Life Extension Weight Loss Blood Test Panel
What “Obesity Factors” Are Keeping You from Losing Weight?
While most aging people accumulate excess body fat, the under-lying causes of weight gain vary considerably amongst individuals. Unless the obesity factors responsible for your weight problem are identified, you’re literally “shooting in the dark” when attempting to shed excess fat pounds. Fortunately, proper blood testing can uncover the specific factors responsible for your unwanted weight gain, so that corrective actions can be taken.
The New Life Extension® Weight Loss Blood Test Panel
Many people have tried to follow low-calorie diets without achieving meaningful reductions in body fat. One reason for these failures is hormone imbalances that can preclude significant weight loss if not corrected.
For example, if you have insufficient levels of T3 (the active thyroid hormone), your cellular metabolism may be too slow to burn off stored fat. In response to eating less, your body responds by further inhibiting T3 production, thus making it even more challenging to rid surplus fat pounds. By measuring TSH (thyroid-stimulating hormone), free T4, and free T3 blood levels, your doctor can optimize your thyroid hormone status to the youthful ranges when you were much thinner. Thyroid hormone deficits are especially prevalent in women.
Abdominal weight gain is epidemic in aging men. Low free testosterone is a common culprit. In women, abdominal fat accumulation may be caused by an estrogen imbalance and/or excess free testosterone (the opposite of men). In both sexes, low DHEA hormone can contribute to excess belly fat. By measuring blood levels of hormones involved in fat metabolism, one can restore their hormonal profile to youthful ranges that existed when you were at normal body weight.
The new Life Extension Weight Loss Blood Test Panel analyzes these hormones (along with other obesity factors) so that you and your doctor have the data to properly restore them to optimal ranges.
Correcting Metabolic Imbalances
Aging results in a reduction in insulin sensitivity that contributes to our bloodstreams being chronically bloated with excess glucose and triglycerides. One might assume that cutting calories would correct this problem, yet many overweight people lack the metabolic capacity to remove excess glucose, triglycerides, and other obesity factors from their blood. It is particularly challenging to lose significant weight while one’s bloodstream is chronically overloaded with fat-inducing compounds.
The Life Extension Weight Loss Blood Test Panel analyzes a host of metabolic parameters that may be blocking your ability to shed body fat. Once identified, proven methods exist that you (and/or your doctor) can implement to purge your bloodstream of these dangerous obesity factors.
Suppressing Chronic Inflammation
Heavy people have startlingly high levels of C-reactive protein, which is a blood marker of chronic inflammation. C-reactive protein contributes to obesity by binding to the leptin hormone. Leptin signals satiety (thereby reducing hunger) and promotes the breakdown of body fat through the process of lipolysis. Suppressing elevated C-reactive protein is an essential element in a scientific weight loss and longevity program.
The Life Extension Weight Loss Blood Test Panel analyzes C-reactive protein levels. If elevated, proven methods exist to reduce C-reactive protein to safer ranges.
