I mean, it is science, but okay—when I lose weight, it's because I consume less than I need. Exercise will help with this.
I've been out for three days, eating out each meal and drinking a few pints along the way while not doing anything manual. Guess what? I'm three pounds heavier.
I'm not saying people don't have issues with their relationship with food, but the simple fact is that in 99.9% (made up figure) of cases, people eat less, move more, and lose weight.
Weight-loss drugs don't 'melt' fat; they make you feel full, so you eat less. It's like a temporary stapled stomach. or like drinking plenty of water so you feel full.
The problem with temporary solutions like this is once you lose your weight many people start back on their normal lifestyle and put the weight back on, starting the cycle again.
When people (and I'm not picking anyone out who has posted here as I've skimmed the posts) can point out their issues with weight gain but then seem to want it validated by a condition or excuse for being overweight, then that's fine. Feed yourself that information if it makes you feel better, but unless you have a medical reason, such as an underactive thyroid or Cushing's syndrome, then it's likely down to diet and exercise.
Like many things in life, it's easier said than done; we all have our hang-ups. And I speak from experience as someone in the obese category at the moment, but also someone who has run a marathon and been 25kg less than I am today.
