there is such a thing as adaptive thermogenesis, but it doesn't fuck up your metabolism. it's a slowing down that occurs when you eat a lot less, but if you ever began to eat normally again, your metabolism would go back to normal within days
>>35783105 You are bullshit. Famine response has been a well known fact in the fitness community for years. Wonder why professional bodybuilders never cut with extreme deficits?
>>35783066 OP, you are just gonna lose all your muscle and little to no fat, and you are putting your health at serious danger. Cut with something more healthy, like 500kcal deficit of yout BMR, and do more cardio if you need to lose more fat.
>>35783066 Your body knot takes so much of your deficit from body fat. For example if you're normal sized your body will only take ~500 CALS of the deficit from fat, and the rest will come from body muscle, internal organs etc. This is why anorexics have hair falling out, Laguna, dry skin, nails can't grow, and internal body organ failure- the body will literally eat itself alive first. This is why you don't want a deficit more than about 500 (if your not obese), you will d up losing more muscle than fat. You expect the human body to magically take 100% of a 1000+Cal deficit from just your body fat? We wouldn't be alive if that were the case. Your body compensates for you
why do you people act like fat has no purpose? why on earth would a body consume its own essential organs before consuming the thing WHOSE SOLE PURPOSE is to be consumed when you are at a caloric deficit?
it doesn't make any sense, and it's demonstrably false
>>35783592 >n 1965, a severely obese man starved himself and survived off his body fat for 1 year and 17 days. He was continually monitored by University of Dundee medical staff in Scotland who only fed him yeast, multi-vitamins and occasionally potassium for his heart. They kept their eye on his condition and took routine blood tests. After all was said and done, he had dropped from 456 pounds to 180 pounds. He was weighed again 5 years later and had only put on 15 pounds.
>>35783621 >its bullshit that your body wants to keep energy reserves and warmth How stupid are you? You can read about the effects of anorexia on Google for real life references of what happens to your body. By your logic anorexia wouldn't exist.
>>35783631 How is this relevant? I specifically mentioned multiple times in the post that that would only apply to normal sized, non obese people. Obese people will have much higher tolerances of calorie deficit because their bodies have a much higher % to give >what is reading comprehension
>>35783713 By definition you cannot be anorexic and fat at the same time, but no that doesn't mean people don't go from fat to anorexic. I personally did. I personally have experienced what happen when you eat at a 1000+ Cal deficit and its not pretty.
>>35783780 sure, you can go from fat to anorexic, and I agree that you shouldn't eat way below your TDEE if you're not fat. But if you have weight to lose (the only reason you should diet anyway) you're not going to consume your organs.
And I have experience in eating at a 1000 cal deficit too; I was just never anorexic
and the results were brilliant. I lost a whole bunch of weight, and my hair remains firmly atop my head
>>35783733 >the lower the bodyfat the healthier The internal organs aren't prioritized over your body canabalizing its muscle tissue. It moves onto internal organ damage once its starts to exhaust other resources such as said muscle tissue and fat. Your body REQUIRES a certain level of bf% to survive, so it makes no sense that it would choose to completely take away only all fat until its 0%. Females in particular need to maintain at least 15-20% Bf to be able to reproduce. I know you guys think fat is "icky" , but you do require some level of it to survive.
>>35783816 That post specifically addresses only normal sized people within a healthy bmi range, not obese people. You can cause bodily damage without being technically underweight. The lowest I got was 125 at 5'7 which is still about 19-20 bmi- yet because my deficit was so high for so long my body had destroyed a lot of muscle and simple things like skin hair and nails don't grow at all or grow out already damaged. Keeping warm was quite difficult as well. Point being you don't have to be medically underweight for your body to start eating itself. But if you're quite fat this is likely not a problem( as stated originally)
>>35783733 being alive means you have a chance to sexually reproduce. That's all your body really cares about, when push come to shove. Your hair, teeth, skin, stomach, and other internal organs will start to be broken down before every gram of fat is used because your body needs fat to stay alive, and to reproduce. Internal organs can be sacrificed without death or no chance of reproduction, but not literally all of your fat. I was threatened with hospitalization because of danger to organ failure, yet I still had small amounts of fat in my body. If you've never been there then good for you, but stfu about stuff you have no experience with.
>>35783876 I started off at 15x lbs, very much diet worthy. It took me about a month or two before my body started destroying muscle etc. Its not like this isn't a common occurrence. People often end up losing just as much muscle weight as fat when they go on diets
>>35783066 Starvation mode is kind of bullshit kind of not. Eating a low calorie diet will lower your metabolism as your body gets used to it. Best thing to do is full on fasting. Apparently when you're fasting your body does not lower metabolism the way it does on an extremely restricted calorie diet. And your body only goes into starvation mode once you're literally starving. As long as you have excess body fat you are not starving and your body won't react as if you are.
Anyway, best way to cut is a sort of intermittent fasting. Eat regular, lowish calories on days you eat but do like 3-4 days of water fasting a week. You can split it up or do it all in one go, either works, but keep in mind the benefits of fasting increase the longer you go. So like eat regularly fri-sat-sun, then eat nothing mon-thur. Even if you eat 2500 cal/day on those three days that' still ~1070 cal/day average, but without the negatives of a very low calorie diet and your body adapting to it.
You will not lose muscle. At my peak weight I was 186 pounds (5'6" and I was 130 before I started bulking, but I obviously gained a shitload of fat too). That was 2 years ago. I haven't done weightlifting since then and have done many diets and even fasts. I am now 155 at about 15% body fat. I've lost at most 5-10 pounds of muscle after 2 years and that's to be expected when you stop hitting the gym completely after a huge bulk.
And I'm glad for that. I've been paranoid as I've been sidelined from the gym for about 2 months, but I've still been eating at a small deficit. I don't want to get too much weaker (I'm weak af as it is)
>>35783966 OP here, fuck that shit. I'm not aiming for auschwitz refugee of the year -award, just trying to cut to maybe sub 15% BF. Obviously the body needs some fat, but don't tell me my spleen and second kidney are gonna stop functioning because I cut a bit too fast inside the healthy bodyfat ranges.
>>35784057 M8, you can, if you want, take that comment out of its context (the context is that we are addressing OP and his condition).
If you do, then fine. I said that it doesn't want to burn its organs before fat. I didn't explicitly state "unless you have too little body fat", because given the context, I felt like I didn't have to give every single caveat.
Again, you can, if you'd like, think that I meant that there is no circumstance under which your body would do that. I didn't mean that, but if it makes you feel better, I don't mind if you think that I did.
>>35784089 The context was the post that you responded to, and the previous one's you'd responded to. You didn't provide any caveats, at all. You said it was stupid, and that people are dumb for believing it. You said it was demonstrably false. People provided arguments that contradicted your point, and you didn't change anything about your position. That's when you could have provided ONE caveat. But you didn't. Maybe if you don't want people to take your shit out of context, then you should think before you start writing.
>>35784278 You admitted anorexia exists, yes, but you vehemently denied physiological symptoms of anorexia with little explanation other than "it's stupid". I don't need to feel right, but you're refusing to admit that you were being vague as fuck.
And because it's related physiologically holy shit. We're talking about denying people calories. A lot of calories. That's relevant. If OP cut on 1100 calories and dropped well below his current weight that shit would start happening.
>>35784740 >dietician What the hell is that? I would rather not listen to a person who has something to sell, especially when it's probable he was just 5 years ago recommending low fat diet and pushing fat-free products or something.
>>35784757 does this fucking retard ACTUALLY think you need to eat your BMR or you'll drop dead from starvation? jesus christ this retard is retarded as FUCK
Your body is more than capable of taking most of its calorie requirements from fat if you're above 5% BF, and all of them if you're above 10% BF
look at Key Semi-starvation study, you cock gobbling retard, even under a diet nearly bereft of essential fats & protein, the subjects STILL did not start seriously metabolizing muscle until they were around 5% BF
>>35784955 >Each pound of fat can provide up to 31 calories per day... >only reading the abstract Shiggy. >if your deficit is higher than that then the energy has to come from muscle. This is not a conclusion of the source you provided.
