I’m currently reading Trick And Treat – how ‘healthy eating’ is making us ill by Barry Groves. Barry Groves has taken a close look at many studies. Often, the abstracts on the medical journal articles do not agree with what the data presented in the article would indicate. Also, some recommendations have no basis in research. One of those recommendations is the Five a Day advice for fruits and vegetables. Studies have shown that two a week is sufficient to get maximum benefit. I like vegetables enough that I’ll keep eating them anyway. As for fruits, they contain fructose, the most harmful of sugars. Their value is questionable when the nutrition they contain can just as easily be gotten from vegetables. Fructose is the sugar that causes belly fat. Fructose is also the sugar most detrimental to the immune system, though the other simple sugars aren’t far behind. Another source I’ve seen said that fructose is metabolized in the liver the same way that alcohol is, and we know what alcohol can do to the liver. Table sugar and high fructose corn syrup are about half fructose, which makes them dangerous, too. Barry Groves’ site: http://www.second-opinions.co.uk

Critique of studies on which our “healthy diet” advice is based
I just read Dr. Mercola’s critique of the principal studies on which our “healthy diet” advice is based, The Cholesterol Myths that May be Harming Your Health. It would seem that there’s a lot of misleading information being promulgated.
To start with, Dr. Ancel Keys cherry-picked his cases for the Seven Countries Study back in 1953 when he told us that higher fat intake correlated to higher rates of coronary heart disease. Had he used data from all 22 countries that had data available, no correlation between dietary fats and coronary heart disease would have been found.
Analysis of the Framingham Study showed that lower blood cholesterol levels were associated with a lower cardiac risk. What they did not tell us was that the same study determined that the more cholesterol and saturated fat people ate, the lower their blood cholesterol levels. And yet we were told to lower our cholesterol and saturated fat intakes.
And finally, while the “MrFit” Study did show a marginal decrease in coronary heart disease for those who ate a low-saturated fat and low-cholesterol diet, there was an increased all-cause mortality rate for those who followed such a diet with an increase in deaths from cancer, brain hemorrhage, suicide, and violent death.
The HCG Diet
There’s a page that lists the articles and research on the HCG Diet published in medical journals. It’s here. The FDA does not endorse the diet. HCG is not approved for weight loss; however, doctors are permitted to use drugs approved for other purposes as they choose. The HCG Diet is very strict and unforgiving of cheats. It takes tremendous dedication to follow this diet. Supposedly, the reward is, if followed through the stabilization phase, that one’s metabolism is reestablished so that one does not gain the weight back.
Stretching and resistance band videos
I have been using a couple of videos lately. Perfect in Ten: Stretch – 10-minute workouts has five ten-minute stretching routines. I’m doing the leg stretch routines in an effort to avoid Achilles pain. I’ve been troubled by that in the past when I’ve walked for fitness. The other video is a resistance band routine on SparkPeople. This one is online.
Benefits of weighing every day
I’ve been weighing every day since October 10, 2006. I’ve learned quite a lot about how my body handles different types of food that way. For instance, I’ve learned that salt is no big deal for me. Carbohydrates will jack up my weight by as much as two pounds the next day. My weight goes up a little around that time of month, but it didn’t do that when I was on the Medifast diet. Antibiotics can also cause weight gain. The process of weighing every day has been very educational. Had I not done it, I would not have known my body so well, and I would not have known what my problem foods are.
Everyone is different, and you may have different results. If you decide to weigh every day, be objective about it and treat it like a science experiment. Be sure your charting also includes ways to check your week to week weight. Weight may fluctuate day to day, but if you’re on plan, you should see consistency in weight week to week, whether maintaining or losing. Tracking your food is also an important part of the process. Track your food well so that when the scale goes up, you can look at your intake to see what changed—not just the calories, but also the macronutrient mix and specific foods, since any of these can make a big difference. Then you’ll know, “If I do this, then that will happen.” This will help you to make conscious decisions about your eating as well. You can say to yourself, “I know that this will happen if I eat that food, so I think I’ll avoid it.” or “I’m willing to take the hit.” Soon, you won’t be surprised, either, and you’ll also know what to do to correct problems. Using the objective scientific mind helps minimize the emotional reactions. Even so, if you find yourself getting overly emotional about daily fluctuations, this process may not be for you.
Why meat must be part of our diet
- Prehistoric Hunters in a Cave Painting
Vegetarians and vegans like to tell us that we should eat a largely carbohydrate diet. I disagree. They like to say that our diet should resemble that of gorillas and chimpanzees since they are supposedly our nearest evolutionary relatives. But our digestive systems are very different from theirs. Barry Groves explores those differences at length in an article on his site. Our digestive system resembles that of carnivores more than it does that of herbivores.
Dense carbohydrates are a very recent addition to the human diet. Agriculture did not occur until about 10,000 years ago; and in some areas such as northernEurope, agriculture did not arrive until about 5,000 years ago. Prior to that, humans were hunter/gatherers. Modern day hunter/gatherer diets tend to be largely meat-based with a preference for the fattiest portions. It is clear from the bone piles found at sites where prehistoric human remains have been found that the prehistoric diet included a lot of meat as well. Their cave paintings depict hunting, not agriculture. And the bones of those prehistoric humans showed that they were much healthier than us. They were taller, and they did not suffer from degenerative diseases such as arthritis. Those in the northern climates particularly would have been eating a meat diet because the ice age would not have allowed much vegetation to grow.
On the other hand, arthritis, obesity, and heart disease are apparent in Egyptian mummies, a society where grains predominated.

High-fat diet best for weight loss
There was a study done in 1956 comparing weight loss on diets of differing macronutrient content. The diets were all 1,000 calories. One was 90% carbohydrate, another was 90% protein, another was 90% fat, with the last being a mixed diet. Those on the 90% fat diet lost the most weight, with those on the 90% protein diet coming in as a close second. Those on the 90% carbohydrate diet lost the least, and some of those even gained weight.

Master Cleanse
I tried the Master Cleanse with my daughters a couple of years ago. That’s the lemonade cleanse, for those not familiar with it. That turned out to be a REALLY bad idea. It broke my metabolism, and I started gaining lots and lots of weight like crazy beyond what my caloric intake would justify. Nothing would stop it. All I could do was watch while the pounds piled back on. I think the Master Cleanse may have messed up the flora in my intestine. Lately, my weight has stabilized some. I consider the Master Cleanse to be a dangerous diet.
Does the American Heart Association know about these studies?
I continue to read Natural Health & Weight Loss by Barry Groves. I am currently reading about fats.
A study was done in 1965 by Rose GA et al to assess survival rates in patients eating different fats and oils. In this study, patients who had already had a heart attack were assigned to one of three groups. These were given polyunsaturated corn oil, mono-unsaturated olive oil or saturated animal fats respectively. Blood cholesterol levels were lowered by an average of 30% in the polyunsaturated group, while there was no change in the other two groups. At first sight, therefore, it seemed that men in the polyunsaturated group had the best chance of survival. However, at the end of the trial only 52% of the polyunsaturated group were still alive and free of a second heart attack. Those in the mono-unsaturated group fared little better: 57% survived and had no further attack. But the saturated animal fats group fared the best with 75% surviving and without a further attack.
There was also a Finnish trial published in 1985 by Miettinen TA et al in which middle aged men were given interventions such as instruction on diet, smoking, and exercise and were also treated for high blood pressure and cholesterol when present. The control group was given no such interventions. At the 15-year follow-up, there were 67 total deaths and 34 heart disease deaths in the intervention group. In the control group, there were 46 total deaths and 14 heart disease deaths.
Would it be fair to say that we are being given bad advice where it relates to heart health?

Relaxation for weight loss
I found this little tidbit:
A study released by the Georgetown University Medical Center has posited a link between stress and weight gain that is more than just psychological; it seems to be physiological, too. When certain mice were stressed out, they gained far more weight than the control group of calm mice – even when both groups were fed the same amount of calories. After a period of three months the little frazzled guys became twice as obese as their relatively serene little compatriots.
Dr. Zofia Zukowska, who headed up the study, says researchers suspect that this result is due to an enzyme which has been found in especially high amounts in abdominal fat. In other words, the weight gain caused by stress seems to go straight to the belly, the most dangerous place to store fat. So now relaxation therapy is being recommended as a good addition to any weight loss program.
Hypnotherapy is a form of relaxation therapy which can help you with weight control. Not only will it help you reduce stress, but it can also help you correct bad eating habits.
