Honestly curious, how exactly do you calculate "output" of kcal? Are you talking about estimating (probably badly) the calories "burned" by your body in order to function? Have you considered the *ahem* other way calories leave your body?
The computation is not simply that reducing your calorie intake while still exercising for the same number of minutes will cause you to lose weight. There's all kinds of other factors.
- Your body does not extract every calorie from everything you eat.
- Reducing your food intake may cause your body to burn fewer calories because it's tuned for famines.
- Eating a restricted diet may cause your body to run short of nutrients it needs to function effectively, possibly causing weight gain.
- Just like doing the same exercise every day has diminishing returns (your body will get better and better at performing the exercise while burning less energy) eating the same food every day may cause your body to get more efficient at extracting calories from it, increasing your effective calorie intake without increasing your actual food intake
- The calorie counts on food are not based on what the human body can extract from the food
Post-war America really likes simple computations, they sell well. Quantizing values and applying formulas to them makes people feel like they have control. That's why Weight Watchers managed to spread all over the country. The truth is that biological processes are rarely so simple.
The fad diets in particular push you to over-stress your body and increase cortisol levels, it might cause temporary weight loss but you'll pay for the physical damage long after the weight comes back.
