One of the most commonly accepted formulas for calculating estimated caloric needs is the Harris Benedict equation (which factors sex, age, height, weight, and activity level) - this is the calculation I used to mention your BMR. It can be a useful tool in helping determine about where your needs may be - you can google it if you are interested whenever you decide to pick it all back up again.
Do you mean you have changed your target goals, or that you need to put the whole thing aside altogether for a while? |
