In sum, there is little support for the notion that diets ["severely restricting one’s calorie intake"] lead to lasting weight loss or health benefits.
Mental toughness is a psychological edge that helps one perform at a high level consistently. Mentally tough athletes exhibit four characteristics: a strong self-belief (confidence) in their ability to perform well, an internal motivation to be successful, the ability to focus one’s thoughts and feelings without distraction, and composure under pressure. Self-efficacy is a belief that one can successfully perform a specific task. In sport, self-efficacy has been conceptualized as sport-confidence. However, efficacy beliefs are specific to a certain task (e.g., I believe I can successfully make both free throws), whereas confidence is a more general feeling (e.g., I believe I will have a good game today). Arousal refers to one's physiological and cognitive activation. While many researchers have explored the relationship between arousal and performance, one unifying theory has not yet been developed. However, research does suggest perception of arousal (i.e., as either good or bad) is related to performance. Motivation can be defined broadly as the will to perform a given task. People who play or perform for internal reasons, such as enjoyment and satisfaction, are said to be intrinsically motivated, while people who play for external reasons, such as money or attention from others, are extrinsically motivated.
Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
