Core Features

  • Gym Geek uses Smart Calorie Adjustments™ to adapt to your metabolism.
  • Your calorie goal will update every time you track your weight.
  • You can change your weight loss or weight gain goal at any time. Gym Geek will use your full tracking history to fine-tune your calorie goal.

How to track your weight

  • From the Track tab, scroll down and tap the "Track weight" button.
screenshot - The Track tab in the Gym Geek app contains a Track Weight section. Click the Track Weight button to record a new weight for that particular day.
  • Input your current weight in the same units as your target weight (pounds, kilograms or stones and pounds) and press "Save".
screenshot - In the Track Weight modal, enter your weight. The screenshot shows input in kilograms, but your current weight will match the units of your target weight, which you can change from Settings.
  • Gym Geek will now recalculate your calorie goal.
  • Gym Geek uses a statistical model to see whether you are losing weight slower or faster than expected.
  • If this is the case, it will apply a Smart Calorie Adjustment™ to your calorie goal. This means calories are either added or subtracted, with the aim of keeping your weight goal on track.
  • Review your new goal and tap "Start today" or "Start tomorrow".
screenshot - After you record a new weight, your calorie goal is recalculated and presented to you. Click Start Today or Start Tomorrow to accept your new calorie goal.
  • You can view a history of your Smart Calorie Adjustments™ from the Energy and Weight Insights section.
screenshot - The Smart Calorie Adjustment™ Insights chart shows a full history of calorie adjustments made to your calorie goal. You can compare your maintenance calories against the average person of the same age, gender, height and current weight.

Technical details

  • The number of calories your body burns each day is called your total daily energy expenditure (TDEE).
  • This number is also called your "maintenance calories" since if you eat exactly your TDEE, you will neither lose nor gain weight.
  • TDEE includes your resting energy expenditure (REE) as well as the calories you burn when digesting food and the additional calories you burn through physical activity like exercise.
  • Most calorie tracking apps use a formula like Mifflin-St Jeor to estimate your REE. Gym Geek also uses this formula to estimate your initial REE.
  • Gym Geek uses a statistical model built around the uncertainty in your REE, based on the calorie and weight data you track over time.
  • Our model combines the Mifflin-St Jeor equation with your data. In this model, the initial calorie goal is weighted by K calories and the adaptive TDEE estimate is weighted by the total number of calories tracked.
  • To improve the user experience, the data is also divided into multiple time periods, with weightings exponentially decaying by a factor γ. This ensures that the most recent user data is taken into account.
  • K and γ are chosen by Gym Geek empirically, based on real-world user data, to account for the statistical variation in the estimate.
  • The REE calculation is performed whenever you record a new weight. Any changes to your REE are called Smart Calorie Adjustments™.
