When it comes to losing weight, the most important rule of thumb is to consume fewer calories than you’re taking in each day. But cutting calories doesn’t have to mean eating less food. In fact, simply focusing on healthier food choices may be a more sustainable weight-loss strategy than trying to reduce portion sizes, a new Penn State University study suggests.
The findings come from a small new clinical trial, published in the journal Appetite, which compared food consumption among 39 women who had taken part in a previous year-long weight-loss study and 63 women who were not part of the earlier study. All of the women came to the study lab once a week for four weeks to eat a meal, with varying portions of seven different foods served each week.
