Josh Axe, a doctor of natural medicine and clinical nutritionist, estimates that about 25% of people who try a ketogenic diet experience these symptoms, with fatigue being the most common. “That happens because your body runs out of sugar to burn for energy, and it has to start using fat,” he says. “That transition alone is enough to make your body feel tired for a few days.”
You’ll want to add a pop of blue to your meals with this berry delicious fruit. “Research has linked eating a diet rich in fruits and non-starchy vegetables with weight loss, but I really like blueberries because they're packed with antioxidants and are available all year round in the frozen aisle,” says Rizzo. Add to yogurt, oatmeal, and salads, or use for sweetness in smoothies, sauces, and dressings.

A 2009 review found that existing limited evidence suggested that encouraging water consumption and substituting energy-free beverages for energy-containing beverages (i.e., reducing caloric intake) may facilitate weight management. A 2009 article found that drinking 500 ml of water prior to meals for a 12-week period resulted in increased long-term weight reduction. (References given in main article.)
Nope — and it’s not the diet’s only name. Some know it by the Navy diet, the Army diet, or even the ice cream diet, since the three day menu allots for at least a few bites of vanilla ice cream each evening. Personally, we like to think that it’s called the military diet because it takes military-level self-control to stick to the restrictive meal plan.

The Military Diet is a very calorie-restricted 3 day diet that's based on the principles of consuming the right combination of metabolism-boosting foods. The diet also incorporates the idea of intermittent fasting with 3 days of very restricted eating followed by 4 days of a more moderate approach. While the diet itself is pretty straight forward, it's not for the faint of heart. This diet may be exceedingly difficult to stick with because it must be followed exactingly.

Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later, a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
Here are a few of the most common side effects that I come across when people first start keto. Frequently the issues relate to dehydration or lack of micronutrients (vitamins) in the body. Make sure that you’re drinking enough water (close to a gallon a day) and eating foods with good sources of micronutrients. To read more on micronutrients, click here >

Mindfulness techniques, especially those that cultivate self-awareness and compassion, may help people lose weight and keep it off. One key example involves noticing mindless eating, which happens when people eat without paying attention to their physical and emotional state. People sometimes eat to soothe anxiety, sadness, or other unpleasant emotions. Mindfulness practices teach people how to identify emotions rather than avoid them and to ride out cravings, which tend to come and go. (Locked) More »

Note: Are you a vegetarian or vegan and want to go on a ketogenic diet? It’s still possible! Just keep in mind that the dietary restrictions can sometimes be a little bit intense. Make sure to plan ahead and prepare to aid your success. To help out, we’ve published articles (with 7 day meal plans included) for both the vegetarian ketogenic diet and the vegan ketogenic diet.
The popular "flat belly diets"embrace much of the wisdom found in eating a Mediterranean diet, which helps everything from brain health to hearth health. The basic premise for both diets is eat foods rich in monosaturated fatty acids (MUFA) that may help reduce your belly fat storage. MUFA-rich foods include olive oil, nuts and seeds, avocodos, and fish. Eating yogurt regularly has also been found to be helpful in reducing belly fat.

According to the website, the Military Diet requires you eat specific foods for breakfast, lunch, and dinner over the course of three days. The meal plan is extremely calorie-restrictive: on the first day, for instance, you can only eat roughly 1078 calories. (For comparison, the average, moderately active male needs roughly 2400 to 2600 calories per day.)


By planning your meals and logging what you eat and drink, you will start memorizing how many calories are in your favorite meals and ingredients. Best of all you will learn your own eating habits and cravings, so over time you can better plan your meals to suit your cravings. After a couple weeks if you see you consistently have a 3:00 pm craving for carbs, you can head off that craving in advance with a skinny sandwich at lunch. Or, a sweet craving at 10:00 am can be managed with a sweet oatmeal breakfast.
"One of the hardest parts of losing weight is maintaining the lifestyle changes you’ve made. It’s difficult to stay motivated all the time, especially if you’ve slipped up along the way. But don’t let this affect your end goal. If you’re feeling particularly unmotivated, ask a friend to join you for your workout and then afterwards cook something healthy for dinner together."
The Military Diet’s focus on small quantities of high-fat food might leave you feeling hungry, too. “This is allowing a very little bit of rich food,” explains Gomer, noting that you’ll still feel hungry despite indulging in ice cream each night. “It makes me frustrated because I could give people six times the amount of food [for the same amount of calories],” says Gomer.

However, it's safe to say that no one really knows the origin of the military diet, Yurechko said, as it is certainly not approved by the military. But if you are still a tad bit curious about taking this diet out for a spin, we spoke to some experts on the subject to make sure you have all the ins-and-outs. Here are some takeaways to keep in mind.
For the first three days, the diet consists of three distinct meal plans. For the first day, breakfast consists of half a grapefruit, a slice of whole-wheat toast with 2 tablespoons of peanut butter, and a cup of caffeinated black tea or coffee. If you can't drink it black, it's recommended you sweeten it with a natural sugar substitute, like Stevia. For lunch, have half a cup of tuna (you can buy 3 oz or 5 oz cannes of cooked tuna, or prepare it yourself), one slice of whole-wheat toast, and a second cup of black coffee or tea. Dinner is the more filling meal, consisting of 3 oz of meat, one cup of green beans, half a banana, one small apple, and one cup of vanilla ice cream for dessert.
Appetite-suppressant drugs and other diet pills:"Wonder" products that permanently reduce weight do not exist. Products that promise immediate or effortless weight loss will not work in the long run. Appetite suppressants, which often contain a stimulant like caffeine or hoodia, are associated with side effects including nausea, nasal dryness, anxiety, agitation, dizziness, insomnia and elevated blood pressure. Alli reduces fat absorption; following the package directions will reduce risk of side effects, which may include oily diarrhea and anal discharge. With any product, side effects may be worse if you exceed the recommended dosage.
This drug is an injected variant of a satiety hormone called GLP-1. It slows down how quickly the stomach empties and tells the brain that you don’t need to eat yet – a great idea for losing weight. As a bonus this drug works fine while one is on the keto diet and it works even better with intermittent fasting – for a rapid weight loss with no hunger.
"If your diet consists of lots of sports drinks, sugar-sweetened drinks like fizzy pop and flavoured waters, or sugary foods like chocolate and cakes, it will make losing weight harder. While whole fruits and vegetables are undoubtedly good for you, they can also sometimes cause weight gain if you eat too much, as they have high levels of natural sugars in them. Low-fat food options might have high amounts of added sugar in there too, so make sure to check the food label.

In its 2016 report “Healthy Eating Guidelines & Weight Loss Advice,” the Public Health Collaboration, a U.K. nonprofit, evaluated evidence on low-carbohydrate, high-fat diets. (The Keto diet falls under the LCHF umbrella.) Among 53 randomized clinical trials comparing LCHF diets to calorie-counting, low-fat diets, a majority of studies showed greater weight loss for the Keto-type diets, along with more beneficial health outcomes. The collaboration recommends weight-loss guidelines that include a low-carbohydrate, high-fat diet of real (rather than processed) foods as an acceptable, effective and safe approach.

Gastrointestinal disorders are another common cause of unexplained weight loss – in fact they are the most common non-cancerous cause of idiopathic weight loss.[citation needed] Possible gastrointestinal etiologies of unexplained weight loss include: celiac disease, peptic ulcer disease, inflammatory bowel disease (crohn's disease and ulcerative colitis), pancreatitis, gastritis, diarrhea and many other GI conditions.
Slow down, we're not saying you have diabetes. But insulin resistance is "the beginning of your body not dealing well with sugar and carbohydrates," says Melina Jampolis, M.D., author of The Doctor On Demand Diet..  Basically, when you have insulin resistance, it means the body's cells have noticed an increase in sugar in the blood and ratchet up the amount of insulin to transport it to cells that process it for energy. A vicious cycle gets started, you create more insulin—too much of it, in fact—and your cells become resistant to it, leading to more free-floating sugar in your blood stream that eventually gets converted to fat and is usually stored in your belly. Unless you reverse the insulin resistance, your body will keep going round and round, and diabetes could develop. The key, says Jampolis, is to lose fat and build muscle. "Exercise, especially strength training, can improve your body's response to insulin even if you don't lose an ounce," Jampolis explains. Try lifting weights two to three times a week—these moves are great fat-blasters. 
The Johns Hopkins Hospital protocol for initiating the ketogenic diet has been widely adopted.[42] It involves a consultation with the patient and their caregivers and, later, a short hospital admission.[18] Because of the risk of complications during ketogenic diet initiation, most centres begin the diet under close medical supervision in the hospital.[9]
Instagram user @healthyhappydays_ was happy with her results, though. "I found it easy to stick to as it's only three days," she told us. "You know you're going to see results if you [are] 100% committed to it... If you're feeling bloated, especially after a big weekend or event, it's a good diet to do to get back to shape in a short space of time. That's the reason why I did it after being indulgent over [the holidays]." Because she typically sticks to a vegetarian or vegan diet, she substituted out two veggie sausages instead of the hot dogs and the meat.
Other down sides: There’s an initial period where your body is adjusting to its new carb-free existence, and many people experience symptoms like fatigue, brain fog and nausea for a few weeks. You also end up deficient in important micronutrients, like folate, calcium and potassium, which is why most ketogenic devotees recommend taking multivitamins. Personally, I recommend my clients follow a diet that in its ideal state provides all of the nutrients you need through real, whole foods.
Leanne found keto during her personal struggles with health and weight loss. It transformed her life, and she immediately set out on a path to help others find the same success. Leanne launched her online nutrition program “The Keto Beginning” in October 2014 and then “Fat Fueled” in November 2015, and on her website and YouTube channel (healthfulpursuit.com/video) she provides daily motivation tips, recipes, advice for getting started with keto, maintenance plans, and help overcoming hurdles.
You'd think it makes sense: if you have too much belly fat, do a lot of core work to make it go away. But Sylwia Wiesenberg, founder of Tonique Fitness, says it's counterproductive. "If you have extra belly fat, you'll never see the muscles you're working underneath," she explains. "Instead, focus on building a strong lower body—the largest muscle group, and therefore most calorie burning—which will help keep your metabolism humming long after." Then, when you are ready for abs work, do it standing up. A review of core training by the American College of Sports Medicine found that it's a more effective way to tone than traditional exercises that have you on the floor.
There are numerous benefits that come with being on keto: from weight loss and increased energy levels to therapeutic medical applications. Most anyone can safely benefit from eating a low-carb, high-fat diet. Below, you’ll find a short list of the benefits you can receive from a ketogenic diet. For a more comprehensive list, you can also read our in-depth article here >
Another difference between older and newer studies is that the type of patients treated with the ketogenic diet has changed over time. When first developed and used, the ketogenic diet was not a treatment of last resort; in contrast, the children in modern studies have already tried and failed a number of anticonvulsant drugs, so may be assumed to have more difficult-to-treat epilepsy. Early and modern studies also differ because the treatment protocol has changed. In older protocols, the diet was initiated with a prolonged fast, designed to lose 5–10% body weight, and heavily restricted the calorie intake. Concerns over child health and growth led to a relaxation of the diet's restrictions.[18] Fluid restriction was once a feature of the diet, but this led to increased risk of constipation and kidney stones, and is no longer considered beneficial.[3]
No shocker here: It turns out that the Military Diet isn’t quite the unique weight loss solution it’s made out to be. “This [diet concept] has been dressed up differently and brought out to dance before,” says Kimberly Gomer, R.D., director of nutrition at Pritikin Longevity Center. In other words, a restrictive three-day plan is nothing new in the health industry.

As with other types of extremely low-calorie diets, regaining the weight is almost guaranteed as soon as you stop the diet. “My own advice,” says Rothenberg: “Don't compromise for a big event! That often leads to weight gain and binge eating. If you want to change your diet, change your lifestyle. Studies actually show that ‘safe weight loss’ results in 1 to 2 lbs per week only,” citing recommendations from the Academy of Nutrition and Dietetics.” And that still is hard work,” she adds. Fad diets like the Military Diet put you at risk for regaining weight that is lost from muscle and water in particular.


As a self-described “nutrition nerd,” I couldn’t help but analyze the first three days of menus provided using my nutrient analysis software. You’ll see the daily totals at the bottom of each day, and while I can’t describe the intake as “good”, “ideal” or “healthy,” the data was slightly better than I expected. (Or perhaps, I really wasn’t sure what to expect from this very odd combination of foods!)

The diet doesn't offer balanced nutrition: some of the recommended foods are high in sodium, the reduced calorie intake is below the recommended allotment for both men and women, and you may not receive sufficient fiber, vitamins, and minerals during this three-day period. Prolonged application of the diet may weaken your organs and immunity as well as increase your risk of heart damage.


Yogurt is protein-packed and full of probiotics, which are good for gut health and may help your weight-loss efforts. Your gut health can impact your weight, and eating more fiber and probiotics helps keep your gut bacteria happy, which can be good for your metabolism (read more about your gut-weight connection). Go Greek for more protein; plus, research from Appetite found that consumption of Greek yogurt was associated with reduced appetite and increased satiety. Just keep an eye on added sugars in flavored yogurts, which only add calories. Instead, use fresh fruit to sweeten plain yogurt.
Exercise is an essential element of any weight loss program. Through exercise, you give your weight loss a boost by burning additional calories. However, since you’re on the restrictive 3-day diet, you should only do light exercise. Be sure that you listen to your body and if you ever feel light-headed while exercising- be sure to stop and rest. Each person’s body reacts differently to the diet, and for some, the calorie restriction can result in feeling a bit faint or dizzy.
Going gluten-free may be a popular trend, but unless you're actually gluten-intolerant or have celiac disease, plenty of reasons exist to continue eating whole grains. They're a tasty way to fill up on both soluble and insoluble fiber, which help you feel full for longer and keep bowel movements regular (oats, barley, and bulgur are especially high sources). Whole grains can also help prevent weight gain: in one study, women who ate whole grains like wheat germ and dark bread had a 49% lower risk of "major" weight gain over time.
"With all the different tips out there, it can be tricky to understand exactly which exercises work the best. HIIT is great for fat burning and will get your heart rate up, but I’d also recommend including strength (resistance) exercises too. Try lifting weights, using resistance bands or using the weight machines at the gym as these will increase your metabolism to help with weight loss, and increase your muscle strength. It’s important to mix-up your whole-body workouts so you don’t get bored."
The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
After about two to seven days of following this eating routine, you go into something called ketosis, or the state your body enters when it doesn't have enough carbs for your cells to use for energy. Then it starts making ketones, or organic compounds that your bod then uses in place of those missing carbs—and oh, it also burns fat for more energy, says Beth Warren, R.D., founder of Beth Warren Nutrition and author of Living A Real Life With Real Food.
Compared to other nut varieties, pine nuts tend to be on the pricier side, but adding them to your shopping cart could be a good investment for your health. Research suggests that the fatty acids in these little nuts could increase satiety hormones, helping you feel full. They're also packed with vitamin B1 and manganese, a mineral that helps your body metabolize carbohydrates and protein.

When I go to big meals at family-style restaurants or people’s homes, I keep my appetizer or salad plate for the entrée course. I load up on a lot of food during both courses but using the slightly smaller plate helps. I've also learned to fill my plates with mostly veggies. I will still gladly take a spoonful of mac and cheese, but I'm careful not to take more than that because I know that if it’s on the plate, it will end up in my mouth.
