Just for the sake of argument... do you give everyone who applies to college a degree? Or do you think they should actually put in the work and reach the finish line before they are considered a success? Do you think someone should get the same praise for announcing to their pub buddies they want to climb Everest as for actually climbing it? Your argument is “what if”- i can give you hundreds of examples of fatasses who started off half assed like this and gave up soon afterwards, or who persist but refuse to get qualified advice or put down the fork and thus never lose the weight. People who successfully lose weight and get back to a BMI under 25 overwhelmingly start by attacking their diet. You can’t outrun your fork, but you can post to imgur for asspats and that sweet sweet dopamine rush to make you feel like you’ve earned that giant protein shake because, hey, you’re exercising!
