First, read the English article below.

One of the biggest mistakes many dieters make is skipping meals in order to cut calories. This is a bad idea for several reasons:  Firstly, skipping meals will leave you feeling constantly hungry and deprived, making you much more likely to binge later in the day, or just give up on your diet completely. Secondly, skipping meals will leave you feeling tired with no energy, which is bad for your work productivity, your stress-levels and your motivation to exercise. It's important to eat frequently throughout the day to keep your blood sugar levels even and your energy up. It's especially important to eat breakfast (the most commonly skipped meal) as it kickstarts your metabolism and sets you up for the day. To stick within your 1,200 calorie limit, eat three 400-calorie meals every day. In terms of quantity, you should have a large breakfast, a medium-size lunch and a small dinner - this simple change alone can help you to lose weight. As much as possible you should try to stick to lean proteins (chicken, turkey, fish, lean red meat) and greens (broccoli, spinach, kale, asparagus and lettuce) when attempting to lose weight.  Avoid simple carbohydrates (which are found in items like bread, pasta and white rice) as these tend to trigger your appetite, causing you to eat more. According to weight loss experts, if you stick to eating green vegetables and lean protein at most meals, you can lose up to three pounds a week. Skip sugary drinks, such as juice or soda, and drink plain water instead if you want to lose weight quickly. You may not realize it, but you may be consuming up to 250 extra calories in sugary drinks daily.  If plain water bores you, try seltzer or unsweetened ice tea. Herbal teas are the best option if you feel like sipping a hot drink, but black tea and coffee are also acceptable. Avoid lattes, cappuccinos and blended coffee drinks, as these also contain a ton of calories. You should also cut back on the amount of alcohol you consume - a single 6 oz. glass of red wine contains 150 calories....
