Stop eating yourself stupid we all know that poor nutrition can lead to bad health and even weight gain. Now add “lack of intelligence” to the growing list. A recent study has found that what you eat could very likely play a role in how smart you are.

According to the study, rats fed a high-fat diet for 10 days showed signs of weakness and even had trouble finding food that was waiting for them.小题1: Actually a high-fat diet could weaken our intelligence--but so can a low-calorie diet. The trick appears to lie in finding a nice balance.

Here are ways to achieve that happy balance and make you smarter through diet, exercise and improving your brain power.

Figure out how many calories you need to maintain your weight. __小题2:__ If you need to drop a few pounds, take away the number you get by 400 calories; consume that number of calories each day until you drop the weight.

__小题3:__Aim for healthy foods that include good amounts of protein, fiber, fruits and vegetables, healthy whole grains, healthy fats and plenty of water. Well! Remember: All work and no play makes Jack a dull boy. Read a book. Try a new recipe. Do some puzzles. __小题4:__

Exercise regularly with a positive attitude. Aim for at least three 30-minute training sessions a week(but more is better). I like simple exercise such as walking, but anything that raises the heart rate is good. _小题5:_  Combine them! Some people like to listen to classical music such as Bach or Mozart, but rock music lovers will be happy to learn that this kind of music can help make them smarter as well.
