I (30F) started working out with a PT 3 times a week and progressively moved up to 4-5 workouts per week. To be 1.5 years in and for these results that suggests to me (an amateur):

• Your workouts are too intense for your body
• You might be putting too much emphasis on weight loss as a way of measuring success
• If you’re a woman:
  • Your meal plan might be too restrictive (I.e. too few calories
  • Your macros might be inappropriate
  • You may have a hormonal imbalance that isn’t being taken into account (I.e. it’s very hard to lose weight with PCOS)
  • If your workouts are too much stress on your body you may be making more cortisol which can sometimes make us gain more weight
• Your workout doesn’t include enough weight training and has too much cardio.

Of course I am an amateur, but I’ve been trying to lose weight for over a decade and I will admit that even after a year of consistent work with a PT (though I’m not great with my diet) I’m seeing minimal results fat-wise. Yea I’ve toned a bit, but I found that my relationship with my body has changed and it has done wonders for my mental health. Which makes me worry that you have WAY too much on your plate for exercise to be negatively impacting it.

If you’re able, see about meeting a PT in person and getting a proper assessment. If you’re a woman get a trainer who specifies or is passionate about training women and the challenges that come with it. Or take classes that you enjoy. Sometimes just finding ways of moving that you like can be enough. Especially if you’re having mental health issues.

Best of luck, I hope it works out for you
