Challenges involving numbers tend to capture the attention of social media algorithms, and one such trend that has recently gained popularity is the 12-3-30 treadmill workout. This routine, which involves walking at a 12% incline at a speed of three miles per hour for 30 minutes, has been making waves online. While I haven’t explored many other fitness challenges, there’s a new one catching my eye: the 30-30-3 method.
This approach, developed by board-certified physician Dr. Amy Shah, focuses on consuming 30 grams of protein as your first meal, integrating 30 grams of fiber throughout your day, and enjoying three servings of probiotic foods daily. Mel Robbins recently discussed this method on her podcast after reading from Dr. Shah’s upcoming book, Hormone Havoc. In her discussion, she highlights that this method could lead to benefits like reduced anxiety, enhanced cognitive function, improved fitness, better digestion, and increased energy levels. Naturally, I found myself questioning whether these claims are truly valid. Is this method worth the hype?
To gain more insight, we consulted registered dietitians to evaluate the nutritional principles behind the 30-30-3 method and what it would look like in practice.
Is 30 grams of protein at breakfast beneficial?
If you’re among those who tend to consume minimal protein at breakfast (for reference, two eggs provide just 12 grams), increasing your protein intake could yield significant benefits. According to Erin Jowett, MS, RD, LDN, founder of Integrative Weight & Wellness in Salem, Massachusetts, this approach can create noticeable improvements if you’re transitioning from skipping breakfast or consuming low protein and highly processed foods.
Targeting 30 grams of protein for your first meal is generally a positive goal. Amy Shapiro, MS, RD, founder of Real Nutrition in New York City and lead nutritionist for Butcher Box, explains that this amount can positively impact your blood sugar, energy, and appetite for hours. “Protein at breakfast enhances satiety, curtails cravings—especially for sugars and refined carbs—stabilizes blood sugar levels (reducing mid-morning slumps), preserves lean muscle mass, supports metabolic health, and aids in hormone signaling, which includes hormones that regulate appetite,” she notes. Despite the current hype surrounding protein in various forms—such as protein water or popcorn—it’s essential to prioritize protein intake at breakfast and across all meals. (A reminder: Adults should aim for 1.2 to 1.6 grams of protein per kilogram of body weight, as per the 2025–2030 Dietary Guidelines for Americans. Distributing your protein intake evenly throughout the day maximizes absorption and minimizes digestive discomfort, leading to optimal energy and satiety.)
In summary, the 30-30-3 method presents an interesting nutritional strategy worth exploring. By incorporating more protein, fiber, and probiotics into your daily meals, you may unlock a range of health benefits. However, as with any diet plan, it’s always best to evaluate it within the context of your individual health goals and consult with a healthcare professional for personalized advice.
