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!

When you go on a diet set your protein intake higher. Studies have shown that a higher protein diet, one that exceeds the RDA of .8g/kg body weight, helps offset the decline in metabolic rate that occurs with dieting. At Metabolic Effect, we set the protein level to 40% of total calories during fat reducing stages (i.e. 30:40:30 carbs:protein:fat). Another way to look at this is to make sure you are getting at least 1g of protein per pound of body weight (if you want to try to gain muscle) or 1g per pound of muscle mass (if you are trying to just maintain muscle).

Undiagnosed metabolic conditions are rampant in today’s society because medical providers are simply not testing for them.  Most commonly medical providers are solely looking and testing for diseases they can treat with medications or surgery.  This leaves a large hole in healthcare for those that are struggling with their weight and health, but do not need drugs or surgery.  We call this the medical black hole.  Ultimately, because of the medical black hole millions of americans are walking around every day with hidden metabolic disorders that are allowed to spread and worsen over time as metabolism in an interconnected web.  One area affects all other areas.

After reading a recent Time article entitled “The Weight loss trap” I quite literally jumped off of my office chair, frustrated, angry and delighted. (I also lit up my husband’s phone with a thousand messages). I am so over misinformation in the weight loss space, but even more, it kills me that people are made to feel out of control and hopeless in their own bodies. Why delighted? Well, I was not quite ready to announce my upcoming book but I just could not give up this opportunity to share with you all of the reasons why Time has great points, but doesn’t tell the whole story. You can finally overcome weight loss resistance!
A blood pressure reading measures both the systolic and diastolic forces, with the systolic pressure listed first. The numbers show your pressure in units of millimeters of mercury (mm Hg)—how high the pressure inside your arteries would be able to raise a column of mercury. For example, a reading of 120/80 mm Hg means a systolic pressure of 120 mm Hg and diastolic pressure of 80 mm Hg.
When there is excess glucose present in the blood, as with type 2 diabetes, the kidneys react by flushing it out of the blood and into the urine. This results in more urine production and the need to urinate more frequently, as well as an increased risk of urinary tract infections (UTIs) in men and women. People with type 2 diabetes are twice as likely to get a UTI as people without the disease, and the risk is higher in women than in men.
As of 2016, 422 million people have diabetes worldwide,[101] up from an estimated 382 million people in 2013[17] and from 108 million in 1980.[101] Accounting for the shifting age structure of the global population, the prevalence of diabetes is 8.5% among adults, nearly double the rate of 4.7% in 1980.[101] Type 2 makes up about 90% of the cases.[16][18] Some data indicate rates are roughly equal in women and men,[18] but male excess in diabetes has been found in many populations with higher type 2 incidence, possibly due to sex-related differences in insulin sensitivity, consequences of obesity and regional body fat deposition, and other contributing factors such as high blood pressure, tobacco smoking, and alcohol intake.[102][103]
The Time article is based on the reality that most people who lose weight, such as those on the Biggest Loser, end up gaining most of that back, if not more. They discuss that weight loss is highly personalized, that what works for one person will not work for another and also that it is not likely that your genetics or your personality type play into your success all that much. They also discuss that despite the fact that researchers know this, no one really knows why.. that is where we differ in opinion!
Blood pressure is the measurement of the pressure or force of blood pushing against blood vessel walls. In hypertension (high blood pressure), the pressure against the blood vessel walls is consistently too high. High blood pressure is often called the “silent killer” because you may not be aware that anything is wrong, but the damage is occurring within your body.

According to the Centers for Disease Control and Prevention, more than 50% of people age 50 and older have high blood pressure. Women are about as likely as men to develop high blood pressure, though this varies somewhat by age. For people younger than age 45, more men than women are affected, while for those age 65 and older, more women than men are affected. Americans of African descent develop high blood pressure more often and at an earlier age than those of European and Hispanic descent.
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.
Just briefly I want to mention something for the more savvy readers out there. Many, who are well versed in metabolism, will immediately point out that if you lose weight, then of course you are going to be burning less calories because you have less body tissue. True. But what research shows, and my clinical experience validates, is that the reduced rate of metabolic output goes far beyond what would be predicted from loss of fat mass or muscle mass.
"Brittle" diabetes, also known as unstable diabetes or labile diabetes, is a term that was traditionally used to describe the dramatic and recurrent swings in glucose levels, often occurring for no apparent reason in insulin-dependent diabetes. This term, however, has no biologic basis and should not be used.[39] Still, type 1 diabetes can be accompanied by irregular and unpredictable high blood sugar levels, frequently with ketosis, and sometimes with serious low blood sugar levels. Other complications include an impaired counterregulatory response to low blood sugar, infection, gastroparesis (which leads to erratic absorption of dietary carbohydrates), and endocrinopathies (e.g., Addison's disease).[39] These phenomena are believed to occur no more frequently than in 1% to 2% of persons with type 1 diabetes.[40]
Not so anymore. Thanks to the rising obesity epidemic in young people, kids and teens are getting these conditions — and they're getting them earlier than ever before. Some estimates say that nearly 1 in 10 teens — and over a third of obese teens — have metabolic syndrome. And a study of 375 second- and third-graders found that 5% had metabolic syndrome and 45% had one or two risk factors for it.

Family or personal history. Your risk increases if you have prediabetes — a precursor to type 2 diabetes — or if a close family member, such as a parent or sibling, has type 2 diabetes. You're also at greater risk if you had gestational diabetes during a previous pregnancy, if you delivered a very large baby or if you had an unexplained stillbirth.

Medicines are available if these changes do not help control your blood pressure within 3 to 6 months. Diuretics help rid your body of water and sodium. ACE inhibitors block the enzyme that raises your blood pressure. Other types of medicines— beta blockers, calcium channel blockers, and other vasodilators—work in different ways, but their overall effect is to help relax and widen your blood vessels and reduce the pressure inside the vessel.

Fruit juices and sugary beverages can make your blood sugar and triglyceride levels soar. Alcoholic beverages may cause hypoglycemia and an initial drop in blood sugar, but those numbers will then climb — especially if you’re consuming mixed cocktails. Water is the best beverage for healthy hydration. And it’s good to know that tea, coffee, skim or low-fat milk, and fruits and vegetables provide water without extra calories, too.
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.
Diabetes mellitus is a chronic disease, for which there is no known cure except in very specific situations.[75] Management concentrates on keeping blood sugar levels as close to normal, without causing low blood sugar. This can usually be accomplished with a healthy diet, exercise, weight loss, and use of appropriate medications (insulin in the case of type 1 diabetes; oral medications, as well as possibly insulin, in type 2 diabetes).
Cortisol reactivity, an index of hypothalamic-pituitary-adrenal function, may be another mechanism by which psychosocial stress is associated with future hypertension. [20] In a prospective sub-study of the Whitehall II cohort, with 3 years follow-up of an occupational cohort in previously healthy patients, investigators reported 15.9% of the patient sample developed hypertension in response to laboratory-induced mental stressors and found an association between cortisol stress reactivity and incident hypertension.
