Looking at your recent weeks, I can see exactly what happened:
W13 (sick week, 23-30 March):
•Calories: 2,326 (way over target due to illness eating)
•Protein dropped to just 102g (vs 185g target)
•Training virtually stopped (15min Z1-3, 20min Z4-5)
•Sleep crashed to 7:03 vs usual 8:30+
•You gained 0.87kg fat and lost 0.98kg muscle - classic illness pattern
W14 (recovery week, 30 March onwards):
•Weight trending down (94.1kg → 93.5kg)
•Sleep recovered to 8:42
•Protein back up to 208g
•Some training resumed (53min Z1-3)
The issue: You're right to question 1,800 calories. Given that you:
1. Lost muscle during illness (nearly 1kg)
2. Are returning to weightlifting
3. Adding 2 hours of tennis today
4. Your TDEE appears higher than estimated (you were in surplus at 2,412 calories last week)
I think we should increase to 2,000-2,100 calories to support muscle recovery and your increased training load. This still maintains a reasonable deficit while prioritising muscle preservation post-illness.
Should I update your targets to 2,000 calories to better support your recovery and training?
