To be fair, I eat sugary foods regularly and I too find Mars bar disgustingly sweet. Same with Snickers bar. They're just too sweet, regardless of who is eating them.
Shows just how desensitised to sugar I was as I could easily eat two or three(!) full size Mars bars before I cut out sugar.
If I was running late in the morning I would have a Mars bar and a 330ml bottle of Coke or Pepsi for breakfast!
Looking back I am embarrassed at how shit my diet was. I would eat sweets and sofa for breakfast and a grab a takeaway on the way home (often Chinese as it was near my house). The only "normal" meal I would eat would be lunch at my work restaurant. However it was subsidised which would also lead me to over eating as it was so cheap and I was always hungry from having junk for breakfast.
By my late twenties/early thirties I was around 112KG (~247lbs) on a 184cm (6 foot) body. Shocking.
