I weigh 190 pounds and am 5ft 5in. I'm 13 years old. I eat 1200 per day and do chores like washing dishes and vacuuming. If you could give me some tips on losing weight that would be helpful! :D
Answer
Chores DO count for calorie expenditures as they are still physical activities.
You can count 2.16/min when washing dishes (based on 130/hour) and 3.3/min when vacuuming (based on 198/hour). Time yourself and tally your calories expenditure so you can meet your weekly quota.
Do the dishes every day, like 15 minutes (32) and at the end of the week that would be about 227 calories that you would not have to exercise for (7 miles biking). You could bike a mile every day...or do the dishes. Or do both and lose weight faster!
If I spend half an hour vacuuming my house, I will surely tally those 99 calories in my weekly exercise expenditure requirement journal (3 miles biking).
I wash my windows (2.83/min), rake my leaves (4.06/min), use a blower to clean up my driveways and walkways (2.80/min), pressure wash the outside of my house (1.36/min) and clean up my yard (2.75/min) and surely time myself and if I work hours doing chores around the house, I will surely not need to âexerciseâ that day.
If I spend 4 hours pressure washing my deck, walkways, driveways, outside walls, shoes, inside and out (stinky, smelly, dirty running shoes used by extremely fit people will smell like nothing and look like new after my water pressure washer deals with those), garbage cans...I will tally those 326 calories I just burned and wonât have to exercise.
I have to wear my heart monitor when raking leaves otherwise I would get out of breath and exhausted because I would go above my THR zone. Raking my leaves is more demanding (on my heart) than jogging even if I would burn more calories while jogging.
You do not eat enough. Youâre not a 60 years old, 5'5 and 120lbs woman with a 1,200 calories BMR.
Youâre younger and bigger so you need more calories.
Your BMR is 1,724 calories (13 year old female, 5â5 and 190lbs).
You should eat enough calories to cover your Basal Metabolic Rate (BMR) or your body will adapt to a low caloric intake and lower your metabolism, making it very hard for you to use your body fat. And then, as soon as you would eventually start eating normally again, you would make body fat very easily, because you would have a lower metabolism and therefore regain all the weight you lost and keep going up, unless you exercise A LOT. Also, as youâre younger than 21, you need to eat more when having a growth spurt so you donât stunt your growth (you get ravenous).
Womenâs BMR:
655 + (4.35 x weight in pounds) + (4.7 x height in inches) - minus (4.7 x age in years)
You might already have a lower BMR if your body adapted to a lower caloric intake (takes about 3 months eating under your BMR). You need to find out if you have a lower adjusted BMR as you would gain weight on a normal BMR. Itâs what you need to eat to maintain your weight without exercising. If you exercise, you can still find out your BMR by adjusting for calorie expenditure through exercising with calorie intake...like if you exercise for 250 calories, then you would have to eat 1,974 calories (1,724 + 250) to see if youâre maintaining your weight. Of course, do not force yourself to eat more, those are daily average numbers on a weekly or monthly basis (keep a tally). Usually, if you exercise, you get hungry (low blood sugar) and need an extra snack...which you can have if youâre testing your BMR and are trying to maintain your weight. If you gain weight eating 1,724 calories and more when exercising, you need to eat less and less until you can maintain your weight...then youâll know what your lower adjusted BMR is. Then DO NOT eat under that or it will even get lower. Your body, that marvelous adaptable system, will assume that you have no access to food and will lower your metabolism. Your body is very smart, doing gazillion of operations but still has no idea about beauty criteria and that you have easy access to food, unlike 2 billions of people on our planet who donât have enough food and are happy with very low metabolisms that help them not starve so fast.
Eat enough to cover your BMR or your adjusted lower BMR. Be active (exercise and do chores) for 3,500 calories for each pound of body fat you wish to lose, taking your time (the slower the weight loss rate, the better your chance to keep it off). Half a pound of body fat loss is a perfect weekly goalâ¦1,750 calories of exercising, like 350 calories (one hour) for 5 days a week with 2 rest days. It's hard to exercise more than an hour when you cannot eat for it, since you only eat just enough to cover your BMR because you want to use your body fat.
Why don't sedans have a rear windshield wiper?
Johnny
I notice only minivans, SUV's, station wagons, and hatchbacks have rear windshield wipers, while sedans don't. Why? The snow and rain probably actually accumulates on a sedan's rear windshield because it's almost horizontal, so why don't they have a wiper? What is the need to have them on other types of cars anyway, if sedans don't?
Also, I know some sports cars like toyota Celica and the acura one have a rear windshield wiper, but the majority of sedans don't.
Answer
The reason sedan don't have rear wipers is because of aerodynamics.
The rear windows, which is like mostly vertical, doesn't get that much rain, because you're driving FORWARD. Very little water actually land on rear window. There's also rain-run-off channels on the roof of the car to "guide" the water away from the top of the roof, then out to the sides. The roof is actually curved, like the road. So most water don't even runoff to the rear windows.
And another factor is the trunk itself, which helps move air along and not circling around the rear window, trapping dirt and rain. Air flows past the roof and flies for a bit then drops onto the trunk. There's a bit of a "vacuum" near the rear window, but not enough.
Hatchbacks, with sharply raked windows, have much bigger surface area so rain can drop onto the rear window itself. There is also no 'trunk' to guide the airflow. All of the air flows right at the surface of the window, so it does need rear wipers.
SUVs/wagons with window right at the rear has nearly vertical windows, but not the trunk to guide the airflow. It has a low-pressure zone right in that area when it's moving at speed, which will "suck in" water and dirt and thus make the window very dirty. Wiper's not for the rain, but rather for the dirt (so it also has washer nozzles)
