Ayy lmao.
First of all to everyone who believes in things like some people can't lose weight others can't gain weight bla bla... I am done discussing things with you. Scientists should study these specimens and build a car prototype based on some overweight people, that car would run forever. No need to add fuel. Hypothyroid car engines. You got it. I've heard every excuse in the book. Seen all the fat people coming out of Auschwitz? Didn't think so.
But yeah I talk with David here he seems to have his head on straight.
But I don't practice particular diets you know. I eat a little bit of everything. Like 5 eggs for breakfast, chicken breast for lunch, some potatoes fish vegetables and of course fruit and all that. I don't avoid milk products or sugar, they're just not the mainstay of my diet.
Don't eat fast food or crap like that for the most part though. And I can lose weight pretty much eating anything as long as calories are in check. But when you are in a calorie deficit it's particularly important to have a nutrient-dense diet cause food is scarce so you have to make every bit count. It's really simple. Problem with overweight people (I know because I was one) is too much reward circuits from food, they crave that dopamine high from eating tasty and sugary and salty things. Otherwise calorie requirements are pretty similar but the neurochemistry is off in those people creating an addiction for them. I am not saying it's easy for them to lose weight practically and psychologically, just physically.
While much of this is true, you're oversimplifying it. Some people are genetically more predispositioned to gain fat easily, others to be skinny and have a hard time gaining weight. That is without question (I hope).
Then there are genuine conditions which can make weight loss more difficult. Whether they be hormonal/internal issues or issues like injuries and chronic conditions making exercise more difficult. In people who are predispositioned to have a higher bodyfat % anyway these things can really cause problems. Then there are mental health issues..again, real conditions which can just make it hard for some people to even get out of bed or leave the house. It is not always black snd weight. And I say this as a guy who to the average person would be considered as very athletic looking. I have personal trained a few people in the past and I know from experience that some have it much easier than others. Hell I have it easier than most people.
Diet and exercise for the majority of people can help a lot but everybody has their own body type and set of circumstances. And back to the original point, what I have written above adds to why body shaming someone is never ok.
