What is Metabolic Syndrome?
Metabolic syndrome is not a disease in itself but a set of risk factors:
- insulin resistance (See below for more)
- high blood pressure
- high blood sugar
- high LDL (bad) cholesterol
- abdominal fat
Individually these are not so bad, having two of them ups your risk for diabetes and heart disease. Three factors is required for a diagnosis of metabolic syndrome. There are some variations of the criteria, but this is a pretty standard one.
Now we come to the problem: insulin resistance. This is a dysfunction in which healthy cells (like fat and muscle) have reduced ability to use glucose in the presence of insulin. As a result, more and more insulin is produced by the pancreas. Eventually, this causes the pancreas to simply fail and then type 2 diabetes ensues. Among other issues are sharp weight gain at the same time there is an inability to utilize glucose, so the body starves at the cellular level while accumulating fat. You are constantly, gnawingly hungry getting fatter and fatter all the time and attempting to eat less gives you a host of unwanted symptoms associated with starvation. It is very difficult indeed to reverse this once it happens.
How people become insulin resistant is very well understood: Too many carbohydrates too often, especially ones with a high glycemic index (which just means they are readily converted to glucose). Kids who binge constantly on sugar can develop it and there are now many recorded cases of teenagers getting adult onset diabetes, which was unknown even 50 years ago in that age group. A low fat diet, as mentioned above, will reduce fatty deposits from arteries, but also will begin making people much more insulin resistant. Low fat diets were used as short-term therapy for quite some time before becoming a fad. Now people are on them non-stop and metabolic syndrome as well as a sharp increase in the national waistline seem to be the result. Note too that the country with the most abnormally high levels of heart disease and diabetes is India, where strict vegetarian cooking is the norm. (To make this more real for you, diabetes and heart disease occur 10 – 15 years earlier in India, and nearly 1/3 of all a fatalities in India are due to this. In the US, the rate is slightly less than 1/4. It is estimated by the WHO that by 2020 60% of all heart attack fatalities worldwide will be in India. It is referred to now as the “cardiac crisis in India”.) In theory vegetarian diets can be very similar to non-vegetarian diets, but in practice, they tend to be extremely carbohydrate heavy. I was married to a vegetarian for many years and did much of the cooking, so I know.
The major problem is the definition of what is healthy. “Healthy” now refers to a highly sedentary, middle-aged office worker. They are the ones who develop insulin resistance and metabolic syndrome and are the one who require the highest amount of health care. Rather than teach people to listen to their bodies and treat food as fuel — which is hard and requires they take ownership of their health — the baseline for healthy has been redefined. There are also the usual list of agenda driven groups pushing for this or that program. If your activity levels allow it, train hard, eat right (and lots) and enjoy good health. If they do not, you are probably stuck with whatever the doctor prescribes to offset years of inactivity and poor eating. Any advice that does not directly relate your activity levels and specific health concerns to nutritional requirements is probably just ideology and should be treated with enormous skepticism.
