Which of followings is not mentioned in the experts’ advice?

参考解析：

细节理解题。根据文章第三段最后一句“Instead, opt for complex carbohydrates such as porridge or wholegrain bread or fish with potatoes instead of high-fat, high-calorie beef and steak which will give you the energy you need to face a difficult day”可知，相反，选择复合碳水化合物，如麦片粥、全麦面包或土豆鱼，而不是高脂肪、高热量的牛肉和牛排，这会给你面对艰难的一天所需的能量，排除A选项；根据文章第五段第一句“If you can’t afford to visit a gym, or have responsibilities that keep you at home, there are plenty of free home-based workouts that can be squeezed into a few minutes.”可知，如果你负担不起去健身房的费用，或者有责任让你呆在家里，有很多免费的在家锻炼，可以挤出几分钟时间，排除B选项；根据文章最后一段第一句“Don’t be afraid to seek professional help.”可知，不要害怕寻求专业的帮助。排除C选项。故选D。
