Weight / Fat loss

Everyone has a Basic Metabolic Rate (BMR) a certain energy requirement for staying alive and functional. Add to that a active lifestyle/job and excercise calories to give a Total Daily Energy Expenditure (TDEE).

So long as your calories consumed is less than your TDEE your going to loose weight. Either that or you are the free energy experiment that all scientists are trying to find.

So, your tracking calories and failing.

1. Your supposed deficit isn't as big as you think! You've got plenty of energy, don't feel hungry and you miss logging wee treats here and there. Or an hour in the gym whilst mostly chatting to your friend doesn't equal the 500 calories you think it should.

2. The other extreme is your deficit is too big and your often hungry or crave stuff whilst smashing out loads of cardio. If you have the willpower to tough it out, your going to loose weight fast to begin with. That is untill your body intervenes and protects itself from your self induced famine. It slows down its metabolism which lowers your BMR. That leaves you not loosing any more weight but still eating fuck all and it's either a downward spiral of eating even less or your probably going to put weight back on as your intake becomes greater than your TDEE.

Somewhere in the middle there's a window off 100 to ~600 calorie deficit that will work. So 100 calories isn't much, but it's still progress of 11grams per day. 400-500 is comfortable for me.
