Millions of people resolve to get healthier by dieting and exercising more frequently at the start of each new year. According to data from the International Health, Racquet & Sportsclub Association, 12 percent of new gym memberships are opened in January. The second week of January is one of the busiest times of year in the fitness industry. But many people who decide to exercise more at the dawn of a new year quickly lose that resolve. New Year’s resolutions to diet may wane as well. In 2013, a UK food company found that of those who diet regularly, two out of five quit within the first seven days, one out of five last a month, and only 20 percent make it to the three-month mark. To make healthy resolutions last longer, people should recognize that results do not happen overnight and should not be discouraged by slow progress. In addition, diet and exercise is not a fast fix, but rather a lifestyle change. With consistent calorie control and exercise, people may see a gradual reduction in weight and other improvements to their overall health. Some may find it most effective to work with a nutritionist and a gym trainer.
