Hi guys, I just have an important question… Is it ok to start Keto for weight loss without even knowing your body weight to begin with??? I am asking this because I have not weighed myself for 2 years (since I was slim) I was extremely obsessed and felt terrible if the scale didn’t go down everyday. Since then I have gained a LOT of weight, (I know just from looking in the mirror and my clothing size going up) and I am literally petrified to get on a scale. Yet at the same time, how do I properly track my macros?? Also, I don’t want a scale to discourage me if it dosent go down (as I’ve heard you can lose fat without the number coming down constantly). I was a very bad anorexic who was too weak to walk 3 years ago, so the scale and I are huge enemy’s. Please, if anyone has done keto without knowing their weight and still gotten slim, or any advice is great. It’s annoying because in all the carb count apps, they ask for your weight and i have to guess. Ive always been body dismorpic so i dont know whether my guess is too high or too low. 
Weighing myself on keto?
I started by using the scale, but I don’t use the scale anymore. Instead, I use pants sizes, how my pants fit, etc. The scale does not consider muscle mass, and I can easily gain or lose 5+ pounds if I’m fasting. That means any “signal” is buried in a lot of “noise”.
I’ve lost over 50 pounds and gained muscle, but I haven’t gotten “slim”.
You can do Keto without weighing. It’s more of a psychological thing more than anything for me. I don’t weight every day because I’m not obsessed with it. It can be used as a progress monitor early on for some, but after a while you will hit stalls regardless of how you eat so that’s one reason not to become obsessed with it.
You can go off of clothing fit, maybe body measurements, or even get you some keto strips for monitoring. By no means is a scale necessary to become healthy.
Of course it’s fine to lose fat if you need that. I owned no scale when I started to lose fat (on low-carb but it doesn’t matter). Even if I could never weigh myself, it doesn’t matter as I want a slim body, not some number.
You have a problem with scales so I guess you shouldn’t weigh yourself. I have zero problem with seeing a way bigger number on it sometimes so I weigh myself whenever I fancy it (but I see the same number, usually so it is pretty useless).
You feel and see if you lose some anyway. My pants are even better than my scale… I just can’t measure my waist, I lack the skill. I am very soft there so I get various numbers at the same time. So, my just-fitting pants. Those are good.
Reading several of your comments, it seems you shouldn’t even bother with macros (unless if you are afraid you will seriously undereat or don’t get enough protein or something. even so, you don’t need to do it for long, you see how much food should be right and eat a bit similarly every day, maybe this would be okay).
Yeah, the apps ask for your weight. I am sure you have some vague idea about it. The apps has a way more vague idea about your energy need… Don’t eat according to them. I never did that, I would have starved, calculators with their tiny numbers and me, we don’t mix well.
First, do keto, get used to it, enjoy it if you can… Give it a chance to solve your problems without extra effort with macros and calories. Maybe you will need to change something later but first, don’t overcomplicate this. If you are hungry, eat. And if you need a low number for calories, take a guess or ask us. I saw you write about 750 kcals or something. That’s starving for very nearly everyone.
1500-2000 sounds better but I don’t know your stats or the speed of metabolism. I can’t. Eat if you are hungry, at least adequate protein and if it’s, like 1000 kcal, try to eat more as it’s way too little… Sadly, some people easily undereat on keto so looking at some numbers may be useful sometimes even if it causes some stress 
. But if numbers cause very big problems, maybe just eat the way you feel right and if you lose fat too quickly or get weak or cold or something, you know it’s not enough…? I stop guessing things now, I’d love to help but it’s very individual…
Just focus on eating less than 20g net carbs a day, don’t worry about the fat vs protein ratio. You don’t need to weigh yourself - just base it on how you feel, how clothes fit, etc 
Thanks Beccs I’ve decided not to get a scale. I personally think it would be very damaging for me with my history. Thanks 
I’d guess a start weigh-in would be useful. That way, over time you don’t have to keep guestimating incorrectly how much you’ve lost since starting. Guestimates tend towards the rosy what I wish it was.
That said, keeping track of weight loss over time is useful if for nothing else than to avoid those rosy guestimates. But as many point out, this can get obsessive. It’s the long term trend that matters not the short term and/or daily ups/downs stalls, etc. Even if initially your primary goal is weight/fat loss, when you start keto a lot of other stuff goes on at the same time. Much of it works to heal damage and restore normal functioning of many related metabolic processes. Sometimes that will take precedence. Sometimes you might add lean mass that offsets fat loss for zero net change. Simple scale weigh-in will not show that.
Add: as @PetaMarie says below, a tape measure (and knowing how to use it) plus a caliper can yield better info about fat loss than a scale.
Wow, Thank you. I feel better about not getting a scale now. My face is thinner and my fingers (probably waterweight as its only day 7) but its a start.
I used a tape measure when I started and remeasured all the parts once a month. In the meantime, my bras and undies kept me in the know about losses. It’s easier to notice a difference with things that are tight or well fitted. I didn’t get a scale until a good 6 months into keto (to avoid obsessive behavior.) Now I weigh weekly, on Sunday. If I happen to get on it any other day, I don’t have emotions about it. It’s only ONE measurement out of all of the other things you might notice (better sleep, clearer skin, more energy, better appetite control, less colds, etc.)
I did what you advised and got a scale. I hated stepping on the damn thing but I needed to know my starting weight. It sucks. But now I’m going to forget about the thing and do a weigh in once a month or even more. I don’t want it to discourage me or control me like it used to. So I faced a massive fear by doing that.
I try to only weigh myself once a week (Sunday’s around noon before I have eaten or drank anything, not even water). I figure if I do the same time before any foods or liquids in me, it gives me a more accurate reading for the week =).
Yes I agree now. I did weigh myself and it sucked but i had to face the truth. Heaviest ive ever been. Apart from the last two years I’ve always been slim or normal so it’s really shit. At least now I know where I’m at. I’m avoiding the damn thing for a while. Maybe weigh myself every two weeks. When I was 115 pounds I loved the scale…Not so much now. I’ve got a lot to lose. Am very committed to getting healthy again.
I guess because I’ve had anorexia in the past, I feel like I’m a failure if it’s a high number. I’m trying to tell myself it’s just a number.
Thankyou. Yes I think it stems from my family being nicer to me if I’m thin and mean if I gained weight. Am trying to heal
