No matter how you spin it, there are only two proven ways to lose weight naturally: diet and exercise. When it comes to diet, you can move the number on the scale by tackling it from two angles: eating healthier and eating less. Today we’re talking portion control. Portion control doesn’t mean restricting yourself to depressingly tiny bites of food. It does mean eating only as much as you need to feel full and stopping before you overdo it. It’s also important to understand what a proper serving size actually looks like. Americans are notorious for their “supersize me” portions! A number of scientific studies have found that when people are provided with more food, they eat it. On the converse, when they’re given pre-portioned meals over an extended period of time, they lose more weight than those who eat freely. Use these 5 portion control tips to lose weight the natural way, giving your body the nutrients it needs in healthy amounts.
