To explain what hemoglobin A1c is, think in simple terms. Sugar sticks, and when it's around for a long time, it's harder to get it off. In the body, sugar sticks too, particularly to proteins. The red blood cells that circulate in the body live for about three months before they die off. When sugar sticks to these hemoglobin proteins in these cells, it is known as glycosylated hemoglobin or hemoglobin A1c (HBA1c). Measurement of HBA1c gives us an idea of how much sugar is present in the bloodstream for the preceding three months. In most labs, the normal range is 4%-5.9 %. In poorly controlled diabetes, its 8.0% or above, and in well controlled patients it's less than 7.0% (optimal is <6.5%). The benefits of measuring A1c is that is gives a more reasonable and stable view of what's happening over the course of time (three months), and the value does not vary as much as finger stick blood sugar measurements. There is a direct correlation between A1c levels and average blood sugar levels as follows.
No magic here—MRT is just a term covering various combinations of intense, efficient cardiovascular and muscular training. MRT can involve supersets, circuits, speed, low rest and compound movements; it almost always packs a double-punch of aerobic and anaerobic work, breaking down barriers between traditional weight training and cardio. If you're sick of long rest periods and the sleepy treadmill slump, MRT might be for you.
Along with the increased hunger and cravings comes the metabolic slow down. This is most impacted by the hormone leptin. Less insulin exposure to the fat cell and a shrinking fat cell means the metabolic hormone leptin is reduced. Low leptin means increased hunger. Low leptin also means decreased activity of the body’s two major metabolic engines, the thyroid and the adrenal glands. So as leptin decreases, your metabolism gets the signal to stop burning energy and to start consuming it.
The key sign of metabolic syndrome is central obesity, also known as visceral, male-pattern or apple-shaped adiposity. It is characterized by adipose tissue accumulation predominantly around the waist and trunk. Other signs of metabolic syndrome include high blood pressure, decreased fasting serum HDL cholesterol, elevated fasting serum triglyceride level, impaired fasting glucose, insulin resistance, or prediabetes. Associated conditions include hyperuricemia; fatty liver (especially in concurrent obesity) progressing to nonalcoholic fatty liver disease; polycystic ovarian syndrome in women and erectile dysfunction in men; and acanthosis nigricans.
Many of you at this point know my story, for the entirety of my life I had tried diet after diet. I was active, I ate well, yet no one would believe that because I was obese. Indeed, my poor mother dragged me from doctor to doctor trying to figure out what was going on with me. She was desperately trying to help me understand why nothing I did worked and why year after year I gained more and more weight and felt less at home in my body. I know that I am not alone in this as so many of you have reached out to tell me that they are struggling with weight loss. This phenomenon, that I have titled weight loss resistance, is a huge concern to me! This was part of the reason I became a Naturopathic Doctor. In the days when no one could help me shed the extra 80lbs of body fat I had, I had to do my own research, I had to blaze my own trail and now I am compelled to share that!
Let me give you an example of this. A person decides to follow a low calorie diet. They determine that their resting metabolic rate is 2000 calories per day. They decide, according to conventional wisdom, to reduce their daily calorie intake by 500 calories per day. Now they are consuming 1500 calories per day. They remain compliant and in a few weeks have lost a few pounds.
Weight loss surgery in those with obesity and type two diabetes is often an effective measure. Many are able to maintain normal blood sugar levels with little or no medications following surgery and long-term mortality is decreased. There is, however, a short-term mortality risk of less than 1% from the surgery. The body mass index cutoffs for when surgery is appropriate are not yet clear. It is recommended that this option be considered in those who are unable to get both their weight and blood sugar under control.
This is an incredibly important, but commonly overlooked factor that heavily influences a metabolic resistance training program's success. While you can usually get by with minimal equipment with a MRT program, body weight only can get old very quickly. Fortunately, just adding a kettlebell, band, suspension trainer, barbell, or other implement can quickly expand your exercise selection pool. It's important to realize that a little bit can go a long way, especially if you're training in a busy gym and can't monopolize pieces of equipment for too long without someone walking off with them!
Metabolic syndrome is a cluster of metabolic risk factors that come together in a single individual. These metabolic factors include insulin resistance, hypertension (high blood pressure), cholesterol abnormalities, and an increased risk for blood clotting. Affected individuals are most often overweight or obese. An association between certain metabolic disorders and cardiovascular disease has been known since the 1940s.
