1. Don't rush into the toughest diet you can find.
This is a common mistake. Many people decide in a moment of desperation to follow a super-strict diet and fail. Don't rush into a diet that may be too strict for you. If you don't have any dieting experience and are not 100 percent sure you can stick with the diet, then choose something else.
2. Don't lose touch with reality.
You can't realistically expect things to happen over night. When choosing your goal, start small, but be prepared to go far. If you hear someone saying that he lost a large number of pounds in a short time, don't make it your goal to match his performance. Diet results are different from one person to another.
3. Don't go to the gym too often
Another common mistake is to use the enthusiasm of the first days to hit the gym every day. This won't help you at all. Your body needs time to heal and expand the muscle mass after each training session and going to the gym every day interferes with this natural process. Besides, a week of non-stop training could never offset ten or twenty years of couch potato lifestyle.
4. Don't get hard on calories.
We all know that cutting down on calories is one of the building blocks of all diets, but you have to be careful about it. Cut down on too many calories and your body will start storing anything it possibly can. This is not a good way to lose weight.
5. Don't skip meals.
Some people think that skipping one or two meals could help them lose weight faster. They don't understand that dieting is all about eating the right food and not starving yourself.
6. Don't check the bathroom scales everyday.
Everybody is eager to see the confirmation of his or her efforts in the shape of lost pounds, but you should not let this drive you to checking your weight everyday. The daily fluctuations of your weight will soon have you depressed and ready to quit dieting. And this is something you want to avoid.
7. Don't let emotions drive you.
Aside from the eagerness that drives people to check their weight every day, there are other emotions that influence dieting. If you know you're used to reaching out for ice-cream or snacks when you are bored, frustrated or angry, then you should deal with these issues and not allow them to come between you and your purpose.
8. Don't refuse to seek help.
Not everyone was born with iron will and nerves of steel. If you need advice or help, don't hesitate to ask it from your friends or from professionals. Don't try to solve all problems by yourself.
9. Don't deny yourself your favourite foods.
Treats are a great way of raising your willpower and determination. Diets are just food control methods, not prisons. So what if you eat something forbidden once in a while, especially if that food is a favourite of yours? If such treats are not frequent, then they will make no difference in the long run.
10. Don't rely on your willpower alone
Use your head as well. If you wish to know how much you eat, then write everything down and analyze the list for things that should not be there. Sometimes hunger creeps up on you and make you eat something you shouldn't. Be honest with yourself and keep a clear head.
