The Experiment: 0 grams of Added Sugar. No candy, no soda. But also: No Pasta Sauce (it has sugar), No Bread (sugar), No Ketchup (mostly sugar).

I realized quickly: Sugar is in everything.

> DAY 1: THE DISCOVERY PHASE

I went grocery shopping. I felt like a detective finding evidence of a crime.

  • Granola: 12g Added Sugar (It's labelled "Healthy"!)
  • Yogurt: 18g Added Sugar (That's a candy bar)
  • Sriracha: Sugar is the 2nd ingredient

I ended up buying eggs, spinach, and plain meat. My diet became "Paleo" by necessity.

> DAY 2: THE HEADACHE

At 2 PM, the headache arrived. It sat behind my eyes. This is the "Keto Flu." My brain was screaming for quick glucose.

I ate an apple. It tasted like the sweetest treat on earth. Fruit sugar (Fructose) was allowed, but processed sugar was banned.

Clarity
DAY 7
Energy

> DAY 3: THE RAGE

I snapped at my friend for chewing too loudly. I almost cried because the WiFi was slow.

Sugar releases opioids and dopamine in the brain. I was literally going through drug withdrawal. My brain was trying to emotionally manipulate me into eating a donut.

> DAY 5: THE TURN

I woke up, and the fog was gone. I didn't need coffee.

My energy was stable. Usually, I crash at 3 PM. Without the insulin spike/crash cycle of a sugary lunch, I was a flat line of productivity.

> THE TASTE BUD RESET

On Day 7, I ate a bell pepper. It tasted sweet. Like, actually sweet.

My taste buds had un-numbed themselves. Modern food is so hyper-palatable that we lose the ability to taste natural flavors. Resetting that baseline was shocking.

> CONCLUSION

I am back on sugar now, but in moderation. I will never look at Ketchup the same way again (It's just red corn syrup).

If you have brain fog, try quitting sugar for 3 days. The clarity is worth the Day 2 headache.
