How Many Calories Should I Eat Pre-Weight-Loss Surgery

BMR

Your Basal Metabolic Rate (BMR) is the foundation of your pre-surgery weight-loss plan.

When my dietitian said, “You’re eating about 1,700 calories (my BMR) a day to maintain your (heavy) weight. We need to reduce that by 500 calories daily so you’re able to lose weight during the six-month, pre-op program,” I groaned. Wow, 1,200 calories?

I didn’t want to diet.

Been there, done that.

But, I had to lose weight so I could have my gastric bypass surgery.

So, I counted calories every day** and lost about a pound a week during the six-month period.

How Many Calories Should You Eat Pre-Surgery?

As you and your medical team plan your pre-weight-loss-surgery program, your dietitian probably will calculate your basal metabolic rate (BMR) too and use it as the foundation for your eating plan.

If you don’t want to wait on the dietitian, determine your BMR now by using the calculator below.

What is BMR

The rate at which energy (calories) is used for the essential life functions is called Basal Metabolic Rate (BMR). Basal metabolism includes most of the involuntary things the human body does to support life – such as breathing, blood circulation, body temperature regulation, nervous system operations, etc., but not the extra energy needed for any additional physical activity such as gym exercise.

In other words, if you laid in bed all day doing nothing else, then you would need to eat at least the number of calories roughly equal to your BMR in order to maintain your normal body functions.

Basal metabolism consumes from 60- to 70-percent of body’s total daily calorie expenditure.

BMR calculation is based on age, weight, sex and activity level.

** The key was not just cutting calories but also eliminating specific food types from my diet, such as fats, sugars and carbs.
