TakeawayFitness trackers can be extremely useful in helping you be more mindful and intentional of your daily movement.
They can also be a great motivational tool for you to get up and move your body more often throughout the day. As we know, NEAT is a large contributor to your TDEE, so fitness trackers may benefit in helping you increase your overall NEAT. They can also be beneficial for you to be more aware of your sleep habits.
Although these devices may not 100% accurately track steps, calories burned, and sleep, they can still be helpful tools in your fitness and nutrition journey. You should simply understand the discrepancies that can occur through the collected data and not count on it being fully accurate.
Instead, focus on creating habits to help improve your overall health and happiness
