Struggling to diet

I have been trying to lose weight and I am struggling to find diet food. Preparing it is making the process harder. I am lazy I know. Any suggestions of places or people who deliver diet food to home?

And any real life weightloss experience with the places like kolors or minus clinic?

I'm looking to reduce around 20kgs. Ready to take medicines as well. I know it's unhealthy but this struggle is so hard. Please suggest.
