Scott Keatley, R.D., a co-owner of Keatley Medical Nutrition Therapy, provides expert advice in response to Gwyneth Paltrow's dietary regimen, which has been a subject of public scrutiny. He emphasizes the importance of matching caloric intake with energy expenditure, especially when engaging in regular exercise. Keatley warns against overly restrictive diets, noting that they can lead to short-term issues such as lack of energy, dizziness, and low blood sugar, as well as long-term health problems including nutritional deficiencies and decreased muscle mass. To ensure sufficient caloric intake, he recommends calculating one's basal metabolic rate and adjusting diet accordingly. Keatley advocates for a balanced diet rich in carbohydrates, proteins, and fats to support bodily functions and promote muscle repair and growth. He underscores the importance of a healthy relationship with food and exercise, suggesting that they should enhance life rather than cause anxiety. His approach advocates for mindful eating, regular physical activity, and stress management to achieve better health outcomes.
