Each January, millions of Americans make resolutions to become healthier and lose weight, but research suggests the majority of resolutions fail. Life Time, a healthy lifestyle brand, surveyed thousands of its members nationwide to determine trends, habits and what was motivating them to get healthy in the New Year. 

Notably, nearly 50% of respondents would give up pizza forever in order to stay at their goal weight/physique. Women especially favored giving up pizza, while men favored giving up alcohol. 

When it comes to motivation, 11% of respondents admitted their main motivating factor was "doing it for the gram. Similarly, 30% were motivated by their own self-image. And, 44% noted health concerns as the number one reason motivating them to lose weight in the New Year.

Additional highlights of the survey results include:

More than 66% of respondents say they feel healthier now than they did 5 years ago.

47% of respondents feel the hardest commitment to stick with is a wellness/fitness routine, followed by 33% specifying a subscription service (meal service delivery).

Life Time conducted the survey as part of its annual commitment to One Positive Action through Commitment Day, which launched on January 1, 2013, as a nationwide movement to inspire and encourage positive change. Since then, hundreds of thousands have participated in making a commitment to better their health, communities and selves.
