how long did it take you to lose the last 20lbs

I am 2.6 pounds from my goal of 185. I am currently at 187.6 and started at 337 back in December. It took me from July 6th until today to lose 20 pounds.

I eat 1300 calories a day. I have a pretty big deficit since I am 6'5. I don't exercise because I have a neurological disease and am disabled, however I will be doing some sort of resistance training when I hit maintenance.

You must have lost so much muscle. It's sad.

Way to be negative! The man has lost an incredible 150 lbs in 9 months, that's a little over 4 lbs/week. I say WELL DONE!

Also, loss of lean mass is normal to a certain degree, I believe 20-25% of weight loss being lean mass, is considered a normal range. You don't know what kind of diet he was on, some well crafted low calorie diets can have adequate protein and nutrition to limit loss of lean mass. But some WILL be lost. It is NORMAL.

The most important thing he has achieved is reducing his risk of obesity related conditions. That, far outweighs any concerns about lean mass loss. He already said he'll be starting resistance training when he gets to maintenance. So, he'll be rebuilding some of his lost muscle or strengthening his current muscle mass and he's in a much better place to be doing this now that he's lighter.

It's an incredible loss but unfortunately at a somewhat dangerous rate and raises serious concerns. Resistance training should be commenced at the start of the weight loss programme to preserve as much LBM as possible as you lose weight, clearly adapted for morbidly obese

Even medically supervised VLCD are necessarily short term

There are many studies to this affect: see risk of Gallstones in morbidly Obese and rapid weight loss (IIRC over 3.3 lbs a week = 77% risk , Leptin issues and hormonal imbalance with rapid weight loss and more ...

This is an excellent post which puts it in consumer friendly speak by @Faithful_Chosen in response to do I eat back exercise calories

It's long, but consumer friendly

Now, especially newbies have a tendency to up the cardio and decrease the food to make a bigger deficit, assuming they will lose faster--and they might! I am not gonna sit here and say that you won't lose more. It's probably not going to show up on the scale due to water weight, but they will lose more. The question is: at what price? And what are they losing?

The MyFitnessPal method (built in deficit based on your numbers, especially plus purposeful exercise) is designed to steadily lose fat and preserving as much muscle as possible. You see, there is a (science proven) limit to how much fat a body can convert into usable energy during any period of time. If you go over that limit, it turns to muscle for fuel instead. You will always get a little bit of muscle tissue loss when eating at a deficit, but if you undereat and up the cardio (or even strength training!) like I see a lot of people on here do, you are forcing your body to canibalize its muscle tissue on top of the max level of fat it can burn. Not to mention that meeting your macro and micro nutrient goals with this method is virtually impossible, creating massive hormone imbalances (leptine, for example) and vitamins and mineral deficits.

The long term effects of crash dieting and deprivation dieting (which is basically what happens when you become one of the people who net in the low hundreds to negatives day after day for an extended period of time) can be really severe. Basically, you are systematically starving yourself, after all. The results tend to be this (one example, hypothetical you):

- your body burns fat, then muscle tissue to sustain itself. You become weaker and sore. You also start having cravings because your brain is sending out warning signs: 'I am starving! Feed me!'. So, you either binge and up your overall net a little, or you persevere and pat yourself on the back for a job well done! You wanted lots of fatty food, but you fed it a celery stick instead. Sadly, your whole timeline congratulates you on your willpower. You start to wonder, though, why your willpower is not being rewarded! The scale doesn't budge! You fail to realize it's because of water weight due to too much exercise and the body's inability to recover due to a lack of nurishment. The solution is often to eat even less and work out even more to get the scale to move.

- the body is further unable to sustain. It changed the body's chemistry to preserve all it can--after all, it needs to protect vital organs from becoming affected and keep you going so you can hunt and gather for food! At this stage, the body becomes its own worst enemy: it no longer tells you you are starving so you can make a last ditch effort to get food. You think you are fine on 1000 calories a day, burning 1200, because your body shows no signs of hunger anymore, but basically, the little neutrients you are providing your body with get sucked towards your vital organs, leaving nothing for the rest. You become more tired, and cranky, and your muscles no longer recover from all the stress you put them through working out. As a result, they break down even faster and hold on to even more water to prevent that breakdown from affecting your ability to throw a spear at a prey animal (hey, I can't help it your body still thinks we are living in caves!). The scale drops oh so slowly--if at all--but meanwhile you do see you are slimming down! Your measurements are less! MyFitnessPal celebrates! 'Hurray! The weight must come off in a 'woosh' soon now! Keep doing what you are doing!'. Note that (thankfully) many people drop out at this stage. The psychological burden becomes too great, they feel *kitten*, and life isn't fun anymore. They stop dieting, start binging, and gain even more weight. The jojo'ing has begun.

- you keep doing what you were doing. We are a few months in now. You develop headaches, fatigue, and you start finding more and more hair on your pillow in the morning. In fact, you start finding hair everywhere. You also get hungry again, not in a way that makes you binge but a sort of steady nagging: a gentle reminder that time is running out. Fail to meet it (MyFitnessPal people pat your back when you tell them you went to bed early instead of having more food) and slowly, your body gives up its protective hold on more systems. You can survive without full function to certain organs, so your body throws them to the wolves: nutrients go towards your brain, heart, and lungs. Pretty much all other organs start running at half capacity. You hold on to more toxins, which start chipping away at your system, and your ability to process food (get nutrients out of them) suffers greatly, so you are truly starving now. This is the point where the weight starts coming off, and pretty quickly, too, usually. A big whoosh! (MyFitnessPal people cheer in the distance). What you are really seeing is your body giving up on protecting muscle tissue completely: the water weight falls away, showing you that you actually did lose a lot of fat and muscle tissue. More cheering! It must be working! Keep at it! Work harder! Eat less!

- now you are in serious *kitten*! Your organs are not keeping up, your muscles are breaking down, and the body has to start looking elsewhere for fuel: your organs and the more vital muscles, including your heart. At this point, your nails will become brittle and start falling out. Your hair falls out. Your period stops. You experience bouts of nausea and muscle weakness. You might find yourself pulling into a run and suddenly blacking out. You still function, but on the inside you are shutting down.

From here on out, it all depends on if you start eating again and stop exercising or not. If you don't, you can end up killing yourself. If you do, it is a long road to recovery, sometimes lasting years and it sometimes includes permanent damage to the function of certain organs, especially the liver and kidneys. Worst of all, this entire crash diet hasn't taught you how to sustain weight loss, so as soon as you crash and burn, the weight flies back on! And trust me, it takes a fraction of the time it took to lose it to gain it back.

I am not saying this to frighten you (well, I am a little), but as a nurse, you should be aware of the ramifications of crash dieting. Those of us that do realize the effects therefor recommend you lose weight slowly, at a sustainable rate that gives you the best ratio of fat loss vs. muscle loss. Stick to your MyFitnessPal calculated net, take the time, eat back your true exercise calories (which is probably 50 to 75 percent of your machine or database given calories), and learn how to eat (and what to eat) for weight loss you can maintain for years to come. It might not go as fast, but you will be able to see it on the scale, and best of all, it will be safe. That is my very long winded answer to 'why' you should eat back exercise calories.
