Lisa Simonson wrote in the Livestrong article, What Are Good & Bad Healthy Lifestyle Choices?
Everyone makes both good and bad lifestyle choices. You may make the choices you do because of learned habits, stress, exhaustion and even timeliness. To live a healthy lifestyle you need to have a nutrient-rich diet, moderate exercise each week, get enough rest and avoid products that can lead to unhealthy habits…. https://www.livestrong.com/article/381713-what-are-good-bad-healthy-lifestyle-choices/

Science Daily reported in Digital device overload linked to obesity risk:
If your attention gets diverted in different directions by smartphones and other digital devices, take note: Media multitasking has now been linked to obesity.
New research from Rice University indicates that mindless switching between digital devices is associated with increased susceptibility to food temptations and lack of self-control, which may result in weight gain.
“Increased exposure to phones, tablets and other portable devices has been one of the most significant changes to our environments in the past few decades, and this occurred during a period in which obesity rates also climbed in many places,” said Richard Lopez, a postdoctoral research fellow at Rice and the study’s lead author. “So, we wanted to conduct this research to determine whether links exists between obesity and abuse of digital devices — as captured by people’s tendency to engage in media multitasking….”

Science Daily reported in Study finds dopamine, biological clock link to snacking, overeating and obesity:
During the years 1976 through 1980, 15% of U.S. adults were obese. Today, about 40% of adults are obese. Another 33% are overweight.
Coinciding with this increase in weight are ever-rising rates of heart disease, diabetes, cancer and health complications caused by obesity, such as hypertension. Even Alzheimer’s disease may be partly attributable to obesity and physical inactivity.
“The diet in the U.S. and other nations has changed dramatically in the last 50 years or so, with highly processed foods readily and cheaply available at any time of the day or night,” Ali Güler, a professor of biology at the University of Virginia, said. “Many of these foods are high in sugars, carbohydrates and calories, which makes for an unhealthy diet when consumed regularly over many years.”
In a study published Thursday in the journal Current Biology, Güler and his colleagues demonstrate that the pleasure center of the brain that produces the chemical dopamine, and the brain’s separate biological clock that regulates daily physiological rhythms, are linked, and that high-calorie foods — which bring pleasure — disrupt normal feeding schedules, resulting in overconsumption. Using mice as study models, the researchers mimicked the 24/7 availability of a high-fat diet, and showed that anytime snacking eventually results in obesity and related health problems.
Güler’s team found that mice fed a diet comparable to a wild diet in calories and fats maintained normal eating and exercise schedules and proper weight. But mice fed high-calorie diets laden with fats and sugars began “snacking” at all hours and became obese.
Additionally, so-called “knockout” mice that had their dopamine signaling disrupted — meaning they didn’t seek the rewarding pleasure of the high-fat diet — maintained a normal eating schedule and did not become obese, even when presented with the 24/7 availability of high-calorie feeds.
“We’ve shown that dopamine signaling in the brain governs circadian biology and leads to consumption of energy-dense foods between meals and during odd hours,” Güler said.
Other studies have shown, Güler said, that when mice feed on high-fat foods between meals or during what should be normal resting hours, the excess calories are stored as fat much more readily than the same number of calories consumed only during normal feeding periods. This eventually results in obesity and obesity-related diseases, such as diabetes.
Speaking of the modern human diet, Güler said, “The calories of a full meal may now be packed into a small volume, such as a brownie or a super-size soda. It is very easy for people to over-consume calories and gain excessive weight, often resulting in obesity and a lifetime of related health problems.
“Half of the diseases that affect humans are worsened by obesity. And this results in the need for more medical care and higher health care costs for individuals, and society.”
Güler said the human body, through thousands of years of evolution, is hard-wired to consume as much food as possible as long as it’s available. He said this comes from a long earlier history when people hunted or gathered food and had brief periods of plenty, such as after a kill, and then potentially lengthy periods of famine. Humans also were potential prey to large animals and so actively sought food during the day, and sheltered and rested at night.
“We evolved under pressures we no longer have,” Güler said. “It is natural for our bodies as organisms to want to consume as much as possible, to store fat, because the body doesn’t know when the next meal is coming…. https://www.sciencedaily.com/releases/2020/01/200103111717.htm

He said this comes from a long earlier history when people hunted or gathered food and had brief periods of plenty, such as after a kill, and then potentially lengthy periods of famine. Humans also were potential prey to large animals and so actively sought food during the day, and sheltered and rested at night.
“We evolved under pressures we no longer have,” Güler said. “It is natural for our bodies as organisms to want to consume as much as possible, to store fat, because the body doesn’t know when the next meal is coming.
“But, of course, food is now abundant, and our next meal is as close as the kitchen, or the nearest fast-food drive-through, or right here on our desk. Often, these foods are high in fats, sugars, and therefore calories, and that’s why they taste good. It’s easy to overconsume, and, over time, this takes a toll on our health.”
Additionally, Güler said, prior to the advent of our electricity-powered society, people started the day at dawn, worked all day, often doing manual labor, and then went to sleep with the setting of the sun. Human activity, therefore, was synchronized to day and night. Today, we are working, playing, staying connected—and eating—day and night. This, Guler said, affects our body clocks, which were evolved to operate on a sleep-wake cycle timed to daytime activity, moderate eating and nighttime rest.
“This lights-on-all-the-time, eat-at-any-time lifestyle recasts eating patterns and affects how the body utilizes energy,” he said. “It alters metabolism—as our study shows—and leads to obesity, which causes disease. We’re learning that when we eat is just as important as how much we eat. A calorie is not just a calorie. Calories consumed between meals or at odd hours become stored as fat, and that is the recipe for poor health.”

In other words, much of the obesity problem is due to personal life style choices and the question is whether government can or should regulate those choices.
Personal Responsibility:
There is only one person responsible for your life and the vocation you have chosen. That person is the one you see in the mirror in the morning when you wake up. Don’t blame God, your boss, your parents, your former teachers, your coach, your co-workers or your dog. You and only you are responsible for your work life and what you have achieved. The sooner you accept this notion, the sooner you will begin to make changes that lead to a happier and more productive life and career. http://www.corethemes.com/coreconcepts/
It’s all about ME unless I have to take responsibility for ME. The same brilliant minds who think the government can substitute for family have fostered a single parenthood rate of 70% in the African-American community and about 50% for the population as a whole. Given the child abuse and foster care numbers, this plan hasn’t worked well. Sometimes folks have to be responsible for their choices.
