An RD Breaks Down The Recent David Protein Bar Lawsuit

In case you haven’t heard the headlines, David Protein Bars are in the hot seat. Why? They are getting sued for misrepresenting the nutrition facts on their label. The bar was tested in an independent lab and the results showed that the bar contains 400% more fat and 80% more calories than what’s printed on the label. But does this allegation hold any weight? Before you panic, we are going to get to the bottom of what this is about and what you need to know.

First….

When examining this issue more closely, a key discrepancy marker appears to be a lesser known ingredient called EPG (esterified propoxylated glycerol).

EPG is a fat-like compound designed to add a higher fat taste but for a fraction of the calories.

Standard lab testing methods often measure total fat content chemically, but do not always account for how that fat is actually metabolized by the body.

So while a lab may detect a higher “fat content,” that does not necessarily translate to higher usable energy (calories) for the body.

A helpful comparison: artificial sweeteners. They make diet sodas taste incredibly sweet but for zero calories and zero grams of added sugar.

EPG functions in a similar wafe. It’s also safe to use and while not a newer discovery, it’s not well-known either.

So, what does this mean nutritionally?

This means David Protein Bars are still formulated to contain what’s advertised on the label:

  • ~150 calories

  • ~28 grams of protein

  • Minimal carbohydrates

  • Relatively low metabolizable fat

This means that the majority of calories are coming from protein, not fat—despite what a basic lab fat measurement might suggest.

Are these bars a good choice?

Like most nutrition questions, the answer DEPENDS.

These bars may be helpful for:

  • Individuals struggling to meet daily protein needs

  • Busy schedules where convenience matters

  • Situations where a low-calorie, high-protein option is desired

They may be less ideal for:

  • Pre-workout fueling (they’re relatively low in carbohydrates)

  • Individuals with higher overall energy needs

  • Those looking for a more balanced macronutrient profile for sustained energy

The bigger picture

From a clinical standpoint, this situation highlights an important point:
Not all nutrients measured in a lab translate directly to how the body uses them.

It also underscores the importance of:

  • Understanding ingredient functionality

  • Interpreting nutrition data in context

  • Avoiding quick conclusions based solely on isolated test results

Final thoughts

While the lawsuit raises valid questions about labeling clarity and testing methodology, the current evidence suggests that the discrepancy may be more about how ingredients like EPG are measured vs. how they are metabolized, rather than intentional misrepresentation.

As always, OUR approach remains the same:

  • Food first is the foundation of good nutrition

  • But protein bars and supplements can absolutely have a place when used thoughtfully

For many people, a product like this can be a convenient, effective way to support protein intake—just not a one-size-fits-all solution for every nutritional need.
