TDEE Tracking Checklist: Your First 30 Days

Tips

Small moves that make the checklist easier to finish

Daily weight fluctuates 1-2 kg from water, sodium, and food volume. Never make decisions based on a single weigh-in — always use the 7-day average.
If the scale isn't moving but your calculated deficit says it should be, under-reported intake is the first thing to check. In the classic NEJM study of diet-resistant obese subjects, self-reported food intake was 47% below measured intake while activity was over-reported by 51%.
Constancy of conditions matters more than precision. Weigh at the same time, on the same scale, in the same clothes (or lack thereof) every day.
