Sugar Detox: What to Do When You’ve Had Too Much Sugar

Need to detox from sugar? Sugar binges happen to the best of us. Birthdays, holidays, Halloween … heck, even just a stressful day can throw you off your clean-eating game into a spiral of candy and sugary treats. Some diets even advocate weekly cheat days to make it easier for you to stick to the diet. The idea is that you can stick it out and eat clean six days a week, and then go crazy on day seven.

Here’s why that’s a bad idea: Your body takes a few days to recover from eating too much sugar, and by the time it’s back to full power, it’s nearly time for you to cheat again. Your brain function will dip and you’ll have background inflammation for most of the week. You may lose weight, but you’ll never end up feeling like the energetic and clear-headed warrior who’s totally on top of their game.

That said, total restriction isn’t the answer either — and when a sugar binge happens, planned or unplanned, you shouldn’t feel bad about it. Delicious food is one of the great pleasures in life. Plus, letting loose now and then reminds you how bad excess sugar can make you feel, and strengthen your commitment to a more healthful diet.

When you do decide to binge on sugar and carbs, use this sugar detox guide to make it easier on your body. These steps will help you recover faster and get rid of cravings, so you can get back to being Bulletproof as quickly as possible.

The sugar hangover: What happens when you eat too much sugar

When you go crazy with the sugar or carbs, you’re going to face some repercussions during the week that follows. That lousy feeling is the culmination of your body’s systems directly responding to your sugar overload. If you pay close attention, you can identify the systems in your body that are struggling — and then take action to help those systems recover. The effects of eating too much sugar can result in symptoms like:

Temporary weight gain

If you’ve ever looked in the mirror after a heavy carb day, you already know about this symptom. You’ll put on a few pounds and look puffier than usual. Don’t panic. The extra weight is mostly water (more on that in a second). It’ll come off when you cut back on sugar and return to your normal diet.

Cravings

Sugar lights up your brain’s reward centers like a Christmas tree, which feels great — until the next day when the sugar runs out and withdrawal settles in.^[1] Sugar hits all the same brain regions that addictive drugs do, and while it’s melodramatic to compare sugar to cigarettes or cocaine, you’ll still have to deal with pretty heavy cravings while your body gets itself back into balance. Read further for a couple of tips to help ease those cravings.

Fatigue

In a small study of lean, healthy young men, refined carbs like sugar were shown to cause systemic inflammation.^[2] This taxes your energy production in two ways. First, rodent studies have shown that sugar impairs mitochondria, reducing the amount of energy cells can produce.^[3] Second, your cells have to spend a lot of their energy dealing with the stress of low-grade inflammation — the result of too much sugar.

Also, in a study of 74 men, sugar was found to cause a sharp decline in testosterone. This drains your energy quickly, leaving you lethargic.^[4] Be ready to weather a couple days of feeling tired. The fatigue will pass once your body repairs itself and you get back to eating better.

Mood swings and headaches

Sugar destabilizes your blood glucose levels and causes withdrawal, leaving you with symptoms like intense cravings and low energy.^[5] A lot of people get headaches, migraines and mood swings, too.

How to prevent sugar crash symptoms

• Drink extra water during your binge: When you eat too much sugar, you pack several hundred grams of it into storage as glycogen. Your body stores at least three grams of water for every gram of glucose you store, which means you’re storing a bunch of extra water with your carbs.^[6] This explains the water weight you put on after eating lots of carbs. You want to drink more water than usual during your cheat day, otherwise you’ll get dehydrated, which can lead to headaches and fatigue.
• Add electrolytes: Bonus points if you add salt and potassium to your water in the week after you binge on carbs. When you return to a low-carb diet, your body will burn through your carb stores and release all the water it took on, and you’ll lose a lot of sodium and potassium with it. Make up for it with salt water and a good potassium supplement to decrease dehydration-related headaches and fatigue.
• Don’t skip meals: It can be tempting to fast the day after a sugar binge. Maybe you want to balance out the extra calories or give your system a chance to get back to baseline. Fasting is good for you for about a dozen different reasons — but on days after you’ve eaten too much sugar, you’re better off eating lots of quality food instead of fasting.
• Stabilize your blood sugar: Sugar throws your blood glucose levels out of whack, resulting in withdrawal symptoms like intense cravings and low energy. This can cause headaches, migraines, and mood swings, too. It’ll take a lot more willpower to stick to a fast the day after you eat a bunch of carbs. You’ll want to eat foods that stabilize your blood sugar so you don’t feel awful and relapse into a second sugar binge. Focus on plenty of vegetables and healthy proteins like pasture-raised eggs and grass-fed beef.
• Eat an anti-inflammatory diet: Your cells will be dealing with chronic inflammation after you overindulge in sugar, and you want to give them the building blocks to repair themselves afterward. Read on for the foods you should eat to manage inflammation.
• Eat at regular intervals: If you’re tempted to fast because you feel guilty about eating lots of sugar the day before, you can fall into disordered eating patterns where you binge, fast and then binge again. That’s not a cycle you want to go down. Listen to your body and eat when hungry, and stop eating before you’re full.

Sugar detox diet: What to eat after a sugar binge

You can eat your way back to balance after a carb binge. Here’s the menu for your sugar detox diet:

Quality fats and proteins

Eat foods like: Grass-fed meat, wild-caught salmon, pasture-raised eggs, coconut oil and MCT oil.

These will fill you up and decrease cravings. They’ll also help you replenish testosterone and other sex hormones that took a hit from all the sugar.

Fiber

Eat foods like: Asparagus, broccoli, carrots, cucumber, celery, leafy greens and sweet potatoes.

To build stable energy and decrease cravings, eat fiber to regulate your blood sugar.^[7] Fiber also feeds beneficial gut bacteria that may have been hurt by sugar. Hit your daily fiber intake by eating your vegetables.

Antioxidants

Eat foods like: Colorful fruits and veggies like red cabbage, Swiss chard, blackberries and raspberries. Drink coffee and green tea for an extra dose of antioxidants, too.

Antioxidant-rich foods will help your body deal with systemic inflammation and repair itself.

Anti-inflammatory foods

Eat foods like: Foods on the green zone of the Bulletproof Diet Roadmap, such as wild-caught salmon, broccoli, avocados and green tea.

To help your body recover from the inflammation caused by a carb and sugar overload, stick to foods that are considered easy for your body to process with minimal potential for inflammation.

Foods that curb sugar cravings

Sugar lights up addictive reward pathways in your brain and will inevitably cause withdrawal and cravings in the days following a binge. Clear your pantry of high-carb snacks to reduce temptation. Instead, stock your kitchen with quality snacks to nip those cravings in the bud before they seduce you into another sugar binge.

Sugar cravings come on fast and sap your energy, so high-fat snacks that you can eat immediately can save the day. A few options are:

• Dark chocolate (78% or darker)
• Grass-fed hot dogs
• Pastured salami or pepperoni
• Guacamole
• Grass-fed meat sticks, jerky or bars
• High-fat nuts like macadamias or almonds, preferably raw

Check out this list of 16 keto-friendly snacks to curb cravings.

Why exercise helps speed up your sugar detox

Even if you feel like a beached whale, do some kind of exercise after eating too much sugar. Hit the gym, do some high-intensity interval training or just go for a long walk. Exercise stabilizes your blood sugar and helps you burn through glycogen stores faster, and psychologically, it helps you get back to your high-performance routine after you break it. It can be tough to exercise during or on the heels of a high-sugar day, but you’ll feel much better afterward.

Above all else, remember that diet exists on a spectrum. You don’t have to eat perfectly all the time. The occasional sugar binge is worth it sometimes. Accept that you won’t feel your best for a couple days afterward and enjoy yourself. And when you do go wild with low-quality food, keep this sugar detox guide handy. It’ll help you get back on your feet as quickly as possible.
