Is sleep part of your weight loss plan? If not, you could be getting in your own way…
In the pursuit of weight loss, we mainly focus on diet and exercise...but sleep, which plays a vital role in our impulse control, decision making, and motivation is often overlooked.
Even just one night of poor sleep can have you reaching for calorie-dense pick-me-up snacks, or skipping a workout because you don't feel up to it.
In fact, sleep can in many ways make or break a weight loss regimen. And for this reason, I teach all of my clients to treat sleep as one of their non-negotiable "vitamins."
In this article, we explore the profound impact sleep deprivation has on weight loss efforts and practical tips you can use immediately to enhance the quantity and quality of your sleep.
What happens when you don’t get enough sleep:
Disrupted Hormonal Balance:
Poor sleep can disrupt the delicate balance of hormones that regulate appetite, such as ghrelin and leptin.
Ghrelin, known as the "hunger hormone," increases, leading to heightened feelings of hunger and cravings.
On the other hand, leptin, the hormone that signals fullness, decreases, making it harder to recognize when you've had enough to eat.
Consequently, individuals who lack sleep tend to reach for calorie-dense, high-carbohydrate foods as their body seeks quick energy fixes.
Increased Cravings for Unhealthy Foods:
Insufficient sleep often leads to an increase in cravings, particularly for high-sugar, high-fat, and carbohydrate-rich foods.
This can be attributed to the impact of sleep deprivation on the brain's reward center, which becomes hyperactive, leading to a stronger desire for indulgent foods.
As a result, you're more likely to give in to these cravings, consuming excess food and hindering your weight loss progress.
Increased Fat Storage:
Research has found that sleep deprivation can affect blood sugar control and insulin sensitivity.
Elevated blood sugar triggers the release of insulin, which promotes the storage of glucose as fat.
Consequently, those who get inadequate sleep tend to store more fat and have a harder time losing fat due to elevated blood sugar levels.
Reduced Willpower and Motivation:
Lack of sleep compromises the prefrontal cortex, the area of the brain responsible for decision-making and impulse control.
When you're sleep-deprived, you may find it more challenging to resist tempting food choices and stick to your healthy eating plan.
You're more likely to make poor food choices, gravitating towards unhealthy options that undermine your weight loss goals.
Additionally, low energy levels and decreased motivation resulting from poor sleep can make it harder to engage in physical activity and maintain a consistent exercise routine, further impeding weight loss efforts.
6 Practical Tips to Improve Sleep Quality for Effective Weight Loss:
Do a Daily Brain Dump
After a hectic workday, your mind can be filled with unfinished tasks, worries, and lingering thoughts.
By doing a “brain dump” at least 2 hours before bedtime, you transfer these thoughts from your mind onto paper or a digital device, freeing up mental space and relieving the burden of keeping everything in your head.
Write down all your thoughts, tasks, and concerns without judgment or organization. It's a way to empty your mind and declutter your thoughts.
When you do this, you give yourself permission to let go of the day's stressors. It helps you transition from work mode to relaxation mode, allowing you to unwind and mentally disconnect.
This process can help alleviate anxiety and prevent your mind from endlessly replaying work-related thoughts, enabling you to relax more effectively.
Set a Consistent Sleep Schedule:
Establish a regular sleep routine by going to bed and waking up at the same time every day, including weekends.
This helps regulate your body's internal clock, promoting better sleep quality and ensuring you receive the recommended 7-9 hours of sleep per night.
Create a Relaxing Bedtime Routine:
Engage in calming activities before bed to signal to your body that it's time to unwind.
Consider reading a book, taking a warm bath, stretching, practicing relaxation exercises, or listening to soothing music.
Avoid stimulating activities, such as screen time or intense exercise, at least an hour before bed (avoid intense HIIT exercise 3 hours before bedtime).
Optimize Your Sleep Environment:
Create a sleep-friendly environment by ensuring your bedroom is cool, dark, and quiet.
Invest in earplugs, a white noise machine if necessary, or blackout curtains if you live in an urban area with a lot of light pollution.
Body temperature makes a huge difference in sleep quality, so keep the bedroom cool with circulating air.
Additionally, make sure you have a comfortable mattress, pillows, and bedding that support proper spinal alignment.
Limit Stimulants and Alcohol:
Caffeine is helpful for cognitive function early in the day, but can impair deep sleep if taken within 8-10 hours before bed. Even if you don’t have trouble falling asleep after drinking coffee, studies show it can negatively impact quality sleep.
As much as I love wine and cocktails, even 1 alcoholic drink with dinner is enough to impair sleep quality.
While alcohol may initially induce drowsiness, it does disrupt your sleep cycle, leading to fragmented and less restorative sleep.
My recommendation is to stop caffeine consumption at least 8 hours before sleep time and to be selective with evening alcohol (weigh whether that drink is really worth it).
Practice Healthy Sleep Hygiene:
Adopt habits that promote better sleep quality:
Avoid heavy meals close to bedtime (if possible, stop eating 2 hours before bedtime).
Consume a nutrient-rich diet throughout the day. Avoid processed foods.
Limit fluid intake to sips only within the 3 hours before bedtime
Engage in regular physical activity during the day to promote healthy tiredness.
