg, Lean Mass Lost – .1.6kg, Fat Mass Lost – 1.4kg

So, as you can see the PRO group lost roughly the same amount of fat mass but much less lean mass. That’s a good thing, especially in this population. Think about a wrestler who needs to make weight but obviously needs muscle to perform. This type of research has been performed in obese/overweight populations with similar results.

Notice that the PRO group’s intake is about 2.3 grams of protein per kg of bodyweight. In S.P.E.E.D., we recommend 1.5 kg in S.P.E.E.D. and other researchers advise that up to 2.5g PRO/kg is acceptable without any risk. (Layman)

S.P.E.E.D.

I could go deeper into this study, and I will if you all want me to. If so, leave a comment and I’ll post an update later. Remember, each study needs to be read with a large amount of skepticism and scrutiny. We’ve used over 250 references in S.P.E.E.D., many of them are studies like this one. Now think about all the studies we read that didn’t get used in the book. We’ve done our homework to make it easier on you. I would honestly like to charge hundreds of dollars for our book because I know that’s what it’s worth. But, the market says $19.95 so that’s what it’ll cost you.

Remember, let me know if you’d like more info about this study!

Fast Food Restaurants: Unjustly singled out as the primary cause of the weight crisis in the U.S.

It is a common belief that the increase in the availability and frequency of eating at fast food restaurants is a major cause of the current bodyweight and health crisis that is occurring in the U.S. For instance, Schlosser states “…it seems that wherever America’s fast food chains go, waistlines start expanding” (p.242) and a recent article by Craig Morgan in a local paper, which spurred me to write this article, stated “Fast foods’ [from fast food restaurants] ill effects on kids are well documented and real” (p.30). I will concede that fast food restaurants do have a number of items that can have a negative affect on health if eaten often. But, they do have a number of items that can fit into a fairly healthy diet and can actually be included in a weight loss diet. For a good rebuttal to Morgan Sperlock’s Super Size Me you should watch the documentary Fat Head by Tom Naughton.  There is much more that could be said on these topics but that is outside the premise of this article. The premise of this article is that Fast Food Restaurants, such as McDonalds, Taco Bell, and others should not be singled out as the major players in the weight and health crises.

It is really the whole processed food industry that needs to be discussed if any “blame” is to be given out. You can get plenty of high sugar, processed “crap” in the grocery store, convenience store, movie theaters, and most any place that food is sold! Not to mention that it is likely that a person will eat MORE food when eating at family type restaurants than at a fast food restaurant. (Brownell, p.37)  Even then there is still the case to be made for personal responsibility. Nobody is making you drink a 32 oz soda (has about 100 grams of sugar) or eat 4 donuts with a coffee that is loaded with sugar and so on. When it comes to kids, parents have a lot of control of what the kids will eat. The problem is that many parents eat poorly; therefore, they are setting a poor example and passing on these habits to their kids. How does a 5 year old purchase a sugar filled soda, or a tub of ice cream, or a jumbo bag of chips or a super size fry? There is no doubt that a lot of marketing and advertising practices are specifically aimed at modify eating behavior. It is clear that a majority of these ads are for products that are not very good for us, particularly in volume. Anyway, there are many reasons, (biological, psychological and social aspects as well as conflicting recommendations from experts and so forth), why people eat what they do and why they eat the amount they do.

Back to the discussion of whether Fast Food restaurants, specifically, are causing the weight problems. The evidence for this view is rather weak. Dr. Glassner, in The Gospel of Food, does a good job of discussing the validity of this issue as well as other hot topics related to food and health (Glassner, 2007). With respect to bodyweight, he states “only a small number of studies have attempted to test the fast-food hypothesis directly, and they have come up with mixed results” (Glassner, p.183). He discusses the details of a number of these papers. I too read these papers and found that the view that eating at fast food restaurants causes weight problems in a lot of people is not very convincing. For example, a 2001 paper in the International Journal of Obesity stated “Overweight status was not significantly associated with FFFRU [frequency of fast food restaurant use] among males and female. Interestingly, BMI was significantly lower among males who reported using fast food restaurants three or more times per week, compared to those reporting less frequent fast food restaurant use” (French et al, p.1828). Another paper on the subject states “…cross-sectional studies did not find any association between fast food restaurant use and bodyweight or body mass (BMI, in kg/m2) in children” (St-Onge et al, p.1069). This final quote, from the St.Onge et al paper, should be considered when trying to  pin the blame on fast food restaurants:

Although longitudinal data are not available concerning increased fast food consumption and body weight changes, one can propose that increases in body weight and increases in fast food and snack consumption are concurrent events that potentially are causally related. However, any reference to causal relations should be made with extreme caution, given that no data are currently available to show such a relation (St-Onge et al, p.1069, emphasis added).

However, the situation is certainly not a bed of roses. For instance, one of the papers previously mentioned stated “fast food restaurant use was associated with greater intakes of soft drinks and lower intakes of fruit, vegetables, grains, and milk” (St-Onge et al, p.1069). Another paper had a similar conclusion “FFFRU is of concern because of its association with lower calcium intake and higher soft drink [non-diet] consumption” (French et al, p.1831). It is more likely that the increase in soft drink consumption, which is available everywhere, is playing a more significant role in the weight and health problems than does the eating at fast food restaurants (St-Onge et al; Bray et al; DiMeglio et al). So it is clear that eating at these types of establishments can negatively affect the quality of the diet. This would certainly not be beneficial for overall well-being. Again, poor eating habits occurs everywhere and poor quality foods, such as soda and deep-fried anything, are available everywhere.

It does seem clear that singling out fast food restaurants as a major cause of our current weight and health problems is not well supported and is a very big oversimplification of the problem. There are some good and bad aspects to this particular vehicle of food delivery. There are ways to dine at these facilities so that is fairly healthy. In fact, as Tom Naugton displayed in his documentary, you can actually lose weight while eating at these types of establishments daily. I will end with a fitting quote from Dr. Glassner “I come neither to praise fast food nor to bury it, only to question its easy portrayal as the root of all evil” (p.146). To make a truly educated decision, I would encourage everyone to start out by reading The Gospel of Food, Fast Food Nation, The Omnivores Dilemma, and watch Tom Naugton’s funny and informative documentary Fat Head.

Kudos to WebMD on the Acai Berry

I stumbled upon an article on WebMD this morning that discusses whether or not the acai berry is the weight loss miracle some promoters are claiming it to be. I was happy to find a well-written, to-the-point summary of why it’s irrational to think that acai berry or any other super-food is the key to weight loss.

A few weeks ago, Brad Pilon from Eat Stop Eat pointed out in his newsletter that a well-promoted (read:they’ve got ads everywhere!) acai berry weight loss product had “borrowed” before and after pictures from Brad’s website. To make things worse, they were pictures of Brad himself.

We recommend very few supplements in S.P.E.E.D. In fact, we don’t really recommend them, we just tell you which supplements have some good scientific evidence backing them up. If you want to use them, great. If not, okay too.

There’s something in the word supplements that should clue us in to how they should be used. They are a supplement to an already effective weight loss plan or program. It’s our constant thirst for the magic bullet that allows these types of sham products to exist and we need to change our attitude toward weight loss. Losing weight takes hard work, dedication, and a good plan. Now get to it.

Alternate Day Fasting Succussful for Weight Loss and Heart Health

Research Review:

A study in the American Journal of Clinical Nutrition shows some support for the ability of modified alternate day fasting (ADF) to facilitate weight loss and modify markers of heart health.

Subjects ate 25% of energy needs on fast days and ate ad libitum (at will) on alternate days. On fast days, subjects were instructed to consume all calories between noon and 2 p.m.  This pattern continued throughout the study. Subjects were also able to meet with a Registered Dietician (RD) (explains the horrible food choices they were provided on fasting days during the first 4-week period – chicken alfredo? really?) once per week.

The cool thing about the study’s design is that for 4 weeks, the subjects were provided a meal for each fast day, and for another 4 weeks were left to complete the program without prepared food. Adherence rates remained high for subjects who completed the study, which means ADF may be a valuable tool for weight loss and health in the real-world. One drawback was that 2 people withdrew from the study due to their inability to comply with the protocol – that’s 10% of the original subject pool. I guess ADF isn’t for everyone, although that’s not surprising.

Average weight loss over 10 wks (8 wks on weight loss diet – 2 on control diet) was about 5.8% or 5.6kg (12.3 lbs). Also decreasing were BMI, body fat percentage, total and LDL cholesterol, and triaglycerol levels. Systolic, but not diastolic, blood pressure was also lowered.

This study gives us a little more evidence that ADF or intermittent fasting (IF) might be a great tool for weight loss and health interventions. However, there are some drawbacks to this study. 20 subjects is a rather small sample size, so more studies with larger samples are a must.  The fact that subjects had weekly meetings with a coach (RD) most likely affected the adherence in a positive way. It would be interesting to see a study that compared an ADF plan with coaching to one without.

On a side note, the lead researcher Dr. Krista Varady commented on the subjects eating less than expected on ad libitum days and said “”I think it’s probably because their stomachs kind of shrunk.” Let’s get this straight. Stomachs don’t shrink. Feelings of satiety (fullness) change, but the physical size of the stomach does not shrink. Ugh… I can’t believe she said that.

What’s the deal with hot dogs?

When eating a low-carb diet it is useful to find quality protein sources that are quick and convenient, not to mention good for you. Surprisingly, there are certain types of hot dogs that qualify. You must be thinking “You must be kidding, hot dogs!?” Please read-on.

There is no doubt that the hot dogs are a ubiquitous food in the U.S. and so is the thought that eating hot dogs is unhealthy. However, it is not that simple and there are a number of misconceptions about hot dogs. Just in case you are wondering, we are not being paid by the national Hot Dog and Sausage Council (yes this is a real organization, see http://www.hot-dog.org/) to write this. There are typically three arguments used to support the idea that hot dogs are disgusting and unhealthy. These three arguments relates to; the quality of the meats used to make them, the amount of fat in them, and the preservatives, sodium nitrites or sodium nitrates, used in them.

Let’s first look at what hot dogs are made of. The following is a good overview of what hot dogs are made of, which is from http://www.sixwise.com/newsletters/06/10/11/what-is-really-in-a-hot-dog-and-how-unhealthy-are-they.htm

On to the million-dollar question: what are hot dogs made of? According to the National Hot Dog and Sausage Council:

“All hot dogs are cured and cooked sausages that consist of mainly pork, beef, chicken and turkey or a combination of meat and poultry. Meats used in hot dogs come from the muscle of the animal and    looks much like what you buy in the grocer’s case. Other ingredients include water, curing agents and spices, such as garlic, salt, sugar, ground mustard, nutmeg, coriander and white pepper.”

However, there are a couple of caveats. “Variety meats,” which include things like liver, kidneys and hearts, may be used in processed meats like hot dogs, but the U.S. Department of Agriculture requires that they be disclosed on the ingredient label as “with variety meats” or “with meat by-products.”

Further, watch out for statements like “made with mechanically separated meats (MSM).” Mechanically separated meat is “a paste-like and batter-like meat product produced by forcing bones, with attached edible meat, under high pressure through a sieve or similar device to separate the bone from the edible meat tissue,” according to the U.S. Food Safety and Inspection Service (FSIS).

Although the FSIS maintains that MSM are safe to eat, mechanically separated beef is no longer allowed in hot dogs or other processed meats (as of 2004) because of fears of mad cow disease. Hot dogs can contain no more than 20 percent mechanically separated pork, and any amount of mechanically separated chicken or turkey.

So if you’re looking for the purest franks, pick those that are labeled “all beef,” “all pork,” or “all chicken, turkey, etc.” Franks labeled in this way must be made with meat from a single species and do not include byproducts (but check the label anyway, just to be sure. Turkey and chicken franks, for instance, can include turkey or chicken meat and turkey or chicken skin and fat in proportion to a turkey or chicken carcass).

As you will see from the few brands highlighted below there is no problem with the quality of meats used. In fact, the organic grass-fed beef hot dogs are a very high quality meat which is better than any “regular” cut of meat you will get in almost any grocery store. Therefore, if you stick to the brands that use “all beef”, or “all chicken”, and particularly the organic or natural meats, there should be no concern with what the hot dogs are made from.

The second issue is the fat content of hot dogs. This really stems from the common, but misplaced fear about fats, particularly animal fats. There are many aspects of this issue but are beyond the scope of this article. For now, realize that a low-carb diet will be a higher fat diet, from both plants (avocados, walnuts, coconuts, etc.) and animals (beef, eggs, salmon, etc). Therefore, eating foods with fat in them is fine. The amount of fat in a particular hot dog will vary so you will need to read the nutrition facts label to know how much is in a specific one and how many you can eat to stay within your goal intake. Additionally, the grass-fed hot dogs will contain a good amount of omega-3 fats and CLA, which both have health and weight loss properties.

The third concern is the preservatives sodium nitrite or nitrates. These can lead to the formation of nitrosamines which are carcinogens (can produce cancer). These have been linked to cancers in the digestive tract. However, recent evidence for this connection has shown that typical intakes of these preservatives are not likely to lead to an increase in cancers (Powlson et al). Additional recent research is finding that food sources of nitrates and nitrites, particularly from vegetables, may be health promoting (Hord et al). There is more about this topic and, in fact, there have been a number of recent papers published on this topic so I will discuss this in greater detail at another time. For now, however, this topic is really not applicable if you eat hot dogs that are not preserved with sodium nitrite/nitrates. All of the following hot dog manufacturers listed below do not use this preservative. Therefore, these hot dogs do not contain nitrites or nitrates and the concern about ingesting cancer causing agents, which is not definitive anyway, is not a valid reason avoid eating this product.

Here are a few examples of healthy hot dogs; hopefully you no longer think that statement is an oxymoron.

Applegate Farms – The great orgahot dog applegatenic uncured hot dog

No nitrates or nitrites.

Made from 100% organic grass-fed and finished beef, these lean hot dogs are bursting with old-fashioned classic hot dog flavor—juicy, flavorful and delicious! These dogs have only 8 grams of fat compared to the average 15 grams in most brands, and because they’re made from grass-fed beef, they’re also high in omega-3 fatty acids (the good fat). Great on the grill or steamed on your stovetop any time you’re craving a taste of summer.

Ingredients:Organic Grass-Fed Beef, Water, Contains Less Than 2% Of The Following: Sea Salt, Organic Spices, Organic Garlic Powder, Organic Paprika, Celery Powder, Organic Onion, Lactic Acid Starter Culture (Not From Milk).

Let’s be Frank – Uncured Beef Frank

frank hot dogsNo nitrates or nitrites.

Made from 100% Grass-fed Beef

These snappy dogs are loaded with flavor, not junk! Using premium cuts from cattle raised on pasture in California (naturally high in healthy Omega 3 fatty acids!) and organic spices, we’ve crafted a delicious dog that’s lower in fat, calories and sodium than conventional franks. No nitrites, nitrates, hormones, or antibiotics, ever

Ingredients:Grass-fed beef, water, sea salt, organic evaporated cane juice, organic spice, organic garlic powder, natural flavor (celery powder, spice extract, paprika extract), spices, lactic acid starter culture, in a lamb casing.

Trader Joe’s – All Natural Uncured All Beef Hot Dogs

trader joes hot dogs

No nitrates or nitrites.

Ingredients: Beef, water, contains less than 2% of the following; allspice, celery juice powder, evaporated cane juice, garlic powder, ginger, honey, lactic acid starter culture, mustard, nutmeg, onion powder, paprika, pepper, sea salt.

In conclusion, the belief that all hot dogs are bad to eat is not supported by the evidence. If you eat a quality hot dog there seems to be no good reason that they cannot be part of a healthy diet, whether high-carb or low-carb. The benefit with a low-carb diet is that you can eat more of them! One way that Matt and I like them is lightly warmed-up with a bit of organic mustard and with a side of baby carrots or a small apple; how easy is that!
