The High Protein Diet

High Protein For Weight Loss, Soy Protein, Green Tea For Better Health

Dieting with high protein meal replacement shakes and bars is a clinically proven way to effectively produce significant sustainable weight loss and improve weight related risk factors of disease.

My blog is an informational blog that will provide you with a healthy way to lose weight. Many clinical studies have proven that drinking high protein shakes during the day will result in rapid weight loss. This two week diet has the potential for rapid weight lose and better health. Repeat The High Protein Diet often.

The WebMD Weight Loss Clinic has published the article: "Can a High Protein Diet Help You Lose Weight". In this article researcher Donald Layman, PhD recommends the eating of 120 grams of protein a day to get the weight loss benefits. The High Protein Diet uses meal replacement shakes and bars and soy protein chips to meet this goal. In addition The High Protein Diet also includes decaf green tea for better health.

Soy Safety

Health experts, including the Food and Drug Administration (FDA) (1) and the American Cancer Society (2) have all weighed in on the safety of soy foods, such as tofu and soymilk, as well as meat and dairy free products such as veggie burgers and soy cheeses. The conclusion: soy foods are low in fat, high in protein, fiber and iron, they contain essential omega-3 fatty acids and are absolutely safe to eat. Here are the facts you need to know:

FACT: The U.S. Food and Drug Administration approved a health claim for foods that contain at least 6.25 grams of soy protein which states that, "25 grams of soy protein a day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease." FDA extensively reviewed research to support this health claim and found that soy protein, when included in a low-fat and low-cholesterol diet, could lower blood total cholesterol and low-density lipoprotein (LDL) or "bad" cholesterol levels. To get 25 grams daily, enjoy three or four servings of soy foods, such as 1 cup of soymilk, 3 to 4 ounces of tofu, one 3 ounce soy burger, 3 ounces of meatless chicken strips or nuggets, 1 cup of soy pasta, 1 cup of cultured soy, 2 tablespoons soy nut butter, a frozen soy bar, a ¼ cup of soy nuts or edamame.

FACT: The isoflavones naturally found in soy benefit human health. Isoflavones are bioactive compounds, and recent studies find that the isoflavones contained in soy foods are associated with such benefits as improving the health of arteries, (3) preventing certain cancers(4, 5) and reducing bone loss. (6) Unfortunately, there has been a lot of confusion resulting from some studies in animals that were given very high concentrations of isoflavones compared to the bioactive compounds that one typically eats in soy foods. Some animal studies that are looking for effects inject or feed a very concentrated source of one specific isoflavone, such as genistein, which is very different from the way isoflavones are consumed in food. (7) Applying these study findings is like mixing apples and oranges. Other problems seen in some animals but not humans are believed to be due to differences between humans and animals in the way soy isoflavones are metabolized.(8)

FACT: Isoflavones in soy foods have no significant effects on hormone levels in men or women. Although isoflavones are called "phytoestrogens" because they look similar to the chemical structure of estrogens, they can act differently in the human body and shouldn't be confused with the estrogen hormone. As a result, there is no validity to the claim that consuming soy leads to testosterone levels that are lower than normal. In fact, a recent study involving active young men found that soy protein did not lower testosterone concentrations in comparison to control groups, but did produce a beneficial antioxidant effect.(9) Other studies in people found that men consuming 40-70 mg/day of soy isoflavones from soy foods or soy supplements had no significant changes in testosterone levels compared to control groups.(10,11,12)

FACT: Soy foods are safe for the developing fetus. According to a scientific panel convened in March 2006 by the National Institute of Environmental Health Sciences (NIEHS), even pregnant women who eat soy regularly consume such low amounts of genistein, the most heavily concentrated isoflavone in soy, that the likelihood of reproductive or developmental effects are of "negligible concern."(13) Such problems have only been observed in targeted studies on animals, not humans, using very large amounts of genistein.

FACT: Women who eat soy foods have a lower risk of developing breast cancer. Eating soy foods appears to have a protective effect against developing breast cancer at any age, which may be strongest when soy is consumed during childhood and adolescence. (14,15, 4) This may be a major reason why Asian diets are linked to lower breast cancer death rates. Observations have found that Asian women who follow a traditional Asian diet have a much lower breast cancer rate: in one estimate, one-fifth that of Western women.(16)

FACT: No studies demonstrate a link between eating soy and breast cancer recurrence or tumor growth in humans. Because some studies in mice observed that very high levels of soy protein or isoflavones led to faster tumor growth or recurrence, this has been an area of study in women, but to date there have been no studies in humans that demonstrate a link between eating soy and tumor recurrence or growth. Nor has soy or its bioactive compounds been observed to cause changes associated with breast cancer, such as thickening breast tissue,(17,18,19) increasing the number of cells in breast tissue,(20) or increasing estrogen circulating in the blood.(21) Researchers also make it clear that it is difficult to apply findings from animal studies using excessive doses of isoflavones to humans because mice and rats produce lower levels of hormonal estrogen than do women,(22) and the digestion of isoflavones produces different end products.(23)

FACT: Major national institutes for cancer research and treatment advise that breast cancer survivors can safely consume moderate amounts of soy. The National Cancer Institute(24) states that for breast cancer survivors "soy foods, as part of a healthy diet and in moderate amounts, are safe to consume." The American Cancer Society suggests up to 3 servings a day is safe, while the American Institute for Cancer Research(25) advises women who have had hormone-dependent breast cancer to limit themselves to a few servings of soy foods per week. All agencies specify that these recommendations apply to whole soy foods, and do not advise consumption of supplements of soy protein or isoflavones. Additionally, those who are taking tamoxifen should consult their oncologists for advice on soy and other matters concerning nutrition, since animal studies have shown that isoflavones can alter the actions of tamoxifen.(26)

FACT: Soy foods protect against thyroid cancer and have no effect on thyroid function in healthy people. A recent study indicates that eating soy foods may actually protect against the development of thyroid cancer in women.(27) More research needs to be conducted to determine if these benefits are consistent in men and women. Moreover, in a recent review of clinical trials involving healthy men and women, the weight of the evidence found that consuming soy foods or isoflavones had either no effects or only very modest changes (but within normal range) on thyroid function.(28) It is important to note that the adults studied in these trials got enough iodine in their diet. In other studies or observations that linked soy food consumption to goiter, iodine deficiencies, rather than soy, were to blame.(29)

FACT: Soy foods are safe for people with hypothyroidism (under-active thyroid) who are under medical care. Although people who are being treated for hypothyroidism need to discuss their diet with their physician so that an appropriate level of medication is prescribed, soy foods can be consumed safely. Soy foods are among many commonly eaten foods, including high-fiber foods as well as iron and calcium supplements (30) that have chemical components which can affect to some extent medication for hypothyroidism. Some physicians suggest taking the medication between meals, so that the chemical components in food do not interfere with the actions of the medicine.(31)
