Surprising factors that may keep you thin
    2018-January-12  08:53    Shenzhen Daily

HAVE you ever wondered why some people seem to stay trim effortlessly, while others struggle with their weight? Sure, genetics and a healthy lifestyle play a large role, but there are other, more surprising correlations that may be helping them stay slim.

1. They live near a gym.

A recent study in the journal Lancet Public Health found that people living within a kilometer of physical activity facilities — including gyms, swimming pools and playing fields — weighed less and had smaller waists than those who didn’t. The difference was greater in women and those with higher incomes.

The study was observational, so it does not prove cause and effect, but it does reinforce the impact of the built environment, including city design, on body weight. Other research has found that more walkable neighborhoods are also associated with lower weight.

The Lancet study also found an effect, albeit weaker, on proximity to fast food restaurants: Study subjects who lived 2 kilometers or farther from a fast food outlet versus within half a kilometer were slimmer, especially women.

2. They fidget a lot.

A review article nearly a decade ago found that people with the highest levels of spontaneous physical activity, including fidgeting, tend to weigh less.

Although fidgeting has a strong genetic and biological component, increasing non-exercise-related physical activity — including walking, standing, cooking and even gardening — can also play a significant role in keeping people trim.

This type of non-exercise activity makes up a significant and modifiable portion of your total daily calorie burning, and it can play an important role in helping you stay lean. It is even more important in our modern environment, filled with labor-saving devices, televisions and technology.

A 2003 study found that the impact of mechanization and labor-saving devices, including dishwashers, washing machines, escalators and cars utilized in driving to work, led to a 111-calorie reduction in daily energy expenditure. Unless this reduction is offset by increased activity, it could lead to significant weight gain over time.

3. They eat spicy food.

If you pay closer attention, you may notice that your naturally slim friends are the ones dousing their meals with extra-spicy hot sauce or eating hot chili peppers regularly. This may not be a coincidence. Observational data show that eating spicier foods is associated with less obesity.

A recent review article summarizes the growing body of research showing that capsaicin, a major bioactive compound present in chili peppers, may play a role in weight control in several ways, including reducing appetite, activating heat-generating and calorie-burning brown fat, increasing the use of fat as fuel and modestly increasing metabolism.

In addition, spicy food seems to keep people healthier. A very large Chinese study found that those who ate spicy food six to seven times per week versus once or less per week were 14 percent less likely to die from any cause. Numerous other spices including cumin, ginger, rosemary, oregano, cinnamon and turmeric may also play a role in helping you stay slim by reducing inflammation, improving your body’s response to insulin and improving the composition of bacteria in your gut.

If you don’t live near an exercise facility or a big fan of spicy food, a healthy lifestyle — including daily exercise, less sedentary behavior, better sleep and a healthful diet — will help keep you lean, regardless of your environment.(SD-Agencies)
