I have a family member who is constantly posting on social media about their weight and appearance, and has been doing so for easily a good 10+ years at this point. I am sympathetic to their struggle, and I feel bad that it affects their self esteem and whatnot, but on the other hand, if they had been putting in enough effort to lose even just 1 pound per month over the decade+ this has been happening, then they would have been able to stop posting about it by now. They are one of the most active social media users I know, so I know that they have plenty of time that they could divert towards being more active, they just simply choose not to. I can only feel so bad about that after so long.
Yup, calorie counting is where it’s at. I lost something like… 60? Pounds in the year leading up to my wedding by just counting calories, as I was too busy between working full time and going to college full time to go to the gym consistently enough to rely on that. People underestimate caloric intake and overestimate the impact of physical activity in my experience. Not to say that physical activity is not important, more so that you can overeat calories much more quickly than you can burn them off.
