A Caloric Deficit Is Needed Over Time To Lose Weight

You must burn more calories than you consume (caloric deficit over time) in order to lose weight and burn body fat. This is the law of thermodynamics. Even if you are a "workout warrior," the law of thermodynamics still apply. You cannot eat as much as you want (or maintain a caloric surplus) and still lose weight.

Again, you must maintain a caloric deficit over time in order to lose weight. Here is an example: 1) your daily maintenance calories are 2500, 2) your caloric intake on day 1 is 2000 and 3) your caloric intake on day 2 is 3000. Over a two day period, you have not achieved a caloric deficit. Instead, you are in caloric balance. You will not lose weight over the two day period. You can expand this example to one week, one month, etc. To lose weight, you must be consistent with your eating patterns and maintain your caloric deficit. If you exercise regularly, it will be easier for you to maintain your caloric deficit.
