Dear Emily,
HI
I know every girl wants sexy body besides you.But please do know that every coin has two sides.
If you want to lose weight,you should prefer a correct way not just for the result.
After a long winter,you may gain weight,spring is a good season to lose weight,Firstly,you can make a plan for yourself.
Do you like any pop star,if so ,you can put up one pic on your bedroom,so that you have your aim.
Then pay much attention to your diet,not just eat vegetables all the days,you should have your dinner according to the clock,one day three meals.
Meat can make you strong,vegetables and fruits can give you vitamin.
Secondly,you should spare time to exercise everyday no matter the weather like.
It's reported there's a new way to exercise,it's 20 minutes.The first eight minutes,you try your best to exerise,the left 12 minutes you slow down,and this is proved by many foreigners and scientists.
As the old saying goes,there's a will,there's a way.
If you continue to exerise and care your diet,I believe that you will look good in summer.
Yours,
Dr.Eaatright
