Ten pounds in a week is largely water and glycogen weight; real fat loss is 1-2 lbs/week sustainable. The twenty-one tactics below support faster progress within that honest frame.

1. Calorie deficit of 500-750 kcal/day
2. Protein 1.6-2.2 g/kg
3. Two cups vegetables at lunch and dinner
4. No late eating (finish by 8 PM)
5. 2.5 L water daily
6. Sleep 7-8 hours
7. Strength train 3x/week
8. Walk 45-60 min daily
9. No alcohol
10. No processed foods
11. Limit sodium
12. Pre-meal water (500 ml)
13. Smaller plates
14. No snacks in the house
15. Protein at breakfast
16. Don't skip meals
17. Track consistency daily
18. Weigh weekly
19. Measure waist monthly
20. One accountability partner
21. Accept the rate is 1-2 lbs/week fat

21 tactics. Stack 10 for 2-3 weeks; the deficit compounds and the body adapts to the pattern. Fast weight loss in the marketing sense is mostly water rebound within two weeks. Real fat loss at sustainable pace is the only version that stays off.
