Jonathan Wolf:本期节目探讨卡路里计数是否有效,并邀请营养学家Sarah Berry进行深入分析。节目一开始便提醒听众,如果对卡路里计数和食物限制感到不适,可以跳过本期。节目中,Jonathan Wolf和Sarah Berry讨论了卡路里计数的原理、局限性和长期影响。他们指出,虽然表面上卡路里计数似乎是减肥的有效方法,但实际上,卡路里测量的准确性存在问题,而且人体对不同食物中卡路里的吸收和利用效率也不同。此外,长期卡路里计数可能会导致节食反弹,因为减少卡路里摄入会引发强烈的饥饿感,进而导致摄入更多卡路里。他们建议,与其关注卡路里数量,不如关注食物质量,选择健康、营养的食物,例如植物性食物和富含纤维的食物,以促进长期健康和体重管理。 Sarah Berry:作为营养学家,Sarah Berry详细解释了卡路里的定义和测量方法,并指出卡路里测量的误差可能很大,例如坚果的实际可吸收卡路里比包装上标注的少30%-40%。她强调,长期卡路里计数可能导致饮食质量下降,因为人们往往会选择低脂低糖的加工食品来控制卡路里摄入,而这些食品通常不健康。她建议人们关注食物种类,选择健康、多样化的饮食,例如植物性食物和富含纤维的食物,这更有利于长期健康和体重管理。她还区分了“快卡路里”和“慢卡路里”食物,前者是高度加工食品,吸收快,导致血糖波动大,更容易饿;后者是低加工食品,吸收慢,血糖波动小,不容易饿。

Shownotes Transcript

Food package labels can be complex. With so much information, many of us set a beeline for the calorie number, but there’s more going on in food than just the amount of energy. How much value is there in counting calories, and should you continue? The latest science could make you reconsider. 

In today’s daily episode of ZOE Science & Nutrition, Jonathan is joined by Dr Sarah Berry to answer the question: Does calorie counting work?

This episode is part of a limited series to celebrate the launch of The Big IF study: The world’s biggest clinical study to discover how intermittent fasting affects our mood, energy and hunger.  Want to know if intermittent fasting can work for you?
