45 for TDEE (total daily energy expenditure). I would assume I haven't been consuming more than 1000 calories a day, give or take.
"They cut and cut calories, see no changes, nearly starve and then give up entirely. This person asked what most people wonder but never have the courage to seek out the answer. Suppose...
Consider this fact:
As an individual who wants to lose weight and make changes thru exercise and diet, you should be striving for a larger degree of anabolism.
But what about this? "You must be in a calorie deficit to burn fat."1000 calories is beyond a deficit. It's putting your body on empty. A deficit is like being 50 cents short each day and having to get the smaller sized coffee. But reserve to empty is having to borrow money from your friend or give the business an IOU.
"Is it true that I can gradually work my way up to 2170- 2670, not change my workout, and have better results than at my current caloric intake?"Indeed this is true. Your body will have the fuel it needs for the workouts, it will be able to build up more often (anabolism) but you'll be in a slight calorie deficit meaning you are burning more calories then you are consuming but at a rate where your body feels it can let go of stored fat.
If you aren't consuming enough calories, your metabolism will slow down. The slower it gets, the less change you will see. While you want to be in a calorie deficit (defined as 10-20% below maintenance levels) you don't want to be in a starvation mode where your metabolism is so slow, you cannot lose a single pound (survival instinct).
