We’ve already told you that muscle at rest burns more calories than fat. Strength training provides a more lasting boost to BMR because it alters your body’s composition by shredding fat and adding muscle.Your BMR returns back to its normal level within 15 minutes to 48 hours after working out. This boost drops dramatically following an aerobic workout. Aerobic exercise provides a temporary boost to your BMR, an effect sometimes referred to as after-burn or excess post-exercise oxygen consumption.So, it follows that the more muscle you have, the more calories you burn at rest. You can influence your BMR through exercise, spurring your body to burn more calories even when you are just lounging around – this is because muscle at rest burns more calories that fat at rest. The IIFYM BMR calculator asks for your level of physical activity for a very good reason. Your physical body does need rest to work optimally, it’s an important factor in the big scheme of any fitness plan.Īnd… you’ll get to eat foods you love and not feel hungry or deprived.
You’ll burn calories daily - some days more, some days less, and that’s okay.

Okay, this may sound counter-intuitive, but you’re going to eat the same number of calories every day – whether you work out or not. Our calculator factors in your height, weight, gender, and age, then we can plug this into our formula to create your macro blueprint. The easiest way to measure your BMR is to use the BMR calculator by IIFYM.

It’s the calories you burn, the energy you expend without lifting a finger. And again, there’s no physical activity required for this burn rate. Your BMR accounts for approximately 60 percent to 75 percent of the total calories you use daily. If you were to do nothing but lay in bed or binge-watch your favorite show, these would be the calories you’d burn – just enough to keep you alive. Basal essentially means basic - think of it as the number of calories that’s just enough to cover all your body’s basic needs. The calories used to maintain these basic bodily functions add up to your basal metabolic rate (BMR). Whether you’re talking on the phone, working at a keyboard, or just watching television, your body is burning calories to keep your heart pumping, your lungs breathing, and your organs functioning. You burn most of your daily calories with little to no conscious effort. Find out more about BMI which stands for Body Mass Index here. Not to be confused with BMI, which is another common term for discussion when it comes to weight management. The number of calories you need just for your body to function “your basal metabolic rate”, Bottom of Form. Simple definitions would be that BMR is Basal Metabolic Rate.
