10 Weight Loss Diet Rules

1. Cut out all carbonated drinks. It doesn't matter if they're diet or not, your body does not need them. 
2. Drink more water. You need to be getting about 6-8 pints of water each day, depending on your activity levels. This may seem a lot at first, but if you break it down into smaller batches, its quite easy to hit your total.
3. Eat 3 meals a day. This means breakfast, lunch and dinner. Having three meals a  day gives your body a consistent stream of nutrients and stops you getting tired. Missing a meal reduces how well your body is functioning and can actually slow down the weight loss process
4. No snacking. Snacking is one of the worst things you can do when trying to lose weight. The three meals you have each day should be substantial enough to get you through the day. Most snacking is through boredom, so you just have to be strict with yourself. 
5. Cut out alcohol. Alcohol is bad for weight loss, end of story. Going teetotal during your diet means your body is functioning better and burning energy more effectively, it doesn't have to deal with processing the alcohol in your system.
6. Don't starve yourself. Work out your  base metabolic rate (BMR) you can find tools on-line to help you work it out. Once you know your BMR, take 100-200 calories off that number to get the amount for your diet. Cutting your calorie intake excessively actually causes your body to start holing onto fat more, as it doesn't expect your reserves to replaced any time soon and goes into a self-preservation mode.
7. Increase your protein intake. Proteins are the building blocks of your body. Keeping your intake of them high is important to stop muscle wastage. Losing fat is all very well, but if your let your muscle waste while you do it, you'll end up as skeleton wearing skin. Protein also counts towards your daily calorie allowance and fills you up quite quickly, reducing the change of feeling hungry after a meal.
8. Eat Fats. Fats are essential to the working of your body. If you cut out fats completely then your body will slowly start to struggle. This doesn't mean go out of your way to eat fatty foods. Just don't make a point of cutting them out of all your meals. If a piece of meat has fat in it, that's fine, eat it anyway. This source of fat is good for you.
9. Vegetables These are the filler of many of your meals. Increasing your vegetable portion size will make a big difference to your meal sizes. Veg doesn't carry many carbohydrates, while being rich in vitamins and minerals so fill up on these instead of pasta, rice or bread.
10. Exercise I know this isn't part of a diet, but for maximum progress you need to make sure you exercise on a regular basis. This can be something as basic as going for a walk or taking the stairs instead of the lift. Being active accelerates weight loss immensely, the extra effort will be worth it!
