Do you experience tingling in your hands, sharp pain shooting down your legs, or numbness in your feet? These could be warning signs that your body is desperately lacking essential vitamins, particularly vitamin B1. Dr. Eric Berg DC, a renowned expert in healthy ketosis and intermittent fasting, explains that vitamin deficiencies are behind most nerve problems, with B1 deficiency being the most common culprit. "The most common nerve problem that exists is something relating to either prediabetes or diabetes," says Dr. Berg. Learn how to identify these warning signs and discover the simple solutions that could reverse your nerve damage and help you live pain-free.


Warning Sign 6 Viral Nerve Pain After Stress

Certain viruses can hide in nerve bundles called ganglia, explains Dr. Berg. "What's unique about these viruses is they go into those areas, those little bundles, to evade the immune system and fly underneath the radar," he notes. These viruses can deactivate autophagy—your body's natural recycling system for damaged proteins and pathogens.

Stress Triggers Hidden Viruses

According to Dr. Berg, these dormant viruses often emerge after stressful events. "Cortisol is an immune suppressant. One of the most severe stresses someone can go through is emotional stress. This is why a lot of these dormant viruses come out of remission after a stress event," Dr. Berg explains.

Fight Viruses With This Amino Acid

There's an important relationship between two amino acids that can help combat these viruses. "These viruses need the amino acid called arginine to exist. And it just so happens that arginine competes with another amino acid called lysine," says Dr. Berg. If you supplement with enough lysine, you can block arginine and stop viral reproduction.

How Much Lysine You Need Daily

Dr. Berg recommends: "You have to take a lot of lysine to compete and block arginine. You want to take 1000 milligrams to 3000 milligrams every single day for a period of time to put that virus back in remission, as well as do whatever you can to reduce stress."

Sciatica pain usually originates from disc issues, and Dr. Berg has identified a common deficiency in these cases. "A lot of people with disc problems are deficient in copper," he states. For relief, Dr. Berg suggests "either taking a supplement with copper or just putting copper cream topically around that area in your back where it originates to reduce the discomfort."

Warning Sign 3 Wrist Pain and Weakness

For the common wrist condition known as carpal tunnel syndrome, Dr. Berg points to a specific B vitamin deficiency. "This is usually a B6 deficiency," he explains. Addressing this specific deficiency can help relieve pressure on the median nerve in the wrist.

The protective sheath around your nerves requires specific nutrients to stay healthy. "If you're deficient in B12, you can get electric shock-like sensations in your nervous system, very painful or even numbness," says Dr. Berg.

Your Nerve's Protective Coating

Dr. Berg explains why this happens: "B12 is involved with the myelin sheath around the nerve. That's the outer covering that protects the nerve, insulates it, and allows the signals to transmit."

Autoimmune Conditions and Vitamin D3

For autoimmune conditions affecting the nerves like Multiple Sclerosis (MS), Dr. Berg recommends a specific vitamin. "Vitamin D3 is essential in reducing inflammation within the nerve cells and also your brain cells," he states.

High-Dose Vitamin D3 Strategy

The dosage needed may be substantial. "You need to take large amounts of vitamin D3, 50, 60, 70, 80,000 IU of vitamin D3 to put that condition into remission," according to Dr. Berg, who references the Coimbra protocol for this approach.

The 1 Vitamin for Nerve Health

The most common nerve problems are related to high blood sugar levels. "A lot of people with diabetes end up with nerve problems in their feet. They get numbness in the toes first, and then it kind of starts traveling in the foot," Dr. Berg explains.

What's causing this damage? "The sugar in the blood is creating such a demand for this one vitamin. That vitamin is called vitamin B1, thiamine," says Dr. Berg.

Why B1 Is Critical For Nerve Health

Dr. Berg clarifies the relationship between diet and this deficiency: "The more carbohydrates or sugar someone consumes, the greater the need for B1. If you're prediabetic or diabetic, you have a lot of sugar going through the bloodstream. That means you're going to need even more B1 to compensate."

Try This Special Form of B1

He specifically recommends a form called benfotiamine: "I would take it in the form of benfotiamine because that tends to penetrate the myelin and get right into the nerve and very quickly reverse nerve damage that's caused from high sugar."

For B1 to work effectively, Dr. Berg points out another crucial nutrient: "In order for B1 to work, there's another cofactor that you need and that's magnesium." This mineral works synergistically with B1 to support proper nerve function and health.

Think you're getting enough protein? Many of us don't, and the signs aren't always obvious. In this revealing countdown, we'll explore ten increasingly important signs of protein deficiency, starting with subtle hints and building up to serious warning signals that demand attention.

Dr. Ken Berry, a family physician with over 20 years of clinical experience, brings crucial insights about protein deficiency that could transform your health. As he explains, "There are sources of information out there that will tell you that eating too much protein is bad for you... In fact, nothing could be further from the truth." Join us as we count down these essential warning signs that could help you identify and correct this common deficiency.

Sleep Disruptions – The Surprising Sign

The countdown begins with an unexpected connection. Dr. Berry shares his own surprise at this finding: "When I was doing the research for this video, I did not know that a protein deficiency can lead to insomnia, but it's actually quite well known in the sleep literature," he says in his video post.

Mood Changes

Your protein intake might be affecting your emotional well-being more than you realize. As Dr. Berry notes, "If you're always down in the dumps, you always have a negative mood, this is actually a sign of protein deficiency."

Unusual Cravings and Hunger

Those persistent cravings aren't random. Dr. Berry explains, "Your body's looking for a very short list of nutrients in your diet. It's looking for amino acids that come from protein... If you're not getting enough protein in your diet, then your body is going to increase your hunger and it's going to make you have these weird cravings trying to get the particular amino acid or protein molecule that it's looking for."

Brittle Hair, Nails, and Skin Issues

Physical appearance often reflects internal nutrition. Dr. Berry warns, "If your skin is dry and flaky and very thin, if your nails break very easily or they flake up very easily, if your hair's brittle and breaks, if you're having hair loss for no apparent reason, these are all signs of protein deficiency."

Slow-Healing Wounds

Scars on the faceShutterstock

Notice how long it takes for cuts and scrapes to heal? Dr. Berry points out, "If you've been eating low protein for years or decades, then you've gotten used to how long it takes for your wounds to heal, so you may not recognize your wound healing as slow, so maybe ask some friends and relatives how long it takes for a scrape or a cut or an abrasion to heal."

Frequent Infections

Your immune system needs protein to function properly. Dr. Berry explains, "If you have frequent upper respiratory infections or frequent bladder infections or frequent skin infections... Your immune system has to have a lot of protein in order to fight off infections, whether we're talking about bacterial infections or viral infections."

Stunted Growth in Children

For children, protein deficiency can have lasting consequences. "Stunning growth is almost always due, at least in part to a protein deficiency," Dr. Berry emphasizes. "The child just not getting enough protein... if you want your child to grow up to be tall and strong and beautiful and intelligent, they've got to get enough protein in their diet."

Muscle Loss

Muscle health is a crucial indicator. Dr. Berry states, "A very common sign of protein deficiency is muscle loss or the inability to gain muscle. This is very common in the elderly. As they don't eat enough protein, they lose their muscle mass. In some athletes, if they're not eating enough protein, they work out really hard and they don't gain muscle at all."

Decreased Bone Strength

This sign challenges common misconceptions. Dr. Berry explains, "Most people think bones are made of calcium. They're actually made of protein with a calcium atom stuck into the matrix of the protein. Your bones are all protein, and if you're not eating enough protein, your body will not be able to keep your bones strong."

Severe Edema

In advanced cases, protein deficiency can lead to visible swelling. Dr. Berry warns, "If you have a severe terrible protein deficiency, you can actually develop edema or swelling in your ankles and feet. This is kind of an end stage sign when you've been protein deficient for so long that your body's about to give up."

Expert Recommendations: Getting Enough Protein

Dr. Berry recommends focusing on whole food sources: "The best sources for protein that I recommend are meat, fish, eggs, and cheese." He specifically notes, "Never ever do you need a protein shake or a protein bar or a protein powder. Those are usually wind up being carbohydrate shakes in bars and powders."

For optimal intake, he advises "two grams of protein per kilogram of body weight, or if you're in the United States, then one gram of protein per pound of body weight." He emphasizes that this isn't excessive: "Protein's good for your kidneys, protein's good for your bones. Protein is good for every other part of you."


Special attention should be paid to at-risk groups: elderly individuals who might default to simple carbohydrates, women (especially during pregnancy and breastfeeding), and growing children who might prefer snacks over protein-rich foods.

The most popular supplement in America isn’t Vitamin C or a multivitamin—it’s Vitamin D. Vitamin D regulates your calcium levels, vital for healthy bones, and facilitates normal immune system function. So how do you know if you need it too? “Lack of vitamin D is not quite as obvious in adults,” says the Cleveland Clinic. “Signs and symptoms might include” the following.


You Might Feel Fatigue

“Vitamin D deficiency is frequent and has been associated with fatigue and other unspecific symptoms including headache, musculoskeletal pain and weakness, depression, and impaired cognitive performance,” says one study published in Medicine. “Vitamin D treatment significantly improved fatigue in otherwise healthy persons with vitamin D deficiency.”

You Might Feel Bone Pain

“Vitamin D status influences musculoskeletal health,” says one study published in Musculoskeletal Medicine. “Low vitamin D levels may lead to clinical manifestations, including bone pain, muscle weakness, falls, low bone mass, and fractures, with subsequent diagnoses of osteomalacia, osteoporosis, and myopathy.”

You Might Feel Muscle Weakness, Muscle Aches, or Muscle Cramps

“Vitamin D is increasingly recognized to play an important role in normal muscle function,” say the authors of one study published in Bone Reports. “Low vitamin D status is associated with an increased risk of falls and proximal weakness. Since vitamin D deficiency is very common, and the signs are non-specific, it is important to maintain a high index of suspicion of vitamin D deficiency in patients with muscle pain and weakness.”

You Might Have Mood Changes, Like Depression

“Depression in its own right is a disabling condition impairing all aspects of human function,” say the authors of a study in Issues in Mental Health Nursing. “In persons with a chronic medical disease, depression often makes the management of chronic illness more difficult. Recently, vitamin D has been reported in the scientific and lay press as an important factor that may have significant health benefits in the prevention and treatment of many chronic illnesses. Most individuals in this country have insufficient levels of vitamin D. This is also true for persons with depression as well as other mental disorders.”

If You’re a Child, You Could Get Rickets

“Severe lack of vitamin D causes rickets, which shows up in children as incorrect growth patterns, weakness in muscles, pain in bones and deformities in joints,” says the Cleveland Clinic. “This is very rare. However, children who are deficient in vitamin D can also have muscle weakness or sore and painful muscles.”

“Your doctor can order a blood test to measure your levels of vitamin D,” says the Cleveland Clinic. “There are two types of tests that might be ordered, but the most common is the 25-hydroxyvitamin D, known as 25(OH)D for short. For the blood test, a technician will use a needle to take blood from a vein. You do not need to fast or otherwise prepare for this type of test.” And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.

It might seem counterintuitive, but in order to lose fat, you have to eat it. However, not all fats are created equal. Claire Sorlie (@clairethenutritionist) is a Certified Nutritionist, NTP, BFA, who specializes in gut health. In one of her many viral videos, she explains why you need to incorporate them into your diet. “There's another reason why healthy fats are our friends, and they shouldn't be feared from a nutritionist,” she says in the viral TikTok clip. We also consulted The Body Network’s Resident RDN, The Diet Diva, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian, to weigh in on her tactics.


The Body Needs Vitamins A, D, E, and K

Claire_Sorlie_clairethenutritionist5clairethenutritionist/TikTok

She starts off by explaining the nutrients necessary for health. “Four really important vitamins that the body needs are vitamins A, D, E, and K,” Claire says.

They Are Fat Soluble Vitamins

Interestingly, in order to work, vitamins need fat. “These are also our fat soluble vitamins, which means that they need a fat in order to be absorbed and used in the body,” she continues. “These vitamins are literally designed to work properly with a fat.”

If You Don’t Consume Enough Fat, the Body Won’t Absorb Nutrients

If you are on a low-fat or nonfat diet, you might be missing out. “If we're consuming a low fat diet or having a nice big salad with no fat, the body may not absorb any of those nutrients,” she adds.

These Vitamins Are Important for Heart Health

Why are those vitamins so important? “A, D, E, and K are all important for things like our cardiovascular health, immune health, mental health, and bone health,” Claire says.

Tara_Collingwood2Diet Diva/Facebook

Collingwood confirms that fats are necessary for your body to absorb vitamins. “These Vitamins are classified as fat soluble vitamins which means they do need some fat in the diet to be properly absorbed, ideally at the same meal,” she explains. “Vitamin E is often found in foods that already contain some fat like nuts and seeds, but Vitamin A and K are found in fruits and veggies.” She suggests aiming to have a little bit of good fat at every meal.

Ever feel exhausted despite getting enough sleep? Notice your workouts taking longer to recover from? These could be your body's way of saying you need more protein. While severe protein deficiency is rare in developed countries, even mild insufficiency can impact your daily life and long-term health.


As a holistic health expert and former Olympic athlete, Dr. Sten Ekberg brings a unique perspective to nutrition and wellness. With his background in functional medicine and chiropractic care, combined with his experience as a Swedish national record holder in decathlon, he helps people understand their body's signals and optimize their health through proper nutrition.

Here are the key signs that might indicate you need more protein in your diet.

Your Muscles Are Sending Warning Signals

"Muscle-related issues are often the first sign of protein deficiency," says Dr. Ekberg in his post. He explains that weakness, slow recovery after workouts, and muscle cramps can all indicate low protein levels. "Your muscles are primarily made of protein. Without enough, you can't repair muscle fibers or regulate electrolytes properly, which can lead to cramping."

Wounds Take Longer to Heal

Protein plays a crucial role in healing. "Most tissue in your body is made up of protein," Dr. Ekberg notes. "When you're low on protein, wound healing can slow significantly because your body lacks the building blocks for repair."

Your Hair, Nails and Skin Are Suffering

"Keratin and collagen are the two main proteins that keep your hair, nails, and skin healthy," Dr. Ekberg explains. "Without adequate protein intake, your body can't produce enough of these structural proteins." Watch for weak, brittle nails, thinning hair, and dry, flaky skin – all potential signs of protein deficiency.

Digestive Issues Are Becoming Common

Most people don't realize that digestion relies heavily on protein. "Every digestive enzyme in your body is made from protein," Dr. Ekberg points out. "From the amylase in your mouth to the enzymes in your intestines, protein deficiency can compromise your entire digestive process."

You're Getting Sick More Often

"Your immune system depends heavily on protein," Dr. Ekberg emphasizes. "Antibodies that fight infection are actually large protein molecules. When you're low on protein, your body struggles to produce enough antibodies and white blood cells to maintain strong immunity."

Your Hormones Feel Out of Balance

mid adult italian woman banging her head against a wall outside office building. Horizontal shape, copy spaceShutterstock

Dr. Ekberg notes that many essential hormones – including insulin, growth hormone, and thyroid-stimulating hormone – are made of protein. "When protein levels drop, hormone production can be disrupted, affecting everything from your metabolism to your stress response."

Fatigue Has Become Your New Normal

"Protein deficiency can cause fatigue in two ways," Dr. Ekberg explains. "First, hemoglobin, the protein that carries oxygen in your blood, may decrease, leading to anemia. Second, the enzymes that regulate energy production require protein to function properly."

Brain Fog Is Affecting Your Focus

Mental clarity can suffer when protein is low. "Your brain relies on protein-based neurotransmitters to function properly," says Dr. Ekberg. "Without enough protein, you might experience brain fog, difficulty concentrating, and mood changes."

Your Bones and Joints Are Weakening

"Many people are surprised to learn that bone is 30% protein," Dr. Ekberg reveals. "The protein matrix must be strong before calcium can properly mineralize it. Low protein intake can lead to weaker bones and joint problems over time."

You're Experiencing Fluid Retention

"Albumin, the most abundant protein in your blood, helps maintain proper fluid balance," Dr. Ekberg explains. "When protein levels drop, fluid can leak into surrounding tissues, causing swelling and puffiness, particularly around the ankles and knees."

How Much Protein Do You Really Need?

The daily protein requirement varies based on age, weight, and activity level. While the basic recommended dietary allowance is 0.8 grams of protein per kilogram of body weight, many experts now suggest this might not be enough, especially for older adults. Dr. Michelle Oppezzo, a nutrition expert, recommends "between 1.2 to 1.6 grams per kilogram of body weight for adults over 50, which is roughly double the federal recommendation."

Optimizing Your Protein Intake

Getting enough protein isn't just about the total amount – timing matters too. "Aim for 0.4 grams of protein per kilogram of body weight at each meal," Dr. Oppezzo advises. For a 165-pound person, this translates to about 30 grams of protein per meal. Research supports spreading protein intake across three daily meals, with 25-30 grams of high-quality protein at each sitting for optimal muscle health and nutrition.

Remember, while these signs might indicate protein deficiency, they could also stem from other causes. If you're experiencing any of these symptoms, consult with a healthcare provider for proper diagnosis and treatment. Focus on incorporating a variety of protein-rich foods into your diet and consider your individual needs based on your age, activity level, and overall health status.

Are you weighing yourself at all the wrong times? It’s likely, according to one expert. Dillon Swinney is an online fitness coach who helps his clients burn fat and build lean muscle by eating foods they love. In a new post, he reveals the “5 worst times to weigh yourself” on a calorie deficit. “Weighing yourself can be one of the easiest ways to measure progress, but it doesn’t always tell the full story—especially when you’re in a calorie deficit. Here are 5 times to avoid stepping on the scale,” he writes. He also reveals the best time to step on the scale.

1. After Eating a Lot of Carbs

The first time you should avoid weighing yourself is after eating a lot of carbs. “Carbs can cause your body to retain water. For every gram of carbs you consume, your body may store 3-4 grams of water. If you’ve had a carb-heavy meal, don’t stress about the scale going up—it’s temporary water weight,” he says.

2. After Eating Salty Foods

The next time you should avoid jumping on the scale is after eating a lot of salty foods. “Foods that are high in sodium can make your body hold onto water, causing a temporary weight gain. If you’ve had salty foods or fast food, your body might be holding onto 2-4 lbs of extra water weight. This will drop off after a couple of days,” he says.

3. After a Hard Workout

It might be tempting to weigh yourself right after exercising, but he doesn’t recommend it. “Post-workout, your muscles can be swollen from exertion and may hold on to fluids. This temporary weight gain is nothing to worry about—it’s not fat, just muscle repair and water retention,” he says.

4. When You’re Stressed or Anxious

Another situation in which you should avoid the scale? When you are stressed or anxious. “Stress can elevate cortisol levels, which may cause your body to hold onto extra water. If you’ve had a stressful day, your weight could be up, but it’s not reflective of your fat loss progress,” he writes.

5. When You Haven’t Had Enough Sleep

If you didn’t sleep last night, you shouldn’t weight yourself. “Lack of sleep can affect your body’s metabolism and water balance, leading to temporary weight fluctuations. If you haven’t slept well, it can show up on the scale, even if you’re still in a calorie deficit,” he says.

Here Is When You Should Weigh Yourself

So when should you weigh yourself? “For the most consistent readings, weigh yourself first thing in the morning after you use the bathroom, before eating or drinking anything,” he says. “Remember, the scale doesn’t define your progress. Stay consistent with your efforts and look at the bigger picture.” And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.

Eat Like This

“Build each meal around protein because it will help you lose fat while building lean muscle,” he says, revealing his grocery list:

  • 2 cartons of eggs
  • 1 whole chicken
  • 2 steaks
  • 2-3 lbs of ground beef
  • Colorful veggies
  • Potatoes
  • Greek yoghurt
  • Berries.

Drink More Water

Next, amp up hydration. “Dehydration leads to low energy, hunger, and overeating,” he says. “Try this: Keep a water bottle visible and within reach as a visual reminder. Drink 500 ml to 1 L of water 1 hour before your first cup of coffee to allow your natural cortisol levels to rise. Drink at least 2 L of water daily: 1 L before lunch and 1 L in the afternoon.”

Lift Weights 3 Times Per Peek

Next, strength train and lift weight three times a week. “Strength training boosts your metabolism, builds muscle and makes you look better fatter,” he says. “Do this: Focus on compound exercises that target multiple muscle groups. Lift heavy weights to build strength and muscle. Push to 1-2 reps from failure each set.”

Go to Bed Early

Next, prioritizer sleep. “Sleep is your fat-loss cheat code. It helps you build muscle, avoid late-night snacking, and feel less hungry the next day,” he says, suggesting the 10-3-2-1-0 Sleep Rule.

10 hours before bed: No caffeine.

  • 3 hours before bed: No food or alcohol.
  • 2 hours before bed: No work.
  • 1 hour before bed: No screens.
  • 0 times to hit snooze.

Don’t Cut All Your Favourite Foods

In a new post, he reveals how to enjoy food at your favorite restaurant while losing weight. “5 rules to eating at restaurants when you are trying to drop body fat. These are a game-changer,” he writes.

Share Dishes

“Share Dishes” is rule number two. “Instead of ordering multiple entrees for yourself, consider sharing dishes with your dining companions. This not only allows you to enjoy a variety of flavors but also helps control portion sizes and prevents you from overindulging,” he says.

Choose Healthier Options

Rule three? “Choose Healthier Options,” he instructs. “Opt for grilled items instead of fried ones, and choose dishes that include plenty of vegetables. Healthier choices often contain fewer calories and can provide more nutrients, helping you feel satisfied without excessive calorie intake,” he says.

Mindful Eating

Mindful eating is the next thing you need to do. “Take your time to savor each bite, chew slowly, and be aware of your hunger cues. Mindful eating can enhance your dining experience and help you recognize when you’re actually full, preventing you from eating more than necessary,” he says.

Limit Appetizers and Sides

The last rule? “Limit Appetizers and Sides,” he says. “While chips and salsa and bread and butter are tempting, it’s easy to overeat them before the main meal arrives. Set a limit for how much you will indulge in starters and consider skipping them altogether or opting for a small portion. CHIPS AND SALSA, guacamole are my favorite!”
