Most of overweight and obese individuals that i see here in Indonesia do not do proper regular exercise. Some of them jog or walk for about 1 hour once a week. Others just sit there feeling tired.

Ok, they also have interhash (hiking) once in a month, which is a very good exercise. They just don't have enough of it.

Although there are many factors that contribute to overweight and obesity, i think, exercise is the first best shot. No matter of your weight, thin, slim, overweight or obese, we should be exercising regularly, properly. So let's go folks !!

While high body fat percentage usually accompanies a high BMI, it's not always the case. Just the other day I took anthros on a woman who was visibly thin at 5'3", 112 pounds, and had a BMI of 19.9, but she also had a body fat of 34%. Someone can be thin, but still over-fat. They only mentioned body fat in the article, so while we can assume that most of these individuals were overweight or obese, we have no way of knowing for sure.

Just a thought.

You are all right about the calcium deficient dietary habits that are routine, but to absorb calcium from the source there must be adequate magnesim and vitamin D. Magnesium is a clear dieatary thing with the best sources found in dark greens, nuts and bran, but the vitamin D is another issue. We make it in our skin in the presence of sunlight, but how much a person can make depends on many conditions. Vitamin D can only be made by the most direct sun rays (UVB), so latitude is a factor, pigmentation is a factor but so is age (elderly skin does not make vitamin D as well as younger skin). Obesity has also been found to be a factor. Obese people, even accounting for pigmentation, latitude and sun exposure have been found to have lower vitamin D levels than the non obese. You need adequate vitamin D to promote osteoblast (bone formation) activity.

Just how many fat people have you seen with osteoporosis??? every person I have ever seen with this debilitating disease has been thin or very moderately overweight. I have NEVER seen an obese person with a hump back! I find much of this "evidence" to not fit in with what I obseve. I shope weekly (and sometimes several times a week) and all the hump backs are very skinny women or men (one poor man is constantly in a leaning over position where his face is down even with his stomach as he is so humpbacked!!!!

I am sure obesity has its own issues, but i fail to see bone problems as a major issue. I do believe that most Americans do not get enough calcium in their diets due to improper eating habits and improper food processing. However, there are many ways we can eradicate this problem by educating people on the need to supplement the diet with a good source of natural calcium so that we do not have a nation with bone problems. Besides osteoporosis, a lack of calcium causes over 147 different diseases including arthritis, Bell's palsy, kidney stones, and a litany of other problems.

I believe that better nutrition is the key to better health, and you can bet your bottom dollar that public schools are NOT the answer to this dilemma. They can't even serve decent lunches.

The government is NOT the answer either since we live in a FREE republic, which means we should NOT live under the oppression of government interference in our private lives.

Let's talk science, not junk science or physcians & nutritionists parroting wrong information about weight loss/obesity. As usual we have been lied to for profit. Since I only have 2,000 characters, I'll simplfy. Harper's Illustrated Biochemistry 26th edition states - "carbohydrates must be eaten for fat to be stored. Glycerol-3-phosphate must be supplied from [dietary] glucose [carbohydates] via glycolysis [breakdown of sugar]. What this means, is that glycerol-3-phosphate only comes from carbohydates consumption and excess bodyfat can't be stored without it". The medical textbook "Scientific Foundation of Bio-Chemistry in Clinical Practice" states "just 1% of your pancreas is capable of treating all that sugar [carbohydrates]. That's 1 tsp in the blood-we are over-taxing our pancreas. The remaining 99% is for natural fats & protein. The hormone insulin is also for fat storage, insulin does not respond to natural fats & protein. "Textbook of Medical Physiology" states, Insulin causes fat to deposit. When insulin is not available, fat storage is blocked." The saying "fat burns in the flame of a carbohydrate is completely false. The body does not recognize simple vs complex carbohydrates, only that it is a carbohydrate. less insulin=less fat. Medical textbook, "Basic Medical Biochemistry" states, "the body oxidizes [burns as fuel] more fatty acids each day than any other fuel. Fatty acids [fats] are the major fuel in humans. Carbohydates are NOT the body's preferred energy source. Two times, 1893 & 1961 the "Calorie Theory" has been disproven. [Calories in=calories dispensed determines weight loss or gain is wrong] Humans are not heat engines, we are chemical plants. No one is eating calories, we eat food for energy, for structure, making muscle, hormones, enzymes, antibodies and bones. Fireplaces are an example of a heat engine that burns all it fuel for energy. If we were heat engines we would have varying temperatures versus a gradient 98.6F

Hi PepperR23: You are correct: soy can be another reason, if one is sensitive to it (and it is on the list of the top foods that people are sensitive to) or if one has a tendency towards low thyroid because soy is a goitrogen. there are many possible reasons for weight loss resistance. My point was to say that labeling the obese as 'fat, lazy, too attached to food and not willing to exercise" is mean and most often very wrong. Looking at thyroid, possible food sensitivities, exposure to toxicity, hormonal balance (including leptin, cortisol and insulin), stress levels, sleep issues, possible hidden infections (there actually are "fat bugs") and of course diet and exercise are ALL parts of the total picture in helping someone to lose weight if they need to.

Giving up sugar will also decrease your calcium excretion (sugar in=calcium out). Read "Lick The Sugar Habit" by Dr. Nancy Appleton, PhD. She also recommends calcium supplementation in the proper ratio to phosphorus. Too much calcium without the proper Ph ratio will cause "toxic calcium" in the joints and heart. I gave up my addiction to sugar after reading her book. I lost 10 lbs and I feel great...I was slim to begin with. I will never go back on sugar :)

There is clearly an issue of muticollinearity here, as some have suggested. Do obese people get less weight bearing exercise? Did the study correct for this?

And what about the very thin people, those with eating disorders, or elderly women with loss of lean body mass? This was certainly my mother's case. She weighed eighty pounds when she died (at age 88), and she has bone density 30% of normal.

I am a nutritionist and have worked with obese people. These people are active, want to be healthy and do everything they have been told to do to lose weight. And there lies the problem. They have been given bad advice. Obesity is a much more complex issue then "calories in, calories out". For example, I am seeing an incredible rise in the amount of hypothyroidism (low thyroid) out there, but in most cases due to autoimmune thyroiditis (Hashimoto's disease) where the body is attacking the thyroid. These people have a terrible time losing weight. But there often is a strong dietary connection - in this case gluten intolerance. Once they get off gluten (and are strict about this) the thyroid antibodies often drastically come down. Doctors can check for thyroid antibodies. Another probem associated with weight loss resistance is high blood insulin levels (as Dr. Mercola has said). With this issue, you could be running hard on a treadmill for hours and lose nothing. High blood insulin levels encourage the body to hang onto fat. A third issue is toxicity. Fat soluble toxins (like those from petrochemicals) are stashed into fat cells to protect the vulnerable parts of the body. You would not want to go on a fast fat burning program if this is your problem as you could unleash a lot of toxicity into the bloodstream too quickly. Identifying an individual's unique biochemical challenges and working at this level is the best way to lose weight (if needed) and to be healthy.

I thought that keeping leptin low is the key, because when it is high, the body burns carbs and protein for fuel. If it is low, then fat is burned. Am I incorrect? Plus, when the body is in the carb/protein burning mode and you starve yourself, the body looks inside for protein to burn, and that includes the matrix of the bones, weakening them....osteoporosis? Anyway, according to Rosedale, you want leptin levels low, so the signal to burn fat will occur...so again, it's back to eat more veggies, small meat portions, etc.

I think there is a lot of discrimination against fat people like there still is to a lesser extent toward fats in the diet.

You still have lots of health care people touting a "low fat" diet when anyone who has actually studied the subject knows better. If you want to see bones deteriorating, look at studies of young women and older women who are bulemic or anorexic, even borderline cases. Many years of starving themselves keeps many nutrients from reaching healthy bones, which begin to look like swiss cheese as they get older. The "experts" have to have something to blame for poor health care and big pharma needing to make giant profits, while ignoring all the sugars and high glycemic starches going into foods these days. So let's all blame the fatties.

I wish things were that simple and for some eating right and exercise may be all they need but I am conviced there is more to it. Ex: my mom, age 73, has always and still is extremely active, eats right, and exercises. She is not over weight by no means and has weak bones. She looks amazing by the way, and takes no medication, so taking care of herself pays off in many respects but still has bad bones.

thank you michael, that was my exact thought. there are many heavy and obese people who are very

active either through physical demanding jobs or hobbies such as gardening or love of walking.

i would venture to say that people with this type of life style are either excluded intentionally or ignored from many of these studies. and if so, they i have to wonder why.

Its not rocket science folks.... If all the 'bad' food such as artificial sugar, soft drinks, refined sugar, flour, table salt, coffee plus cigarettes and liquor is highly acidic then the body has to pull calcium from somewhere to bring the PH of the blood back to a normal reading just to keep that person alive! Most obvious place to get that calcium... teeth and bones.

"The exact mechanisms by which excess fat hinders bone strength are unclear."
I think that majority of obese people don't do hard work for living. Physical activity makes bones and muscles stronger.
Lack of physical activity leads to weakness in both bones and muscles.
I bet a dollar that porky carpenters or sumo restlers don't have weak bones.
Is it diffucult to understand?
