interesting. I give the manufacturer Brownie points for creativity.
Nevertheless, not only has the Paleo diet's relevance to the evolution of homo sapien sapien been debunked.....but there's a strong case that processing grains or pretty much anything into a flour or powder, bypasses the satiation, digestive, absorption, elimination, and metabolic mechanisms we have evolved, all with deleterious effects such as insulin spiking, fatty liver, excessive weight gain.
As an example, consider the graphs below.
The upper is weight gain by three different groups of mice that ate ad libitum.
The black squares were controls and fed standard high carb mouse chow pellets.
White circles = standard Western diet pellets with relevant portions of sugar and fat.
Grey squares = pellets same as white circles except higher fat.
The result was weight gain on the Western and high fat diets, well above the control pellets.

Now consider the bottom graph.
It shows what happened when the three groups were given the food not as pellets but as powders.
bodyweight gains were similar! So the three groups over-ate to the same degree!
What can be inferred?
When it comes to satiation and weight gain, macronutrient ratio may be less important than whether food is processed (refined) or not.
Pre-processing food bypasses digestive and absorptive machinery, and satiation signaling.
So the Paleo, low carb, and PBWF groups need to promote the same message - eat less if any, refined and processed foods!
Refining food might have been important for our ancestors to help extract as many Calories as possible for the least thermic effect of food, when food was scarce, and manual labour compensated blood glucose spiking.
However, in this day and age, the same cannot be said!
