The "all or nothing" mindset is arguably one of the worst approaches to weight loss and health. It sets unrealistic expectations, often leading to a cycle of intense effort followed by inevitable failure when perfection isn’t achieved. Life is unpredictable—work commitments, personal issues, and health struggles will inevitably arise, making it impossible to always stick perfectly to a plan. Instead, adopt a "do something" mindset. This means making the best choices you can under the circumstances, even if they're not perfect. Small, consistent actions add up over time and are more sustainable than striving for perfection, which often leads to giving up entirely.
