What is 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.

The 30/10 Nutritional Engine

Protein and fiber form the foundation of balanced nutrition.

Protein

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

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.

Why Experts Love Our Recipe

Dr. Charmaine Gibson (OB/GYN)

"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."

Arpita Patel, NP (Family Medicine)

"I really like how Happy Viking pairs acacia fiber with probiotics so that it can support gut health while also helping people meet their daily protein and fiber needs. Acacia is a soluble fiber that can also function as a prebiotic, meaning it can help nourish helpful microbes in the gut. It has been used in research to positive influence these gut microbes and promote gradual improvements in gut health and function. Because it is generally well-tolerated and processed slowly, acacia may help reduce GI discomfort as well. Combined with probiotics, which are beneficial bacteria themselves, it can more broadly support digestive comfort and regularity."

Dr. Christy Arthur (Primary Care)

"Happy Viking can be a great vegan meal replacement for people that need help meeting their protein needs. The proteins in this formula are derived from yellow peas and brown rice, which can form what is considered a “complete protein.” This basically means it contains the essential amino acids your body cannot make on its own, much like animal-based proteins. Emerging studies suggest that some pea-based and mixed plant proteins can help build lean muscles at levels similar to milk or whey protein. There is also fiber in this formula, along with a range of other nutrients that may benefit gut, immune, and metabolic processes. As a whole, I feel optimistic about this meal shake as a vegan protein source and for general health and wellness.

Dr. Craig Petry (Family medicine)

"I would suggest this drink as an easy way to support your skin health and more general wellness. I like how it can supply amino acids that the body needs for the everyday maintenance of the skin and connective tissues. It also contains vitamin C and different plant ingredients that can provide antioxidants, which may help protect the body against cellular damage. Preliminary research suggests that diets rich in antioxidant plants may be associated with improvements in markers of skin health, so that it encouraging to see. From a nutritional standpoint, I see value in these ingredients for maintaining the skin, connective tissues, and other important aspects of everyday health."
