CNN 播客“追逐生命”探讨减肥、健康和饮食。 CNN podcast "Chasing Life" explores weight loss, health, & diets. 传统观点认为，热量不足会导致体重减轻。 Conventional wisdom says calorie deficit leads to weight loss. 大部分研究支持“卡路里摄入/卡路里消耗”原则，但饮食类型（酮类、低脂、纯素）和进食频率也很重要。 Studies mostly support the "calories in/calories out" principle, but diet type (keto, low-fat, vegan) & eating frequency also matter. 营养师克里斯托弗·加德纳 (Christopher Gardner) 表示，饮食是主要因素，因为运动可以增加饥饿感和消耗卡路里。 Dietitian Christopher Gardner says diet is the main factor, as exercise can increase hunger & consumed calories.
