No they have not been getting "healthier".While fast-food chains have ostensibly been trying to offer more healthful options, a new study finds that the health impact of their menus has not improved — to the contrary, in fact.
Explanation:
The entire point of fast food is that it is cheap and quick to make. Healthier food is more expensive, at least assuming that you want food that is at all filling (a light salad and some fruit can be ready quickly but it won't fill you up). It will also take more effort to make it appetizing.
A sedentary lifestyle means you don't move anywhere. Similar to coral or sponges.
