Weight loss

I’m having a hard time losing weight after my last baby. I’m unhappy and have been a little depressed but I really need to know what everyone’s opinion on how they lost weight. I’m already starting to eat a better diet. Trying to take in more water as well. I can’t really work out at the moment but I plan to as soon as possible. I have quite a bit of back and knee problems and after my last baby my hips have seriously been killing me.
