The Truth about Carbs and Weight Loss

By Elisa - Jenny Craig

Reviewed by Briana Rodriquez, R.D.

Science-Backed

Carb lovers, rejoice! Research suggests pasta may actually contribute to weight loss, if eaten in moderation.1 And pasta isn’t the only carbohydrate that can be good for you. Although many recent weight loss trends — like the keto diet — suggest that you need to cut out carbohydrates entirely, those trends are missing an important piece of information: Carbohydrates are an important source of energy for your body. We sat down with Jenny Craig’s Registered Dietitian Nutritionist, Briana Rodriquez, to get the truth about carbs — find out how they can be part of a healthy diet and how they may even help you lose weight.


All carbs aren’t “bad.”

Simple carbohydrates are digested quickly and provide the body with a jolt of glucose, also known as blood sugar.2 Many foods containing simple carbohydrates, including candy and pastries, can be full of refined sugar. But if you’re trying to lose weight, you may want to reduce your sugar intake. Nutrient-rich sources of natural sugar include fruit and root vegetables, which contain fructose, and dairy products, which contain galactose.3


Complex carbohydrates are full of fiber, which helps them to be digested slowly and to release glucose more slowly than simple carbs.2 Enjoying meals that include complex carbs can help fill you up, which may help with weight management. Vegetables, fruits, legumes and whole grains are all great sources of complex carbohydrates. 


If your goals include weight loss, Rodriquez suggests eating smaller amounts of carbohydrates, including fruit and starchy vegetables (like corn, peas and potatoes). Instead, opt for lower-calorie carbohydrates that are nutritious and filling by enjoying delicious non-starchy vegetables: Broccoli, asparagus, spaghetti squash, cucumbers and eggplant are all great options. 

They can be great sources of fiber and resistant starch.

Carbohydrates can be rich in dietary fiber and resistant starch, two components that may help support your health. 


Dietary fiber is found in fruits, vegetables and whole grains. There are two main types: soluble fiber and insoluble fiber. 


Soluble fiber can be found in beans, nuts, seeds, and certain fruits and vegetables.4 This type of fiber dissolves in water and forms a gel that helps to slow digestion.5 This is important, research suggests, because it increases the amount of time the nutrients interact with processes in your body that signal satiety.6


Insoluble fiber does not dissolve in water and can be found in vegetables and whole grains. Because it remains mostly intact during digestion, insoluble fiber helps food to pass through the body.5


Resistant starch is found in a variety of foods that also contain fiber, including legumes, grains, potatoes, and more. Similarly to soluble and insoluble fiber, resistant starch is broken down slowly by the body and may help you to feel satisfied.7


 And it’s not just beneficial for digestion, eating a fiber-rich diet may support heart health, as well. A review of multiple studies found that people who consumed the highest amounts of dietary fiber could reduce their risk of developing coronary heart disease and stroke between 7% to 24%.8  

You don’t need to completely avoid carbs to lose weight.

Take the keto diet, for instance, that emphasizes high-fat, moderate protein meals and discourages practitioners from eating too many carbohydrates. Maintaining ketosis — when your body burns fat instead of glucose for fuel — can be tricky to maintain and may not work well for everyone, says Rodriquez. 


With that in mind, it’s not necessary to sacrifice carbohydrates in the name of weight loss. There’s an easier way to have your carbs and eat them, too: enjoying balanced meals in appropriate portions and putting an emphasis on complex carbohydrates.


“Carbohydrates are a crucial part of a healthy diet,” Rodriquez explains, “but it’s important to keep an eye on portion sizes and the types of carbs you eat.”


At mealtimes, Rodriquez suggests making fiber-rich non-starchy vegetables the stars of your plate, then adding smaller amounts of protein, fruit, healthy fat and starch. (This simple portion size guide can help!)


“If you find yourself feeling hungry throughout the day, you may want to incorporate more resistant starch and fiber-rich non-starchy carbs into your meals,” says Rodriquez. “They’re often low in calories, are nutrient-dense, and may help you feel full and satisfied after eating, so you’re less likely to munch on unhealthy snacks in between meals.”

Your DNA could play a part in how your body uses carbs.

Certain genetic markers could indicate how well your body uses carbohydrates and point you in the right direction. 


Jenny Craig’s DNA Decoder Plan provides delicious, perfectly-portioned menu plans based on your results and reveals 15 key DNA insights, including how efficiently your body processes carbs, fat and protein; how well you’re likely to respond to cardio and strength training exercise; and more.


And while genetics could play a part in your weight loss efforts, your lifestyle choices matter, too. Actively practicing healthy habits, like reaching for nutrient-dense sources of carbohydrates, enjoying mindful portions and incorporating exercise into your day could all have positive effects on your weight loss efforts. 

When it comes to carbs (and weight loss), balance is key

Don’t want to give up chocolate cake, pizza and pasta? You don’t have to.


“If you don’t have to worry about cutting out your favorite foods while following a weight loss program, it’s easier to enjoy your meals and focus on eating nutritious ingredients in healthy portions,” says Rodriquez. 


Consider portion-friendly alternatives, like enjoying a single serving of Chocolate Lava Cake, reaching for a slice of cheesy Pepperoni Pizza with extra veggies to use as toppings, or having a plate of Chicken Fettucine Alfredo with a side of vegetables.
