Can't stress this enough. I've spent the last decade trying to lose weight and failing, always yo-yoing up a little bit higher and losing confidence each time. Consistent diet changes are really freaking hard especially when you're battling other health issue. Aerobic exercise burns a hilariously tiny amount of calories for the effort and eventually it can eat away at motivation.
Setting up a home gym to lift weights and trying to eat healthier rather less has done wonders for my health. ExRx has a lot of information [1] but the gist of it is that a pound of fat burns under 5 calories a day while a pound of lean muscle burns 30 calories a day without exercise and as much as 50 calories a day for up to several days after anaerobic exercise (weight lifting). The maximum grow rate is from half a pound to a pound (for those that won the genetic lottery) of lean muscle a week so in 10 weeks its possible to add 150-300 calories to your basal metabolic rate that requires minimal maintenance compared to on-going dieting. Weight lifting doesn't require that much effort [2] or maintenance, just proper form and equipment, so it's a lot easier to permanently incorporate in a schedule a few times a week than a life long dieting change.
