“How can I lose weight?” Over time, millions of Americans have asked themselves that question. In fact, between 2015 and 2018, nearly one in five adults older than 20 reported that they were following a particular eating plan on a given day, according to a recent study by the Centers for Disease Control and Prevention (CDC).right up arrow The most common diet followed by participants in the study was a weight loss or low-calorie diet, followed by a diet for diabetes management, a low-carb diet, and a low-fat or low-cholesterol diet.
But even among these few approaches, there are an overwhelming number of different programs available, and finding the right one can prove challenging. After all, there’s no one-size-fits-all plan that’s perfect for everyone.

How to Pick the Best Diet Plan for You

Before choosing a health or weight loss approach, it’s important to do some self-evaluation by asking yourself some questions.

What Can You Live With in the Long Term?

“There are many diet plans on the market today that promote good health,” says Emily Kyle, RDN, who is in private practice in Rochester, New York. “The key is finding one that does not cause you stress or agony.” Ask yourself questions such as: Would the diet guidelines make you happy? Anxious? Stressed? Are you able to follow them long term? “Factors such as enjoyment, flexibility, and longevity should be strongly considered,” adds Kyle.

If the diet is a quick fix rather than one that promotes lasting lifestyle changes, this could pose a problem. In particular, extreme diets that promise big weight loss up front aren’t always sustainable — and you may end up overeating or even binge eating if you feel deprived. “Consider if the diet’s habits are ones you can continue throughout your lifetime, not just 21 or 30 days,” says Angie Asche, RD, a sports dietitian in Lincoln, Nebraska.

Which Diet Program Is Best for Your Overall Health?

Some diet plans, such as the MIND diet and the DASH diet, are meant to focus on certain areas of health — and weight loss may be a bonus. Others are created with weight loss as a primary goal. “It is important to remember that we are all very unique individuals,” says Kyle. “We all have different states of health and different lifestyles, which could affect what diet plan is best for us. That means that you should not be considering what is working for your friends or family members — and instead should pay attention to what works for you individually.”

Many diet plans cut out entire food groups, which can create nutrient deficiencies as well as health problems. For instance, if the diet is very low in carbohydrates and you have type 1 diabetes or type 2 diabetes, it’s probably not a good fit. And if it’s too restrictive and you’re pregnant or breastfeeding, it’s not a good idea, either. Keep in mind that pregnancy is not a time for weight loss. Speak with your doctor before making any changes to your diet if you are pregnant or breast-feeding.
