Dietitian warns fitness wearables and AI food tracking can drive unhealthy habits
What happened
A sports dietitian told Tom's Guide that people are taking fitness tracker data as gospel and using AI tools to photograph food for calorie analysis. The concern is that both wearable companion apps and AI food-logging tools can promote unhealthy eating behaviors rather than support genuine wellness.
Why it matters
Fitness trackers and AI food scanners give you numbers, but those numbers are estimates, not facts. Treating them as absolute truth can lead to obsessive tracking, anxiety around eating, and decisions that hurt your health instead of helping it. A qualified dietitian can give you context that no device can.
Who's doing it
A sports nutritionist interviewed by Tom's Guide flagged the risks of over-relying on AI and wearables for fitness and eating decisions. The article also references Google's Fitbit Edge tracker as part of the current wearable landscape.
Try it
- Open your fitness tracker app, such as Fitbit, and find your daily calorie burn or step count. Write down the number, then remind yourself it is an estimate that can be off by 10 to 20 percent.
- If you use an AI food-logging app that analyzes photos of meals, log one meal as you normally would, then compare the calorie result to the USDA FoodData Central database for the same foods. Note the difference.
- Pick one day this week to track nothing. Eat normally, pay attention to hunger and fullness, and notice whether your relationship with food feels different without the numbers.

The Professor fact check
The article's own test suggests calorie estimates can be off by 10 to 20 percent. A photograph-based AI system compounds that error with portion-size guessing. These are statistical models, not measurements.
Karen what's the catch
So I'm handing my food photos to some app and it's giving me WRONG numbers that make me eat WORSE? Who is storing those pictures and why am I not getting a dietitian for free?
