Mc Donalds is a restaurant where a lot of choices are available but some of it is junk food. It's quick though.
I'm not a huge fan of McDonalds. I prefer something like Chick-Fil-A
I do too actually.  Junk food is considered having high levels of calories with low levels of nutritional value.  
It's frustrating that it is more affordable to buy food that isn't really good for you.
I agree, we spend quite a bit on real food and I look at the cost of over processed junk and sigh.
Same. Our grocery bill went up significantly when trying to cut out filler foods and replace them with only healthy options.
And there are so many junk food options that are quick but I still prefer real food, even if it takes longer to fix.
Sometimes it's just easier to hit up a drive though. I agree, though. Making something from scratch always ends up being way more satisfying and healthier.
Fat tax
A fat tax is a tax or surcharge that is placed upon fattening food, beverages or on overweight individuals. It is considered an example of Pigovian taxation. A fat tax aims to discourage unhealthy diets and offset the economic costs of obesity.
A fat tax aims to decrease the consumption of foods that are linked to obesity. A related idea is to tax foods that are linked to increased risk of coronary heart disease. Numerous studies suggest that as the price of a food decreases, individuals get fatter.
foods are junk foods, most are. Fast foods are ready-to-eat foods served promptly after ordering. Some fast foods are high in calories and low in nutritional value, while other fast foods, such as salads, may be low in calories and high in nutritional value."
Junk food provides empty calories, supplying little or none of the protein, vitamins, or minerals required for a nutritious diet. Many foods, such as hamburgers, pizza, and tacos, can be considered either healthy or junk
