The 30/10 Rule
30 grams of protein and 10 grams of fiber in every meal. A nutrition principle dietitians love and the foundation behind every serving of Happy Viking.
Explore the science, benefits, and ingredients behind the 30/10 rule.
The 30/10 rule is a simple nutrition framework:
30 grams of protein + 10 grams of fiber per meal
This balance helps support:
Rather than tracking complex macros, the rule focuses on two nutrients most people under-consume or distribute poorly throughout the day.
Protein and fiber form the foundation of balanced nutrition.
Protein supports muscle maintenance, recovery, and sustained energy. It also helps promote fullness after meals, making balanced nutrition easier to maintain throughout the day.

Fiber supports digestive health and helps regulate appetite by slowing digestion. It also contributes to more stable energy levels and long-lasting fullness after meals.

Daily energy blend with thoughtful ratio of protein to fiber
What stands out to me is the thoughtful ratio of protein to fiber content. These shakes are formulated with 30 grams of protein and 10 grams of fiber per serving. While some products have one or the other, it’s great to see a shake that can provide patients with meaningful amounts of both protein and fiber at the same time. When taken together, protein and fiber can help stabilize energy levels in the body and may reduce sharp fluctuations in blood sugar. More available energy may help the brain better perform cognitive functions, potentially promoting things like focus, clarity, and mental endurance.

Great breakfast!
I love this meal replacement, mixes well, tastes great, not chalky or clumpy. I like the vanilla because I can mix it with so many things.
