Help, dont understand

Hi all. I'm new to calorie counting, exercising, and what not...
So on a daily basis for a month now I have been eating around 1300 calories a day, and working out burnjng 500 to 900 calories a day (as per my fitness watch). Which would make my net (I think, dont really know) 400 to 800. I have lost 9lbs in 4 weeks. But then was reading some threads from google thst says that a net of that much is very dangerous and very bad for you?
I dont understand... any insight, or tips on this weightloss stuff would be very appreciated

Also negativity, and being rude isnt necessary.

mfp is set up to eat some of your exercise calories back because your deficit is built in before exercise. its not healthy to have a big deficit and to lose weight quickly because it can cause kidney/gall stones,hair loss, loss of your period, it an mess up your hormones,cause brittle nails,you will become tired and maybe dizzy, have headaches,etc. what amount did mfp give you to eat calorie wise? if 1300 eat to that and any exercise eat back at least 50-75% back if not more and give it a several weeks to see if you are still losing weight or not. if you lost 9 lbs in 4 weeks and just began a lot of it could be water weight too. you dont say how tall you are,your age, how active you are or what you currently weigh,so its hard to gauge if `1300 is even enough even without exercise.

This is an excellent video on why you're supposed to eat exercise calories on mfp:

Mfp says to eat 1580, I do leslie sansones walk at home for working out.
What would be the point of working out if you eat back your calories burnt?
Not sounding bitchy, I genuinely dont get it lol.

because MFP uses whats called the NEAT method which means when you calculate how much you need to eat to lose your deficit is built in WITHOUT exercise. That means you should lose weight without exercise. when you exercise you make your deficit even bigger. so if mfp is set for you to lose say 2 lbs a week(1000 calorie deficit) and you are burning an additional 400-800 that makes your deficit 1400-1800 calories. now if you werent burning anything off by exercise to maintain your current weight your calories would be 2580(1580+1000)

are you with me so far? now if you were to use whats called a TDEE calculator which uses a different kind of method. those will add in your daily exercise calorie burns into the equation so you wouldnt eat those calories back that you burned because its all figured in. your calorie count would no doubt be higher too. as for leslie sansone walking how long are you doing them? because 800 calories seems highly overestimated for walking

I wouldn't say what you are doing is particularly dangerous. But how is your program making you feel? Are you feeling tired? Hungry? It does seem a little boot campish to me. I would eat back a couple of hundred calories at least.

you dont always feel tired or hungry right away though. too big of a deficit can make a big impact on health and not show the effects immediately.too big of a deficit is just as bad as not eating enough. you cannot get the proper nutrition your body needs to function properly and if not getting enough calories your body will take from fat stores,lean mass and muscle just to burn something to produce energy. If she eats 1580 and burns 400 thats 1180 and if she burns 800 thats 780 calories. definitely too little for someone of her height and weight. thats even too little for a toddler.

Losing at that rate, you're averaging about an 1100 calorie deficit a day. That level of deficit will not be sustainable much longer without health consequences. Eat a bit more and make sure you are hitting your protein macro, aiming for .8 g x goal weight assuming goal is within a healthy range.

A healthy deficit is about 500 calories per day, or 3500 per week. People with much weight to lose can safely lose 2 lbs per week. Right now, I don't think you're treading in dangerous territory since you have much weight to lose, and at your current pace you are losing just above 2 lbs per week. If you continue as is, it will eventually slow down to a 2 lb per week rate, and then less and less as you keep losing. However, after some period of time (depending on your body and how you feel - it could be weeks or months) you may start feeling fatigued/stressed from the huge calorie deficit ... this can lead to hormone unbalances, malnourishment, binge eating, etc. This is why it is suggested to eat back exercise calories. As long as you have that ~500 (suggested ballpark range here) deficit, whether you exercise or not, you should lose weight at a healthy rate.

a 1000 calorie deficit 2 lbs/week is fine(and healthy) you are supposed to NET the amount (after exercise what calories MFP gave you to lose safely. no more than 1% of her weight per week should be lost . she is stating that she is netting 400-800 calories a day which IS very dangerous BUT,with the current weight loss numbers she is eating more than she thinks(which is fine in this case) and her net is a lot smaller because if she were eating only 400-800 calories a day she would be losing a LOT of weight

calculators state her BMR is around 1800+(mfp gives her 1818 without exercise) so that is what her body needs to function calorie wise . so if she is burning 800 calories/day that makes her TDEE 2618. to lose 2 lbs she would have to eat 1000 less so 1618 calories(still below BMR). if she were netting half that she would be losing like 4lbs a week. and that is not the case shes got a deficit of about 1125 calories like maxxitt said. so yes definitely eating more than 1300 calories. its better than netting the 400-800 calories

I don't eat back my calories because I don't like the way MFP calculates it. So I calculate mine on tdeecalculator.net and set all my exercise to 1 calorie.

@Cahgetsfit

Phrasing it this way may confuse people - TDEE calculators do have you eating back exercise calories, just as an average daily amount as TDEE includes an estimate of your predicted exercise.

I do hit my macros every day.

what is your protein goal?

20

how many grams?

60 to 90g. But I also don't weigh my food I just guesstimate

So you don't know how much you're actually eating. Your workouts are a rough estimate and your intake as well. If you're full on so little food then there's any chance that you're eating a lot more, and burn less calories from your workout. I suggest you get a foodscale and weigh everything.
