i didn’t expect changing what i eat to be the simplest productivity upgrade i’ve made this year.
but after my first week of eating 7 out of 10 meals seafood-based, the difference is hard to ignore.
clearer focus. steadier energy. fewer crashes. it’s subtle, but it adds up.
i’ve always loved seafood, but i’ve also tried to stay “balanced” with my meals for the sake of health. this week, i leaned into what i actually wanted… and the results were obvious.
🧠 why seafood actually boosts productivity:
1. high-quality protein = stable energy + better brain function
protein from seafood helps regulate blood sugar, avoiding the crash that sneaks in after carb-heavy meals.
amino acids like taurine and tyrosine support dopamine production - the same pathways that fuel motivation, mental clarity, and quiet, steady focus.
2. omega-3 fatty acids = focus + cognitive support
fatty fish like salmon, toro, mackerel, tuna, sardines are packed with DHA, a structural component of brain cells.
omega-3s support memory, attention span, cognitive flexibility, and reduce brain fog. they also lower inflammation, which drains mental energy over time.
3. micronutrient density = fewer crashes
seafood is naturally rich in:
• vitamin D (mood + energy regulation)
• B12 (nerve health + energy metabolism)
• iron + zinc (oxygen delivery + sustained focus)
• iodine + selenium (thyroid support + steady energy)
4. clean fuel = less digestive load
meals like sashimi, tartar, or lightly cooked seafood are easy to digest.
less energy spent on digestion means more for your brain.
fewer refined carbs = no big insulin spikes, no energy dips.
none of this is medical advice! just what’s been working for me.
but if you’re running hard, thinking hard, or building something that needs your full focus, it’s worth experimenting with how you fuel. 7 replies

Towa📍NYC
⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
DIY hand roll set - tuna, salmon, yellowtail, Ikura
$29 but I used a coupon for a $7.25 discount at checkout*
The best quality sushi I’ve had delivered to me in NYC under $30! It came with 2 mini reusable freezer packs that kept everything cold even in this unbearable heat wave. Large portions too, I was full without finishing all the sushi rice underneath. Incredibly fresh, real ginger, good soy sauce, great nori seaweed, even the japanese rolled omelet was excellent with just the right amount of sweetness and added delightful texture!
*this does not include delivery fees, tax, etc. 4 replies
