Why childhood sweet comfort link subconscious weight association?

During profound thought, I am brought back to a dim recollection of how I was offered a sweet to avoid crying when I was a small child. My weight issues as an adult are a reverberation of that initial emotional scar. This is one thing intellectually but can meditation actually re-write that subconscious, deep association? Or have I been playing all my life with a program installed in my early years? Name: Karan Sethi DOB: 27th May 1987 Time: 8:50 PM Location: Nagpur
