Afternoon SlumpWhen it comes to the dreaded afternoon energy slump, most people have come to think of it as a daily rite of passage. But that simply doesn’t have to be the case. Not only can you minimize that energy-depleted feeling , you can prevent it with a few simple steps that don’t include caffeinated beverages or mid-day snacking.


What Causes the Afternoon Slump?

If you had a high-carbohydrate lunch, the calories you consumed increased your blood sugar and spiked your insulin. This gives you a burst of energy, but soon after, your insulin levels plummet and you feel tired. Your core body temperature drops in the afternoon too, stimulating the release of melatonin, the chemical in your brain that causes a feeling of tiredness and encourages you to sleep. And the more you slow your own physical activity to compensate for the fatigue, the less you’ll burn those available carbohydrates and the sleepier you’ll become.


Why Fewer Carbs Equals More Energy

Carbohydrates are present in most foods. On The Paleo Diet®, we get them in fruits and vegetables, and in starchy foods like sweet potatoes, plantains, chestnuts, and some squashes. But when it comes to carbohydrates—eating less equals longer-lasting energy.

A carbohydrate-rich breakfast is going to give you a boost of energy in the morning, but by spiking your insulin to cover that rise in blood sugar, it will burn off quickly and have you starving well before lunchtime. Your increased appetite is going to push you toward eating more high-carbohydrate foods to recover, and the cycle will repeat again causing the dreaded mid-afternoon slump. If you want to avoid the crash, cut back on those morning carbs so you’re burning mostly fat and not sugar for fuel. Keep your lunch carbohydrate intake low as well. Here are the top four steps to stomping out the afternoon slump:

1. Breakfast Calorie Burn

Breakfast is one of the joys of a Paleo diet, but to avoid that afternoon slump keep your starch and sugar intake to a minimum in the morning. Sweet potatoes, plantains, and acorn squash are all healthy food choices, but they will fuel the cycle of blood sugar spikes and energy crashes throughout your day if you eat them in the morning. So, limit your serving size, or better yet, save them for your last meal of the day when feeling relaxed and sleepy can be productive in promoting a good night’s sleep. Instead, focus on high-quality protein, healthy fats, and colorful vegetables for breakfast and lunch meals.

2. Hydrate, But Not with Caffeine

Hydrate, but not with caffeine. Water not only reduces fatigue, it helps your body excrete the byproducts of metabolism and lubricates your joints, and aids in digestion, circulation, pain tolerance, and brain function. Drink before you’re thirsty, because by the time your body signals your need for fluids, you’ll already be dehydrated. And, as already mentioned, avoid caffeinated beverages, because caffeine is a diuretic and can, therefore, lead to more dehydration.

3. Exercise for Efficiency

Exercise helps stabilize blood sugar levels for about 24 hours by increasing your muscle cells’ ability to take up glucose. So, your muscles are able to burn the carbohydrates in your food more efficiently. This can help reduce the insulin spikes and drops that can lead to afternoon sleepiness. Fat doesn’t need insulin, and less insulin mean less hunger and more energy.

4. Sleep Like It’s Important—Because It Is

Sleep influences how your body regulates blood sugar. According to the National Institutes of Health, “two hormones that play a major role in appetite regulation—leptin, a satiety hormone, and ghrelin, a hunger hormone—are influenced by sleep.” Make sleep a priority. The better you sleep at night, the more energy you’ll have during the day, the less likely you are to get sick, and the more stable your hormones. Develop a routine of winding down before bedtime and stick to your plan.

By consuming a healthy Paleo diet, the dreaded afternoon energy slump you’ve come to except on a daily basis will be eliminated from your routine. Living a Paleo lifestyle will feed your body for productivity, and support steady energy throughout your day.

Sleep | The Paleo Diet
As we move into the colder, darker and shorter days of fall and winter it becomes more difficult to maintain your energy levels, productivity and fight off nasty colds and flu. These common complaints become the norm as the seasons change and people are constantly looking for that “magic bullet” supplement or medication to keep them running on all cylinders. Interestingly, a new study on the daily patterns of modern hunter-gatherer tribes across the globe might hold a few clues in how we can keep ourselves healthy, fit and productive through the winter season.

How Much Sleep Did Our Paleo Ancestors Really Get?

There is a romantic notion that our “hunter-gatherer” ancestors rested their heads with the setting sun in the evening, slept blissfully through the night for 8-10 hours and woke up with the rising sun. They certainly didn’t have cellphones, laptops or external light sources to keep them up. Was it partly down to this that they were so fit, strong, and free of chronic degenerative diseases? Not quite.

An interesting new study on modern day hunter-gatherer tribes – the San of southern Africa, the Tsimane in Bolivia, and the Hadza in Tanzania – found they only sleep an average of 5.7-7.1 hours per night.1 This is very surprising because sleep research today suggests most westerners are sleep deprived, averaging about 6.5 hours of sleep per night, which is approximately 1.0-1.5 hours less sleep than our grandparents got two generations ago. Experts believe we should be aiming for 7.5-8.0 hours per night for better health.

This new research suggests there is much more at play than simply the amount of hours of sleep you get (although, I believe this is also important). Let’s take a closer look at some key factors that could help you improve your sleep and upgrade your energy levels this winter and help fight off colds and flu.

The Tribes Go To Bed Earlier in the Winter

As the year comes to an end, most people are busier than ever at work and home as the holidays approach, rather than winding down to recharge their batteries. If we look to our ancestral roots to find answers to the “best” sleep practices, we find the tribes in the aforementioned study went to bed earlier during the darker days of winter/rainy season and later in the summer/dry season. Their average bedtime was just after 9:00 pm in the winter months, compared to 10:45 pm in the summer (still, not exactly “night owls” by today’s modern standard).
A lot people struggle to get bed before midnight (laptops, cellphones and TVs don’t help) and usually don’t get to bed earlier in the colder, darker, winter months. As we approach the darkest days of the year, we should be getting more sleep (not less), but holiday parties, travel, and work commitments usually ramp up at this time of year. This lack of sleep is shown in the research to suppress your immune system function, putting you at significantly increased risk of catching a cold or flu.2

The Tribes Wake Up Consistently With Morning Light

Hitting snooze is a morning ritual for a lot of people, as they struggle to find the energy to get out of bed and start their day. While I am sure we can all agree that sleeping in feels pretty good, is it what your body really needs? The tribal groups in this study woke up at virtually the same time throughout the entire year with the morning sun (not surprising if you’re an avid camper!).

Many of your key hormones are produced on a natural daily pattern or circadian rhythm that new research shows gets disrupted if you constantly change your sleeping and waking time. Disrupted circadian patterns have been shown to leave you more prone to fatigue (sound familiar?), inflammation, and even change the balance of “good” to “bad” bacteria in your gut.3

If you struggle with fatigue, insomnia or frequent colds and flus, aim to have a consistent bedtime and waking time this winter. Go to bed earlier (don’t sleep in longer in the mornings) to help kick your snooze button habit in the morning. If you really struggle to wake up, try some gentle stretching/mobility/yoga on the floor to ease your way into the day. (Not only that, research shows the later you get to bed the greater your likelihood for weight gain.4 If weight loss is also a goal, get ahead of your new year’s resolution by tucking in earlier at night).

The Tribes Are Exposed To Lots of Morning Light

It’s difficult to wake in the morning and get outside during the cold days of winter. Fatigue, lack of time and general desire to stay warm keep you huddled up in your house, car, and office. However, not exposing yourself to natural light may be having a significant negative impact on your health.

Modern hunter-gatherer communities get up daily with the morning sun and engage in the vast majority of their physical labor in the morning hours exposed to natural light. In contrast, most people are indoors all morning throughout the winter – commuting in cars and working in buildings – not getting nearly enough exposure to natural light. Even on a cloudy day, the natural light outside provides a whopping 100,000-lux (a measure of light intensity), compared to only 5,000-lux in your office or home.

New research shows that this light exposure is crucial for circadian hormone production and thus your energy levels, health and resiliency.5 It’s easy to find yourself stuck in your car, office or house all winter. Instead, get outside to grab your morning coffee, walk a few blocks to your next meeting, or go outdoors in the morning for a light run/jog to start your day. You’ll feel much better for it!

Often we’re drawn to the “shiny new toy” or exotic and complex solutions to our problems, however the real lasting solutions are typically always found in how you eat, move and lifestyle factors. While a Paleo diet will go a long way to keeping you energized and fighting off colds and flu this winter (check out my article on how to Paleo boost your immunity this fall), looking at your daily patterns of sleeping and waking from an ancestral perspective will likely help you dramatically upgrade your energy and vitality this winter.

All Day Energy Cherry Mint Turkey Balls

Turkey is a great source of protein and high-quality fat. Paired with steamed vegetables or a fresh, garden salad, our Cherry Mint Turkey Balls offer enticing flavors and clean-burning, all day energy.

Wait a second. Doesn’t eating turkey induce sleepiness? This urban legend, most likely inspired by our inclination for napping after Thanksgiving meals, actually has nothing to do with turkey, and much more to do with overeating.

If you’d like to impress your friends with your knowledge of amusing, overly technical scientific jargon, the scientific term for food-induced drowsiness is postprandial somnolence. You might try informing your boss some day that you’ll be away from your desk while you sort out some postprandial somnolence issues. If you say it with enough confidence, it just might work.

Turkey contains tryptophan, an essential amino acid that is the precursor to serotonin and melatonin (by way of serotonin), the neurotransmitters that regulate sleep.1 However, turkey isn’t any higher in tryptophan compared to related foods.

25 g of turkey protein contain 284 mg of tryptophan. You would consume 25 grams of protein from a serving of meat weighing between 100 and 150 grams. Leaner cuts have more protein; more fatty cuts have less. 25 g of beef, lamb, pork, and chicken protein contain 280 mg, 292 mg, 318 mg, and 292 mg of tryptophan, respectively.2 In other words, all types of meat have very similar tryptophan levels.

Interestingly, research shows that high-carbohydrate meals increase serum tryptophan concentrations, whereas meals of protein plus fat have the opposite effect.3 So be careful. If your boss knows you’re eating Paleo, he/she might also know your postprandial somnolence issues are completely unfounded.

Get Rid of Bloating And Lose Weight | The Paleo Diet

Dr. Cordain,

I found your book, suggested to me by Dr. Valori Treloar (Dermatologist and co-author of The Clear Skin Diet), to help me with weight loss and lowering my insulin resistance (precursor to diabetes.) I have been following The Paleo Diet for about six months. It was suggested by Dr. Treloar during an appointment, to perhaps change some foods and eliminate others to improve my condition. I immediately purchased your book and found it to be extremely easy to read and to understand your suggestions on food choices and preparations. I was trying to become a vegetarian and introduced beans to replace meat dishes. Although tasty, I was very bloated and not losing pounds or inches. So, I followed your food lists, your recipes, your exercise suggestions and found myself feeling less bloated and more energetic. It is important to begin to feel better to then continue on an exercise routine. In my case, I ride the stationary bike because of knee issues and use the treadmill with caution.

The first couple of days eating the Paleo way, I Iost fluids and as well as my bloated feeling. This felt good. I have so many food choices, I never go hungry. I found vegetarian fed chicken and beef easily in the markets. My quarter cup of walnuts came in handy either on diced apple with cinnamon for breakfast as an alternative to egg white, veggie omelets or a couple of hard boiled eggs (Egglands Best, of course with extra omega-3.) Fruit is a favorite for me, so no problem having a serving with each meal or snack. Veggies are so easy to use in meal planning. I just make sure to buy lots of them at the market in winter and now at farm stands in summer here in the Northeast.

So now for the results: several doctors have confirmed my weight loss which has been gradual. About eighteen pounds in six months, (on Paleo Diet) but actually twenty-five in one year, struggling with the traditional food pyramid. Definitely the Paleo Diet is better for me dealing with the inflammation I had in my body, the fluid retention and lack of energy. I do not weigh myself daily, but I feel my clothes fitting better and actually some are too big for me. I began to see changes in my face becoming thinner, my neck thinner, my upper back thinner, my waist slimming and changes in my legs – less fluid around the knees and ankles.

One very interesting fact appeared about a month into eating the Paleo way. While exercising on my stationary bike, I had a burst of energy and stayed on it for a longer time. It felt good. I now split time on my stationary bike and the treadmill (no inclines because of my knee issues). I am able to walk longer distances outside as long as I avoid hills. It feels great to be able to enjoy being outdoors again. I also found doing tasks around my home taking less effort and my mental attitude is more positive. I am willing to take on a task and complete it. This motivates me to accomplish more during a daily routine. I work from home and my mental attitude is improved.

I will continue eating the Paleo way and suggest your book to others who find themselves unmotivated to lose weight. I enjoy the flexibility of this eating style and know when I eat foods not on the list, I feel bloated and sluggish. There are times when I do crave grains, but definitely I am in control and stay within Paleo guidelines most of the time. I do not deny myself from cravings and when not eating the Paleo way 100% each week, I find it very easy to get back on track. The slimmer me and good, healthy feeling I have, is the motivation to stay with this nutrition plan.

Thank you so much for making your book easy to understand and helpful with food lists. Your menu selections are helpful to get started and I now create my own dishes. By the way, my husband eats the Paleo way since I do the cooking most of the time. He lost ten pounds without extra exercise. We both feel much better eating the Paleo way.


Energy Levels | The Paleo Diet

I keep to the diet, but for two cups of coffee with skim milk a day. My lipids were all good. My energy level is better (it was good before), yet I sleep one hour more each night. At this point I like it and I am staying on it. Thank you for writing your book.
