Today you can cut down on sugar. Tomorrow... do the same and eat something home made with fresh ingredients and no preservatives and additives. The day after tomorrow...do all the above and dance to music. These things are a start. One day is all you need to undo a lifetime of hurt. One day is all you need to undo a lifetime of damage. Because before you know it, that ONE day had turned into a week, then a month and then a year. ONE year from now you can be a completely different person in a completely different body.
By the way life is flashing past us, one year is going to feel like a matter of weeks.
So, love the stars. Cook healthy meals for you and your family for dinner. Make time to enjoy your family after a hard day's work and then dance yourself happy and thin before you go to bed. About 30 minutes dancing out of a WHOLE day is not impossible.
