Health Risks of Obesity

November 28, 2011 By

Nutrition and health science is constantly evolving, and it often seems as if the latest study contradicts earlier ones. It’s hard to know what to believe. But, over the last few decades, a wide array of independent studies has tended to confirm some conclusions about the relationship between excess body fat and associated health risks.

The basic conclusion is that anyone who is considerably overweight is at higher risk for a number of potential health problems. These include various forms of heart condition, high blood pressure, diabetes, colon cancer, liver damage, gallstones and others.

But what is ‘considerably overweight’?

There’s no static, ideal weight for any given individual, though there are various factors that provide a healthy range. One measurement that is a good starting point is BMI (Body Mass Index). To calculate it, just divide your weight (in kg) by your height (in m) squared. The following table is a rough classification:

Under 18.5 = Underweight
Between 18.5 and 24.99 = Normal Weight
Between 25 and 29.99 = Overweight
Between 30 and 34.99 = Obese (Class 1)
Between 35 and 39.99 = Obese (Class 2)
40 and above = Extreme Obesity

For those on the lower end of the BMI scale, health risks are no more (or at most only moderately higher) than for anyone. Genetic and other environmental factors will outweigh any body fat or weight issues. But for those nearer the higher range, there is strong evidence that health risks are higher.

For example, abdominal obesity (having large fat deposits around the stomach and abdomen) is associated with increased risk of cardiovascular disease and insulin resistance syndrome. For women, a waist circumference of 35 inches or more (40+ in men) is an indicator of abdominal obesity. Among other conditions, high blood pressure, high triglycerides and high cholesterol are all common factors associated with that condition.

Narrowing of the arteries, atherosclerosis, contributes to the possibility of a clot which can cause a stroke. Excessive body fat is one factor in producing that condition. At the same time, it plays a part in increased blood pressure (hypertension).

Rapid weight gain, from 10-20 lbs for the average person, increases the odds of developing Type 2 diabetes. Genetic factors are fundamental, but weight gain plays a role, according to most studies. The risk is double that of an individual who has not had a weight gain, when other factors are held constant.

Liver disease, apart from that associated with excessive alcohol consumption, can be caused by insulin resistance. That resistance is much more likely among those who are obese. There are many studies which have correlated BMI with the degree of liver damage. The higher the BMI, the greater the odds of liver trouble.

Gallstones are more likely to form in those who are obese, and may be correlated with a rapid rise in BMI. Sleep apnea (interruption of breathing during sleep) is another condition commonly linked to obesity.

In short, though no single study is definitive, and there are many genetic and other environmental elements, excessive body fat is a substantial factor in health issues. Being overweight is not merely an issue of acceptable appearance, it’s a health risk.

Fluids and Weight Loss

September 14, 2011 By

Diets, especially those that focus on weight loss, often concentrate on what to eat. But fluids are a major part of any healthy, balanced diet as well. Runners know this well, but the same guidelines apply to anyone interested in optimal health.

About 60% of the human body is water, muscle tissue almost 70%. An enormous range of biochemical reactions inside cells and out require water. Add these facts together and it’s clear that water is a must. No surprise, there. But what might be is how easy it is to have a deficit.

Effects of Dehydration

Lack of proper hydration can have far worse effects than merely feeling thirsty. Headache, fatigue and dizziness are common signs. Heat stroke is serious, potentially fatal – and dehydration is one of the major factors that lead to it.

Nor is it quite good enough to merely wait until you are thirsty to address your fluid need. Elevated internal body temperature, high heart rate and poor motor performance set in when your body has experienced only a 3% weight loss from water deprivation.

In a cool environment, even when you are at rest, your body will lose about 2-3 liters in a day. If you’re active, the number rises to between 3-6 liters. On a warm day, during vigorous activity, the number can be as high as 10 liters. That’s about 3 gallons of water in one day.

How Much Should You Consume and When?

It’s preferable to hydrate in advance. According to the American College of Sports Medicine, that amounts to about 17 ounces (500 ml) every 2 hours for 24 hours prior to any vigorous workout. Another 7-10 ounces (about 200-300 ml) every 20 minutes during exercise is also recommended.

What About Sports Drinks?

Some sports drinks are the perfect form of fluid intake. Just drinking water can lead to harmful dilution of the concentrations of sodium, potassium and other minerals in the body. Among other things, those help regulate the heart and nerve signals. A properly balanced sports drink helps maintain the proper concentration.

But many so-called sports drinks are chock full of sugar. A little bit of simple sugar isn’t bad. It can even be beneficial. But a bottle of sports drink that is really just soda without the bubbles isn’t helpful. Keep that type to a minimum.

Fruit juices can be an effective way of getting needed fluid. But keep in mind that drinks with carbs slow the body’s rate of absorption of water. Here too, the amount of sugar needs to be monitored.

Caffeine and Alcohol

Caffeine drinks aren’t necessarily unhealthy. In fact, in moderation, caffeine has been shown to have definite health benefits. But it’s also a diuretic, a substance that increases urine output. Drinking lots of coffee can actually encourage dehydration. Studies in which participants drank about 6 cups per day (642 mg/day) experienced a 3% loss of body water.

Similarly, alcohol in moderate amounts is beneficial. Red wine has antioxidants. Even beer is healthy, since some of the health effects are due to alcohol alone and hops are good for you. But they do tend also to dehydrate. They’re not a substitute for the total water needed daily.

Summary

The body needs several types of nutrients every day, throughout the day: proteins, fats, carbohydrates, vitamins and minerals – and water. Don’t forget the liquid nutrient.

Is the Internet Destroying your Intelligence?

December 9, 2010 By

I can’t focus
I’ve been diagnosed with adult ADD
I can’t sleep at night
I just can’t concentrate anymore
My memory stinks…
These are just a few of the complaints that I hear from my clients daily. What is going on and why do so many people have such a hard time with their minds? We are literally a nation of broken minds.  ADD, depression/Anxiety and memory/focus issues are just the most visible problems.  The average person is functioning at a much lower level then man did in the past.

First we need to make sure that nutrition is up to par before looking elsewhere. But if someone takes vitamins and eats right and gets a decent amount of sleep, what is the story? Is it possible that we are training our brains to focus shallowly? To simply skim the surface? To never delve deeply into researching and reading since we can find any fact we want by using Google? What an amazing tool, but like any other increase in technology there is always a downside.

There are several studies that demonstrate exactly  that. The mind will become patterned by the way it is used.  If you consistently move from channel to channel on the TV or from web site to website on the internet you are training your mind to think shallowly.  You are not spending time thinking through a problem so much as finding someone else who has done it for you on-line.  Rarely does anyone need to spend time in school delving through major amounts of text to find an answer. Instead we jump from idea to idea, concept to concept and maintain a “novelty seeking” mentality to finding the answers we desire. This results in permanent changes in brain function and the size of various parts of the brain. Multi-tasking has been  proven to be bad for the brain.

When we engage in thrill seeking or novelty addicted behavior we grow the part of our mind that responds to pleasure. Soon that part of our mind becomes addicted to the brain chemicals being released and needs more and more to get the same feeling.  Think gambling addictions, sex addicts or substance abuse.  Through using technology in a specific way we are turning technology into an addictive substance that integrates easily into our lives. But the results can be as negative long term as having any other kind of addiction.  Shrinking the prefrontal cortex creates  behavior problems like ADD, depression and Anxiety.

One of the best ways to change this pattern is to increase the size of the prefrontal cortex which is done by increasing blood flow to that part of your brain.  The prefrontal cortex controls executive functions and when you use hypnosis to still the mind or relax the mind into the alpha/theta brainwaves you are supplying nutrition to this part of the brain. You are building mental muscle. Buddhist monks who meditate daily are shown to have a much larger prefrontal cortex than the average person.

So give it a try…take a day off from the Internet.  Watch one show at a time on TV.  Read a non-fiction book instead of just snapping up information on Google. Turn off your “smart phone” .  Stop making calls and texting while driving.  Better yet just take some time to simply “be”. You may actually start feeling smarter, more focused and calm then you can remember feeling in a really long time.

Weight Loss, Why not just stop eating?

August 2, 2010 By

One sure way to lose weight, it might seem, is simply to stop eating for a while. Simple as it sounds, that idea is fraught with potential problems.

The basic weight loss equation certainly remains valid in this case: using more calories than are consumed results in weight loss. If you don’t take in calories by eating, it’s fairly easy to satisfy that equation. Your body burns 70 calories per hour even just sitting idle on the couch.

But while you may be idle, your body’s systems are not.

First of all, the body – deprived of food – will slow down the metabolism and burn calories more slowly. weight loss can be sudden at first, but the rate slows very soon thereafter.

At first, it goes after glycogen stored in the liver and converts it to glucose to burn for energy. That energy is used to power all the body’s activities.

When that is used up (to a degree), the body then begins going after the energy stored in the bonds of certain molecules in fat cells. The process is called ketosis and accounts for why your breath sometimes smells like fingernail polish (made with ketones) after hard exercise.

So far, that all sounds good. You burn calories, reduce body fat and lose weight. Exactly what you wanted. But, unfortunately, this isn’t all the body is doing under these circumstances.

Because of the relatively rapid weight loss/calorie burning from this method of ‘dieting’ the body will experience a ‘rebound’ effect. In other words, it will cause you to crave food like crazy. The food you do eat will cause you to put on more pounds than you lost. The body is compensating for a radical deficit.

At the same time, there are serious health risks to simply starving or a long term fast. Going without food for a few hours or even a day isn’t dangerous, though it can be uncomfortable since you’ll get very hungry. But this method causes a number of carefully balanced nutrients to get out of whack.

It upsets the delicate balance of insulin, sugar and a variety of other essential compounds. Apart from regulating energy levels, they influence hormones that regulate the brain and nervous system.

Concentrations of potassium and sodium get out of balance unless you compensate with sports-style drinks, which can be more difficult to adjust in the absence of food. Those minerals are key to regulating the heartbeat, not to mention being found in every cell of the body and the fluid in between where they participate in an enormous variety of vital tasks.

Fatigue, dizziness and difficulty concentrating are only three of the milder symptoms that will result. Dehydration is likely, since much of the fluid we gain is from food, not just liquid. That can easily lead to heat stroke if the weather is at all warm and you are even a little active.

The kidneys will have a more difficult time filtering properly. They clean waste material from the blood, play a role in regulating blood pressure and stimulate the bone marrow to make red blood cells.

The odds of heart attack are increased, brain function suffers,… the list is endless. Even if the fast is ended long before death (at about 4 weeks), serious physical effects would occur.

Instead of fasting, eat a balanced, healthy diet of limited calories – combined with an age and circumstance-appropriate exercise program and find a way to stay on track.  Motivation is the key to staying with any new kind of life style. Lets not kid ourselves, what permanent weight loss requires is a permanent change in life style.  Hypnotherapy is one of the best ways to create a new habit and get rid of old negative or unhealthy ways of thinking about food.  That is the surest way to lose pounds safely. Your physical health will be in harmony with your mind and your new healthy eating/exercise habits will become part of who you are.
