Weight Loss Calculator
Conventional wisdom states that reducing your calorie intake (or increasing the amount you burn) by 500 calories a day should lead to about 1 pound of fat loss per week.
That conventional wisdom is wrong because your metabolism is adaptive. As you eat less, your metabolism slows, throwing off common assumptions about calorie balance.
Food group targets and nutrient recommendations will not be met below 1000 calories/day. The last change you made has been reset so that you can enter a different value.
To understand why this calculator is so helpful, let’s use an example client: Vanessa. She’s 40 years old, 5′ 6″ tall, weighs 185 pounds, has a shallow level of activity at work and a moderate activity level outside of work.
Based on this information, the calculator has determined that she needs around 2,445 calories per day to maintain weight.
Let’s say Vanessa would like to lose 40 pounds sustainably over the course of the next year, without doing much additional exercise.
If you do conventional calorie math, these numbers don’t make sense.
Why this huge disparity?
As mentioned above, your metabolism adjusts as you eat less and lose weight. And conventional math doesn’t take this complex nature of human metabolism into account.
That’s why it’s important to make sure your expectations about weight loss and body change align with how your body actually works.
This calculator helps with that. It makes it easier to set appropriate behavior goals and gives you a more realistic view of what your potential progress could look like.
But here’s what it can’t do: Predict all the other factors that affect your ability to lose weight. It doesn’t take into account your unique food preferences, lifestyle, or abilities.
