Olie
Your AI Coach — Online
I've been stuck at 82kg for two weeks. What am I doing wrong?
Looking at your data: you've been averaging 2,180 kcal/day but your goal is 1,900. That's a 280 cal daily surplus hiding in your weekend logs. You're not in a deficit — you're in maintenance. Want me to break down where the extra calories are coming from?
Yes, and what should I change?
Your Friday dinners average +640 kcal over budget. One swap: replace the pasta bowl (780 kcal) with salmon + roasted veg (490 kcal). That single change puts you back in a 300 cal/day deficit. At your rate, you hit 80kg by June 18.
