Stop Spinning Your Wheels in the Gym

Are you tired of feeling frustrated, gaining and losing the same few pounds? Many people feel “sick of their life” because they can’t seem to crack the code on nutrition. The truth is, weight loss isn’t magic—it’s thermodynamics: energy in versus energy out.

TDEE stands for Total Daily Energy Expenditure. It is the total number of calories your body burns in a 24-hour period. Knowing this number is the “master key” to changing your body, whether you want to melt fat or build lean muscle

What Actually Makes Up Your TDEE?

Your daily burn isn’t just about the time you spend on the treadmill. It’s a combination of four things:

• BMR (Basal Metabolic Rate): This is the energy used just to keep you alive (breathing, heart beating) while at rest. It accounts for 60% to 70% of your daily burn!.
• NEAT (Non-Exercise Activity Thermogenesis): All the movement you do outside of the gym, like walking, cooking, or fidgeting.
• EAT (Exercise Activity Thermogenesis): The calories you burn during intentional workouts.
• TEF (Thermic Effect of Food): The energy your body uses to digest food. Protein has the highest thermic effect, burning much more energy during digestion than fats or carbs

Your Body, Your Goals

How you use your TDEE depends on what you want to achieve:

1. How Many Calories to Lose Weight?

To lose fat, you must be in a calorie deficit. A moderate approach—eating about 20% (or 500 calories) less than your TDEE—is the most sustainable way to lose roughly 1lb per week without crashing your metabolism.

2. Muscle Gain

If you want to build shape, you need a slight calorie surplus. Aim for 200–350 calories above maintenance combined with resistance training to signal your body to build muscle instead of storing fat.

3. Maintenance

Simply eat your TDEE number. This is perfect for “recalibrating” your body after a long diet phase
