Every diet works and every diet doesn't work at the same time. That's because what works for someone doesn't work for somebody else.
There are many reasons why a diet can't work, but if we get on a fundamental level, it's because our metabolisms are "different".
But what does that even mean ?
[FONT=-apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Helvetica, Arial, sans-serif]Our metabolic rate, known as the "TDEE" (Total Daily Energy Expenditure) is dynamic and is made of 4 variable components. [/FONT]
BMR/RMR: this is the least amount of calories that your body requires to consume, in order to sustain its basic functions at rest. (Yes, BMR is slightly different from RMR but for the sake of simplicity, I'm putting them both in the same category.)
TEF: the Thermic Effect of Food is the amount of energy our body requires to "convert food into energy" and it's directly proportioned to the amount of food we eat, and its macronutrient composition.
TEA: Accounts for our daily activity and energy expenditure that comes from exercising.
NEAT: The last variable (and the biggest one!) accounts for the calories we burn through the day, for any activity that doesn't include exercising.
When all these variables are put together, we get our TDEE which are the calories that we need to sustain our current body weight, which of course, based on one's lean mass, diet composition, energy expenditure and lifestyle changes individual's requirements massively.
