Many people think that drinking diet soda instead of regular soda will help them lose weight or at least control weight gain. However, studies show that calories from food consumed cause weight gain in people who drink diet soda.

Some people believe that replacing their consumption of sugar-sweetened beverages with that of artificially sweetened drinks helps them lose weight. These artificially sweetened beverages are often called diet soda because they contain no calories in spite of their sweet taste.

Sugary Beverages and Body Weight

Just a few years ago, scientists conducted a national survey to study the trends on the consumption of sugar-sweetened beverages (SSBs) among US adults. They found that in recent decades, there has been a significant rise in the consumption of sugary beverages, which was highest among young adults, especially among black individuals. They also noted that this increase in SSB consumption occurred in people who are of greatest risk for obesity and diabetes. They also observed that although obese and overweight individuals who wanted to lose weight were less likely to drink these beverages, they still drank them in large amounts.

It is interesting to note that in recent decades, the increase in consumption of calories from various types of beverages has paralleled the rise of obesity rates.

Researchers at the Johns Hopkins Bloomberg School of Public Health studied the effects of reducing the intake of different types of beverages on changes in body weight for a period of six to 18 months. These beverages included SSBs (regular soda, fruit drinks, etc), diet drinks, milk products (whole milk, skim milk, 2% reduced-fat, and1% low-fat milk), 100% fruit or vegetable juice, coffee, tea and alcoholic beverages. They found that people who reduced their intake of SSBs were the only ones who lost a significant amount of weight over time.

Is Drinking Diet Soda Effective for Weight Loss?

Observations from various studies linking the consumption of sugary beverages to obesity and overweight has led some people to believe that turning to artificially-sweetened beverages such as diet soda, which has zero calories, can help people lose weight. It is a fact that the consumption of diet beverages has skyrocketed and is considered by some as a strategy to control weight. However, studies evaluating the effects of diet soda and other beverages on weight control have shown conflicting results.

In 2005, researchers at the University of Texas Health Science Center compared the effects of drinking regular soda and diet soda on weight change in more than 1500 participants whom they observed for seven to eight years. They reported that those who regularly consumed diet beverages had the greatest risk of gaining weight, citing that there was more than 40% increased risk of gaining weight for every bottle or can consumed daily. However, the authors explained that diet beverages were not necessarily the cause of obesity or overweight, but the total amount of calories one consumed in their daily diet.

In fact, a more recent survey by researchers at the Johns Hopkins Bloomberg School of Public Health involving about 24,000 participants revealed that people of healthy weight who drank diet soda or other beverages consumed fewer calories from food in their daily diet than people who consumed sugary beverages.

On the other hand, overweight or obese individuals who took diet drinks consumed more calories from food in their diet than those who preferred sugary beverages.
