The researchers also looked at the link between inactivity and weight gain, to determine whether it was causative. By studying lean mice that were engineered to have the same defect in the D2 receptor, they found that those mice did not gain weight more readily on a high-fat diet, despite their lack of inactivity, suggesting that weight gain was compounded once the mice start moving less.

“In many cases, willpower is invoked as a way to modify behavior,” Kravitz said. “But if we don’t understand the underlying physical basis for that behavior, it’s difficult to say that willpower alone can solve it.”

US Obesity Problem Is Not Budging, New Data Shows
October 13, 2017 — America's weight problem isn't getting any better, according to new government research.

Overall, obesity figures stayed about the same: About 40 percent of adults are obese and 18.5 percent of children. Those numbers are a slight increase from the last report but the difference is so small that it could have occurred by chance. Worrisome to experts is the rate for children and teenagers, which had hovered around 17 percent for a decade. The 2-to-5 age group had the biggest rise.

The years ahead will show if that's a statistical blip or marks the start of a real trend, said the report's lead author, Dr. Craig Hales of the U.S. Centers for Disease Control and Prevention. The bad news is that the numbers didn't go down, experts say. In recent years, state and national health officials have focused on obesity in kids, who were the target of the national Let's Move campaign launched by former first lady Michelle Obama in 2010.

Two women converse in New York. New government figures released Friday, Oct. 13, 2017 showed small increases that were not considered statistically significant but were seen by some as a cause for concern. The adult obesity rate rose from to about 40 percent, from just shy of 38 percent.

The report released Friday covers 2015 and 2016. "This is quite disappointing. If we were expecting the trends to budge, this is when they would be budging," said Andrew Stokes, a Boston University expert on tracking obesity. The new figures are from an annual government survey with about 5,000 participants. The survey is considered the gold standard for measuring the nation's waistline, because participants are put on a scale to verify their weight.

Obesity means not merely overweight, but seriously overweight, as determined by a calculation called body mass index . Until the early 1980s, only about 1 in 6 adults were obese. The rate climbed dramatically to about 1 in 3 around a decade ago, then seemed to level off for years.

WHO Warns of Child Obesity Epidemic
October 11, 2017 — A study shows there has been a tenfold increase in the number of obese and overweight children and adolescents worldwide in just 40 years.

In one of the biggest epidemiological studies ever undertaken, scientists with the World Health Organization and Imperial College London analyzed height and weight data for 130 million people since 1975, to get their Body Mass Index or BMI. The most dramatic changes have occurred in middle income countries in regions such as East Asia, the Middle East and North Africa, and Latin America. Lead author, Professor Majid Ezzati of Imperial College London is surprised by the speed of change. “Places that a few decades ago, there may have been very little obesity and a fair amount of underweight children, suddenly are bordering on having epidemics.” In higher income countries, rates of childhood obesity have plateaued but remain very high. In that income group, the United States had the highest obesity rates.

Poor policymaking blamed

Researchers say the global obesity epidemic is a result of food marketing and poor policymaking across the globe. “Rather than being an individual’s choice, it’s the hard environments that people choose their foods in healthy foods being priced out of reach, and especially out of reach of the poor, and unhealthy foods being marketed aggressively, together with perhaps not having a safe play area for children, that are leading to weight gain,” says Ezzati. Obesity is an underlying cause of many diseases later in life, including heart disease, stroke, diabetes and some cancers. But Ezzati says it also has a big impact in childhood. “It's associated with a stigma, so psycho-social consequences for the children. There is some evidence that it actually affects the educational outcome for the children.”

Major health challenge

The study also looked at the number of underweight children, which still represents a major health challenge in the poorest parts of the world. India had the highest prevalence of moderately and severely underweight young people across the four decades. “We really need to deal with the two issues at the same time. So we can’t wait to deal with underweight, and then worry about overweight and obesity. The transition happens really fast and they are all different forms of malnutrition,” says Ezzati. Authors of the report are calling for policymakers to find ways to make healthy, nutritious food more available at home and school, especially in poorer families and communities, alongside higher taxes on unhealthy foods.

Inactivity Puts Quarter of Adults' Health at Risk, WHO Says
September 04, 2018 - More than a quarter of the world's adults — 1.4 billion people — exercise too little, putting them at higher risk of cardiovascular disease, type 2 diabetes, dementia and cancers, according to a World Health Organization-led study.

In 2016, around one in three women and one in four men worldwide were not reaching the recommended levels of physical activity to stay healthy — at least 150 minutes of moderate exercise or 75 minutes of vigorous exercise a week. There has been no improvement in global levels of physical activity since 2001, according to the study, which was conducted by WHO researchers and published Tuesday in The Lancet Global Health. The highest rates of lack of exercise in 2016 were in adults in Kuwait, American Samoa, Saudi Arabia and Iraq, where more than half of all adults were not active enough to protect their health.

By comparison, around 40 percent of adults in the United States, 36 percent in Britain and 14 percent in China did too little exercise to stay healthy. "Unlike other major global health risks, levels of insufficient physical activity are not falling worldwide, on average, and over a quarter of all adults are not reaching the recommended levels of physical activity for good health," said Regina Guthold of the WHO, who co-led the research.

Noncommunicable diseases

The WHO says insufficient physical activity is one of the leading risk factors for premature death worldwide. It raises the risk of noncommunicable diseases such as cardiovascular disease, cancer and diabetes. By becoming more active, it says, people can easily achieve benefits such as improve muscular and cardiorespiratory fitness, better bone health, weight control and reduced risk of hypertension, heart disease, stroke, diabetes, depression and various types of cancer.

The study found that levels of low physical activity were more than twice as great in high-income countries compared with poorer nations, and had increased by 5.0 percent in richer countries from 2001 to 2016. In wealthier countries, the researchers said, a transition toward more sedentary jobs as well as sedentary forms of recreation and transport could explain higher levels of inactivity. In less well-off countries, people tend to be more active at work and for transport, they said. They urged governments to take note of these changes and put in place infrastructures that promote walking and cycling for transport and active sports and recreation.

My experience with obesity has been simple: everything is bullshit. All the diet fads, all the stories we tell ourselves, it's all bullshit. It comes down to will and will alone.

If you genuinely want to lose the weight you will through a standard healthy diet and regular exercise. And with Persistence.

If you fail, it will be because you stopped.

Period.

For much of our history on this rock, it was not only near impossible to become obese, but would've been a detriment to survival. We've gone from that, to where even unemployed people can be so obese that they're incapable of doing much of anything, other than eating more food. #Winning?
