Are ChocZero Chocolate Squares Keto Friendly?

At the time of writing this post, I’ve been on the ketogenic diet for over four years and logged over 200 blood ketone tests in an effort to estimate the effects of food and ingredients on my ketosis, including those in ChocZero chocolate.

A while back I ordered a ChocZero variety pack on Amazon without looking too carefully at the ingredients and nutrition facts. Unfortunately, after they arrived I noticed they weren’t as keto friendly as I had hoped, but how does it stack up against other low carb chocolate? In this post, I’ll evaluate ChocZero chocolate, and give it keto friendly grades.


Savage Fuel Keto Friendly Grades:

  • A: Completely compatible, positive or no impact on ketosis.

  • B: Highly compatible, but don't go too crazy.

  • C: Moderately compatible, be mindful and limit intelligently.

  • D: Barely compatible, detrimental to ketosis and not recommended.

  • F: Not compatible, overdo it just a little and kiss your ketosis goodbye.

Keto Friendly Grading Factors:

  • Net Carbs per Serving: How many carbs are in this thing?

  • Net Carbs per 100 calories: Since serving sizes often vary significantly, a net carb per 100 calorie ratio is a more consistent measure of keto-friendliness than net carbs per serving. Lower ratios are also an indicator of higher fat content because fat has more calories per gram than protein and carbohydrates.

  • Sugar: Sugars have a higher glycemic index and larger negative impact on ketosis than other carbohydrates.

  • Hidden Carbs: Hidden carbohydrates are based on the caloric values and glycemic indexes of ingredients sometimes classified as fibers or sugar alcohols.

  • Easy to Overeat: Some foods are easy to over-eat and require extra willpower to limit overeating which is an important factor to consider.

  • Nutritional Density: Foods that are relatively high in net carbs per 100 calories but are high in nutrition per calorie can still be worth eating like broccoli and cauliflower.

RULE of thumb for net carbs per 100 calorie ratio:  0-1 great, 1-2 ok, 2-3 caution, 3+ red alert

ChocZero Chocolate Squares Keto Friendly Grades:

Overall factors: 3-5g of soluble corn fiber per 10g square, I normally count 10% of this kind of fiber as net carbs but because ChocZero uses a tiny 10g serving size, it's not practical to add 0.3-0.5g of net carbs per serving but keep in mind if you eat five of these squares (the equivalent of one ChocoPerfection bar/serving) you'll be getting 12-25g of soluble corn fiber which will add 1.2g to 2.5g hidden net carbs to the total. Also low nutritional density and ver easy to overeat.

  • Milk Chocolate: D+
    1g Net carb per 50 calorie 10g square
    2g Net carbs per 100 calories (Orange)
    1g Sugar

  • 85% Cocoa Dark Chocolate: D+
    1g Net carb per 45 calorie 10g square
    2.2g Net carbs per 100 calories (Orange)
    0g Sugar

ChocZero Chocolate Squares Keto Friendly Conclusion:


You could have a few pieces of ChocZero and be fine, but I like to make sure my desserts are binge-proof. Knowing if I go a bit overboard, I’ll still be in ketosis the next day is important to me, especially with desserts like these which are so easy to over-eat. Luckily there are more keto friendly dessert options out there, so we can get our fix without risking our sacred ketones!
