School lunches are too small

Although there is a problem of obesity in America, punishing all students by making portion sizes smaller is unfair. While making the portions smaller it doesn't even stop the students from getting more food, the government is just making students and families pay more and more money in order for their kid to be properly fed. As well as the portioning being smaller, if a student chooses to get the "healthier" salad or sandwich at lunch it is $1 extra as well as the more fruit or vegetables a student takes costs extra. Instead of making the portions small the government should have kids exercise more, helping them to burn the calories they are consuming. The government should regulate exercise instead of portion size. Therefore portion regulating causes many negatives, instead of positives.
