first get yourself checked out with teh dr… to rule out anything that maybe wrong with you.. even tell them tat you are thinking about starting up a work out routine and if its ok for you health wise… and if you should be taking any kinda supplements to help you remain energetic .. i know anaemic ppl have a hard time keep the energy up .. i can sometimes be that myself so i know…
as for food… my husband is a major eater… i make him what he wants.. though try to keep it healthy cuz i care bout him too .. a little..
but i just have a lot of self control when it comes to food… im not high on carbs .. and have a salad for lunch… but for dinner i have my rice or roti etc.. cuz you need food to keep you healthy… this is not meant to be a yo yo diet.. the only thing you are meant to limit is junk food.. dont deny yourself it either.. but be smart…
the rest.. just work out… i havent made any drastic chnages to my diet cept limiting junk food.. and its worked.
