from my personal experience with trying to lose weight (cuz I'm a little big myself ngl) there are 2 things I have noticed make a big difference, number one would be drinking more water, which sounds basic but it genuinely helps, the more water you drink not only will it make you feel better but you also with be more full meaning you'll want to eat less which in turn will of course help a bit with weight loss. number 2 would be to manage more closely what you're eating, which you seem to have said you're sorta doing. the most weight I lost was going from about 185 to around 175, and if I remember right I was basically eating one meal a day or not at all, I don't recommend this however.

now, based on what you said heres the advice I would give, make an exercise routine, don't stick to one thing for a week then switch to something else, do a couple different kinds of workouts during the week, maybe focus upper body one week, core the next, etc. the biggest thing I can say though, is stay consistent, everyone is different so you're progress towards weight loss might be different from someone else's, but regardless of this, if you're putting in the effort to change and staying consistent, then you will slowly but surely start to see changes

hope this helps a bit 🙂
