Dear John,
Sorry to hear you are feeling sad about your overweight problem.I am writing to you because I have learned some potentially helpful ways from a famous health blog.
First,less snack,more fruits.You know when you have a lot of snack that contains much calories and these energy is not consumed by your body,the only result you will get is to turn these additional food into fat.Why don't you try some fruits when you are feeling to eat something?Fruits are rich in fiber and they will also help you to have a regular bowel movement,which is an ideal nutrition resource for you.
Second,less beverages (especially carbonated beverages),more water.It is obvious that those so-called ‘healthy drinks’ are nothing but sugar water with carbon dioxide in it.As you know,sugar is material contains much more calories than other food and there is almost no difference between drinking a lot of carbonated beverages and stuffing yourself with candies,cakes or anything sweet.So,please use water instead of those beverages when you are thirsty,not only for your weight problem,but also for your teeth and bones as carbon dioxide are bad for your bones’ density.
Third,participate in sports.By far we have discussed about ‘how to decrease calories that is brought into your body’,now we should move on to the topic that ‘how to burn these calories out’.Yes,you have guessed it.The answer is sports.When you are doing sports regularly,you will find the change in yourself sooner or later,and it will be a further activation for you to go to sports,which can construct a positive circulation and the result can be nothing but a more and more healthy,and of course,fit body.
yours,
Li Hua
