Time is running short to get ready for swimsuit season. Not to worry. Losing weight (or just maintaining your current hot bod) can be as simple as keeping a food journal.Rebecca Dority, instructor in the Department of Nutritional Sciences at TCU, says keeping a food journal is a great way to reach health goals."I think that many people are surprised at how much mindless eating contributes to overall caloric intake during the day -- especially unplanned handfuls of snack foods, candy and so on," she says.Dority says that keeping a food journal can make you more aware of the foods you consume and keep you accountable in choosing wiser options."My first recommendation for starting a food journal is finding an app or online tool to make the process easier," Dority says. She recalls keeping a paper food journal, looking up each item that she consumed and then writing it in a notebook she took with her everywhere. "That is still certainly an option, but now there are many advanced options that include food items, including brand-name items and restaurant foods."Dority also suggests writing down the foods you consume right after eating them. "I suspect that [by the day's end] most people would have difficulty remembering every food item they consumed during the day," she says.Her final recommendation for beginning a food journal: Measure and input accurate portion sizes. This can be a daunting task, she says, but over time it becomes easier to visually estimate portion sizes.Ready to get started? Here are five apps that can help you on your way.
