The 30-30-3 framework replaces a diet identity with three measurable daily anchors: 30 grams of protein in the first meal, 30 grams of fibre across the day, and three servings of probiotic foods. The first-meal protein target is a mnemonic and starting anchor, not the person's total daily protein requirement. Fibre is distributed across meals, while probiotic foods can come from many cultures: yogurt, kefir, probiotic cottage cheese, kimchi, sauerkraut, miso, natto, or raw apple cider vinegar. Because the method specifies nutritional functions rather than a fixed menu, it can sit inside vegan, vegetarian, paleo, or gluten-free eating. The output is a repeatable plate-planning rule designed to make adequate protein, fibre, and fermented food intake easier to remember and execute.
Origin
Dr. Amy Shah introduced 30-30-3 from her book Hormone Havoc as a research-based alternative to diet trends.
Core principles
- 01Structure food around additions rather than a restrictive diet label
- 02Front-load enough protein in the first meal
- 03Feed the gut with fibre across the whole day
- 04Use probiotic foods daily to support the microbiome
- 05Apply the framework across vegan, paleo, gluten-free, or other preferences
How to run it
- 1
Anchor the first meal with protein
Build your first meal around 30 grams of protein. The meal can happen later in the morning and the protein may be split if needed.
Pro tip Eggs with extra egg whites and probiotic cottage cheese are one example from the episode.
Watch out Thirty grams is not the total daily protein target.
- 2
Accumulate fibre across the day
Plan vegetables, berries, legumes, whole grains, or other suitable fibre sources across meals until the day reaches roughly 30 grams.
Pro tip Unlike the protein anchor, this target belongs to the whole day.
Watch out Increase fibre appropriately for your tolerance and medical needs.
- 3
Add three probiotic servings
Choose three servings from fermented foods you tolerate and enjoy, such as yogurt, kefir, kimchi, sauerkraut, miso, or natto.
Pro tip Look to traditional foods from your own culture for practical fermented options.
- 4
Fit the rule to your diet
Keep your chosen dietary pattern while changing the ingredient sources that satisfy each number.
Pro tip Judge the day by the three anchors, not by whether it carries a fashionable diet label.
In the wild
A founder who does not want breakfast at 7 a.m. eats her first meal at 10:30 instead. She uses an egg scramble with extra egg whites and probiotic cottage cheese for protein, berries for fibre, then adds vegetables and two more fermented servings later in the day. She follows the framework without forcing an early meal or adopting a new diet identity.
→ Protein, fibre, and probiotic intake become visible daily anchors instead of vague intentions.
Common mistakes
Reading the first 30 as the daily total
The first number refers only to protein in the first meal. Total protein needs vary by person and activity.
Treating it as another restrictive diet
The framework is designed to work across dietary preferences by adding functional targets, not prescribing one fixed menu.
Ignoring food tolerance
Probiotic and fibre sources still need to suit allergies, intolerances, and individual medical needs.
Is it for you?
Best for
Adults who want a flexible daily nutrition structure without adopting a named restrictive diet.
Not ideal for
People with allergies, intolerances, medical diets, or protein and fibre limits that require clinician-led personalisation.
From the transcript
“it is called the 30-30-3. So, 30-33. 30 g of protein in your first meal, so in the morning. 30 g of fiber throughout the…”
“you could be gluten-free, you can be paleo, you can be vegetarian, you can be vegan, but if you just follow the framework”
