A Royal Spirulina Protocol
Heavy Duty
Plant-Based Protocol
A seven-day meal framework drawing on Mike Mentzer’s rational, balance-first nutrition philosophy — built to flex between vegetarian and vegan eating, enriched with spirulina and fresh pressed juices.
Duration
7 Days
Daily Range
~2,500 kcal
Protein
120–140g
Spirulina
5–7g / day
I. The Philosophy
Mentzer pushed back against the extreme-protein, ultra-strict meal culture of his era. His actual advice was quieter: eat rationally, hit your calories, don’t fear carbs, keep it sustainable. This plan honors those principles while swapping animal proteins for plant sources — and layering in the nutrient density of spirulina and fresh juices.
1
Carbs Are Fuel
Roughly 50–60% of calories from quality grains, fruit, and legumes. Mentzer argued bodybuilders’ carb-phobia was irrational.
2
Moderate Protein
Up to 1.2g per pound was his ceiling, not a floor. This plan lands at roughly 0.8–0.9g/lb for a 180 lb person.
3
Calories First
Hit your daily target; don’t obsess over macros. A food diary helps more than a scale ever will.
4
Sustainable
Room for flexibility. An occasional treat is a feature, not a failure — Mentzer himself ate ice cream without apology.
II. Sunday Prep
The whole protocol hinges on two hours on Sunday. Cook these in parallel — three pots on the stove, legumes in a pressure cooker — and you’ve unlocked every lunch and dinner for the week.
Grains — Batch Cook
- Durum wheat berries (1 cup dry) — 60 min
- Pearl barley (1 cup dry) — 40 min
- Quinoa (1 cup dry) — 15 min
- Buckwheat (½ cup dry) — 15 min
Legumes — Pressure Cooker
- Black beans (soaked, 1 cup dry) — 25 min
- Chickpeas (soaked, 1 cup dry) — 25 min
- Red lentils (no soak needed) — as needed
- Green split peas (no soak) — as needed
III. Daily Rhythm
These anchors stay consistent across all seven days. They carry the breakfast calories, deliver the spirulina, and work the fresh juices in at times that maximize absorption.
On waking
Fresh celery juice · 16 oz
Empty stomach. Sipped slowly. Wait 15–20 minutes before anything else.
8:30 am
Breakfast · ~650 cal
Oatmeal with milk (vegan: oat or soy milk), banana, peanut butter, honey (vegan: maple syrup), plus 3 scrambled eggs with cheese (vegan: a tofu scramble — 6 oz firm tofu — with nutritional yeast, turmeric & black salt). Optional: 1 tsp spirulina in a small side smoothie.
10:30 am
Green juice · 16 oz
Cucumber, celery, green apple, kale or spinach, lemon, ginger. Between meals — not with food.
1:00 pm
Lunch · see daily rotation
Grain-and-legume combination built from Sunday’s prep. Takes five minutes to assemble.
4:00 pm
Spirulina smoothie · ~400 cal
Milk (vegan: oat or soy milk), frozen banana, peanut butter, whey or pea protein (vegan: pea or hemp protein), 1–2 tsp spirulina, berries, optional hemp seeds. The largest spirulina dose of the day.
5:00 pm
Pre-dinner beet-carrot juice (optional) · 12 oz
Carrots, beet, apple, ginger, lemon. Skip if you’re not training in the evening.
6:00 pm
Dinner · see daily rotation
The second cooked meal of the day. Heavier, more variety. Ice cream (vegan: coconut or oat-milk ice cream) once or twice a week — Mentzer’s intelligent cheat.
IV. The Seven Days
Each day rotates a different grain-and-legume anchor through lunch and dinner. Breakfast, juices, and the afternoon smoothie stay constant. Vegan swaps appear inline in italics throughout.

V. The Spirulina Protocol
Daily Dosing
- Week 1: start at 1 tsp (~3g) daily, split morning & afternoon
- Week 2+: build to 1–2 tsp (~5–7g) daily as tolerated
- Morning shot: 1 tsp in 4 oz water or lemon water on empty stomach
- Afternoon smoothie: 1–2 tsp blended with banana, berries, peanut butter
- If using phycocyanin extract: follow dropper on bottle, add to morning juice
Best Practices
- Take on empty stomach or in a cold smoothie for best absorption
- Avoid mixing with coffee or hot liquids — heat degrades phycocyanin
- Sweet flavors (banana, berries, honey/maple) mask the earthy taste
- Drink juices within 15–20 min of pressing for peak nutrient retention
- Keep individual juice servings to 16 oz or less to avoid sugar spikes
VI. The Vegan Protocol
Mentzer’s “just eat balanced” advice from the 1970s assumed eggs and dairy were on the table. Plant-only eating works beautifully with his framework — but a handful of nutrients need deliberate attention. Here’s what to watch, and what to add.
Systematic Swaps at a Glance
| Component | Vegetarian | Vegan |
|---|---|---|
| Breakfast protein | 3 eggs + cheese | 6 oz tofu scramble + nutritional yeast |
| Milk (oatmeal, smoothie) | Dairy milk | Oat, soy, or pea milk |
| Sweetener | Honey | Maple syrup |
| Protein powder | Whey or pea | Pea, hemp, or rice blend |
| Cheese (salads, tacos) | Feta, parmesan, cheddar | Nutritional yeast, vegan feta, cashew crema |
| Yogurt / sour cream | Greek yogurt, sour cream | Cashew or coconut yogurt, cashew cream |
| Butter (risotto) | Regular butter | Vegan butter or olive oil |
| Ice cream (cheat) | Dairy ice cream | Coconut or oat-milk ice cream |
Nutrients to Prioritize
Vitamin B12
Not reliably available from plants. Supplement is non-negotiable on vegan — a weekly dose of 2,500 mcg or daily 250 mcg cyanocobalamin.
Fortified milks · supplement
Iron
Plant iron absorbs better with vitamin C. Pair lentils and beans with citrus, tomato, bell pepper, or berries at the same meal.
Lentils · tofu · spinach · spirulina
Zinc
Easily covered by your existing pantry plus a daily handful of seeds. Soaking legumes overnight boosts absorption.
Pumpkin seeds · chickpeas · hemp seeds
Omega-3 (ALA)
Add 1–2 tbsp ground flaxseed or chia to your morning oatmeal, or keep walnuts in the afternoon smoothie.
Flax · chia · walnuts · hemp
Vitamin D
Universally worth supplementing in winter regardless of diet. 2,000 IU D3 (algae-derived for vegan) daily is the standard dose.
Sunlight · supplement
Calcium
Fortified plant milks plus greens (kale, bok choy), tahini, and tofu easily cover the RDA without dairy.
Fortified milks · tahini · tofu · kale
Macro Considerations
Vegan mode runs roughly 10–15g lower on protein and slightly leaner on fat compared to the vegetarian version, due to losing eggs and cheese. Close the gap with one of these additions: an extra scoop of protein powder in the smoothie, 2 tbsp hemp seeds sprinkled across the day, or bumping the tofu scramble to 8 oz. Total calories remain within 100–150 of each other, which is negligible at this scale.
VII. Protein Pairings
Mentzer didn’t worry about “complete proteins” — modern science confirms you don’t need to combine them at every meal, only across the day. These natural pairings still maximize amino acid profiles.
