Why Am I Not Losing Weight? 12 Common Reasons
If you are not losing weight, the answer is usually less dramatic than a broken metabolism. Start with tracking accuracy, weekly averages, water retention, activity changes, and whether your calorie target still matches your current body weight.
First, check whether it is a real plateau
Three days is not a plateau. One salty dinner is not a plateau. A sore training week is not a plateau. Use weekly average weights and compare at least two to four weeks.
If the average is moving down, even slowly, the plan is working. If the average is flat for several weeks, then it is time to troubleshoot.
The most common calorie leaks
Cooking oils, drinks, bites while preparing food, restaurant meals, peanut butter, and weekend portions are classic places calories disappear from the log. This is not a moral failure. It is just measurement.
For one week, weigh the easy-to-miss items. You do not have to live with a food scale forever, but a short audit can explain a stall quickly.
Movement often falls during a diet
As calories drop, many people move less without noticing. Fewer steps, more sitting, less fidgeting, shorter workouts. The calculator's original TDEE may have been right, but your actual daily burn changed.
A simple step target can help. It gives the plan an activity floor instead of leaving movement to chance.
What to change next
If tracking is honest and the weekly average is flat, reduce calories by 100 to 200 per day or add a small amount of daily movement. Hold the change for two weeks before changing again.
Big emotional edits feel productive. Small measured edits are easier to learn from.
