If I eat 1200 calories a day and walk 30,000 steps (4 miles running + 5 miles walking ish), will I lose weight?

I suspect that's not enough calories. And are you going from no activity to 9 miles a day? Even if it's walking that's drastic. You're crash dieting and crash training at the same time. You won't sustain it.

You BMI is 24.1.

So that's okay.

Just run some more and see what happens.

BMI Categories:

Underweight = <18.5

Normal weight = 18.5–24.9

Overweight = 25–29.9

Obesity = BMI of 30 or greater

Yes, you will lose weight.

You lose weight in the kitchen. Not in the gym. Stop being such a fatty and put the fork down.

First, you are not overweight.

You will burn @ 900 "active" calories per day. Your metabolism/normal living activities will burn much more than an additional 300 calories. So you will lose weight.

Lifetime briefly had a weight loss reality series where the people on the show essentially did what you discuss. It was called "The Big Fat Wedding Walk" and obese engaged couples would go on a diet and walk 10 miles a day for 50 days straight. I think you can find it on youtube.

4 miles running + 5 miles walking isn't anywhere near 30,000 steps, but you'd loose weight on 1200 Calories a day doing almost anything.

Extremely out of shape. Need some encouragement to lose weight.

Will losing weight lower my VO2 max and make it easier to run?

That amount of calories is unhealthy and at best, you will feel starved in all your waking moments:

This! and nothing more

you'll need more calories at that activity level. don't starve yourself - it won't result in sustainable weight loss and you'd probably end up injured as well.

See where your link says html? You can erase that question mark and everything else after it and your link will work the same without being so lengthy and unwieldy. You're welcome.

Yes, you’ll lose weight. You’ll also likely lose hair from malnutrition, muscle mass when your body starts canniballizing itself because you’re not eating enough, bone mass and your period (if you’re female). You’ll likely eventually start experiencing depression, irritability, and cognitive issues like difficulty planning and remembering things. Your running and other exercise will be effected to and you’ll start getting injured.

Why? Because you’re not eating enough calories to keep an 8-year-old alive, let alone a grown adult who’s as active as you are. Up your calories several hundred and fight the urge to exercise more to compensate. You’ll still lose weight, a little slower, but that’s good because it’s more sustainable and you’re more likely to keep the weight loss off. Also, no nasty starvation side effects.

In July 2020, I walked during covid for an average 19,000 steps per day. Some running so it ended being like 11.5 miles per day (maybe 2 miles running & ~9+ miles walking).

I was 182 and lost 19 pounds that month.

I ate 2500 calories per day.

Lost 10* pounds not 19. Typo.

Yes you will lose weight. For example if you walk 12 minute miles for one hour followed by 3 nine minute miles jogging the pounds should drip off pretty quick. Its not completely healthy and i dont actually recommend it but it worked for me to drop 20lbs from 180 to 160 at 5'10"

Forget "steps", that was a gimmick made up by Fit bit.

Agreed. But it is a simple measure that’s tracked in the background that’s a good enough proxy for the general population.

pretty sure you'll die on 1200 calories + running + walking.

Without exercise you will lose weight at your size at a 1200 calorie intake. But you left out two important details 1 - Male or female and number 2 - Age. Men and women of the same body size have different calorie needs and hormones the body produces changes at different periods of your life which can affect weight loss

Yes, that kind of calorie deficit in addition to an increase in physical activity may help you quickly drop some weight, but it's generally not healthy, sustainable, or likely to provide long term results. The most probable outcome of your plan is a quick drop in weight, followed by an illness, and ultimately being in a worse position than where you started (heavier and more out-of-shape).

It would generally be better to go about it in a more healthy manner:

Don't count calories. Rather, clean up your diet. Eat higher quality foods (fresh veggies/fruits, whole grains), and cut out the processed stuff and empty calories. Cut out the grease. Especially limit empty calories from alcohol. Consume more protein.

Don't overeat. Stop eating as soon as you feel satisfied.

Hit the weight room and lift several times a week.

Definitely get the easy walks and runs in, but also do shorter more intense running/biking/elliptical/stair sessions twice a week (intervals, hills, etc.).
