If you’ve noticed that your TDEE (Total Daily Energy Expenditure) calculation in Zolt has stopped updating and shows a “HOLDING” status, don’t worry – this is by design and happens for a specific reason. This article will help you understand why your TDEE might not be updating and what you can do to get it back on track.

Quick Fix Guide
When your TDEE isn’t updating, your app is showing you a “HOLDING” status in the TDEE Calculation Status card. Here’s what you need to do to get it updating again:
The Data Requirements:
For your TDEE to update properly, you need:
- At least 2 weight entries per week for both the previous and current week
- At least 3 calorie entries per week for both the previous and current week
How to Get Your TDEE Updating Again:
- Check your data: Open the TDEE Calculation Status card and expand it to see which data points you’re missing
- Log your weight: Ensure you’ve recorded your weight at least twice each week
- Log your calories: Make sure you’ve tracked your food intake for at least three days each week
- Be consistent: Maintain this pattern for two consecutive weeks
Once you meet these minimum thresholds, your TDEE will switch from “HOLDING” to “UPDATING” and begin providing you with accurate, dynamic energy expenditure calculations again.
Why Isn’t Zolt Calculating My TDEE Right Away?
You might be wondering: “Why can’t Zolt just calculate my TDEE based on today’s data?”
The answer lies in the science of metabolism and how your body actually works. Your TDEE isn’t something that can be accurately measured in a single day or even a few days. It requires observing trends in your weight and energy intake over time.

Understanding Weight Fluctuations
Your body weight naturally fluctuates day by day – sometimes by several pounds – due to:
- Water retention: Varying by 2-5 pounds based on hydration, sodium intake, and carbohydrate consumption
- Food volume: The actual weight of food and waste in your digestive system
- Hormonal changes: Particularly relevant for those who menstruate
- Glycogen storage: Carbohydrates stored in muscles with water
By requiring at least two weight measurements per week, Zolt can see through these daily fluctuations to detect meaningful trends in your actual body mass. One measurement can be misleading; multiple data points reveal the truth.
Caloric Intake Patterns
Similarly, your daily caloric intake varies significantly throughout the week:
- Weekends often involve different eating patterns than weekdays
- Special events, dining out, or social gatherings create outlier days
- Some people intentionally cycle their calories (eating less on some days, more on others)
Requiring at least three calorie entries per week ensures Zolt captures a representative sample of your actual energy intake, not just an unusual day.
The Two-Week Comparison
Zolt’s algorithm uses a comparative approach between weeks. This is crucial because:
- It establishes if you’re in energy balance, surplus, or deficit
- It detects changes in your metabolic rate based on weight trends relative to intake
- It neutralizes the impact of any single unusual day or measurement error
This is why both the previous and current week need to meet the data thresholds. By comparing two seven-day periods, Zolt can calculate a truly personalized and accurate TDEE that reflects your unique metabolism.
Why This Matters For Your Results
When your TDEE is in “HOLDING” mode, it doesn’t mean Zolt is broken – it means the app is waiting for sufficient data to provide you with an accurate calculation rather than a potentially misleading estimate.
An inaccurate TDEE could lead to:
- Setting calorie targets that don’t align with your goals
- Unexplained weight changes despite “hitting your numbers”
- Frustration and confusion about why your plan isn’t working
By waiting for enough data points, Zolt ensures your TDEE calculation is robust, reliable, and truly personalized to your metabolism.

Beyond the Minimum: Optimal Tracking
While the minimum thresholds will get your TDEE updating again, optimal results come from:
- Daily weight measurements: Ideally taken at the same time each morning
- Complete calorie tracking: Logging your intake every day provides the most accurate calculation
- Long-term consistency: The longer you track, the more accurate your TDEE becomes (4+ weeks provides the best results)
How Zolt’s TDEE Connects to Your Overall Health
Your TDEE calculation doesn’t exist in isolation – it’s connected to many other aspects of your health that Zolt tracks:
- Recovery: Your energy balance affects your recovery score, especially during intense training
- Activity: Understanding your energy expenditure helps optimize your activity levels
- Sleep: Your nutrition and energy balance can impact your sleep quality and consistency
Conclusion
Your TDEE not updating in Zolt isn’t a glitch. It’s a feature designed to make sure you receive accurate, reliable information for your weight goals. By understanding the data requirements and the science behind them, you can make sure your TDEE stays in “UPDATING” mode.
Remember: Consistent tracking leads to accurate TDEE calculations, which leads to better results for your weight goals overall.
