Nutritional Calculator

Are you looking for an online nutrition calculator? At Gym Food Australia, we know that an accurate basal metabolic rate calculator can help you determine your calorie requirements.
Using information about your height, weight, age, and gender, we'll identify how many calories you burn naturally. To make the most of our BMR calculator for women and men, it's helpful to learn more about what your BMR is.

How a BMR calculator for men and women works

An online nutrition calculator that provides you with your BMR is telling you how many calories your body needs in order to meet its daily requirements.

Throughout the day, your body burns calories without any effort. With a basal metabolic rate calculator, you determine how many calories you'll burn without exercising.

The benefits of using our online nutrition calculator

Overall, you burn 65 to 70 percent of your calories without trying. Once you use a BMR calculator for women or men, you can identify how many calories you need to burn to lose weight. After identifying your requirements, you can create a calorie deficit through dieting and exercise to enhance your weight loss efforts.

Alternatively, if you're interested in weight maintenance, you can use your BMR as a platform for how much you should eat to stay at the same weight. Finally, if you're looking to gain, go over your BMR.

At Gym Food Australia, we can help you use your BMR result to your advantage with our selection of products. From meal prep through to easy fat loss plans, we'll cover all of your nutritional bases.
