Nutrition Science Is Changing - Here’s What You Need to Know | Dr Sarah Berry

💬 “How you eat is so important, the time of day, how fast you eat, the ordering of the meal, how much sleep you’ve had” ~Dr Sarah Berry

⚡️ Dr Sarah Berry is a nutrition scientist at King’s College London, and Chief Scientist at ZOE. Her main areas of expertise revolve around the hot topic of precision or personalised nutrition.

⚡ In this episode Sarah and I explain why people can have such wildly different responses to food - from how many calories you absorb to your blood glucose response and more.

🎧 Stay tuned to find out:

➡ Why the calorie label on your food isn’t telling you the whole story

➡︎ How eating too fast could be the cause of your weight problems

➡︎ Why general dietary guidelines aren’t working (or being followed)

➡︎ How stress, sleep and many other factors can change your response to food

➡︎ Why the timing of your meal is important and how to fast the easy way
