Worth remembering - within certain ranges obesity isn't actually correlated with poor health outcomes, the stress of trying to maintain a strict diet regime causes chronic stress damage by itself, chronic stress and environmental factors have at least as much to do with obesity as what you eat, poverty and things like food deserts or just not having the time, energy, or money to cook drives obesity, depression drives obesity, sedentary lifestyles drive obesity.
And, the most important one - considerably more than 90% of people who undertake a calorie restriction diet regain all the lost weight, or more, within 5 years.
Like don't get me wrong, i hate the way I look and would be thrilled to drop 70 pounds, but the obsession with weight is anti-scientific, actively counter-productive, and viciously individualizes societal problems. For people who aren't so heavy that it's causing serious impairment in mobility cardio and a little strength training are far more important than worrying about weight, and the evidence pretty clearly says that struggling to lose weight is worse for your health than not doing that.
