    Should you exercise on an empty stomach?

    You might've heard you'll burn more fat if you exercise in the morning before, or in lieu of breakfast. There is some research to back that claim up, but the science on fasted exercise isn’t clear cut. Norman and Tegan work through the evidence on exercising on an empty stomach, and what you can do to maximise your workouts. References: Effects of fasted vs fed-state exercise on performance and post-exercise metabolism: A systematic review and meta-analysisEffect of Overnight Fasted Exercise on Weight Loss and Body Composition: A Systematic Review and Meta-AnalysisInterval training in the fed or fasted state improves body composition and muscle oxidative capacity in overweight womenEffects of exercise before or after meal ingestion on fat balance and postprandial metabolism in overweight menEffects of time-restricted eating with exercise on body composition in adults: a systematic review and meta-analysisExercising in the Fasted State Reduced 24-Hour Energy Intake in Active Male Adults Appetite, energy intake and resting metabolic responses to 60 min treadmill running performed in a fasted versus a postprandial state Fasting Before Evening Exercise Reduces Net Energy Intake and Increases Fat Oxidation, but Impairs Performance in Healthy Males and FemalesFasted cardio is an attempt to burn stored fatIf you enjoyed this episode, check these out!

    Does hypnotherapy work?

    Sit back and relax. Close your eyes. Imagine you're sitting on a calm beach. Now, do you feel more open to suggestion? Hypnotherapy has been around for centuries, and you might've heard about it being used for everything from PTSD to addiction and even IBS. Norman and Tegan guide us through the evidence for using hypnosis in a therapeutic setting, and whether there are any downsides.

    NMN, NAD+ and other acronyms of anti-aging

    As we age, levels of a vital molecule called nicotinamide adenine dinucleotide (NAD+) decline. Could reversing this be the key to eternal youth? There’s huge interest in NAD-boosting supplements like nicotinamide mononucleotide (NMN). But is there good evidence that they can help us live longer, healthier? Norman and Tegan unpack how NAD+ became the focus of anti-aging proponents. This episode first aired on November 4, 2024.

    How bad is shift work for your health?

    Shift workers make a lot of sacrifices to keep the world running. What are they sacrificing in terms of their own health? There are harms associated with working at all hours against your body clock. Norman and Tegan work through what those are, and what you can do to protect against them.

    Eat the rainbow: what can food colour tell us?

    When you're done with your weekly grocery shop, how colourful is your trolley? We know eating lots of fruits and vegetables is good for you, but colour could matter. Norman and Tegan discuss what gives fruit and veggies their hue and whether it's important when it comes to healthy eating.

    Mouthwash: good or bad for you?

    How much time does your oral hygiene routine take? You brush, floss, interdent, maybe even use a tongue scraper. Is using a mouthwash going to give you any additional benefit? Or could you be doing some harm? Norman and Tegan answer questions about the effectiveness of mouthwash, what it does to your oral microbiome and why there might be a link to blood pressure.

    Why wear a continuous glucose monitor?

    Continuous glucose monitors, or CGMs, have transformed how people with diabetes manage their blood sugar. But in wellness circles, more and more people without diabetes are being encouraged to try these devices. Norman and Tegan get to the bottom of what these devices can actually tell you, and the potential harms.

    Are rest days from exercise necessary?

    Not many people would argue that rest isn’t important, but how would you define a rest day? For an elite athlete a rest day could be going for a long walk. For your average person it could mean sitting on the couch. Norman and Tegan ask – why is rest important, and do you need it to make progress in the gym?
