Simply "not using the brakes" and driving at the same speeds and accelerations will use the same amount of fuel.
Not so - utilising engine braking saves energy over using friction braking. Any modern (within the last 15 years) electronic fuel injection system will reduce fuel flow to zero, if the engine is being driven by the drive train. Slowing down in gear uses zero fuel, slowing down in neutral on the brakes uses brake pad material AND fuel (to keep the engine idling).
