Top 10 Low-Carb Diet Protein Bars

The best diet to reduce body fat and build lean body mass is a diet high in fat, moderate in protein, and low in carbohydrates. While fat (and, annoyingly, carbs) are all-too-easy to eat, it can sometimes be harder to hit protein goals for the day. Thankfully, some bright cookie invented protein bars – the perfect pre- or post-workout snack, and an excellent way to hit your macros.

There are a lot of protein bars on the market, but it can be hard to know which ones are the best (and which ones taste like recycled cardboard). In general, protein bars come in two varieties – high protein/low carb ones (they’re the ones we want), or otherwise full-on meal replacement bars – high in both protein AND carbs (we don’t want that).

The best protein bars are made with whey protein because it’s absorbed quickly into the body, making them particularly well suited to post-workout. In addition, they can provide a great source of fiber, which is sometimes hard to get on a low-carb diet. Just be careful of the artificial sweeteners in them – not because they’re mysteriously toxic, but because some of them actually ARE metabolized by the body, and can kick you out of ketosis (if that’s your goal).

Overall, a low-carb protein bar should give you energy, sustain your insulin levels, not contain a lot of the bad artificial sweeteners (erythritol is great, however), and taste delicious. Read on for ten of the best protein bars (by macro content).

 

  1. Quest Bar

Quest is the best protein bar manufacturer on the market, with great taste and the perfect balance of protein, carbohydrates and fiber. It’s gluten-free and does not contain trans. The nuts in the Quest Bar contain natural, healthy oils. The best part about the Quest Bar – it comes in many different flavors to satisfy your sweet tooth. Seriously, Quest bars are my savior – they give you a massive fiber boost, they’re low calorie (under 200 per bar), and super low carb. SO MANY FLAVORS!

  1. ISS Research Oh Yeah! Victory Bars

The Victory Oh Yeah! Bars are also gluten-free and contain no sugar alcohol. The bars are (relatively) low in sugar and contain healthy fats. Milk protein, calcium caseinate and whey provide a healthy snack that aides in the growth and quick recovery of the body’s muscles. It’s filling and gives you energy before your work out. It comes in a variety of tasty flavors including Chocolate Chip Cookie Dough, Fudge Brownie, Peanut Butter Cup and Vanilla Almond. My only problem with these are the fact that they’re a bit higher in carbs than you want on a keto diet.

Ideal Bar’s protein bar is ideal because it blocks food cravings, boosts energy and helps activate weight loss. These bars also contain 23 vitamins and minerals to enhance overall health. It comes in delicious Cookies and Cream, Cran-Granata, Lemon Poppyseed, Raspberry Jelly and Choco-Raspberry flavors. However, despite its somewhat more attractive nutrient profile, it IS a little high in carbs.

Again, however, it’s rendered somewhat less than ideal by a high carb-count.

  • 14 grams protein

When eating protein bars as quick energy snacks or as meal replacements, it is important to find the protein bars with the best combination of protein, fiber and carbohydrates. Hopefully the list here helps make your choice a bit easier, but I advise trying a good range of different bars – what one person loves may taste like gritty cardboard to another. Find the bars that you love! And of course, if you have any suggestions or if you feel I’ve unfairly excluded a bar, let me know in the comments below!
