It worked for me at first…
When I first started using Lumen I lost 20 pounds following its nutrition plan and my metabolism improved tremendously. Then something changed. I remember there was an app update and it changed my nutrition plan to something unmanageable. I think AI was used to make adjustments and it stopped working for me. I stopped enjoying using it. My metabolism score also dropped. Whatever they had in the beginning was perfect. Anyway, I gave it 3 stars because it initially did help me. I sort of stopped trusting the nutritional guidance. I started using Noom and it’s much more realistic and dynamic (real time macro changes).
