I've been on a diet for 3 months and it's not working, is there a better way?

Only Diet will never help. You need to have some workouts as well. Start with a daily walk after lunch and dinner. Even the consumption of more healthy food too much leads to weight gain so avoid that too.

I am also struggling for fat loss ..pls help

Diets aren’t always one-size-fits-all, so it might be worth evaluating your approach. Focus on balance rather than strict restrictions, incorporating whole foods, lean proteins, and plenty of veggies. Regular exercise helps too, walking, yoga, or strength training can make a difference. I also found that tracking meals to spot hidden calories or portion issues really helped. If you’re stuck, consulting a professional could provide valuable insights, net health customer service might even help point you toward resources.
