Fats are lipids; honey is carbohydrate.
Fat is a storage medium and contains twice the energy per unit mass than carbohydrate.
Carbohydrate is easily assimilated when energy is required so it is mainly stored, short term, it in the liver, from where it is changed to simple sugars and rapidly distributed to where required via the circulatory system.
Excess carbohydrate (or fat) is stored longer term as fat. So eating too much fat (twice the energy value of the carbohydrate) is really bad for getting fat and carbohydrates, when converted to half the weight as fats are bad, too.
Obviously carbohydrate is converted to fat (and fat back to sugars), but that is a slower process as it is naturally the method for longer term storage (as a higher energy density food).
One might use the analogy that an armfull of wood might only need half that amount of a good coal to get the same amount of heat from the fire.
People get fat by eating too much or the wrong diet. Some may have conditions that make it difficult to avoid getting obese, but most of us simply eat too much compared to our physical activity. Lifestyle is what it is down to. People don't have to get fat. More than once, the point has been put forward that the only fat people in the concentration camps of WWII were the guards.

Honey is no different than a lot of foods (better than a lot, too).
