Estradiol (E2) (Estrogen - Oestrogen)
Estradiol (Estrogen) is at optimal physiological levels in women promotes a healthy distribution of fat in hips, thighs, breasts, and under the skin (subcutaneously). However, in excess and the absence of progesterone, oestrogen predisposes to unhealthy surplus weight gain in these tissues. Men generally have much lower levels of estradiol and higher testosterone, which is responsible for greater muscle mass and less fat distribution in areas of the body normally seen in women. In overweight men testosterone levels drop, and oestrogens raise leading to the same problematic weight gain in the hips, thighs, and breasts (referred to as gynecomastia) as seen in women.
Progesterone is in addition to keeping oestrogen levels in check, aids weight management by supporting thyroid metabolism, helping the body use and eliminate fats, and acting as a natural diuretic. In the proper ratios, progesterone and oestrogen help to control the way insulin is released and body fat stored. As the precursor of cortisol, progesterone supports adrenal regulation of blood glucose, while its natural calming properties may relieve stress-related overeating and food cravings.
Testosterone (T) And DHEAS (DS)
Testosterone and DHEA-S (DS) are androgens that increase lean muscle mass and metabolic rate. As androgen levels decline, muscle mass also decreases with a corresponding increase in adiposity. Low androgens can also reduce vitality and tolerance for exercise. Weight gain itself, with its resulting hormone imbalances; can trigger a drop in testosterone in men. The aromatase enzyme within fat tissue converts androgens to oestrogens, contributing to a female-type body fat distribution, including breast tissue development. In women with the polycystic ovarian syndrome (PCOS), high testosterone and DHEA are linked to insulin resistance and weight gain, particularly in the abdomen.
Imbalances can create problems with blood sugar control, sleep patterns, appetite, food cravings, and exercise tolerance. Under stress, excessive cortisol production, particularly in concert with insulin, promotes fat storage in abdominal adipose tissue. This visceral type of fat is closely associated with insulin resistance and metabolic syndrome and thus more hazardous to health. Chronically elevated cortisol is a known risk factor for pre-diabetes and cardiovascular disease.
Thyroid Stimulating Hormone (TSH)
TSH elevations, even within the high-normal range, are linked with hypothyroidism, low metabolic rate and obesity. Hypothyroidism is linked to elevated cortisol and can also be a consequence of oral oestrogen therapy, which increases the production of binding proteins that reduce thyroid hormone bioavailability.
Vitamin D (D2, D3)
Vitamin D deficiency is common in obesity and particularly associated with hyperinsulinemia and visceral fat. Whether by cause or effect, identifying and correcting vitamin D2 and D3 deficiency may improve insulin sensitivity.
Most people are familiar with vitamin D’s role in preventing rickets in children and in helping the body absorb calcium from the diet.
Recently, research has shown that vitamin D is important in protecting the body from a wide range of diseases. Disorders linked with vitamin D deficiency include:
- Cardiovascular disease
- Several forms of cancer
- Some autoimmune diseases such as multiple Sclerosis
- Rheumatoid Arthritis
- Type I Diabetes & Type II Diabetes
- Breast and Colon Cancer (linked to Vitamin D Deficiency)
- Depression and even schizophrenia
Vitamin D is actually a prohormone and not technically a vitamin: a vitamin is defined as a substance that is not made naturally by the body but must be supplied in the diet to maintain life processes. But in fact, we make most of our vitamin D by the action of ultraviolet light (sunlight) on the vitamin D originator that is found in our skin. We only get very small amounts of vitamin D from our diet, although increasingly it is added to foods eaten by children, in an attempt to prevent rickets in the population
Total Cholesterol (CH)
Cholesterol is required by the body as a precursor to steroid hormone synthesis and as a component of cell membranes. However, in excessive amounts, it is a strong component of coronary heart disease risk because of its contribution to coronary atherosclerosis. Atherosclerotic plaque is largely composed of cholesterol. As with other risk factors, high blood cholesterol levels are more significant when other cardiometabolic parameters are already abnormal, or in patients who already have diabetes or cardiovascular disease. The current National Cholesterol Education Program recommendations for total cholesterol levels are: <200 mg="" dl="borderline" 200="" -="" 239="" high="" data-mce-fragment="1">240 mg/dL = high.
Triglycerides enter the circulation as the end-product of digesting dietary fat, and they are also synthesized by the liver. They are an important energy source for the body and are stored in fat cells. Elevated blood levels, or hypertriglyceridemia, often found in untreated diabetes and obesity, are an established indicator of atherogenic dyslipidemia. The National Cholesterol Education Program defines fasting triglyceride levels of 150 mg/dL or above as one of the diagnostic criteria for metabolic syndrome, although some studies have shown that fasting levels lower than 100 mg/dL should be considered as a more optimal cutoff in coronary heart disease risk assessment. The inflammatory state leading to the development of atherosclerosis may be triggered by “postprandial dysmetabolism,” a condition characterized by unusually high levels of glucose and triglycerides after a meal. Postprandial hypertriglyceridemia indicates the presence of remnant lipoproteins, which are believed to promote atherosclerosis, and it is also linked with insulin resistance and obesity. Several studies have found that triglyceride levels measured 2-4 hours after a meal are highly predictive of cardiovascular events, especially in women. Nonfasting levels >200 mg/dL are suggestive of postprandial dysmetabolism.
HDL Cholesterol (HDL)
Cholesterol bound to high-density lipoprotein (HDL) in the blood is known as HDL cholesterol. A low level of circulating HDL cholesterol is one of the established criteria for the diagnosis of metabolic syndrome and has long been regarded as a powerful predictor of cardiovascular disease in both diabetics and non-diabetics. In a large cohort from the Framingham Study, a high total cholesterol/HDL cholesterol or LDL cholesterol/HDL cholesterol ratio was associated with increased coronary heart disease risk, and a high HDL cholesterol level was associated with reduced risk, in both men and women. Currently, the LDL cholesterol/HDL cholesterol ratio is regarded as a reliable tool for the evaluation of cardiovascular disease risk. While absolute values of each are still considered by the National Cholesterol Education Program (NCEP) as the optimal diagnostic indicators, the ratios that are currently accepted by doctors and researchers are as follows: total cholesterol:HDL cholesterol ratio – optimally below 4; LDL cholesterol:HDL cholesterol ratio – optimally below 3. The current NCEP recommendation to reduce the risk of cardiovascular disease is to maintain an HDL cholesterol level >40 mg/dL in both men and women.
Sex Hormone Binding Globulin (SHBG)
SHBG binds and transports both testosterone and estrogens in the bloodstream, and it therefore regulates the relative amounts of free and bound hormone and consequently their bioavailability to target tissues. SHBG is a protein produced by the liver in response to exposureto any type of estrogen. Testosterone binds about three times more tightly to SHBG than does estradiol, so this increase in SHBG as a result of estrogen exposure causes the relative proportion of bioavailable testosterone to estradiol to decrease even further, exacerbating the symptoms of testosterone deficiency. Many factors, in addition to estrogen exposure, can affect SHBG levels. Thyroid hormone increases SHBG production, whereas insulin, on the other hand, decreases SHBG levels. In young men, testosterone levels are usually high and SHBG low, making most of the testosterone bioavailable. However, as men age, gain weight, and their estrogen levels increase, SHBG also rises, decreasing bioavailable testosterone. Measuring SHBG in blood provides an indication of the overall exposure to estrogens, as well as the bioavailable (free) fraction of testosterone (calculated from the ratio of testosterone to SHBG).
