Trifecta

Posted by Liz on Sep 29, 2008 in weight gain | 2 comments

Midsection weight gain is a hard pill to swallow, especially when you’re doing all the things that experts keep telling you to do, like watching your diet, exercising and limiting indulgences. In fact, it’s been reported that women in their midlife years gain as much as 1.1 pounds yearly over a five-year period, which places the odds of gaining weight about twice the average rate.  So what gives?

Last week, I wrote a post on the importance of moving your body. Several experts chimed in and added that regular weight training and a change in how and what you eat might help to stave off those pounds. In the particular report cited above, researchers wrote that the one pound a year weight gain equated with only an extra 10 calories a day and suggested that small, sustained changes in daily physical activity and diet can prevent further weight gain. Okay, that sounds reasonable, right?

Another study, published last year in the Journal of Clinical Endocrinology & Metabolism, showed that weight gain and changes in waist circumference in midlife are associated with both regular aging and  changes in ovarian function.  The good news in this study was that while waist circumference increased over a 6-year period, the rate of increase slowed one year after the final menstrual period.

BTW, the reason for the buildup of fatty of tissue has to do with balance. That is, as estrogen production declines, the body starts to rely on secondary production sites, such as body fat and skin. So, fatty tissue starts function like an endocrine organ instead of simply a passive vessel for energy storage. The body also struggles to hold onto bone mass and may compensate for its loss by holding on to extra body fat longer.

The news isn’t all bad however.

That ‘Old Black Magic’ has struck again!

Results of an animal study in the journal Maturitas show that black cohosh extract attenuates body weight gain and accumulation of intrabdominal fat and also lowers glucose levels to the same extent as estrogen. The effect on blood fats in this study was a bit more complex; black cohosh extract was associated with higher LDL-cholesterol levels and lower triglyceride levels and estrogen, the exact opposite. The researchers remain uncertain how these effects ultimately influence weight gain as well as associated health risks, such as the metabolic syndrome.

These study results undoubtedly need to be replicated in humans. But they do suggest a potentially viable strategy to battle weight gain: black cohosh.

So, perhaps the trifecta in overcoming menopausal weight gain is diet, exercise and black cohosh. Only time will tell.

The Great Pretender

Back in June, I wrote a post about the dangers of buying herbs for menopause right off the shelves.  Consumerlabs.com is now reporting that testing shows great variation in the amount and quality of herbal menopausal products., including supplements containing black cohosh, soy isoflavones, red clover isoflavones and also, progesterone creams.

For example:

• One supplement contained only 30% isoflavones despite a guarantee and another, only 65% of a specific type.
• Two products failed to comply with FDA labeling that require detailed information on plant parts used as ingredients.
• Lead contamination was found in one product.

On a more positive note, ConsumerLab found that seven soy isoflavone products met their quality standards and provided at least 50 mg to 70 mg total soy isoflavones, which is the amount research has associated with relieving hot flashes.  Additionally,

• Two red clover isoflavone products contained the correct amount (40 mg) associated with hot flash reduction.
• Six black cohosh products met quality standards.
• The progesterone creams tests provided the listed amount of progesterone, which ranged from 15 to 21 mg per gm.

You can read more about the tests at the company website.

So, what’s the take-away message from this research?

As Ellen Stern mentioned during our interview a few months ago, it’s critical to look for standardized herbs, meaning that they have undergone rigorous manufacturing practice and protocols to insure quality. She also recommended that search for “standardized x extract” on the American Botanical Council website. Finally a simple rule of thumb is that the least expensive product is not always going to be the best choice.

That Old Black Magic

Remember black cohosh? That wonderful herb in the buttercup family of plants that is commonly used  to address hot flashes, mood swings, night sweats and other vasomotor symptoms? Black cohosh has been used in traditional folk medicine for centuries and was introduced to the settlers by Native American Indians, who incorporated the herb into their traditional medicines for women’s ailments.

I’ve discussed the utility of black cohosh for sleep and other disturbances in a previous post.

Personally, I’ve been using a standardized black cohosh formulation in combination with some Chinese herbs, (as recommended by acupuncturist and Chinese medicine specialist Elaine Stern)  with great success for many months now. Hence, I am a huge fan. And in my book it is that ‘old black magic.” Still, I believe that it’s important to address warnings that link black cohosh to liver damage. Here’s what you need to know:

Based on recent statements that have been recently issued in Australia and the United Kingdom, The U.S. Pharmacopeia’s Council of Experts extensively analyzed data from 30 case reports, side effects reports and other sources to evaluate the association between black cohosh and liver damage.  They concluded that there was enough evidence from case reports to suggest a possible link and proposed that a cautionary statement be included on manufacturer labeling.

So, what’s the bottom line? Overall, there are been few reports of liver damage but they have provoked enough concern to raise a red flag amongst several regulatory agencies worldwide. Here, the U.S, the National Institutes of Health Office of Dietary Supplements says that millions of people have safely used black cohosh without any apparent negative health effects.

As always, if you choose to go the herbal route, speak to an health professional who is well-versed in herbal medicine first. Try to select standardized formulation (it usually says it right on the label), which can help to insure that optimal and safe manufacturing processes have been followed and that you’re getting a pure form of the herb. Finally, be aware of potential side effects. In addition to liver damage, black cohosh has been linked with headache, dizziness, visual disturbance, constipation and intestinal discomfort, mostly at higher than recommended doses. Finally, remember that herbal medicine is medicine, and like Western preparations, requires vigilence, common sense, and can result in adverse effects if not used correctly.
