Ever notice how a bad gut day and a foggy, flat, or anxious day tend to show up together? That's not a coincidence. Your gut produces around 90% of your body's serotonin, most of your mood and mental clarity is being shaped from the inside, not just the outside.

In case it helps, here's a simple week-long protocol I've seen make a real difference:

• Eat protein within 30 minutes of waking, this steadies blood sugar and reduces the crash that often shows up as brain fog or irritability by mid-morning
• Cut caffeine off by 12pm, even if sleep feels fine, this protects the deep sleep stage where gut lining repair happens
• Take a 10-minute walk after your largest meal, this alone has been shown to blunt post-meal blood sugar spikes that affect mood and focus
• Rate your mood 1-10 each evening alongside a one-line note on what you ate that day, patterns usually show up by day 5 or 6

Small inputs, but the gut-brain link means they add up faster than people expect.
