DO NOT get diet or low calorie soda, as instead of sugar, it's all chemicals that are even worse.
ever notice everyone drinking diet is fat and not getting thinner because of it?
Correlation doesn't mean causation. Usually people who drink diet soda not only don't account for other problems in their diet, but might feel more motivated to eat more under the pretense that drinking diet soda alone will cause them to lose weight:
Fowler is quick to note that a study of this kind does not prove that diet soda causes obesity. More likely, she says, it shows that something linked to diet soda drinking is also linked to obesity.
"One possible part of the explanation is that people who see they are beginning to gain weight may be more likely to switch from regular to diet soda," Fowler suggests. "But despite their switching, their weight may continue to grow for other reasons. So diet soft-drink use is a marker for overweight and obesity."
Why? Nutrition expert Leslie Bonci, MPH, RD, puts it in a nutshell.
"You have to look at what's on your plate, not just what's in your glass," Bonci tells WebMD.
People often mistake diet drinks for diets, says Bonci, director of sports nutrition at the University of Pittsburgh Medical Center and nutrition consultant to college and professional sports teams and to the Pittsburgh Ballet.
"A lot of people say, 'I am drinking a diet soft drink because that is better for me. But soft drinks by themselves are not the root of America's obesity problem," she says. "You can't go into a fast-food restaurant and say, 'Oh, it's OK because I had diet soda.' If you don't do anything else but switch to a diet soft drink, you are not going to lose weight."
By itself, you literally cannot get fat off of diet soda, its calorie content is far too low relative to the amount of liquid you would have to consume.
As for "chemicals"? I'd like to see some citation on that.
