How To Lose Weight Without Losing Bone

ScienceDaily (2008-06-06) -- A higher-protein diet that emphasizes lean meats and low-fat dairy foods as sources of protein and calcium can mean weight loss without bone loss -- and the evidence is in bone scans taken throughout a new study. ... > read full article
 
So with these thoughts in mind -- consider having those of your clients who are embarking on a weight loss program get their Vitamin D status checked and maintain their calcium and protein intake.  Standard Process NEW Bone Health daily fundimentals packets may assist your clients in this area in that they have Calcifood wafers and Cataplex D in them. If your clients are embarking on a purification program then the addition of Whey Pro Complete can help them provide the minimum protein required for optimal uptake of calcium. Dietary protein intakes at and below 0.8 g/kg were associated with a probable reduction in intestinal calcium absorption http://www.ncbi.nlm.nih.gov/pubmed/12936953.  The combination of all three (Vitamin D, Calcium, Whey Protein) resulted in weight loss regardless of levels of calories from fat or sucrose http://www.nrjournal.com/article/S0271-5317(08)00188-7/abstract.

Food Falicies

Check the Fine Print for these Common Food Fallacies


Bonnie Taub-Dix, registered dietitian, weight loss expert, and author of the new Read It Before You Eat It interprets the often-misleading markers on your favorite snacks.

Catches Your Eye: 0g trans fat
Look Closer: Trans fat-up to 0.5 grams in each unreasonably tiny portion

Why: “This is a labeling loophole,” says Taub-Dix. “Under FDA regulations, this claim is true even for products containing trans fat. Look at the ingredients on the back-if ‘hydrogenated oil’ or ‘partially hydrogenated oil’ are listed, it does have trans fat. Under current FDA regulations, manufacturers can include this label as long as the product contains less than 0.5 grams trans fat per serving.”

Catches Your Eye: Gluten-free
Look Closer: Trace amounts of wheat protein

Why: “Even though a product may have been fine for your allergy before, manufacturers change formulas, and it may no longer be safe. If you have food allergies, check the ‘May Contain’ statement under the ingredients every time. The eight allergens manufacturers must acknowledge are: milk, eggs, crustacean shellfish, tree nuts, wheat, peanuts, soy, and fish.”

Catches Your Eye: Vegetarian
Look Closer: A product that may contain fish

Why: “Vegetarians and vegans often look for kosher foods with the label ‘parve’-meaning the product contains no meat or dairy products. What they may not realize is that these items can still contain eggs, fish, or honey.”

Catches Your Eye: Organic
Look Closer: No information about nutritional content.

Why: “Many people feel ‘organic’ equals ‘healthy.’ Don’t be fooled: ‘Organic’ only reveals how it was grown and processed; it doesn’t communicate anything about the product’s nutrients or whether or not it was grown locally. Thirty percent of ‘organic’ products are imported from China. The organic versions of some produce are better because inorganic produce is more likely to be contaminated with pesticides.”

Catches Your Eye: All Natural
Look Closer: A definition meant for meat and poultry, applied to everything from potato chips to frozen yogurt.

Why: “The USDA created this label for meat and poultry; it has not been defined by the FDA. If you see it on anything other than meat and poultry, it has virtually no significance. Sugar is natural, so it’s OK to label something with a lot of sugar as ‘all natural’.”

Vitamin D and Athletic Performance

Bioletics www.bioletics.com.

An optimum level of vitamin D is an absolute essential for any athlete. Recent research has proven that vitamin D boosts immunity, hormonal activity, brain function and metabolism. It promotes muscular strength, speeds recovery and enhances both reaction time and balance.

In order to understand how vitamin D may impact your athletic performance, it is important to know that the active form of vitamin D is actually a hormone that, in many ways, acts like testosterone or growth hormone. It works directly at the cellular level of your body, directing all physical processes related to growth, repair and performance.

Although vitamin D can be obtained in small amounts from the food we eat, the sun is a better source. When UVB rays penetrate the skin, they unlock the body’s ability to make its own supply of vitamin D.

The human body can make thousands of units of vitamin D with the proper amount exposure to sunlight. When sunbathing during the summer months, the body can naturally produce about 20,000 IU’s of vitamin D—the same amount of vitamin D in 200 glasses of milk or the equivalent of that found in about 50 multivitamins.

Most athletes, however, don’t come close to getting enough sun to satisfy their bodies’ vitamin D needs—not even those who spend several hours training outside every day. Approximately 75% of all athletes are vitamin D deficient. Chances are, you’re deficient in vitamin D, too.

Your body requires 4,000 IU’s daily, just to maintain its current vitamin D level. In order to actually raise it, you’ll need to increase your amount of sun exposure (which isn’t always practical or possible, especially during the winter months) or take an oral vitamin D3 supplement.

A few words of advice:

Do NOT take vitamin D2 supplements. This unnatural from of vitamin D is 50% less effective than vitamin D3 and is metabolized into potentially-toxic substances. Vitamin D2 is very expensive and only available by prescription

Two very important things to remember:

1. It is absolutely essential that you get your vitamin D levels assessed regularly (a simple finger stick is all that’s required). While the body will not produce more vitamin D than it needs, it is possible to take too much vitamin D orally.

Optimal levels of vitamin D fall within the range of 50-65 ng/ml (nanograms per milliliter). To safely and accurately determine your needs, first establish your baseline level. After following a vitamin D supplementation program for three months, repeat the assessment. Once your levels have reached an optimal range, switch to a maintenance dose. Then, consider assessing yourself at regular intervals in March (following winter when your level is likely to be at its lowest) and August/September (when it is likely to be a its highest).

An inexpensive, at-home assessment kit can purchase at www.bioletics.com

2. There is no optimal dose of vitamin D. Because you are a biologically-unique individual, your need for vitamin D (from either the sun or supplementation) will be different from any other athlete’s. The approximate dosage of vitamin D needed to maintain a blood level between 50-80ng/ml is 1,000 units of vitamin D3 per 25 pounds of body weight daily. But it may take double—or triple—that amount to raise your level if it is very low.

We are only beginning to realize what our bodies have intuitively known for thousands of years—the sun provides us with tremendous healing and performance potential. Restoring optimal vitamin D levels with regular and managed exposure to UV light and/or oral supplementation is one of the most important things you can do for your athletic body.
