Are you dealing with constant fatigue, sugar cravings, or stubborn belly fat that won’t go away?
If so, your cortisol levels could be out of balance.
Cortisol is your body’s main stress hormone, and when it stays elevated for too long, it can affect your sleep, mood, digestion, and even your weight.
This 21-day cortisol detox diet is designed to help calm your stress response, nourish your adrenal glands, and give your body the reset it needs in just three weeks.
What Is Cortisol and Why Does It Matter?
Cortisol is produced by your adrenal glands and plays a role in regulating blood sugar, metabolism, and the immune system.
In short bursts, it’s beneficial; it gives you energy to deal with challenges.
But when modern stressors like work deadlines, relationship issues, financial concerns, or lack of sleep keep cortisol high all the time, problems start to show up:
Belly fat that’s hard to lose
Restless nights or waking up exhausted
Afternoon energy crashes
Strong sugar or caffeine cravings
Irritability and mood swings
Digestive discomfort
Weakened immunity
Balancing cortisol through nutrition and lifestyle changes can restore energy, improve sleep, and support healthy weight management.
Why 21 Days?
Research shows it takes around three weeks to form new habits and start seeing hormonal shifts. This program uses that window to help your body:
Remove foods that spike cortisol
Replenish nutrients that support adrenal health
Improve digestion and sleep
Build sustainable stress-management practices
By the end, you’ll feel more energized, clear-headed, and resilient.
How to Prepare for the Cortisol Detox
Before starting, spend 5–7 days setting up your environment and mindset.
Clean Out Trigger Foods
Remove or reduce:
Refined sugar and artificial sweeteners
Processed snacks and fast food
Alcohol
Caffeine overload (coffee, energy drinks)
Refined carbs and gluten-heavy products (if sensitive)
Industrial oils (canola, soybean, vegetable oil)
Stock Up on Supportive Foods
Leafy greens and colorful vegetables
Low-sugar fruits (berries, citrus, apples)
Lean proteins (wild fish, organic poultry, legumes)
Healthy fats (avocados, olive oil, coconut oil, nuts, seeds)
Complex carbs (sweet potatoes, quinoa, oats, brown rice)
Herbal teas and filtered water
Support Tools
Sleep helpers (blackout curtains, white noise app)

Mental Prep
Choose a 21-day period with fewer social events
Write down your “why” for motivation
Let friends or family know (accountability helps)
Take baseline notes on sleep, energy, and mood
Supplements
The right supplements will tremendously accelerate the process for you, but…
…THEY MUST BE BIOAVAILABLE, meaning they are able to be absorbed by your body.
Unfortunately, most of the available brands in the drug stores are not, and it can be a pure waste of money.
So, go for a few targeted supplements. And you only need two of them:
Magnesium, which helps your body relax, supports better sleep, and calms your nervous system. We recommend Double Wood Magnesium Glycinate, which is promotes quick calming effects.
Ashwagandha is another powerful adaptogen that helps calm the nervous system, manage cortisol, and support overall stress relief. WONDER FAMILY Ashwagandha Complex carries one of the most thoughtfully formulated ashwagandha blends available, combining ashwagandha with GABA, L-theanine, and vitamin B6 to lower high cortisol instantly.
