Dr. Hazel Wallace Nutrition Podcast Quotes & Highlights

2:20 – Hazel’s Inspiration. Hazel talks about how losing her father at the age of 14 inspired her to go into medicine.

6:30 – Small Improvements. “I think a lot of people think it all needs to happen at once or that results are going to happen really quickly. And that’s not what happens. It’s what we do every day and the small things that we do every day that amounts to better health in the future.”

8:42 – Sleep and Metabolism. Hazel explains why sleep is a key component to better metabolic health and how your hormones react to good sleep and bad sleep.

10:52 – Meal Timing and Sleep. “It’s less about what you’re eating, but more about when you’re eating when it comes to sleep,” Hazel says. “When we eat, we are sending a signal to our body that it’s daytime. And so if you’re eating at say 9:00 PM at night, and you’re having a big meal, you are essentially causing a shift in your circadian rhythm, which is going to make it more difficult for you to fall asleep.”

How Eating Before Bed Affects Your Sleep and Recovery

13:53 – Finding the Right Diet for You. “Nutrition is very individual when it comes to performance and recovery. There’s no single diet that stands out in terms of what we know from the research.”

17:00 – Gender Differences. Hazel explains how we use carbohydrates and fats during exercise, and notes that women can use fat at higher intensities than men. “It really just illustrates how important our hormones are in determining how we function,” Hazel says.

20:10 – Fasted Training for Women. “When it comes to fasted training, I think it’s super unique because I know a lot of people do well on training fasted, and sometimes I prefer it. The reason that I’m slightly cautious of advising it for women is that oftentimes it can lead to low energy availability, [which can] lead to menstrual cycle disturbances.”

27:37 – Finding the Best Version of Yourself. “We don’t have to accept mediocrity for ourselves. We don’t have to accept a sub-optimal state,” Kristen says. “There’s so much good information out there that we can grasp onto that we can build behaviors around that enable us to really be the best version of ourselves.”

28:50 – Behavior Change and Habit Formation. “You can’t just tell people to eat less and move more. That doesn’t work. It’s all down to behavior change and motivation,” Hazel says. “In order to build a new habit, it’s hard. It’s not easy. We all have these ingrained routines. You have to disrupt that to a degree and you have to be motivated to do it. What you do repeatedly shapes the person who you want to be.”

31:16 – Eliminating Unnecessary Steps. “If there are too many steps to what you’re trying to achieve, you’re more likely to not do it at all. You want to simplify the process.”

35:45 – Women’s Performance Collective. Hazel is a member of the newly formed WHOOP Women’s Performance Collective, and aims to better understand the difference between men and women through her own research. “Men and women are completely different. We’re not small men and we perform differently. We sleep differently. We use nutrients differently. Even down to the diseases that we suffer from, we experience them very differently.”
