"Most diets are restrictive, challenging to follow, and are unrealistic to keep up with long-term," warns Sandy Younan Brikho, RDN, owner of The Dish On Nutrition.
It's a simple behavioral trick that'll reap big benefits over time. Brikho says getting into the habit of always covering half of your dinner plate in vegetables helps increase your fullness, prevent overeating, and help you get the nutrients you need.
Even if your metabolism hasn't decreased, you may be burning fewer calories because you're not as active every day as you once were or maybe you're not getting adequate sleep.
Making sure you eat enough protein every day is the most important eating habit to adopt, according to Katie Tomaschko, RDN with Sporting Smiles.
"Processed sugar is everywhere—even seemingly healthy foods like yogurt and cereal sometimes contain a lot of added sugar," says Janet Coleman, RD for TheConsumerMag.
Getting into the habit of carrying a water bottle around with you in the car, at work, while shopping, can help you lose weight quickly for a number of reasons, says Tomaschko.
In other words, choose more complex carbohydrates like beans, quinoa, 100% whole grain bread, and steel-cut oatmeal. Complex carbs are rich in fiber, which helps us stay feeling full longer, so we snack less between meals, says Laura Krauza, RDN, owner of Waistline Dietitian.
