Are you deficient in essential vitamins? “There are many telltale signs of vitamin and mineral deficiencies,” Patricia Graham, MD, tells RUSH University Medical Center. “But the good news is that often, if you take steps to address the deficiency, the symptoms will either improve or go away altogether. Communicating your concerns with your primary care doctor is essential. That way, we can check out your issue and reverse the problems early on. Often, the treatment for these deficiencies is fairly simple, so the key is identifying them." Here are the top 9 vitamin deficiencies and how to spot them.


Vitamin Deficiency Anemia

Vitamin deficiency anemia can cause dizziness and fatigue. “Vitamin deficiency anemia is a lack of healthy red blood cells caused by lower than usual amounts of vitamin B-12 and folate,” says the Mayo Clinic. “Symptoms can include fatigue, shortness of breath and dizziness. Vitamin supplements, taken by pill or injection, can correct the deficiencies.”

Calcium Deficiency

If you feel constant aches and pains in your bones or trouble with chest pains, you may have a calcium deficiency. "Calcium regulates your heartbeat," Dr. Graham says. "So a deficiency could cause an arrhythmia, or irregular heartbeat, and even lead to chest pains."

Vitamin D Deficiency

Vitamin D deficiency can cause both physical and mental issues. “When vitamin D levels are low, and the body isn’t able to properly absorb calcium and phosphorus, there is an increased risk of bone pain, bone fractures, muscle pain, and muscle weakness,” according to Yale Medicine. “In older adults, severe vitamin D deficiency (levels less than 10 ng/mL) may also contribute to an increased risk of falls."

Vitamin A Deficiency

Vitamin A deficiency can cause sight issues. "A lack of vitamin A causes the cornea to become dry and that makes the eyes cloudy and can lead to vision loss," Dr. Graham says. "It can also damage your retina."

Vitamin B12 Deficiency

Are you dealing with constant fatigue and memory issues? You may have a B12 deficiency. “Signs of a B12 shortfall include fatigue from anemia; numbness in hands, legs, and feet; or trouble with balance and walking,” says Harvard Health. “Memory can also suffer. Vitamin B12 is readily found in fish, chicken, milk, and yogurt. If you prefer plant-based options, try fortified non-dairy milks and cereals. Adults need 2.4 micrograms of B12 each day.”

Iron Deficiency

Iron deficiency is more likely to be common in women. “If you're low on iron, you may feel cold, tired, or short of breath,” says Harvard Health. “You may have headaches more frequently. Meat and seafood typically offer plenty of iron, and plant-based sources include beans, lentils, grains, spinach, and fortified cereals. Women over 50 need 8 milligrams (mg) of iron per day; younger women, 18 mg daily.”

Vitamin C Deficiency

Vitamin C deficiency can cause unexplained bruising. “Severe vitamin C deficiency can lead to a disease called scurvy, which causes anemia, bleeding gums, bruising and poor wound healing,” says the Mayo Clinic. “If you take vitamin C for its antioxidant properties, keep in mind that the supplement might not offer the same benefits as naturally occurring antioxidants in food. The recommended daily amount of vitamin C is 90 milligrams for adult men and 75 milligrams for adult women.”

Vitamin B7 Deficiency

A lack of vitamin B7, known as Biotin, can cause fatigue and hair and skin issues. “Deficiency may lead to neurological symptoms, including numbness, tingling, and muscle cramps,” says Narayana Health. Some individuals may experience cognitive issues, such as mental confusion or mild depression.”

Low Potassium

Symptoms of low potassium may include fatigue, muscle cramps, weakness, and constipation. “Abnormal heart rhythms (arrhythmias) are the most worrisome complication of very low potassium levels, particularly in people with underlying heart disease,” says the Mayo Clinic. “Treatment of low potassium is directed at the underlying cause and may include potassium supplements. Don't start taking potassium supplements without talking to your doctor first.” And if you enjoyed this article, don't miss these 20 Superfoods for People Over 50.

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.

Do you have a nutritional deficiency? According to research, nutritional deficiencies may cause developmental failure, loss of various body functions, and several other diseases, such as diabetes, vision loss, immunity loss, and cancer. What are the major causes of nutritional deficiencies? Insufficient intake of food, inability to absorb nutrients, and consumption of diets that lack some of the essential nutrients. So, how do you know if your body needs more nutrients? Janine Bowring, ND, is a naturopathic doctor, best-selling author, researcher, and formulator. In a new video, she answers the burning question. “Here are six signs your body needs more nutrients,” she says in the YouTube clip.


Muscle Spasms

https://youtube.com/shorts/-H165m1iV-s?si=_VLtZThW_tmyqSGJ

The first symptom that can signal a nutritional deficiency? “Number one, muscle spasms,” Dr. Bowring says, noting the symptom is also referred to as “Charlie horses.” What does this signal? “A magnesium deficiency,” she says, noting that you can take a magnesium supplement.

Teeth Grinding

Do you wake up in the morning with a sore jaw? “Number two, if you grind your teeth at night, that can be an indication of parasites,” she says. She adds that it could also be due to a probiotic deficiency. The solution? Amp up your probiotic intake. You can do this by eating a probiotic-rich food or taking a supplement.

Nutritional deficiencies can manifest in dermatological issues. “Number three, keratosis pilaris,” Dr. Bowring reveals. “Those bumps on the backs of the arms” may be a sign that you have a vitamin C and vitamin A deficiency. “You could have a low thyroid as well,” she says.

Hair Loss

Does it seem like your hair is shedding? Number four on Dr. Bowring’s list is hair loss. “This can be related to low iron, omega 3s, and low protein,” she says.

Numbness or Tingling

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

Sick woman with headache sitting under the blanket​Frequent InfectionsShutterstock

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."

Warning Sign 4 Sciatica and Back Pain

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.

Warning Sign 2 Electric Shock Sensations

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

Portrait Of Young Arab Man With Shoulder Pain Suffering Sport Injury During Training At Gym, Middle Eastern Male Athlete Having Trauma After Fitness Workout, Rubbing Painful Area, CloseupShutterstock

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.

The 1 Fix for Diabetic Nerve Pain

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

Los Angeles, California, United States - 02-01-2023: A view of several bottles of Nature Made B12 vitamins, on display at a local grocery store.Shutterstock

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.

Erin Oprea is showing off her tiny waist – and schooling her followers about the importance of protein. In a new social media post, trainer to country stars Carrie Underwood and Maren Morris, discusses how protein is so crucial to weight loss. “LADIES, sooooo many of you are lacking PROTEIN!!! I hear it daily from you guys. A lot of women are getting 30 to 50 grams per day, that’s TERRIBLE!!! It’s time today to start focusing and you’ll see/feel a world of difference in your body!!!” she wrote in the caption, revealing 9 signs that you are protein deficient.


1. Hungry Quickly After Eating

The first sign you aren’t getting enough protein is that you get hungry shortly after eating. “For most individuals who are trying to lean out, we want to make sure that your protein intake is high, because that will help with hunger and fullness,” Chris McMahon, a nutrition and fitness coach, explains to The Body Network.

2. Losing Muscles

If you notice your muscles are dwindling away, it might be because you aren’t getting enough protein, according to Erin. McMahon explains that protein is a fundamental building block for muscles and helps you preserve them. “And if you are lifting weights and you are training, it'll help you build muscle,” he says.

3. Thinning Hair

According to Erin, thinning hair is another sign you aren’t getting enough protein.

4. Always Sore

Are you always sore? Maybe you aren’t getting enough protein, per Erin. McMahon confirms that protein helps you “recover” from your workouts.

5. Anemia

Are you anemic? It could be because of your diet. “Anemia is a condition that develops when your blood produces a lower-than-normal amount of healthy red blood cells,” explains the NIH. One of the ways you can become anemic is through an iron deficiency, and protein can help with that.

6. Brittle Nails

Do your nails keep breaking? Erin mentions that it may be due to lack of protein – and UCLA Health agrees. Along with brittle hair, brittle nails are “often the first sign of deficiency,” they say.

8. Fatigue

If you feel tired, you might want to amp up protein, says Erin. UCLA Health also notes that trouble thinking “due to fluctuating blood sugar and protein’s effect on the brain’s neurotransmitters (which regulate mood)” and muscle weakness, “since amino acids are essential for building muscle mass,” are signs of protein deficiency.

9. Getting Sick Often

If you are getting sick a lot, take your protein situation under consideration, says Erin. UCLA Health adds that protein helps boost the immune system.

"Right now only Wegovy is approved for chronic weight management. Ozempic is supposed to be used by type 2 diabetics only," explains Chef Zigga, who then revealed that "GLP-1 is in a lot of food." Read on to discover which kitchen staples might help you feel fuller longer without needing a prescription.

1. Omega-3 Rich Salmon

Salmon stands out as a top natural source of GLP-1-stimulating nutrients. "GLP-1 is basically food that have a lot of fatty acids, so omega-3s," Chef Zigga explains while presenting a salmon dish during the segment. This fatty fish provides high-quality protein along with those essential omega-3s that can help regulate appetite and slow digestion. Chef Zigga specifically highlights salmon when discussing foods with "more fats, more omega-3s" that support the body's natural GLP-1 production.

2. Creamy Avocados

Avocados earn their place on this list thanks to their healthy fat content that supports natural GLP-1 production. Chef Zigga specifically mentions avocados when discussing foods rich in omega-3 fatty acids, noting, "If you're looking for something with more fats, more omega-3s, then you have salmon, then you have stuff like avocado." These versatile fruits provide the satisfying fats that help trigger hormones that regulate appetite and digestion, similar to how Ozempic works in the body.

3. Surprising Brussels Sprouts

Don't underestimate these little green powerhouses! "Brussels sprouts actually have more omega-3s than avocado does," Chef Zigga reveals during the segment, highlighting their impressive nutritional profile. These cruciferous vegetables not only contain unexpected levels of omega-3s but are also packed with fiber that helps slow digestion and prolong feelings of fullness. Chef Zigga specifically included brussels sprouts under the salmon in their demonstration, creating a GLP-1 boosting power plate.

4. Fiber-Rich Asparagus

Asparagus makes the list thanks to its impressive fermented fiber content that supports digestion and satiety. Chef Zigga specifically mentions that "fermented fibers, that's what helps you stay fuller longer," highlighting vegetables like asparagus in this category. This spring vegetable works in your digestive system much like GLP-1 medications do - slowing food movement and helping you feel satisfied longer after meals.

5. Lean Bison

Bison offers a red meat alternative that supports natural GLP-1 production without excess fat. "Bison is a lean meat," Chef Zigga explains while presenting bison meatballs. During the segment, they specifically recommend that "if you're trying to lose weight, you want to stay with 90-10 ground beef, you want to stay with lean meats like bison." This protein-packed option helps trigger satiety hormones naturally while providing satisfying flavor with less fat than traditional beef.

6. White Fish Varieties

White fish varieties deserve space on your plate when looking for natural GLP-1 supporters. Chef Zigga specifically mentions "white fish" among the foods rich in "high fat content, high omega-3s, fermented fibers." These lighter fish options provide lean protein that helps trigger satiety signals while offering healthy fats that support hormone production. They're versatile enough to prepare in countless ways, making them an easy addition to your meal rotation.

7. Lean Chicken

Everyday chicken earns its spot on this list as a practical protein source that supports natural GLP-1 function. Chef Zigga specifically lists chicken among recommended "lean meats" that support weight management, alongside bison and venison. The lean protein in chicken helps trigger satiety hormones naturally, helping you feel full longer after meals - similar to the effects of GLP-1 medications like Ozempic and Wegovy.

"If you're looking for something, even shrimp, honestly," Chef Zigga mentions when discussing lean protein options during the segment. This versatile seafood provides high-quality protein with minimal fat, helping to trigger those important satiety signals naturally. Shrimp cooks quickly and can be incorporated into countless dishes for an easy GLP-1-supporting meal.

9. Filling Oats

Start your day with oats to naturally support your body's GLP-1 system. "Oats are a fermented fiber. They help keep you fuller longer," Chef Zigga explains while demonstrating how to make overnight oats. This breakfast staple slows digestion and provides steady energy, helping you avoid hunger pangs between meals. Chef Zigga specifically highlighted overnight oats as an effective way to incorporate this GLP-1-supporting grain into your diet.

10. Protein-Packed Greek Yogurt

Greek yogurt earns its place on this list as a versatile, protein-rich food that supports satiety. Chef Zigga includes it as a key component in their overnight oats recipe, recommending "a half cup of Greek yogurt" as one of the "main components" in this GLP-1-supporting breakfast. The combination of protein and probiotics in Greek yogurt supports digestive health while helping to trigger satiety hormones naturally.

11. Trilogy of Seeds: Flax, Hemp & Chia

Small but mighty, this seed trio packs a powerful GLP-1-supporting punch. Chef Zigga showcases what they call "Trilogy" - a combination of flaxseeds, hemp, and chia seeds. "Flaxseeds for every tablespoon is 1.6 grams of omega fatty acids, but then it's very high in fiber. Hemp is for every tablespoon is a thousand milligrams of exactly a fiber also, and then as well as the chia seeds," they explain. These tiny powerhouses deliver concentrated doses of the same omega-3s and fiber that help GLP-1 medications work.

12. Tropical Papaya

Complete your GLP-1-boosting diet with papaya, a fruit that directly supports hormone production. "Papaya also activates your GLP-1 secretions as well," Chef Zigga specifically notes during the segment. This tropical fruit not only adds natural sweetness to meals but contains enzymes that support digestion and help regulate appetite naturally. Chef Zigga demonstrates adding papaya to overnight oats, creating a breakfast that mimics the effects of weight loss medications.

While medications like Wegovy and Ozempic have proven effective for weight management, Chef Zigga demonstrates that many everyday foods naturally contain or stimulate the same GLP-1 hormones that make these drugs work. As they explain, these foods "help you stay fuller longer" and "activate your GLP-1 secretions" - the same mechanisms behind prescription weight loss medications. By incorporating omega-3 rich fish, lean proteins, fiber-filled vegetables, and strategic seeds into your diet, you may be able to naturally boost your body's GLP-1 production. As always, consult with your healthcare provider before making significant changes to your diet or stopping any prescribed medications.

Have you been struggling to lose weight most of your life? Even though it may seem impossible, especially if you have over 100 pounds to lose, seeking inspiration from other people’s stories and learning what worked for them can be the push you need. Lindsey Subrinsky, owner of Shot Bar MedSpa in Chicago, Illinois, struggled with her weight for most of her life – until she made some life-changing choices that helped her lose 140 pounds and keep it off. She recently told her story to Body Network, and it’s very inspiring.

Her Mom Took Her to Weight Watchers When She Was 10

Lindsey’s mother took her to her first Weight Watchers meeting in 1993 when she was just 10 years old. “It was a group just for kids, and the rooms were always full of parents who feared their child would be fat. That was my first forced experience by my mom to lose weight,” she recalls. “I knew I was successful at losing the 10 pounds I was asked to lose when my mom gave me the approval of two thighs that no longer touched. I had no idea how this was going to shape my life, and neither did my mom who believed she was doing the right thing after struggling with her weight in her youth.”

She Struggled Throughout Her Youth

The next few years would be brutal. “In the 7th grade, I was forced once again to try a liquid diet program by an MD who thought that was healthy,” she says. For days on end, she would only drink protein shakes while her little brother ate mac and cheese and Doritos. “One year, I got two clementines for my birthday with candles in the middle instead of cake. I know now, as an adult, that my mom believed she was doing the right thing for me. It's taken a lot of therapy and self-healing to forgive, but I know she was well-intentioned.

She Hit Bottom at 272 Pounds

Fast forward to the year 2018. “I had lost an immense amount of pounds over the years and would gain them right back, 50 off, 75 on. Fad diets, starvation diets, phentermine diets, you name it, I tried it. What is the feeling beyond hopeless? Whatever that word is could have described how I felt when I stepped on the scale to see 272 pounds one morning after the inability to roll over in bed one evening without losing my breath. That morning was the last time I’d ever see that number,” she says.

She Lost 100 Pounds in Less Than 10 Months with a Science-Based Approach

She took a science-based approach to weight loss. “I am a medical professional who believes in science and data to influence decisions. I took my knowledge and decided to make some changes that launched me to a 100lb weight loss in less than 10 months. I needed graphs and to notate linear changes.”

She Also Used a Smart Scale, Food Tracking Apps, and Activity Tracker

“I bought a smart scale, downloaded a food tracking app (that I still use to this day and request my weight loss patients do the same), got an Apple Watch to track health data, and a food scale,” she tells us. “It became a mission of knowledge. I began to weigh all of my food and stay within a certain macronutrient range that I learned how to calculate. I liked weighing everything because I believe knowledge is power. It took the guess and check out of the equation.”

She Followed a Low-Carb Diet Then Keto-Style

She started with a primarily lower-carb diet and transitioned to a keto-style diet later on “so I had room for change as the pounds began to fall off,” she says. “This journey was all about changing my relationship with food, and learning to say no to myself. It became a game and I was going to win this time.”

Jump to 2024. “I have kept off a 140-lb weight loss since 2019,” she says, revealing that she lost her last 15 lbs with a GLP-1 in 2022. “My habits have remained the same.

She Weighs Herself Daily

“I know some weight loss ‘experts’ will balk at what I am about to say, but I weigh myself daily. It keeps me self-aware, and I believe that knowing these numbers dictates my behavior. I have rules about what the numbers mean throughout the week and around my cycle, and I have learned that one bad night of eating will not completely derail my success. It’s just the opposite.”

She Also Takes a Day Off Every Few Weeks

This leads to another piece of advice she has for anyone trying to lose and/or maintain. “Take a day off every couple of weeks,” she suggests. “Your body is a machine that gets used to whatever you do every day. Have a day that, if you are craving something, enjoy it without feeling guilty. We are humans who also have to ‘live.” Occasionally, one ice cream cone and a couple of pieces of pizza are okay.”

She Didn’t Exercise During Most of Her Weight Loss Journey

She gets asked a lot about her fitness routine. “Truth is, I did not exercise for a single moment during 2018-2019,” she confesses. “I bought a Peloton early in 2020, right before the pandemic, and started a fitness routine then. My reasoning for that was I was always a perfectionist who crashed and burned and tried to do too much and change too much at one time.”

“This part of my story was about learning to say no to myself. It is still something that I work on every single day, as food was my reward and emotional outlet. Not using food for comfort has become easier, but it is still often my first instinct. I have just trained my mental muscle to know that I am stronger than my thoughts and I hate food remorse. I love being healthy, fitting into anything I want to wear, and knowing I can win against my biggest demon, my fat self who is still ever-so-present, I’ve just learned other ways to ‘feed’ her,” she concludes.
