The Best Protein Bars for Weight Loss: 20 Dietitian-Approved OptionsPosted: August 16, 2022
Are protein bars good for you? Are they healthy? Do protein bars help you lose weight? This blog post answers these questions and lists the top 20 protein bars that are dietitian-approved and can even help you stay on track with your weight loss goals.
Protein bars are a convenient grab-and-go snack when you’re looking for something easy and quick while still aligning with your health and weigh loss goals. But not all protein bars are created equal and many are no better than candy bars.
There are a few factors to evaluate before determining if a bar can be considered a good choice for weight loss or if it’s a candy bar in disguise. But first, let’s discuss why protein is so important when it comes to your weight loss goals.
Protein and Weight Loss
There’s a good reason that diets higher in protein are encouraged when you’re trying to lose weight. Research has shown that higher-protein diets are linked to weight management, appetite regularity, decreased risk of health problems like cardiovascular disease and even decreased cravings throughout the day.
How much protein should you be consuming?
Specifically, the data suggests that diets containing between 1.2 and 1.6 g protein/kg and meals that contain at least 25-30 grams of protein per meal provide improvements in appetite, body weight management, and other health benefits. Also, protein helps preserve healthy muscle mass during weight loss which is very important since it’s easy to lose muscle when you’re in a state of reducing fat mass.
Furthermore, protein helps promote satiety (the feeling of fullness that you get when you’ve had enough to eat). Eating a diet higher in protein helps curb cravings and helps stabilize blood sugar levels which are also very important for your weight loss goals.
Why you may need a protein bar
Do you need to eat a protein bar to lose weight? The answer is no. But it can definitely be helpful in certain situations including:
Easy post-workout snack. While a real food meal may sound great after a workout, it is not always feasible. This is especially true if you are someone on the go or if you’re a busy mom with a tight schedule. Keeping a good protein bar on hand is easy, versatile and stores really well.
You want to change up your snacks. It’s okay to change up your snacks and choose protein bars on your weight loss journey. I typically find those that have a hard time staying consistent get bored of their meals and snacks which causes them to give up on their goal. What I love about protein bars is that they come in so many different flavors which makes snacking a little more exciting.
You need help reaching your protein goals. Some people struggle with reaching their protein goals because protein takes time to prep and you may not be in the mood for some hard boiled eggs. So having a protein bar on hand is a great way to quickly get 10-20 grams of protein.
Easy choice when you’re in a pinch. I get it, life gets busy and you don’t want to grab fast food when you’re in a pinch. Having a protein bar on hand can help save you money, time and can help keep you stay on track of your weight loss goals.
What to look for in a protein bar
When it comes to choosing a healthy protein bar, understanding what ingredients to look for on the packaging, and looking at the nutrition label, can help you make an informed choice.
First of all, protein bars aren’t necessary and I’m personally a huge advocate for eating whole foods first before any supplements. However, I do like to keep protein bars on hand for when I need a quick healthy snack that holds me over until my next meal.
Some of the best protein bars are made from whole ingredients including nuts and seeds adding a boost of healthy fats, are high in grams of protein, has at least 4 grams of fiber and is low in added sugar and artificial sweeteners. Depending on how you’re eating a protein bar, whether it’s as snack bars or meal replacements, the calorie count will highly vary. If you are eating a protein bar as a snack then choose one with fewer calories (between 200-250 calories), and if it is a meal replacement, choose one with higher calories (around 400 calories).
What makes a healthy protein bar?
- Protein content. Look for at least 10 grams of protein per serving.
- Protein type. Not all protein is created equal. The protein in bars usually comes from dairy or plant sources. The most common are whey protein, soy, eggs, milk, rice, peas, and hemp. If you have any allergies or sensitives, make sure to choose a bar that’s based on a type of protein you can eat without side effects.
- Fiber content. Fiber is important to help keep you full so aim for at least 4 grams of fiber or more per serving.
- Look for whole foods as the main ingredients. While some bars are made entirely of ultra-processed ingredients, some are made from natural ingredients like whole foods. I always try to choose some that are filled with whole foods even if the protein content isn’t ideal. Personally, I choose bars with a better ingredient list than a protein bar that hits all requirements but is packed with additives, preservatives and sugar alcohols.
- Minimal ADDED sugars. The average protein bar is high in sugar so I look for ones with low sugar and no high fructose corn syrup. I’d prefer the bar be sweetened with more whole food sources such as dates and other dried fruits. Dried fruits add fiber and other nutrients versus sugar alcohols which could result in gastrointestinal discomfort like bloating, diarrhea and gas.
20 Best Healthy Protein Bars for Weight Loss
Before we get into the list, it’s important to note that the perfect protein bar does not exist. If they are higher in protein and low in sugars, it’s probably because they use sugar alcohols. And if they are made with whole ingredients, then the sugar content is usually a little higher because they do use dates and other fruits to sweeten the bars. Keeping this in mind, let’s get into it!

Healthy Protein Sources from Whole Foods
Even though this post discusses protein bars, I wanted to include some whole food high-protein options.
The richest sources of dietary protein are meats, poultry, fish and shellfish, eggs, milk and Greek yogurt. Protein can also be found in many plant-based sources including beans and legumes, nuts, seeds, and whole grains. These are all foods that are easy to include in a healthy balanced diet so if you eat a variety of them daily, you most likely get enough protein from your diet.
With so many options on the market, it can be very overwhelming trying to find a healthy protein bar that tastes good and helps with weight loss. However, because protein tends to be the hardest macronutrient to get in to our diet as it usually requires preparation, many people find protein bars to be so convenient. Having a protein bar every now and then when you’re in a pinch will not sabotage your weight loss goals, but I would highly recommend getting your protein from whole sources whenever possible.
I always say “food first,” but if you are needing an easy protein source, some protein bars are an excellent choice.

Skout protein bars and 88 Acres Triple Berry Seed Bar are made in bakeries free of peanuts, tree nuts, gluten, dairy, eggs, soy, and sesame. Gomacro bars are another great option, however, their bars are manufactured in a facility that processes peanuts and tree nuts.
