What’s more, due to their low calorie and high water contents, you can often eat a fairly large volume of these foods without consuming too many calories. Similar to negative-calorie foods, zero-calorie items — such as cold water — are often promoted as increasing metabolism. If these foods exist, you could theoretically lose weight by eating them, as you would use more calories eating and digesting them than you gain from their calorie content.

In the cost-push theory of inflation, rising wages in turn can help fuel inflation. In the case of collective bargaining, wage growth will be set as a function of inflationary expectations, which will be higher when inflation is high. In a sense, inflation begets further inflationary expectations, which beget further inflation. Keynesian economics proposes that changes in the money supply do not directly affect prices in the short run, and that visible inflation is the result of demand pressures in the economy expressing themselves in prices. Inflation measures are often modified over time, either for the relative weight of goods in the basket, or in the way in which goods and services from the present are compared with goods and services from the past.
The real purchasing power of fixed payments is eroded by inflation unless they are inflation-adjusted to keep their real values constant. In many countries, employment contracts, pension benefits, and government entitlements are tied to a cost-of-living index, typically to the consumer price index. A cost-of-living adjustment adjusts salaries based on changes in a cost-of-living index. It does not control inflation, but rather seeks to mitigate the consequences of inflation for those on fixed incomes.
