Low blood sugar (hypoglycemia) is common in people with type 1 and type 2 DM. Most cases are mild and are not considered medical emergencies. Effects can range from feelings of unease, sweating, trembling, and increased appetite in mild cases to more serious effects such as confusion, changes in behavior such as aggressiveness, seizures, unconsciousness, and (rarely) permanent brain damage or death in severe cases.[24][25] Moderately low blood sugar may easily be mistaken for drunkenness;[26] rapid breathing and sweating, cold, pale skin are characteristic of low blood sugar but not definitive.[27] Mild to moderate cases are self-treated by eating or drinking something high in sugar. Severe cases can lead to unconsciousness and must be treated with intravenous glucose or injections with glucagon.[28]
The word mellitus (/məˈlaɪtəs/ or /ˈmɛlɪtəs/) comes from the classical Latin word mellītus, meaning "mellite"[114] (i.e. sweetened with honey;[114] honey-sweet[115]). The Latin word comes from mell-, which comes from mel, meaning "honey";[114][115] sweetness;[115] pleasant thing,[115] and the suffix -ītus,[114] whose meaning is the same as that of the English suffix "-ite".[116] It was Thomas Willis who in 1675 added "mellitus" to the word "diabetes" as a designation for the disease, when he noticed the urine of a diabetic had a sweet taste (glycosuria). This sweet taste had been noticed in urine by the ancient Greeks, Chinese, Egyptians, Indians, and Persians.

Metabolic syndrome is increasing in prevalence, paralleling an increasing epidemic of obesity. In the United States, where almost two thirds of the population is overweight or obese, more than one fourth of the population meets diagnostic criteria for metabolic syndrome. [25] In the United States, data from a 1999-2000 survey showed that the age-adjusted prevalence of metabolic syndrome among adults aged 20 years or older had risen from 27% (data from 1988-1994) to 32%. [26]

In the US, 84.1 million adults—more than 1 in 3—have prediabetes, and 90% of them don’t know they have it. Prediabetes is a serious health condition where blood sugar levels are higher than normal, but not high enough yet to be diagnosed as diabetes. Prediabetes increases your risk for type 2 diabetes, heart disease, and stroke. But through the CDC-led National Diabetes Prevention Program, you can learn practical, real-life changes that can cut your risk for developing type 2 diabetes by as much as 58% (71% if you’re 60 or older).
At the end of the twelve-week study both groups lost weight, but the difference in the amount of muscle vs. fat loss was telling. The aerobic group lost 37 pounds over the course of the study. Ten of those pounds came from muscle. In contrast, the resistance-training group lost 32 pounds. None of the weight they lost came from muscle. When the resting metabolic rate of each group was calculated, the aerobic group was shown to be burning 210 fewer calories per day. The resistance-training group avoided this metabolic decline and instead was burning 63 more calories per day.
For an accurate diagnosis of hypertension to be made, it is essential for proper blood pressure measurement technique to be used.[76] Improper measurement of blood pressure is common and can change the blood pressure reading by up to 10 mmHg, which can lead to misdiagnosis and misclassification of hypertension.[76] Correct blood pressure measurement technique involves several steps. Proper blood pressure measurement requires the person whose blood pressure is being measured to sit quietly for at least five minutes which is then followed by application of a properly fitted blood pressure cuff to a bare upper arm.[76] The person should be seated with their back supported, feet flat on the floor, and with their legs uncrossed.[76] The person whose blood pressure is being measured should avoid talking or moving during this process.[76] The arm being measured should be supported on a flat surface at the level of the heart.[76] Blood pressure measurement should be done in a quiet room so the medical professional checking the blood pressure can hear the Korotkoff sounds while listening to the brachial artery with a stethoscope for accurate blood pressure measurements.[76][77] The blood pressure cuff should be deflated slowly (2-3 mmHg per second) while listening for the Korotkoff sounds.[77] The bladder should be emptied before a person's blood pressure is measured since this can increase blood pressure by up to 15/10 mmHg.[76] Multiple blood pressure readings (at least two) spaced 1–2 minutes apart should be obtained to ensure accuracy.[77] Ambulatory blood pressure monitoring over 12 to 24 hours is the most accurate method to confirm the diagnosis.[78]
Moreover, it is estimated that 1 death is prevented per 11 patients treated for stage 1 hypertension and other cardiovascular risk factors when a sustained reduction of 12 mm Hg in systolic BP over 10 years is achieved. [2] However, for the same reduction is systolic BP reduction, it is estimated that 1 death is prevented per 9 patients treated when cardiovascular disease or end-organ damage is present. [2]
Kidney damage from diabetes is called diabetic nephropathy. The onset of kidney disease and its progression is extremely variable. Initially, diseased small blood vessels in the kidneys cause the leakage of protein in the urine. Later on, the kidneys lose their ability to cleanse and filter blood. The accumulation of toxic waste products in the blood leads to the need for dialysis. Dialysis involves using a machine that serves the function of the kidney by filtering and cleaning the blood. In patients who do not want to undergo chronic dialysis, kidney transplantation can be considered. https://www.lorilynnsmith.com/wordpress/wp-content/uploads/2012/04/2012-04-30_2116.png
Diabetes mellitus occurs throughout the world but is more common (especially type 2) in more developed countries. The greatest increase in rates has however been seen in low- and middle-income countries,[101] where more than 80% of diabetic deaths occur.[105] The fastest prevalence increase is expected to occur in Asia and Africa, where most people with diabetes will probably live in 2030.[106] The increase in rates in developing countries follows the trend of urbanization and lifestyle changes, including increasingly sedentary lifestyles, less physically demanding work and the global nutrition transition, marked by increased intake of foods that are high energy-dense but nutrient-poor (often high in sugar and saturated fats, sometimes referred to as the "Western-style" diet).[101][106] The global prevalence of diabetes might increase by 55% between 2013 and 2035.[101] https://www.pickthebrain.com/blog/wp-content/uploads/2013/03/meditation.png
Type 2 diabetes: Type 2 diabetes affects the way the body uses insulin. While the body still makes insulin, unlike in type I, the cells in the body do not respond to it as effectively as they once did. This is the most common type of diabetes, according to the National Institute of Diabetes and Digestive and Kidney Diseases, and it has strong links with obesity.
Type 2 diabetes was also previously referred to as non-insulin dependent diabetes mellitus (NIDDM), or adult-onset diabetes mellitus (AODM). In type 2 diabetes, patients can still produce insulin, but do so relatively inadequately for their body's needs, particularly in the face of insulin resistance as discussed above. In many cases this actually means the pancreas produces larger than normal quantities of insulin. A major feature of type 2 diabetes is a lack of sensitivity to insulin by the cells of the body (particularly fat and muscle cells). http://www.clairekerslake.com/wp-content/uploads/2014/03/ipad_new.png

It’s a tough workout style, but well worth the effort. Typical strength-training programs are either heavy and slow or fast and light. This one’s both heavy and fast. Follow Cosgrove’s system to the letter, keeping your weights heavy and your rest periods short, and you’ll turn your metabolism into a fat-burning furnace. And you’ll build yourself some functional, head-to-toe strength and fitness at the same time.

(As a side note, one tricky thing we are coming to find with leptin is that many obese people have very high circulating levels of leptin but some how their body still doesn’t listen to the signal. They are leptin resistant. This means that your metabolism slows and your hunger gets jacked up… even though you have plenty of fat stores on your body! Talk about frustrating… but solvable!)
As you lose weight your leptin levels drop, signalling to your body that it should probably start to slow things down. In this case you can feel hungry all of the time, but also sluggish and weight loss stops. Some people even see weight gain which can either send you into frustration nation… or alternatively lead you to cut more calories and drive your metabolic rate and gut hormone signalling down even further! Yikes!

Practice relaxation or slow, deep breathing. Practice taking deep, slow breaths to help relax. There are some devices available that promote slow, deep breathing. According to the American Heart Association, device-guided breathing may be a reasonable nondrug option for lowering blood pressure, especially when anxiety accompanies high blood pressure or standard treatments aren't well-tolerated. https://www.clairekerslake.com/wp-content/uploads/2012/05/claire3.jpg
The classic oral glucose tolerance test measures blood glucose levels five times over a period of three hours. Some physicians simply get a baseline blood sample followed by a sample two hours after drinking the glucose solution. In a person without diabetes, the glucose levels rise and then fall quickly. In someone with diabetes, glucose levels rise higher than normal and fail to come back down as fast.

Now let’s say they are one of those people that has a very large metabolic compensation. So large that it equals or exceeds the 500 calorie deficit they were following. At this point not only will all progress stall, but the person may even start gaining weight. This is something the calorie zealots will never tell you, and if you don’t want to take my word for it, follow the links throughout this blog, or read the very nice free review article out of the International Journal of Obesity posted in the references.
The 1989 "St. Vincent Declaration"[117][118] was the result of international efforts to improve the care accorded to those with diabetes. Doing so is important not only in terms of quality of life and life expectancy but also economically – expenses due to diabetes have been shown to be a major drain on health – and productivity-related resources for healthcare systems and governments.
On physical examination, hypertension may be associated with the presence of changes in the optic fundus seen by ophthalmoscopy.[22] The severity of the changes typical of hypertensive retinopathy is graded from I to IV; grades I and II may be difficult to differentiate.[22] The severity of the retinopathy correlates roughly with the duration or the severity of the hypertension.[20]
Stand tall with feet shoulder-width apart. Hold a dumbbell vertically next to chest with both hands cupping the dumbbell head. Lower body as far as you can by pushing hips back and bending knees. Pause, then push back to the starting position and repeat, keeping weight in heels, not toes, during the entire movement. Elbows should point down to the floor and brush insides of knees as you lower.
Blood pressure (BP) is the force that blood exerts on the walls of the arteries. It depends on the strength and rate of the heart's contraction as it pumps blood and on the resistance to the flow of blood through the arteries. The amount of resistance depends on the elasticity and diameter of the blood vessels and the volume of blood flowing through them. The narrower the arteries and the more blood pumping through them, the higher the blood pressure will be. Maintaining a healthy lifestyle can help delay or prevent hypertension.
Target organ damage occurs through multiple mechanisms in metabolic syndrome. The individual diseases leading to metabolic syndrome produce adverse clinical consequences. For example, hypertension in metabolic syndrome causes left ventricular hypertrophy, progressive peripheral arterial disease, and renal dysfunction. [12] However, the cumulative risk for metabolic syndrome appears to cause microvascular dysfunction, which further amplifies insulin resistance and promotes hypertension. [13]
Most drugs take 4–8 weeks for maximum effect. Thus, it is recommended that a minimum period of 6 weeks is trialled before changes to medications are made.Generally treatment starts with a single drug. Recent large studies have shown that cheaper, older drugs, are just as effective as newer drugs. If a single drug fails to achieve blood pressure goals, other agents can be added in.
Metabolic syndrome is a burgeoning global problem. Approximately one fourth of the adult European population is estimated to have metabolic syndrome, with a similar prevalence in Latin America. [25] It is also considered an emerging epidemic in developing East Asian countries, including China, Japan, and Korea. The prevalence of metabolic syndrome in East Asia may range from 8-13% in men and from 2-18% in women, depending on the population and definitions used. [29, 30, 31]
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.
Diabetes can occur temporarily during pregnancy, and reports suggest that it occurs in 2% to 10% of all pregnancies. Significant hormonal changes during pregnancy can lead to blood sugar elevation in genetically predisposed individuals. Blood sugar elevation during pregnancy is called gestational diabetes. Gestational diabetes usually resolves once the baby is born. However, 35% to 60% of women with gestational diabetes will eventually develop type 2 diabetes over the next 10 to 20 years, especially in those who require insulin during pregnancy and those who remain overweight after their delivery. Women with gestational diabetes are usually asked to undergo an oral glucose tolerance test about six weeks after giving birth to determine if their diabetes has persisted beyond the pregnancy, or if any evidence (such as impaired glucose tolerance) is present that may be a clue to a risk for developing diabetes.
Enlarged heart. High blood pressure increases the amount of work for your heart. Like any heavily exercised muscle in your body, your heart grows bigger (enlarges) to handle the extra workload. The bigger your heart is, the more it demands oxygen-rich blood but the less able it is to maintain proper blood flow. As a result, you feel weak and tired and are not able to exercise or perform physical activities. Without treatment, your heart failure will only get worse.
When it comes to laboratory values, numbers like blood glucose and A1C levels are commonly checked. Less often, doctors order a test for your fasting insulin level; yet this test can help predict your risk of developing prediabetes and metabolic syndrome. Insulin plays a key role in metabolism, and high insulin levels can promote obesity, stimulate hunger, and increase the storage of fat.

POPs primarily impact the thyroid gland by decreasing its ability to make thyroid hormone, disrupting thyroid hormones once they are made, and causing thyroid hormones to be removed from the body faster. If your metabolism is a large jumbo jetliner, the thyroid gland is one of the engines. POPs appear to work in part by blowing out the thyroid engine.
The symptoms may relate to fluid loss and polyuria, but the course may also be insidious. Diabetic animals are more prone to infections. The long-term complications recognized in humans are much rarer in animals. The principles of treatment (weight loss, oral antidiabetics, subcutaneous insulin) and management of emergencies (e.g. ketoacidosis) are similar to those in humans.[123]

The most common side effects of anti-hypertensive medications include hypotension (low blood pressure) and dizziness. These effects are the result of the excessive lowering of blood pressure, and they can be alleviated if your doctor adjusts your medication dose. Each drug and medication category also has its own unique side effects, which you should familiarize yourself with when you begin taking the medication (check patient information provided by your pharmacy, or ask the pharmacist herself).
Staphylococcus or staph is a group of bacteria that can cause a multitude of diseases. Staph infections can cause illness directly by infection or indirectly by the toxins they produce. Symptoms and signs of a staph infection include redness, swelling, pain, and drainage of pus. Minor skin infections are treated with an antibiotic ointment, while more serious infections are treated with intravenous antibiotics.
People who have metabolic syndrome typically have apple-shaped bodies, meaning they have larger waists and carry a lot of weight around their abdomens. It's thought that having a pear-shaped body — that is, carrying more of your weight around your hips and having a narrower waist — doesn't increase your risk of diabetes, heart disease and other complications of metabolic syndrome.

In most people, high blood pressure rarely causes any signs or symptoms.  It's possible to have it for many years without realizing it. Often, it only becomes apparent during a routine health checkup. Rarely, even when levels are life-threatening, high blood pressure may cause only a few symptoms, such as headaches, dizziness, or frequent nosebleeds.
Diabetes mellitus is classified into four broad categories: type 1, type 2, gestational diabetes, and "other specific types".[11] The "other specific types" are a collection of a few dozen individual causes.[11] Diabetes is a more variable disease than once thought and people may have combinations of forms.[37] The term "diabetes", without qualification, usually refers to diabetes mellitus.
Modern understanding of the cardiovascular system began with the work of physician William Harvey (1578–1657), who described the circulation of blood in his book "De motu cordis". The English clergyman Stephen Hales made the first published measurement of blood pressure in 1733.[152][153] However, hypertension as a clinical entity came into its own with the invention of the cuff-based sphygmomanometer by Scipione Riva-Rocci in 1896.[154] This allowed easy measurement of systolic pressure in the clinic. In 1905, Nikolai Korotkoff improved the technique by describing the Korotkoff sounds that are heard when the artery is ausculated with a stethoscope while the sphygmomanometer cuff is deflated.[153] This permitted systolic and diastolic pressure to be measured.
I think it's better to look at total work than just reps in a given set, as not all drills are created equal.  For example, if you do a barbell complex consisting of five snatches, five cleans, five front squats, five barbell rows, and five deadlifts, you've done a ton more work than if you just did 25 medicine ball throws.  The loading capabilities are greater with the barbell complex, and the bar travels over a greater distance.  Since work equals force times distance, it's a more powerful stimulus than the medicine ball throws.

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.


The value of routine screening for hypertension in children over the age of 3 years is debated.[90][91] In 2004 the National High Blood Pressure Education Program recommended that children aged 3 years and older have blood pressure measurement at least once at every health care visit[89] and the National Heart, Lung, and Blood Institute and American Academy of Pediatrics made a similar recommendation.[92] However, the American Academy of Family Physicians[93] supports the view of the U.S. Preventive Services Task Force that the available evidence is insufficient to determine the balance of benefits and harms of screening for hypertension in children and adolescents who do not have symptoms.[94]
There is debate regarding whether obesity or insulin resistance is the cause of the metabolic syndrome or if they are consequences of a more far-reaching metabolic derangement. A number of markers of systemic inflammation, including C-reactive protein, are often increased, as are fibrinogen, interleukin 6, tumor necrosis factor-alpha (TNF-α), and others. Some have pointed to a variety of causes, including increased uric acid levels caused by dietary fructose.[18][19][20]
These diabetes complications are related to blood vessel diseases and are generally classified into small vessel disease, such as those involving the eyes, kidneys and nerves (microvascular disease), and large vessel disease involving the heart and blood vessels (macrovascular disease). Diabetes accelerates hardening of the arteries (atherosclerosis) of the larger blood vessels, leading to coronary heart disease (angina or heart attack), strokes, and pain in the lower extremities because of lack of blood supply (claudication).
This explains why my attempts at a low fat, high protein, high carb diet left me gaining weight all while eating 1000 calories per day! Those 1000 calories were simply fueling my brain and then getting shuttled into my fat cells. If you are not insulin resistant, then this diet may be just the thing you need to shed some short term pounds (although I never recommend a 1000 calorie diet!- more on that later), but to me it caused metabolic chaos.

How many calories should I eat a day? A calorie is an amount of energy that a particular food provides. Consuming more calories than needed will result in weight gain, consuming too few will result in weight loss. How many calories a person should eat each day depends on a variety of factors, such as age, size, sex, activity levels, and general health. Read now

Hypertensive urgencies, where asymptomatic blood pressure is more than 180/110 mm Hg, without organ damage, and emergencies, where organs are damaged and blood pressure measurements can be higher than 180/120 mm Hg, must be treated immediately. They may require hospitalization so that intravenous medications can be given and monitored because, if untreated, they can quickly result in organ damage.
Patients with metabolic syndrome can have several disorders of coagulation that make it easier for blood clots to form within blood vessels. These blood clots are often a precipitating factor in developing heart attacks. Patients with metabolic syndrome should generally be placed on daily aspirin therapy to help prevent such clotting events. You should speak to a doctor, of course, before starting any new medication regimen.
Diabetes mellitus (DM), commonly referred to as diabetes, is a group of metabolic disorders in which there are high blood sugar levels over a prolonged period.[10] Symptoms of high blood sugar include frequent urination, increased thirst, and increased hunger.[2] If left untreated, diabetes can cause many complications.[2] Acute complications can include diabetic ketoacidosis, hyperosmolar hyperglycemic state, or death.[3] Serious long-term complications include cardiovascular disease, stroke, chronic kidney disease, foot ulcers, and damage to the eyes.[2]
Hypertension is a worldwide epidemic; accordingly, its epidemiology has been well studied. Data from National Health and Nutrition Examination Survey (NHANES) spanning 2011-2014 in the United States found that in the population aged 20 years or older, an estimated 86 million adults had hypertension, with a prevalence of 34%. [1] Hypertension affects US men and women nearly equally, affecting an estimated 40.8 million men and 44.9 million women. [1]
Great article, Roman. I bought LWF2 as soon as I saw that it was released. Typically, sequels are not as good as the first, but I knew Jen's would be the exception and she did not let me down! :) I have seen others ask about your manual if we have already invested in LWF2. How should we go about this? Shall we send you the order number or will it be uploaded to the LWF2 member site in the download section? Cheers and thanks for such epic content!
Exposure to certain viral infections (mumps and Coxsackie viruses) or other environmental toxins may serve to trigger abnormal antibody responses that cause damage to the pancreas cells where insulin is made. Some of the antibodies seen in type 1 diabetes include anti-islet cell antibodies, anti-insulin antibodies and anti-glutamic decarboxylase antibodies. These antibodies can be detected in the majority of patients, and may help determine which individuals are at risk for developing type 1 diabetes.
To measure your blood pressure, a specialist places an inflatable cuff around your arm and measures your blood pressure using a pressure-measuring gauge. A blood pressure reading, as shown in the blood pressure monitor in the image, measures the pressure in your arteries when your heart beats (systolic pressure) in the first number, and the pressure in your arteries between heartbeats (diastolic pressure) in the second number.

Insulin resistance. Insulin is a hormone that helps your body use glucose -- a simple sugar made from the food you eat -- as energy. In people with insulin resistance, the insulin doesn't work as well, so your body keeps making more and more of it to cope with the rising level of glucose. Eventually, this can lead to diabetes. Insulin resistance is closely connected to having excess weight in the belly.
The distribution of adipose tissue appears to affect its role in metabolic syndrome. Fat that is visceral or intra-abdominal correlates with inflammation, whereas subcutaneous fat does not. There are a number of potential explanations for this, including experimental observations that omental fat is more resistant to insulin and may result in a higher concentration of toxic free fatty acids in the portal circulation.

 Even the low-fat craze that kicked off in the late 1970s–which was based on the intuitively appealing but incorrect notion that eating fat will make you fat–depended on the calorie-counting model of weight loss. (Since fatty foods are more calorie-dense than, say, plants, logic suggests that if you eat less of them, you will consume fewer calories overall, and then you’ll lose weight.)

Because metabolic syndrome and insulin resistance are closely tied, many healthcare providers believe that insulin resistance may be a cause of metabolic syndrome. But they have not found a direct link between the two conditions. Others believe that hormone changes caused by chronic stress lead to abdominal obesity, insulin resistance, and higher blood lipids (triglycerides and cholesterol).
Fortunately, since peaking in 2001-2002, the overall prevalence of metabolic syndrome in the United States has fallen, primarily due to decreases in the prevalences of hypertriglyceridemia and hypertension—and in spite of increases in the prevalences of hyperglycemia and obesity/waist circumference. [27]  Data from the 2009-2010 National Health and Nutrition Examination Survey (NHANES) showed that the age-adjusted prevalence of metabolic syndrome had fallen to approximately 24% in men and 22% in women. [28]
In the US, 84.1 million adults—more than 1 in 3—have prediabetes, and 90% of them don’t know they have it. Prediabetes is a serious health condition where blood sugar levels are higher than normal, but not high enough yet to be diagnosed as diabetes. Prediabetes increases your risk for type 2 diabetes, heart disease, and stroke. But through the CDC-led National Diabetes Prevention Program, you can learn practical, real-life changes that can cut your risk for developing type 2 diabetes by as much as 58% (71% if you’re 60 or older).
