Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they're in poorly lit places — and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

Mind the colours. Research suggests warm colours fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colours like yellow make food appear more appetizing, while cold colours make us feel less hungry. So when it's time to repaint, go blue.

Don't forget the clock — or the radio. People who eat slowly tend to consume about 70 fewer calories per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And well pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

Food safety is a problem in all places around the world and people in different areas of the world prepare food in different ways. The WHO released five simple rules for preparing food in a safe way. They call these rules the "Five Keys to Safer Food".

Key 1: Keep clean.

People should wash their hands often—before touching food and while they are preparing food. People should wash all surfaces and equipment used for preparing food.

Key 2: Separate raw and cooked.

Raw food should not touch prepared food.

Key 3:

People should cook eggs and meat especially carefully. These food may carry more micro-organisms than other food. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people reheat cooked food completely.

Key 4: Keep food at safe temperatures.

When people finish eating, they should keep the left food in a refrigerator below 5℃ and shouldn't store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. But temperatures above 60℃ or below 5℃, control the growth of micro-organisms.

Key 5: Use safe water and raw materials.

Damaged or old food may develop harmful chemicals as it gets older.
