10 lbs in 2 weeks is mostly water and glycogen. Fifteen tactics that produce fast scale drop, with honest framing about what's happening.

1. Calorie deficit 500-700 kcal/day
2. Low carb reduces glycogen (water-bound)
3. Low sodium reduces retention
4. No alcohol
5. 2.5 L water daily (reduces retention)
6. No processed food
7. Protein at every meal
8. Two cups vegetables at lunch and dinner
9. No snacks after dinner
10. Sleep 7-8 hours
11. Walk 45-60 min daily
12. Smaller plates
13. Chew thoroughly
14. No eating standing up or in front of screens
15. Weigh morning of day 1 and day 14 only

Expect 6-10 lbs scale drop, ~2-3 lbs actual fat loss. Two days of normal eating = most of the water returns. For real fat loss, extend to 8-12 weeks at same inputs.
