UNDATED (WIFR) -- A new study from the PEW Research Center finds 8% of people surveyed use an app or online tool to track their health.
Studies have shown people who keep track of their calories and exercise whether on paper or online increase their chances of losing weight. Popular diet apps like "Lose It" and "MyFitness Pal" make it more convenient, but experts warn the apps only work if you're totally honest and record everything you eat. Another thing to keep in mind, some apps can vary.
Some of the apps I find kind of overestimate how many calories you burn when you exercise,” says Martha McKittrick, a registered dietician. “So if you walked for a couple of miles and it says you burned 600 calories, be careful not to eat an extra 600 calories.”
There are more than 30,000 health apps on the market. Experts say it's always a good idea to read the reviews before you buy one.
