4 Best Meal Replacement Bars for Weight Loss

by | Sep 26, 2019

As the name suggests, meal replacement bars are marketed as a simple and healthy stand-in to eating a typical meal. They can be a convenient option for busy people on the go, but many people turn to them to help with weight loss since these bars tend to contain fewer calories than most traditional breakfast, lunch and dinner options.  

How do I find the best meal replacement bars?

Meal replacement bars can be an effective and efficient way to reduce calories in their diets and lose weight. While not recommended as a long term weight loss solution, there are certain bars that can be helpful in weight loss in the short term without compromising healthier long term weight loss goals. 

The Noom team has compiled a list of meal replacement bars for weight loss that may help you drop unwanted pounds without excluding a lot of the necessary nutrients that are needed to maintain good health.  

1. The PROBAR Almond Crunch

The PROBAR Almond Crunch meal replacement bar for weight loss is ideal for anyone with food allergies or lifestyle food restrictions. Vegetarians, vegans, and those who are gluten free can also enjoy this bar because it contains no gluten or ingredients derived from animals. This bar works as a filling and energizing breakfast or lunch replacement but probably doesn’t have enough calories, protein, and other benefits to serve as a proper stand in for dinner. 

Instead of skipping meals throughout your busy class or work day, plant-based protein bars with loads of natural ingredients like this can help you maintain a balanced diet and prevent you from overeating by the time you get a chance to sit down for a regular meal.

Should you use energy bars, protein bars, or nutrition bars for weight loss?

As with any meal replacement diet that relies on a quick fix mentality, the resulting weight loss from any of these bars is virtually always unsustainable. You may also end up eliminating healthy nutrients your body needs in one way or another (because no weight loss bar can serve as a genuine stand-in for a real meal).
