Because by losing 1 electron it attains noble gas configuration which is a stable configuration for any element. And M+2 ions will have unstable configuration.

Explanation:
because alkali metal can lose only one electron ,alkali metal ion M+ is formed which has stable noble gas configuration.and it is very diffcult to remove another electron to form M+2 ion as second ionization enthalpy is very high.
