Just exercise more then your body will be able to tahan late
night.
If not, incorporate some sort of exercise like walking or
climbing stairs during office hours and after working hours.
Also, observe your diets and control what you eat.
The more natural is your food, the less energy it need to
process it.
One more things is to keep your waist down.
I also have the same issue and in the process of improving
fitness.
