As a RD, I have gotten so many questions about the fad diet du jour: the "Keto" or "Ketogenic" diet. I finally decided to just write down the research in a reader-friendly version. Additional video on the history and use of the ketogenic diet at the bottom of this post. Here you go-
The ketogenic (or “keto”) diet is just another fad diet.
The Keto diet is an amped-up Atkin’s diet (that we all know now was/is terrible for your cardiovascular system, and not a sustainable way to keep weight off) where the majority of what you eat comes from fat, and carbohydrates are extremely limited (In contrast, a healthy diet should be a much more balanced macronutrient distribution of 20-35% protein, 45-65% carbohydrate, and only 10-35% fat). This skewed macronutrient distribution is actually very dangerous for the human body for several reasons -
#1, We use carbohydrate as fuel for our brain. Glucose is needed for cognitive function, and many people on the Ketogenic diet experience brain fog and difficulty focusing. Ketone bodies (specifically: beta-hydroxybutyrate (built up in blood serum), acetoacetate (found in urine), and acetone (responsible for that bad breath)), which are created when carbohydrates are not present, are not as effective (or healthy) for our brain. This may also cause metabolic acidosis which is characterized by a reduced pCO2 and/or lower pH (we need to stay in balance!).
#2, On a ketogenic diet, your intake of fruits and vegetables is extremely limited (if eaten at all) and we all know how important the fiber, vitamins, minerals, and other compounds in fruits/veggies are. On that note…
#3, The keto diet is extremely low in fiber! Fiber is not only protective against many gastrointestinal cancers, it is also a big factor in fullness and weight loss. Furthermore, constipation is very common on low-fiber diets like the Keto diet.
#4, Ketosis/ketoacidosis is what is happening in the body/brain on a chemical level – this is the body making fat into something the brain can use when carbohydrates are not available. It's a lot of work for the the body to produce, not as efficient as carbohydrate, and can be incredibly dangerous for diabetics. Additionally, we have some cells with few-to-no mitochondria. These cells are carbohydrate-dependant and must be fueled by glucose. These cells include certain cells with no mitochondria in our blood (erythrocytes), eyes (cornea, lens, and retina); cells with few mitochondria include renal medulla, testis, and leukocytes. (https://link.springer.com/article/10.1007/s11883-003-0038-6)
#5, “Keto breath.” Halitosis (bad breath) from (acetone) ketone bodies makes for an acetone-like smell on your breath that no amount of brushing/mouthwash can fix. Medical professionals look for (smell for?) this in malnourished patients.
#6, High blood lipids/cholesterol/blood pressure. It’s a high fat diet- you didn’t see this coming? The body can only break nutrients down at a certain rate, and high levels of fat in the diet may lead to high levels of blood lipids are responsible for blockages (atherosclerosis), and other cardiovascular complications up to death. While you can reverse the numbers, the plaque buildup in arteries is almost impossible to reverse. Not worth it! (note: some people do see lowered blood lipid profiles on this diet).
#7, Following this diet is often a form of disordered eating or may lead to an eating disorder (just as with any restrictive diet). Cutting out whole food groups is not healthy. We need all 3 macronutrients in appropriate proportions (majority coming from carbohydrates) to have a healthy body. Our body needs a variety of foods for best health. The reason this diet “works” for weight loss is that it restricts the types of foods that people tend to over-do-it-on like chips, candy, pastries, etc. Any diet that cuts out your favorite foods will cause weight loss, but at what cost (physically and mentally?)
#8, Not all fats are created equal. Most people starting a Keto diet are not differentiating between saturated (solid at room temp, and not something we want in large quantities) and unsaturated fats (liquid at room temp, and “healthier”). Getting this wrong also increases complications from the diet. Additionally, many people who followed a diet high in medium-chain-triglycerides (MCT) experienced undesirable digestive issues.
#9, It may mess with your thyroid and other hormones – lowering your metabolism (isn’t the point of this diet weight loss? That’s counter-intuitive…), energy, and fertility. Every time we lower our metabolism through dieting it lowers the “set-point” of our metabolism, making it harder and harder to lose weight. This is an adaptive response for mammals in famine, but not what the average person wants nowadays.
Who it the Keto diet appropriate for?
The only population that the ketogenic diet is scientifically proven to be beneficial (and safe) for is a select group of people with epilepsy (seizure disorders). This is the position of the Academy of Nutrition and Dietetics.
The Keto diet especially sucks for athletes (and people working out to lose weight)
Since our preferred fuel source is glucose (carbohydrate) from either blood glucose or glycogen (fancy term for carbohydrate stores in the liver and muscle cells), running exclusively on fat slows athletic performance as the body works much harder to break down fat (dietary and adipose storage).
Additionally, the lower protein intake and change in hormones in the body with a keto diet lower the ability to build and maintain muscle mass. If “mirror muscles” like biceps are not motivating enough to keep you off it- remember that our organs like the heart are also muscle tissue that would be broken down by this diet, causing organ damage or failure.
It’ll get you, mentally and emotionally
Ketogenic diets cause headaches, brain fog, and often irritability and obsession with food. This type of diet will very likely make you think about food an unnecessarily large amount of time, and make it difficult to be social (not being able to eat at the same places as your friends; oh, and that bad breath!).
You may feel more depressed (especially if you are already prone to depression and/or taking antidepressants) as serotonin (the “happy” neurochemical) is produced from carbohydrates. If you take an SSRI know that this class of medications work directly on serotonin that is present, and the diet requires a minimum about of carbohydrate (as we learned from the works of Ancel Keys in his starvation study) to allow the SSRI medication to work.
So, what’s the verdict?
In case you didn’t get it from the above – the Keto diet sucks. Not only is it a fad-diet (aka – not suitable for long-term weight loss/lifestyle), it can be very dangerous.
If you need help figuring out what to eat, contact a Registered Dietitian. In the meantime, if you do need some structure, balanced eating like the Mediterranean diet or DASH diet is a better way to go.

I am thrilled to have this guest post about vegan nutrition!
Many of my eating disorder clients have adopted a vegan diet, for better or worse, and are not meeting their nutritional needs. Vegan and vegetarian diets are very healthy when done correctly, but if the whole purpose is to cut more things out in the name of restriction, then malnutrition is almost certain.
If you are vegan, or contemplating starting a vegan or vegetarian diet, read-on to learn about plant-based sources of certain nutrients that are often hard to get when animals are off the table.
The Vegan Diet - A Guide to Nutritional Needs
By: Emily Baird
Emily is a 1st year nutrition student at Cal Poly who plans to become a registered dietitian. She has been vegan for 2 years, and plans to incorporate that into her career.
Every year more and more people are making the transition to a vegan diet, and for good reason! The vegan diet can have so many health benefits for our bodies including disease prevention, weight management, and protection against cancers. But with being vegan, also comes the common questions about: “How do vegans get enough protein?” “How are they getting any B12 in their diet?” “How to vegans get calcium if they don’t drink cow’s milk?”. And although these are valid questions, a well-balanced diet full of fruits, vegetables, beans, legumes, and carbohydrates is all a vegan needs to fulfill their nutritional requirements.
Iron is an important component of the red blood cells that carry oxygen from the lungs to the rest of the body, as hemoglobin. Think of it like the engine to a car; the engine provides the car with the power it needs to make it move. Similarly iron allows hemoglobin to have the needed strength to get oxygen where it needs to go. Without it, the body cannot make hemoglobin, which means organs and tissues won’t get the oxygen they need.
There are two types of iron - heme and non-heme. “Non-heme” iron is found only in plants foods and is harder for the body to absorb than “heme” iron which is only found in meat products, so we need to eat more plant-based iron to truly get the same amount as if we were eating meat.
Many plant foods are naturally high in iron, but there are also many packaged foods that are now being fortified with iron. The recommended daily allowance (RDA) is between 8 - 18 mg (depending on age and gender, up to 27 mg during pregnancy). Be sure to include a source of vitamin C with your iron for better absorption.
VEGAN SOURCES OF IRON
1 cup soybeans: 8.8 mg
2 tbsp flax seeds: 4.1 mg
½ cup cooked lentils: 3.3 mg
½ cup fortified total whole grain cereals: 8 mg
(For a complete list click here)
Calcium is responsible for building and maintaining strong bones and teeth. When the body isn’t supplied with sufficient amounts, it increases the risk of developing disorders like - osteoporosis, hypercalcemia, kidney disease, and even alzheimer's. Calcium can be included either by nutrient dense foods or by incorporating calcium fortified foods. Most breakfast cereals, milks, breads, and juices contain added calcium, but be sure to read the nutrition label to be sure. The RDA is around 1000 - 1300 mg. Vitamin D intake is essential to adequate calcium absorption.
VEGAN SOURCES OF CALCIUM
100 g calcium set tofu: 350 mg
¾ cup calcium fortified plant milk: 240 mg
⅓ cup cooked kale: 110 mg
¼ cup dried figs: 95 mg
(For a complete list click here)
Zinc is essential for the body’s immune system to function properly. It also works in cell division, cell growth, the breakdown of carbohydrates, and wound healing. Although it is so important for our bodies, not much is actually needed; the RDA for zinc is 11 mg for men and 8 mg for women. Even though plant sources of zinc are not absorbed as easily as animal sources, vegans were shown to only have a slightly lower amount of zinc.
VEGAN SOURCES OF ZINC
Tofurky italian sausage: 9 mg
½ cup hummus: 2.3 mg
1 tbsp nutritional yeast: 2 mg
¼ cup roasted pumpkin seeds: 2.3 mg
(Click here for a complete list)
Your body must have vitamin D in order to properly absorb calcium in the body. Vitamin D is not typically a problem for vegans during the summer months, but those living in colder climate may be at risk of developing a vitamin D deficiency. The RDA is 600 - 800 IU. Just about 10 to 20 minutes (depending on skin tone) in the sun per day will provide the body with sufficient levels. But those living closer to the northern hemisphere, may need to include more vitamin D rich foods in their diet.
VEGAN SOURCES OF VITAMIN D
1 cup portabella mushrooms: 634 IU
1 serving instant oatmeal: 180 IU
1 cup fortified soymilk: 120 IU
1 cup fortified orange juice: 100 IU
(Click here for a complete list)
SHOULD I BE INCLUDING SUPPLEMENTS?
Eating a healthy variety of plants and grains will ensure that the body gets sufficient levels of nutrients. The exception to that is vitamin B12. Vitamin B12 is not as easily accessible through plant based foods, so it can be important to include a supplement in your diet. If you are overwhelmed by what kind of B12 supplement to choose, check out this article. Nutritional yeast is an example of a vegan food that does naturally contain B12. It is usually used as a cheese replacement or topping, and can supply 2.4 mcg per 3 tbsp (which is the RDA).
A well-balanced, plant based diet will supply the body with all the nutrients that it needs to thrive. There are many people who question the vegan diet and believe that vegans are lacking essential nutrients, but with the right knowledge of nutritional needs, a vegan diet can be very beneficial.

Don't just take my word for it, a wonderful article about this course was written by the creator of OnStage Blog. Here it is for more info:
Something I talk about frequently with my clients is the concept of "normal eating." We are all born with the innate ability to tell when we are hungry and when we are full. Our brain and gastrointestinal sensors help us to desire a variety of foods that will nourish our body... but somewhere along the way society can confuse our senses of what eating is supposed to be like. So....
In the dietetics and eating disorder industries, a quote about normal eating has become the gold-standard. Leading child eating-behavior-expert, Ellyn Satter's quote is as follows:
What is Normal Eating?
By: Ellyn Satter, MS, RDN, MSSW
Normal eating is going to the table hungry and eating until you are satisfied. It is being able to choose food you like and eat it and truly get enough of it -not just stop eating because you think you should. Normal eating is being able to give some thought to your food selection so you get nutritious food, but not being so wary and restrictive that you miss out on enjoyable food. Normal eating is giving yourself permission to eat sometimes because you are happy, sad or bored, or just because it feels good. Normal eating is mostly three meals a day, or four or five, or it can be choosing to munch along the way. It is leaving some cookies on the plate because you know you can have some again tomorrow, or it is eating more now because they taste so wonderful. Normal eating is overeating at times, feeling stuffed and uncomfortable. And it can be undereating at times and wishing you had more. Normal eating is trusting your body to make up for your mistakes in eating. Normal eating takes up some of your time and attention, but keeps its place as only one important area of your life.
In short, normal eating is flexible. It varies in response to your hunger, your schedule, your proximity to food and your feelings.

A common myth I hear from people is that we need to "cut out carbs."
No, we need the majority of our daily calories from carbohydrates.
Yes, different conditions require different amounts, but we still need quite a bit.
If we are eating the correct amount of calories for our needs our composition should be broken-down roughly into the percentages shown below.
I created a quick cheat-sheet for you about how much Carbohydrate/Fat/Protein we need.

You have probably read other articles on tips for eating around the holidays, but in my experience, repetition is never a bad thing when it comes to making a new habit. In fact, maybe there will be things on this list that you have NOT heard yet...you never know what is going to be of great use to you...so read on, and apply as needed. :)
1) Drink water! Hydration is often forgotten with coffee, hot cocoa, and alcohol fighting for top contenders in your liquid category at this time of year. Thirst is readily mistaken for hunger when tasty options are before you. So remember to drinkyour 8 glasses of water (or tea) every day. Try drinking a pint before you leave the house, carrying a water bottle with you, alternating alcohol with water, and eating water-rich foods such as apples, cucumber, grapes, and salad greens.
2) Eat what you really want. Don't keep munching on things you "should" eat, and end up over eating because you are not fulfilling your cravings. This is probably the only time of year for your aunt's famous sugar cookies, Grandma's pie and stuffing, and other family goodies; enjoy them, savor them. You will probably end up eating less over all if you don't deny what you want.
3) Fit in exercise every day. Whether it is a dance DVD in your living room, a run in the brisk morning air, a gentle walk with the family (or the dog), or a class/weights at the gym. Be like Nike and, "Just Do It." Exercise will keep you in a better mood - and that is helpful to everyone around you as well!
4) Don't let ALL your meals be splurges. Big Christmas dinner? Eat healthy breakfast and lunch that day so you are not overdoing it (do NOT skip meals!!!). It is easy to fall into the habit of splurging at every meal during this season, whether that is what is in the house, or you feel so stressed you "deserve it," remember there are celebrations all year round, and you need to focus if you do not want to become 'round.' Do eat what you love, but you don't have to sample that so-so dish, just because Aunt Sally made it.
5) Send away the leftovers. Hosting a get-together? At the end of the meal, pack up leftovers into small containers and send most of it away with guests. If there is less in your fridge, there is less for you to pick at later.

People intrinsically want to believe and have hope in something. When “big-pharma” and doctors are not making patients feel significant and understood, people will go searching for healing elsewhere, this is where dietary supplements (DS) come in. Most DS work under the realm of “placebo effects,” unless they are being used to treat a nutritional deficiency.
The definition of “placebo effect” is, “improvement in the condition of a patient that occurs in response to treatment but cannot be considered due to the specific treatment used(1).” This phenomenon has been identified in several studies. One of which was a study of patients with irritable bowel syndrome (IBS) which “treated” patients with either “open-label placebo (non-deceptive and non-concealed administration)” or no treatment. Even knowing that the pill they were given was a placebo made of an inert substance, the sufferers found significant relief over those receiving no treatment. The conclusion was that “Placebos administered without deception may be an effective treatment for IBS (2).”
Doctors have long-known the benefits of placebo effects in patients and will utilize this in treatment. While the “placebo” thinking may help people heal, “no-cebo” thinking can render even an active drug useless. This phenomenon is summed up well in Henry Ford’s famous quote: “whether you think you can or cannot, you are correct.” It may be that doctors owe it to their patients to boost healing by any means possible, including treatment by placebos for more effectiveness (3). Nonetheless, the American Medical Association stated in 2006, that it is unethical for doctors to give patients undisclosed placebo treatment/medications (4). If doctors are ethically not allowed to give undisclosed placebos, then suggesting a DS labeled, “This product is not intended to diagnose, treat, cure, or prevent any disease” might be their way around this ethical dilemma.
Psychological effects of placebos
The placebo effect often is used, consciously or not, in the context of classical conditioning. Discovered by Ivan Pavlov, classical conditioning takes a neutral stimulus (which should cause no response - the “placebo”) and, through learned response, makes it a conditioned stimulus to elicit a conditioned response (5). An example of this in the medical setting would be giving a patient a pain medication that actually works to reduce pain every day for five days, then giving a sugar pill that looks the same on the sixth day and eliciting the same pain-reducing response.
The conscious expectations by a patient of a treatment to work may cause an inert substance to have a desired effect on the patient. These expectations can be elevated by how the health care professional (HCP) interacts with the patient. The study of medicine “generally does not pay adequate attention to psychological and social variables (6),” which are determined by the relationship of the HCP and patient. This may interfere with drug study controls. If the person in the placebo group of the study is getting attention and believes the treatment will work, then they may exhibit signs of the placebo working that may make the active treatment not have a significant desirable outcome over the placebo.
Yet, how can an inert substance elicit a similar response to an active treatment? A large part of this stems from the psychological variants at play. Much of the patient’s outcome may be determined by the HCP’s confidence in a treatment's ability to work, empathy, active listening, and care setting. “[it is] suggested that the success of the many forms of psychotherapy [are] due to a placebo effect rather than the distinctive features claimed by the different therapists (6).” Hope that it will work, and follow-through on actually seeking treatment, are other reasons that patients have better outcomes with either the active treatment or the placebo (7). DS are often prescribed either by licensed HCPs (like doctors) or “alternative healers” (like acupuncturists). The diplomas on the wall, or the attention given by the healer can contribute to the patient “feeling” the DS responding to treatment. Additionally, since chronic conditions often ebb and flow with severity, the patient is likely to look for treatment when symptoms are about to naturally decrease, leading to the belief that the DS “healed” them (8).
Physiological effects of placebos
Placebo effects are not “all in the head” as once thought. They can make actual physical changes in the body, under the right circumstances. A test group for an antidepressant medication versus a placebo showed interesting brain activity in the results. By viewing brain activity with fMRI studies, placebo responses increased activity in the prefrontal cortex of the brain, while the medication suppressed this activity. Both groups exhibited less perceived depression, though on different timelines (the drug working weeks faster than the placebo). To this finding, researchers said, “administration of an inert pill appears to be an active treatment rather than a no-treatment comparison as previously thought. [however, the] placebo response is not equivalent to an active drug response, since the two groups' brain physiology was altered differently (7).”
Even people with Parkinson’s disease can potentially have real physiological benefit from placebo “treatment.” The effect of the placebo increasing dopamine in the brain, modifying the neuron that is promoting the abnormal activity that causes the tremors (9). People in this study physically had reduced shaking while taking the placebo, showing that there is true physical effects in some placebo “treatments”.
Studies should have tighter placebo controls
The Food and Drug Administration requires new drugs to significantly outperform the placebo control before going to market (3). Placebo controlled, double blind trials have been the gold standard of research (8). However, most research studies for medical treatment (whether drug, DS, surgery, or other) could be better controlled for placebo response. This could be met with a few tweaks to methods of “treatment.”
Dr. John Farrar, a neurologist and epidemiologist, provides some insight into what can strengthen study design to control for placebo effects (3):
