What does a normal person lose by following the path?
What you gradually lose by practicing the path is:


Taṇhā
Nīvarana see: Nīvaraṇa by Piya Tan
Akusala,mūla
Anusaya see: Anusaya by Piya Tan
Saṁyojana
Kilesa
Asava


None of which are pleasant to have or worthwhile to have or keep around. What you gain is unshakable peace and happiness (free from Dukkha or Nirvana). In addition you end Jarāmaraṇa and the cycle of Dependent Origination.

As per what you said in your text you are able to enjoy more which perhaps is due to reduction of the above undesirables. Once the are completely gone only happiness remain. This happiness is stable and not dependent on anything else and does not end. Therefore, you will be able to enjoy life like never before through not they type of enjoyment you have experienced before (ämisa sukha). This is a more higher type of enjoyment (niramisa sukha).
