How to healthily lose a lot of weight without messing my metabolism?

Hello!

First, some info. I'm a woman, 29, 275lb (down 20 from 295), 5'4''. Live in Europe (if it's important). No kids had yet (if that means anything, too).

Been here for years actually, yo-yoing my way upwards instead of downwards to where I am now. 2 months ago, after an ultrasound that was initially for gastritis, I received a diagnosis of a fatty liver (and other morbid obesity-related bad blood work) and now I'm sufficiently scared into doing it the whole way this time (this is also how I stopped smoking 5 years ago, I had a health scare). I promised my gastro doctor that I will return in 6 months with 20kgs less - for starters - and a better blood work, and we'll check if my liver is better with another ultrasound. I think I'm on a good path to that right now.

I set my MFP tracker for 2lbs/week loss (because my doctor convinced me that it's nigh time to something NOW and ASAP before further medical problems arise) and I've been sticking to it, no excuses (my days are all in the green, except for one - Cristmas) and it's been really easy since I switched to whole grain carbs that keep me fuller and I finally (took me years) got into that place where you can have a sustainable, long term, but healthier diet that I actually enjoy. I haven't started on serious physical activity for now because I read on several medical sites to lose around 10% of body weight first if you are morbidly obese (my BMI now is 47) but I think I will start some light activity soon anyways. I want to do this the right way, not the fast way.

My problem is, I really like food and a life without a good, hearty meal with some nice pasta or rice is not a life for me - at least once a day. I currently eat 1500-1650 calories a day and find it ideal for not feeling hungry and still getting a good meal while losing weight. What I'm scared is that, in the long haul, I'll be having to gradually lower my calories to lose weight, and I don't want to mess my body in a way that in two years, I will have to eat, like 1300 calories, and work out for 90 minutes every day just not to gain it back. In short - currently I'm fine, but 'm worried about being in a situation like in this article on a longterm basis:
http://www.slate.com/articles/double_x/doublex/2012/11/from_obese_to_chubby_how_i_lost_the_weight_and_why_you_shouldn_t_admire.html

I think I should also add that I also read some studies (actual ones, not Cosmo ones) on morbidly obese research subject and how that after losing a drastic amount weight (100+ lbs), they had real problems keeping it off because of their effed metabolism.

My question is - what can I do to healthily lose a big amount of weight without messing up my body and metabolism? If I excercise, can I eat that back at least partially to reach 1500 calories? With a 1400 calories diet (for example), I don't want to ruin my body with burning 350 calories and having my body survive with only 1050. Also, I really like my pasta :D How do I create a life where, when I get into an at least overweight BMI area, I can eat normally and sustain it? Am I really doomed to eating 1200 calories daily just to maintain my weight?

I hope my question is not unclear and sorry for a lot of text - I'm a journalist and love writing so sometimes it gets a bit out of control :D And I'm sorry if there is a thread I didn't read - just send me in the right direction if needed :)

Welcome!

    Net your calorie goal (eat back exervise cals) and have a week at maintenance every couple of months and your metabolism will be fine.

    I wouldn't really be asking if I wasn't reading all over that you shouldn't be eating excercise cals back or maybe just a portion of it :neutral:

    if you are using the MFP calculator to determine cals, then it expects you to eat back a portion of your exercise calories

    If you are using a TDEE calculator (Scooby or similar) - then exercise calories are calculated in

    Patience is key. As long as your calorie intake is below your maintenance calories for your goal weight, you'll lose weight. Your rate of weight loss will slow (which it should anyway as you have less excess fat to lose) but you will keep losing.

    My n=1:

    I started out on MFP at ~285 pounds. I didn't like my calorie goal moving around so I experimented to find a comfortable calorie level for me, which was 1350. I didn't exercise. I stayed at 1350 all the way to a BMI of 25. At about that point, I added some walking for exercise (I now walk about 14,000 steps a day) and bumped my calories up to ~1600 to keep losing slowly.

    As for one big meal per day, I really like that as well. I get most of the volume from a whole bag of steam-in-bag veggies. I eat that with either a Lean Cuisine or a whole can of low sodium soup.
    How do I create a life where, when I get into an at least overweight BMI area, I can eat normally and sustain it? Am I really doomed to eating 1200 calories daily just to maintain my weight?
    "Normally" at your goal weight is going to be different from "normally" at your high weight because your smaller body will need fewer calories. Use your weight loss time to experiment to find a sustainable way of eating that you really like.

    How many calories you can eat at your goal weight really depends upon how much exercise you do. Not exercising may leave you pretty low on calories (maybe not as low as 1200) but exercise will give you more calories to consume. If you are physically pretty healthy, exercise is so much easier at a smaller weight that you just wouldn't believe it.

    Make sure you are eating enough, take diet breaks (where you eat at naintance) and work your way into a resistance program to build lean muscle mass.

    Lose the weight in a slow gradual manner and don't implement drastic changes.

    You cannot ruin your metabolism. Even is those extreme cases the shift in metabolism is short term and trends towards statistical normal over a matter of weeks.

    What typically happens is that people radically changes their eating habits and once their goal is achieved they return slowly back to their prior eating and exercise habits.

    This made me less worried, thank you! Exactly, I got into a scare after reading about people who lost a significant amount of weight and had problems because their metabolism was out the window as a result due to cutting back too much and working out too much - and not making up for it. I just want to plan this whole thing in a smart way so that I can manage this long term :smile:

    Excellent!

    I like to apply psychology in this and strategize in a way that our brains are wired to work. Identify a "bad" habit that inhibits your health goal and replace this with a "good" habit. Write down 5 "bad" habits you want to change - scratch off 2-5 and focus on 1. Once this habit has become fully ingrained in your normal routine then repeat this exercise.

    Our brains are not wired to simply stop doing something - why so many diets and attempts to stop smoking fail. You must replace a new activity. Think of this like the grooves in a record.

    @deannalfisher you might be able to get my point better if you read the paragraph right after the one you quoted.

    As a fellow rice and pasta fiend, I empathize!

    Maybe working out for 90 minutes a day and eating 1300 calories will be enjoyable for you once you get there.

    Haha, as someone who has two jobs, a dog and is in school, I don't have the time! But I hear you ;)

    hmm really - cause I'm 153lbs and I would probably kill someone if I only ate 1300 cal a day - I maintain on 2400ish

    Yep, 133 lb (at goal) and no way could I do 1300 cals. In the early stages of maintenance, and my body is very much 'feed me properly, dammit!'.

    OP, so long as you do this sensibly, you don't need to worry about messing up your metabolism. There is some inevitable adaptive thermogenesis that occurs when losing weight, but that can be mitigated with regular diet breaks (eating at maintenance, not a free for all).

    The issue with exercise calories is that most estimates are wildly inflated. 600 calories for 30 minutes etc.

    If you're accurately estimating calories you should eat most of them back. If you're not, then you should eat fewer of them.

    A lot of people who lose weight quickly gain it back not because of anything to do with their metabolism, but because they didn't find a sustainable way to eat. I would imagine embarrassment and feeling defeatist might make some people blame the regain on other things. You sound like you are taking a more sensible approach than a crash diet that ends in burnout and recidivism.

    I understand your fears and have read those articles about metabolic damage as well! As I can recall, the metabolic damage is really not a whole lot. Maybe just a hundred calories or so.

    But it's not something to fear, and there's no way you'd be stuck eating 1200 calories to maintain. I'm 5'7", and at 150lbs, my sedentary (aka sit on my butt all day) maintenance is 1800.

    You definitely won't have to give up any of your favourite foods, but just make sure to watch your portion sizes of them. I still eat plenty of rich dishes, rice, pasta, pizza, etc.

    I do intermittent fasting so I can enjoy nice restaurant meals with my friends and family without worrying too much about the calories. I just skip breakfast, have a light lunch, and save the majority of my calories for dinner! It's a nice strategy to keep yourself from feeling deprived.

    Anyway. It all seems scary now, but I guarantee when you reach your goal, you will forget about all these worries and feel so much better. :) Good luck.

    You are reading is "all over" because

    A) People don't understand how MFP is designed. You get a calorie deficit with zero exercise factored in.

    B.) People want to believe the numbers they read on exercise machines, or fitness websites. Take a practical approach; eat a portion of exercise calories back and ADJUST that number over time based on actual results.

    C) People assume they are logging food accurately. Hint - when people are wrong here.......is usually an under estimation of food calories. Even if the exercise calories were accurate....the numbers are still wrong.

    D) Sometimes when people do use a calculator that included exercise up front (TDEE), they forget how they set up their account here and give you wrong info based on that.

    @deannalfisher

    The fact is that not everyone will be healthy at the same number of calories. You might be great on 2400 but there are definitely people who eat 1300 and are healthy and satisfied as well. Everyone is different.

    For the record, I am one of the people who have to eat 1250 at maintenance (short, old, sedentary). I'm not there yet but I am eating 1200 to lose right now and I'm never hungry at 146 lbs.

    It's true that some shorter and sedentary women may need to eat low calorie to maintain their weight. But they are for sure in the minority. I have also helped many women with their diaries who said they were eating 1200, but once they started using a food scale and using accurate entries, they found that wasn't the case. Regardless, none of this has anything to do with the OP. 5'4" is not unusually short and she is planning to start exercising. If she makes that a priority, she won't need to eat 1200 calories, which is the point we were all trying to make. She's going to rock this and feel a million times better a year from now :grin:

    You've got some great advice on this thread. I would just add that there is time to experiment with recipes and treats and eating schedules on your weight loss journey so you can incorporate the food you love. I'm writing this from McDonald's having just finished a cheeseburger and small fries.

    Ha, for the time being this isn't possible due to my fatty liver. Because of this, I can't eat anything greasy or sweet because I get a reaction (nausea, pain). It's something about enzymes and sugars; I also got a high glucose reading on my blood test. So, until it clears (I read it's 6 months minimum, but we'll see at my check up in May), no experimenting with my favorite food in the world (which happen to be fries and pizza xD). I'm living on baked (a teaspoon of olive oil in total) and cooked food only - this is actually helping me lose the weight a lot faster than it would before. I had chocolate cake for Christmas because - darn it I can't be strict on Christmas!... And was sick the entire day afterwards :(

    I really appreciate the thoughtful and wise replies you had. I only am not sure if the same principle (just log and follow the numbers and you'll will be fine) because the body does such a huge change - with hormpnes too! I just recently did blood work on my sex hormones - when one literally halves in size with 150lbs to lose.

    I think it helps to think short term when it comes to weight loss. Long term goals are great, but worrying about the what if's a year or more down the road isn't helpful. When my doctor talked to me about my weight he recommended losing 10% of my body weight rather than telling me to go lose 140. Losing 10% can make big improvements to your health and is much easier to think about. When you hit that first mini-goal shoot for the next one. If you feel like you need a break, take one. You will get to know your body well along the way and will be able to make the adjustments you need before causing any long term damage. Relax and enjoy the journey.

    I think if you do it slowly you are less likely to damage your metabolism. The body needs time to reset and when some does a biggest loser type of diet they shock the body and it hasn’t had time to reset. I’m not sure if this is scientifically proven but data doesnsuggest that people who take longer to lose weight rather then a quick whoosh have better success. Read the success story board and you’ll find lots of great tips. I think the above poster is right. Focus on losing just 10% of your body weight right now. I bet that will help your glucose numbers at least and you can avoid insulin. You’re likely “insulin resistant” or prediabetic. So reduce your intake of carbs (not drastically maybe to 30-40%). Also if you do some weight training that will help keep up your metabolism. Just go get some soup cans or some 1-3 kg hand weights and do a total body low impact 10-20 minute weight training routine 2-4x a week. Intersperse it with whatever cardio you like. Good luck. I know going slow is tough but it’s better to start now and be somewhere even a bit better a year from now then in the same place.
