Dr. Stacy Sims is dropping reality bombs again.

Sleep is like breathing. You can't decide to not breathe today and that you'll catch up tomorrow. The research is showing us that the cost of not sleeping well is much higher than originally thought.

Sleep quality has a huge impact on your performance, your immune system and your mental health.

Make a sleep a priority and your body and brain will reward you.

While we sleep, our bodies do a few incredibly important jobs. First, our bodies solidify memories and cognition. 🧠 It's also time to repair tissue and recover from your physical work during the day. 💪

In addition to aiding memory and tissue repair, sleep also is important for maintaining appetite and body composition and reducing cortisol.
Most of us can identify if our sleep is "good" or "bad" just by how we feel, but do you know how to read sleep data and adjust to get longer and/or better quality sleep? Here are a few things to know:

😴 One thing that we often forget about when talking about sleep is sleep consistency. This means going to bed the same time of day and waking up the same time of day. We want this in order to keep a consistent circadian rhythm & avoid phase shifting.

😴 We spend about 50% of our night in light sleep -- the time preceding REM sleep and slow wave sleep. We technically say light sleep is a transitional sleep between the really reparative sleeps.

😴 Around 25-30% of your total sleep should be in slow wave sleep. This is when your body is in it's full reparation mode. This phase is the most important for athletes...but also is the phase that's easily affected by anything that accelerates your sympathetic nervous system (ex: jet lag, eating before bed, consuming alcohol, consuming caffeine, etc.). Not great.

😴 REM is when we dream and when the body focuses on memory consolidation. For healthy sleep, we're aiming for about 20% of the night spent in REM.
Okay great, now you know a bit about what sleep is, but how does that help you get better sleep? This is why I created a Sleep Biohacking Activity Guide that walks you through how to conduct your own sleep improvement experiment using this sleep knowledge & researched sleep strategies.

This guide includes 2 exclusive podcasts discussing the science of sleep, my own sleep experiment results, and a discussion of results from people who have also participated in this experiment. This holiday season, I'm giving this guide away for FREE as a gift to all of you! 🎁

Got a visit from the legendary Colby Pearce. Super generous guy with a great view of why we ride bikes.

Some Very Interesting research coming out the Journal of Cell Metabolism on BMI and mBMI [metabolic Body Mass Index]
Looks in to what has become known as TOFI [Thin on the outside, Fat on the Inside] sometimes referred to as 'Skinny Fat'

We've relied on BMI for over 100 years, but researchers have developed a new measure - using your blood.

Sometimes what you think might be a good idea isn't doing what you though it was.

From a health standpoint, intermittent fasting is useful - especially for the general population who are not very active and struggling with metabolic diseases. However, if you're adding intermittent fasting on top of exercise, you aren't gaining any extra benefits.

❗️ In fact, if you’re a woman, adding intermittent fasting on top of exercise can be harmful to both your performance and your health. ❗️
💥 The threshold for kisspeptin disturbance in women is more sensitive than in men (note: kisspeptin is a neuropeptide, stimulating 2 areas of the hypothalamus in women, but only one in men).

💥 When kisspeptin is downregulated from low nutrient status, the endocrine system takes a hit- there goes the menstrual cycle, and the thyroid starts to downregulate (Hello lowered resting metabolism!) Diets such as intermittent fasting and keto disrupt kisspeptin production.

💥 Adding exercise to the equation just adds to the stress of denying our bodies important nutrient signaling. PS - your body starts storing more belly fat.

💥 The long term effects of intermittent fasting with exercise for women athletes is endocrine dysfunction, increases in abdominal fat, more depression, and subsequent fat gain.
Pretty much the opposite of why you started the diet in the first place, right?
