Fat has had a lot of bad press and for many people, just a mention of word can evoke misery. You can try to lose it, try to hide it, try to avoid it, but your body still needs it! Did you know that fat helps to insulate our nerve cells, keeps us warm, balances our hormones, keeps skin and arteries supple, lubricates joints and is a component in every cell?

The key issue here is recognizing which type of fat your body needs, how much your body requires and which type is your enemy. Armed with right information, you can focus on getting more of good fats and less of bad fats into your daily diet.

There are two types of fat to be aware of. Saturated fats - let's call them "the enemy" and unsaturated fats - "the good guys"! It is easy to tell difference because saturated fats are hard at room temperature. Saturated fats are not essential to your health. They come from animals and are found in meat, eggs and cheese. They are harder to digest and full of cholesterol.

Unsaturated fats are liquid at room temperature and have been divided into two groups. Monounsaturated fats such as olive oil, and polyunsaturated fats such as sunflower oil. Polyunsaturated fats are split into Omega 3 fatty acids and Omega 6 fatty acids. Monounsaturated fat (Omega 9) although not essential, is not harmful in moderation - a good quality (extra virgin first cold pressed) olive oil is a healthier alternative to usual vegetable oil. Good sources of Omega 6: safflower oil, sunflower oil, evening primrose oil, walnut oil, pumpkin oil, sesame oil. Good sources of Omega 3 are mackerel, herring, salmon, pilchards, sardines, tuna and flax seed oil. Here are some important facts about fat in our diet.

1. Fat is 'energy reserve' of animals, plants and humans.

Dieters dread plateau. You're on a roll, losing weight steadily and happily for weeks. Your confidence is high and your goal is in sight. Then suddenly your scale freezes. No matter how hard you try, those extra pounds just refuse to budge. You've hit a wall and you know frustration of seeing no progress could easily lead you to gain back what you've lost. So how do you break through plateau?

It's perfectly normal for a dieter to reach a plateau. The trick is to use it as an opportunity to double up your efforts and get really clear on your strategy to carry you through to finish line. Below you'll find suggestions that can help you recommit to your program and re-ignite weight-loss process when you feel challenged.

1. Get clear on your ultimate weight-loss goal. Be sure that your weight-loss goal is realistic and that your expected rate of weight loss is reasonable. If you are on a heath enhancing, nutritionally rich weight loss program you can expect to loss one to two pounds a week. Each body has its own ideal weight and size. Don't compare yourself to anyone else, but listen to your body and notice what feels best for you. A simple way to approximate your ideal weight is by referring to a Body Mass Index chart.

2. Go high-protein, low carbs. Unless you are eating enough protein to maintain your lean muscle mass, you are likely to have lost weight already from both your fat stores and muscle. Women need to eat approximately 100grams of protein a day and men 150 grams in order to preserve their muscle tissue during a weight loss program. If you have lost some muscle during your weight loss program so far you will need to focus on protein so your body can build muscle, which requires more calories to sustain, which will in turn, kick start your weight loss again. Needless to say, any weight loss program you choose should be one that preserves your body's muscle and this does not happen!

3. Add resistance training to your program A wonderful way to boost your metabolism and break through to next level of weight loss is by incorporating aerobic exercise into your program, such as 30 minutes of walking three to four times a week. (If you are 35 years or older, or haven't exercised regularly, begin with 10 to 15 minutes two to three times a week.) In addition, weight training with free weights or machines several times a week can help increase muscle mass, which in turn allows you to burn more calories faster. Studies show that weight training can increase your metabolism overnight by five to 10 percent. Working out can increase your metabolism for up to 21 hours after an intense workout.
