Is it normal to eat a big meal before bed and notice you lost weight in the morning?

@PinkPowerRanger of course I do, which is why I know your statement is false.

Counting calories
Have you ever wondered how many calories you burn each day? The Harris-Benedict formula can help you figure out the answer to this question. It not only helps you calculate your individual basal metabolic rate (BMR), but it also shows you your daily calorie requirements.


What is the Harris-Benedict formula?
The Harris-Benedict formula or Harris-Benedict equation was first published back in 1918. It was revisited in 1984 and again in 1990 to improve the accuracy. In its basic form, you multiply your BMR by your daily activity level to get the number of calories you need to consume each day to maintain your weight.

How do you get these numbers?

BMR
To calculate your BMR, you’ll use your sex, age, and weight. The original formulas for calculating this number are as follows, using pounds for weight, inches for height, and years for age.

66 + (6.2 x weight) + (12.7 x height) - (6.76 x age) = BMR for men
655.1 + (4.35 x weight) + (4.7 x height) - (4.7 x age) = BMR for women
A 40-year-old, 150 pound, 5 foot 6-inch-tall woman, for example, would be 655.1 + (4.35 x 150) + (4.7 x 66) - (4.7x40) = 1,429.7.

A 40-year-old, 180 pound, 6-foot-tall man would be 66 + (6.2 x 180) + (12.7 x 72) - (6.76 x 40) = 1,829.8.

Activity level
From there, you must figure out your activity level. The activity level number is defined as:

1.2: sedentary (little to no exercise)
1.375: lightly active (light exercise 1-3 days per week)
1.55: moderately active (moderate exercise 3-5 days per week)
1.725: very active (hard exercise 6-7 days per week)
1.9: extra active (very hard exercise/training or physical job)
For example, let’s say a woman is a postal worker and walks all day. Her activity level would be set to 1.9. Now let’s say a man works at a desk and walks for exercise several times a week. His activity level would be set to 1.55.

Full equation
Putting everything together, the Harris-Benedict equation is: BMR x activity level = calories to maintain weight

The 150-pound woman who is “extra active:”

1429.7 (BMR) x 1.9 (activity level) = 2,716 (calories/day to maintain current weight)
The 180-pound man who is “moderately active:”

1829.8 (BMR) x 1.55 (activity level) = 2,836 (calories/day to maintain current weight)
Online calculators
To make this whole equation even easier, there are online calculators that do the math for you.


How many calories do you burn while doing daily activities?
As you can see in the above examples, activity level has a lot to do with your results. And you may think you need to exercise hard to burn calories throughout the day. That’s true, but you also burn a good number of calories while going about your normal daily tasks. How much you’ll burn has to do with how much you weigh.

Here’s how much a 155 pound person burns doing the following tasks for 30 minutes.

Obviously googling something and then cutting and pasting is hardcore science and you deserve to graduate with a doctorate immediately for that hard work. I’m talking chemical reactions to the posters question. Why are we lighter when we wake up even when eating a big meal.. Doing those activities will burn energy.. but the energy doesn’t immediately leave your body.. those massy weight atoms don’t magically just vanish.. weigh yourself after working out and Youll not be any lighter and often heavier. Tis a chemical process like I said im simplifying because in the last hour I’ve realised more than ever that most people’s understanding of metabolism and bodies comes from newspaper headlines. the energy needs to go through a lot of conversions before it leaves your body as gas (breathing) and the water that is holding up the space for those atoms leaving. during the cycles of deep sleep is when most of the real magic and burning happens putting all that matter into cycles to remove atoms and molecules, recycle etc and much of it is breathed out and you wake up in the morning and pee a bit and step on the scale and sometimes tis like wtf I lost 5lb overnight. Sometimes the exact right amount of fat protein and precursor vitamins is exactly what’s needed to make all those processes go smoothly, and the restorative sleep to be achieved.. especially the act of not eating for many hours while sleeping enables catabolism to happen just like that. Our bodies are very complex complex systems and if just moving more was the answer it would be so so easy.. but the hormones that keep us awake and moving are often anabolic not catabolic.. muscle and energy sparing holding that energy for dear life because of threat.. or we would pass out and be eaten by a wild animal in nature. Like when you can go all day without peeing but as soon as you are relaxed and safe in your house you are busting to. Still a rudimentary description.. but the moral of the story is sleep well or you will hold onto your fat like a motherfuka @SooperSarah

@PinkPowerRanger clearly you know more than a medically reviewed scientific formula.

You said you burn most of your calories while asleep. Assume you sleep 8 hours a day. That means to burn the same as you would awake you would need to burn calories three times faster asleep than being awake. That makes sense to you?

Show me some scientific evidence that says I burn most of my calories while asleep. I would love to read it.

@Biffed Is that serious?

@SW-User Well.....
