While he has clearly lost size you really shouldn't judge someone physique when they are in a suit. For all we know Dillet could be 4% bodyfat under that and in the best cardiovascular shape of his life. Meanwhile Bob is probably 30% with clogged arteries and a failing kidney.
If you asked a Dr based on this pic which 60-year-old man looks healthier every single one is going to say Dillet.
