@Deborah Clegg : 我认为身体脂肪对健康至关重要,过少和过多都不利。女性需要足够的脂肪才能怀孕,而且脂肪实际上是一个内分泌器官,分泌有益的激素。健康的脂肪细胞像氨纶一样具有扩张能力,而不健康的脂肪细胞则被结缔组织包裹,无法扩张,导致卡路里进入肝脏或心脏等不该去的地方。男女的身体脂肪分布不同,女性倾向于将脂肪储存在臀部和大腿,且这种储存方式是健康的,而男性倾向于将脂肪储存在腹部区域,以便快速利用能量。但是男性腹部的脂肪不宜过多,过多的腹部脂肪是不健康的。男性比女性更容易减肥,因为女性的身体设计是为了储存额外的卡路里。臀部和大腿的脂肪是健康的脂肪。面对身体脂肪分布的变化,要保持宽容,注意饮食和锻炼。增加肌肉可以提高代谢率,建议进行负重活动并变换锻炼方式。应该更加注重饮食,避免食用过度加工的食物,食用加工食品即使摄入相同卡路里,也比食用非加工食品更不健康。应该回归更健康的饮食,选择新鲜水果和蔬菜,自己烹饪或确保使用新鲜食材。 @Sarah Berry : 我认为绝经后女性对富含碳水化合物的食物血糖反应更高,因此应注意饮食类型,减少精制碳水化合物的摄入。

Deep Dive

Chapters
This chapter explores the fundamental nature of body fat, its role as an energy reserve, and its endocrine function. It challenges the misconception that all fat is bad and highlights the importance of body fat for both men and women's health.
  • Body fat is stored in adipocytes (fat cells).
  • Insufficient body fat can be detrimental to health.
  • Body fat acts as an endocrine organ, secreting hormones.
  • Healthy fat cells can expand to store calories, unlike unhealthy fat cells which are encased in connective tissue.

Shownotes Transcript

Today we’re discussing fat.

It’s a word that carries a lot of weight. It’s a source of social judgment, a driver of insecurities and a tool exploited by companies in targeted marketing campaigns. It’s no surprise that a recent study found over 40% of people in the US have experienced some form of ‘fat-shaming’.

But do we really understand fat? What it does, how it forms and why its distribution changes as we age.

Prof. Sarah Berry and Prof. Deborah Clegg are here to help us answer some of these questions and change our perception of fat. Deborah Clegg is a professor and Vice President for Research at the Texas Tech University Health Sciences Center, El Paso. Sarah is Chief Scientist at ZOE and Professor at King’s College London.
