What Diet Soda Does to Belly Fat

Here is an nutritional article that is very relevant. Here on the reservation we consume more soda per capita than any other population group. There is a variety of reasons for this. Not the least of which is that safe, reliable sources of water is a relatively new luxury here. Combine that with the lack of electricity and therefore, refrigeration, it only makes sense that canned drinks became popular. As bad as sodas are, I have had several elders tell me that they are probably better than drinking the water in some areas. Likely there is some truth to that. As the years progressed and diabetes became epidemic, curbing the appetite for soda has become a priority with health care providers. However, in an effort to do so, I have seen many well meaning health professionals encouraging people to substitute diet sodas instead. On the surface this may seem like a good idea. After all, they are sugar free and sugar is the enemy,.....right? As we can read below, diet drinks are not a good choice either. They bring their own truckload of problems. So, what should we be drinking? I love water. 8 or more glasses a day is a great plan. Milk is also a good choice although many natives are lactose intolerant. Fruit juices are not a whole lot better than sodas. Homemade fruit smoothies made in a blender are also great. Add some protein and it's even better. Learn to drink water and eat good food for flavor.

A new study published in the Journal of the American Geriatrics Society found that people who drank diet soda gained almost triple the abdominal fat over nine years as those who didn’t drink diet soda. The study analyzed data from 749 people ages 65 and older who were asked, every couple of years, how many cans of soda they drank a day, and how many of those sodas were diet or regular.

Those answers ended up being extremely predictive of abdominal-fat gain, even after the researchers adjusted for factors like diabetes, smoking and levels of physical activity. People who didn’t drink diet soda gained about 0.8 in. around their waists over the study period, but people who drank diet soda daily gained 3.2 in. Those who fell in the middle — occasional drinkers of diet soda — gained about 1.8 in.

That change in waist circumference is especially concerning because it highlights an unfortunate truth about weight distribution: the belly is a bad place for extra pounds. The kind that pads the abs from the inside, called visceral fat, is associated with increased cardiovascular disease, inflammation and Type 2 diabetes.

These results, which the study authors call “striking,” add to the growing body of evidence that no- and low-calorie sweeteners may come with health concerns. Though scientists are still puzzling through the mechanisms by which diet soda seems to have the unintended consequence of weight gain, they have some ideas. Sugar-free sodas contain substances that sweeten up soda at 200-600 times the sweetness of sugar.

"Regular sugar has caloric consequences," says the study's senior author Dr. Helen Hazuda, professor of medicine at the University of Texas Health Science Center at San Antonio. And one of those is that it triggers satiety — a sense of fullness or satisfaction. "Your body is used to knowing that a sweet taste means you are ingesting energy in the form of calories that, if you don’t burn them off, is going to convert to fat," she says. Artificial sweeteners, however, confuse our bodies and weaken the link in our brains between sweetness and calories. That, Hazuda says, can lead to weight gain and cravings for sweeter and sweeter treats.
There may be something else at work. A recent study in mice showed that artificial sweeteners actually changed the gut bacteria of mice in ways that made them vulnerable to insulin resistance and glucose intolerance — both of which can lead to weight gain. And other mice research suggests that artificial sweeteners are associated with a drop in the appetite-regulating hormone leptin, Hazuda says. Leptin is the hormone that inhibits hunger.

The Calorie Control Council, an association that represents the reduced-calorie food and beverage industry — including alternative sweeteners — disagreed with the study's findings. "The use of low-calorie sweeteners (LCSs) in weight management has been shown to be beneficial," the group said in a statement. "While approaches to treat obesity in older individuals is controversial, diet modifications can be a successful part of a weight-management program for older adults."

Researchers in the new study found that belly-fat gain was most pronounced in people who were already overweight. "People who are already at cardiometabolic risk because they have higher BMIs are really in double or triple jeopardy," Hazuda says. "When they think they’re doing something good by drinking artificially sweetened beverages, it’s actually totally counterproductive."

Water is a great choice!
