I'm sick of delusional people who can't recognize when a kid is fat. I overheard my sister in law was talking about how her friend was so mad about something. I asked what was up and she told me "well she went to the welfare office and they commented that her seven year old son was obese. She was livid."  Me: "Um... is he?" SiL: "No, not at all."  Me: "Do you happen to have a picture of him?" Brother: "He's really solid but he isn't fat" (as he pulls out his phone to find a picture)   They find a picture that is just a head shot. His face is very round, just shy of a noticeable double chin.  Me: "Yeah, that kid is fat." Scrolling through more pictures, full pic shows the kid had a significant gut.  Brother: "No, he's all muscle."    He is FUCKING SEVEN! Seven year olds do not have significant muscle mass!   Me: "No, this kid is obese. That's not 'all muscle,' that is a bunch of fat. And it's not my opinion, it's medical fact. There's a chart with height, weight, fat% and if you fit in x column on the chart you simply have an increased risk of Type 2 diabetes, sleep apnea, cardiovascular disease, etc. The chart is not subjective and doesn't have feelings, nor is it worried about whether or not your feelings get hurt from the results. The kid is clearly obese for a seven year old and at that age it is ENTIRELY the parents fault. If they don't change what they're feeding him and how active he is, he's going to have life long health issues leading to an early grave."   Yeah, I know I held back the hate but even still I don't think what I said was well received. Who knows, maybe it got through and she'll say something to her friend.
