Questions & Answers

Q: How does intermittent fasting work, and what are the potential health benefits?

Intermittent fasting involves restricting one's feeding behavior to specific time windows within a 24-hour cycle. Studies have shown that it can improve liver enzymes and insulin sensitivity, leading to various health benefits. However, it is crucial to maintain adequate fluid and electrolyte intake during fasting periods.

Q: Does eating early in the day result in more muscle growth and maintenance?

Research suggests that ingesting quality protein early in the day, particularly amino acids like leucine, can enhance muscle hypertrophy and growth. The body's circadian clock mechanism, specifically the BMAL gene, influences muscle protein synthesis. However, this does not mean that protein intake later in the day should be avoided altogether.

Q: What are the main characteristics of anorexia nervosa?

Anorexia nervosa is a severe eating disorder characterized by a refusal to maintain a healthy body weight, an intense fear of gaining weight, and distorted body image. It often leads to extreme weight loss, loss of muscle mass, bone density, and disrupted bodily functions. Anorexia is highly dangerous and potentially life-threatening if left untreated.

Q: How does bulimia differ from anorexia?

Bulimia involves episodes of binge eating where individuals consume an excessive amount of calories in a short period. Unlike anorexia, bulimics engage in compensatory behaviors such as vomiting or excessive exercise to prevent weight gain. Bulimia is associated with impulsivity and disrupted reward systems, leading to a loss of control over eating and feelings of guilt or shame.
