Planning Around a Goal Date
If you have a specific event — a race, a wedding, or a reunion — you can reverse-engineer your required deficit:
- Calculate the weeks until your event.
- Divide total weight to lose by weeks available.
- Multiply weekly loss target by 7,700 kcal/kg to get the required weekly deficit.
- Divide by 7 for your daily deficit target.
Then verify this is a safe rate (aim for no more than 1% body weight per week) and adjust your timeline if needed.
Weight Loss Tips for Hitting a Date
- Track intake consistently — most people underestimate by 20–40%.
- Add resistance training to preserve muscle and prevent metabolic slowdown.
- Build in diet breaks (eating at maintenance for 1–2 weeks) for long timelines.
- Adjust every 4 weeks as your body changes.
