The Numbers Don’t Lie
It’s September 4th, 11 AM, exactly one week since I started Mounjaro. When I made the decision, I weighed 130kg. The day I went to the doctor, I was 129kg. Today: 126.3kg.
That’s 2.7kg (almost 6 lbs) in one week. It feels brutal - in the best way possible.
How This Week Played Out
Days 1-3 (Fri-Sun): Peak medication effect. Could barely finish one KnowEats meal per day, supplemented with a can of tuna before bed. My eating window was typically 2-3 PM for the main meal, late evening for the tuna.
Days 4-7 (Mon-Thu): As the medication wears off, I can now eat two full plates daily. Still no excessive hunger, but I have actual appetite now rather than forcing myself to eat.
Exercise routine: Monday gym session, Tuesday swimming, today swimming again, Friday planning another gym session. The activity is definitely helping.
Second Dose Tonight
Tonight at 8 PM, I take my second injection. I understand GLP-1 medications are depot drugs - they’re stored in fat tissue and released slowly. The first days have the strongest effect as your body adjusts, then it tapers until the next dose.
Even with this tapering, I haven’t returned to my old hunger levels. I could comfortably eat two plates daily now, but that’s still a massive reduction from before.
Calorie Math
My basal metabolic rate is around 2,200-2,300 calories. On training days, I can burn up to 3,000 total. Even eating two full KnowEats meals (~1,400-1,500 calories max), I’m running a deficit of 1,500-2,000 calories daily.
This level of deficit explains the rapid initial weight loss.
Side Effects Check
Stress-related: Had a work stress spike this week, which triggered my usual seborrheic dermatitis flare-up. That’s my normal stress response, not Mounjaro-related.
Medication-related:
- Increased thirst (drinking ~3 liters water daily)
- Heavy feeling if I eat too much or too greasy
- Better hydration overall
No negative side effects from the medication itself. The increased water intake actually feels beneficial.
Goal Reality Check
At this rate of 1-2kg weekly loss, I could reach my initial goal of 110kg much sooner than expected. My ultimate targets:
- First milestone: 110kg
- Ideal range: 90-100kg
I don’t want to go too low - no interest in looking gaunt. The goal is finding where I look and feel my best.
What I’ve Learned
The medication works, but you still have to be disciplined. When I feel real stomach hunger, I eat. When I don’t, I don’t force it. The appetite suppression is real, but it’s not magic - you still need to make conscious choices.
Most importantly: this doesn’t feel like traditional dieting. There’s no constant battle with willpower or food obsession. It’s just… quieter.
