Similar adaptions occur in muscle. The extent of new muscle fiber development (hyperplasia) is debated, so there are multiples factors influencing how muscle retains some memory of past strength ability. Once you’ve reached a level of physical strength it’s easier to return to that level in the future. This has been a topic of debate in the sports world because past anabolic steroid use could therefore carry benefits…

I can't remember exactly what I was listening to, maybe some kind of NPR podcast. But the doctor was mentioning that none of the influencers influencing young people to try T and Steroids (which is rampant right now) are ever mentioning that you are on a ticking clock to infertility as soon as you start this stuff. Some people can regain their fertility but it might take years, and some people are going to be permane…

This is self-defeating and untrue. Many people, myself included, have kept weight off for decades. But you don’t get there by thinking of your new lifestyle as “dieting”. You need to learn to love eating healthy foods in a healthy amount, and getting exercise. Eventually you can get to a place where the old foods and habits are simply unappealing.

This is not untrue. Look at the long term numbers for successfully keeping weight off, 5, 10 years out. They’re abysmal.

Its because people treat it as a DIET and not THE NEW NORMAL.

When you stop a diet, you go back to eating shit. The new normal just keeps you at the same place because you get used to the fact that you don't need to eat breakfast, and a 500 calorie lunch is perfectly satiating, hell maybe a bit too much.

It is what i did. Learn to live with hunger for a while instead of going to "fix it" instantly. No idea why you are so dismissive.

the fact that you were able to live with your level of hunger does not mean that for somebody else the level of hunger is the same or is as easy to manage as it was for you. this is not helpful

It's very easy to fast for a few days once you get used to it. Your hunger is food addiction, not your body actually needing those calories.

Tell that to all the skinny endurance weekend warriors who fuel their exercise with huge amounts of sugary drinks and gummy bears. If you are curious, read about the function of GLUT4 in the membrane of skeletal muscles. Reality is more complex than memetic one-liners.

I will as soon as I see any of them gobble up a smothered burrito or Chicago pizza on their run. Do we really want to compare ultramarathon runners with couch potatoes?

It's insane how arrogant people can be about this. You have not accounted for all of the variables and that is blatantly obvious. The phenomenon is well known and there are multi-variable equations for it, many different models. One popular model is that NEET can decrease below the caloric deficit, meaning you still gain weight by becoming subconsciously lazier despite everything feeling equally difficult subjectivel…

Nutritional science is pseudo science at best. I had rather continue to believe in thermodynamics lmao

It's not about the weight, it's about the exercise. Start with something easy and establish a rule that won't ever be broken. If you break a rule once, you'll lose the fight. My rule, for example, when I started to train more: - start with 10 crunches every morning and evening - increase by 2 crunches every day - no exceptions When you are at ~2 months in, you can add weight training to it to get stronger. Additional…

Have you actually lost weight like that? I think exercise is a huge trap for weight loss. Cardio exercise makes you healthy, but it will also make you hungry. Especially if you are not used to it. Overweight people are usually already overeating. They can't deal with hunger and cravings well. If you make them do cardio, they will likely eat back whatever they burned and most likely much more. And even if they don't,…

Funnily enough, once you get decent enough I have a hard time eating after doing cardio. I need to force myself to eat something that isn't just a gatorade because my body is too busy recovering to spare any blood for my gut.

And yet it happens. A doctor in my family told the story of a patient they were treating in hospital who medically needed to lose weight, and who they found unable to get any reduction until they dropped below _200_ calories a day. Metabolism is _significantly_ more complex than CI/CO, from experience.

What is more likely: - a physics-breaking thermodynamic anomaly - a food addicted person is lying about their consumption 200 kcal a day.. yeah sure. A human body needs more than that just to breathe and pump blood. Even comatose a skinny person needs 5 times as much. Overweight people have a significantly higher metabolic base rate. Just breathing can easily be 1000kcal a day if your lungs have to move 30 kilos of u…

> Weight loss and gain is a solved problem, but self control and human behavior is not.

Semaglutide and tirzepatide address the self control and human behavior problems. They stop you from wanting to eat more.

But it is basic physics, which is in fact being violated. It's really very normal to require exceptional proof for this. Like literally any scientific study, not just an anecdote claiming magic.

Basic physics says CI/CO applies to a closed system. Show me a closed system human and then it will be applicable.

E=MC^2 is basic physics too. So eat a pea and have enough calories for the rest of your life and then some?

Well, yeah. Adipocytes multiply when you get fat. But when you lose weight, they don't apoptose, they just shrink in volume by giving up their lipid stores.

Is this true? When I looked into this issue it seemed the medical consensus is that fat cells are mostly constant throughout life, and weight gain happens through adipocyte hypertrophy.

This is interesting because about 20 or so years ago when I was super into bodybuilding, you couldn't talk about a "cycle" on a bodybuilding forum without talking about a "post cycle protocol."

I know that's different than permanent TRT but I feel like you couldn't get very far researching that stuff without understanding that you natural test production (and sperm production) would get "shut down" as soon as you started adding exogenous androgens.
