The term ‘junk’ means useless or of little value. Junk food is highly processed food with little to no nutritional value and is often high in calories and fat. Consuming junk food does not pose any immediate health risk, but the habit of consuming junk foods regularly which are deficient in protein, vitamins and minerals can be severely detrimental to one’s health. People who consume junk food every day are very likely to be fat and overweight because with junk food all they are consuming is a lot of calories. People who are trying to lose weight must avoid junk food at any cost.
