I want to lose weight?!

I am a nursing student and model and can give you advice on eating habits but cannot replace that of a doctor or dietician. Fist off, there is NO sure fire diet to lose weight. Weight gain is not solely based upon the food eaten and the amount of exercise. Factors such as genetics, endocrine deficiencies, mental disorders, individual metabolism, heredity, and stress all have large effects on what we eat and how it effects us. Some people can eat perfectly healthy and in small portions while exercising and still be upwards of 200 lbs. Also, some exercise burns more calories than others. For example, running burns a lot of calories and fat while bench pressing works muscle without burning nearly as much of the fat. That being said, here is some advice on eating habits:

1. Eat all day long. This may not be what you expect to hear, but eating several small meals tells your body that it has plenty of food and keeps your metabolism up rather than taking in your food in surges. Also, you will be generally less hungry.
2. Drink, drink, drink. Drink tons of water all day long, constantly. Adding lemon helps too. Lemon water all day long. Flushes your body, prevents water retention, and helps you lose weight.
3. Avoid carbs, sugars, dairy, and fried food. Cereals, bagels, pasta - they all turn to sugar. Eat mainly raw veggies and fruit. Cooking veggies takes out some of the natural vitamins in them. Cooked vegetables are in no way bad, but raw ones are healthier and don't have the butter/ oil / salt cooked into them. In addition to veggies and fruits (fruits are high in sugar, so be careful), eat small portions of protein that is low in fat. Chicken and fish are the best (not tilapia though). Eat smaller portions of these. Eggs are good sources of protein if they are not overcooked, and are cooked with steam, no grease or butter. Also, they should not be served with bacon, sausage, cheese or croissants, as delicious as it is.
4. Avoid eating when bored, stressed, sad, or doing work. Avoid mindless eating. When you get a snack, get a small portion and take it with you. Do not sit there with a bottomless bag of pretzels or before you know it you will have eaten the whole thing.
5. If you do mindless eat, try celery. You actually burn calories eating it!! Stock up! My fridge always has some.

Here are some examples of a healthy day's worth of food:
Breakfast: Half a grapefruit or one cup oatmeal (not the sugar loaded kind) or a steamed egg with a slice of toast or a reasonable size bowl of a healthy cereal (ie special K, mini wheats, honey bunches of oats)
Snack: Apple, orange, carrots, celery, other fruits / veggies
Lunch: plain grilled chicken (1/4th - 1/2 a breast), a serving of carrots and other raw veggies. or fruit.
Snack: about 10 pretzels, or veggies / fruit
Dinner: Grilled chicken (1/2 breast should be enough). Some cooked broccoli or spinach or whatever veggie you like (corn and potatoes are starches and should only be eaten in small quantities). 1/4 a roasted garlic potato or pasta side dish or other grain.
Desert: Strawberries, 1/4th-1/2 C low fat double churned ice cream (no worse for you than a yogurt out of the fridge!)

Proportions are KEY. Eat smaller amounts, keep your diet balanced. I know it gets boring but the grilled chicken and raw veggies work. Don't forget to keep drinking. Hot water and hot tea help keep you full if you feel like you are still hungry.

I am not going to lie to you and say its easy. Weight loss is hard and your not giving yourself much time.
Everyone is going to tell you eat healthy, but really cut your calories down you could eat 1200 calories of chips and loose weight!
Drink lots of diet drinks and water to feel full and chew lots of gum so you don't snack.

Try to get some exercise also!
