Hi, all the above lifestyle will reduce or slower the process of atherosclerosis but may not reverse.
Plaques have multiple causes and bad life style is one of the major contributors.
To reverse you might need medication but the outcome is also not predictable.
I would suggest if you do not have a family history of heart disease
If your
lipid profile is normal
And still you have plaques then please follow a routine heart healthy lifestyle and food.
Consult a cardiologist once a year to see the progression of disease
Avoid stressful life and prefer meditation
Avoid any form of addiction
