Edit: Been asked for clarification. I often hear stuff like “that burger is 500 calories, it’ll take an hour to work it off”! If this is true, shouldn’t we all be slowly gaining weight over the course of our lives? I’d think that, on average, a normal person will eat more calories than they can work off.
In: Biology
we‘re not *always* taking in more than we can use. those who are, however, do gain weight eventually … quickly or slowly, it adds up. Haven’t you seen the statistics on how heavy today’s people are? Practically everyone today is a size that, just 50 years ago, would have been “the fat guy”. Watch a movie from the 70s and be amazed.
It takes a lot to be morbidly obese. Obese is actually a pretty low threshold, comparatively.
People that get that big consume 5-8 k calories a day.
Most people are just a bit overweight.
Because there are people who dont? If you take more than you put out then you 100% will gain weight. But I lost 3pounds in the past few weeks which means I had over a 9000 calorie deficit over the past few weeks.
People that do this will eventual be, can I ask clarification on your question?
For a long time I didn’t eat right and consumed a lot of junk food on a sedentary lifestyle.
I’m 5’5” and a 125 pounds. I don’t consider myself overnight tho I’m a little thicc as the kids say. So I always told myself I had a fast metabolism.
Until I found my body fat percentage is pretty high and I don’t have much muscle.
My guess is every body holds it differently. So you can’t really get a good assessment by just looking at someone.
Assuming you are very active, you need thousands of calories a day to stay active. Proathletes might consume more than 5000 calories a day.
If you live a sedentary lifestyle and eat 5000 calories a day, you will get superfat.
Because your premise is false. If you regularly consume more calories can you burn, you will gain weight. If you regularly burn more calories than you consume, you will lose weight. Every single person who consumes more calories than they burn will get fat. No person who is not fat consumes more calories than they burn. If you are not fat, you are not consuming more calories than you are burning. It’s not any more complicated than that.
Some of us poop out all excess. The unlucky ones don’t poop more when they eat more, they just gain weight. I can eat 9000 calories in a day and I won’t gain a pound, I’ll just have to use the John 7 times the next day
Because your body burns a significant number of calories just on keeping you alive. Your Basal Metabolic Rate (BMR) represents the majority of the calories your body burns every day, spent on things like keeping your heart beating, your diaphragm moving air in and out of your lungs, and maintaining your body temperature. The precise rate varies from person to person but is usually in the range of 2,000 to 3,000 calories a day. Everything else you do is added calorie burn on top of that.
So yes if you eat a 500 calorie burger, and nothing else that day, you’re actually probably going to be at an energy deficit and your body will have to burn its energy stores to keep you alive. The issue with a lot of people is that we consume far more calories than we need, and if you do that excessively, then yes you *will* likely become overweight.
Weight gain is determined by net calorie intake
Net calorie intake = Energy input – total energy expenditure
Total energy expenditure = Basal Metabolic requirement (energy you would spend just staying alive, and doing nothing else) + thermogenesis (energy spent keeping warm) + other things + work done (energy spent moving and doing things)
As you can see, your body uses up a whole lot more energy than just the energy spent moving and doing things, it’s actually the vast majority.
So your normal calorie intake is spent on all your stuff that keeps you alive. An EXTRA burger, would take an EXTRA hour to work off.
