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 >
Thank you for taking such a responsible viewpoint in this article. I think so many people and websites nowadays are talking about these diets, like the military diet, as a great way to drop weight quickly, but without discussion the repercussions or downsides to them. I don’t think a diet like this is healthy at all, and while it may be handy if you desperately need to drop a few pounds in a few days, I just don’t think it’s a healthy thing to do at all. I think it’s far better to maintain a healthy lifestyle and healthy diet 24/7/365 instead.
Because some cancer cells are inefficient in processing ketone bodies for energy, the ketogenic diet has also been suggested as a treatment for cancer.[58][59] A 2018 review looked at the evidence from preclinical and clinical studies of ketogenic diets in cancer therapy. The clinical studies in humans are typically very small, with some providing weak evidence for anti-tumour effect, particularly for glioblastoma, but in other cancers and studies, no anti-tumour effect was seen. Taken together, results from preclinical studies, albeit sometimes contradictory, tend to support an anti-tumor effect rather than a pro-tumor effect of the KD for most solid cancers.[60]
If your fitness goals include a flatter belly and stronger core, you're going to need a solid plan, expert guidance, and a little outside motivation. Our 30 Days to a Flat Belly plan has all three! This comprehensive workout plan will give you results you want without a pricey gym membership; you can do these workouts anywhere — and they're all 30 minutes or less.
Ultimately, you need to pick a healthy eating plan you can stick to, Stewart says. The benefit of a low-carb approach is that it simply involves learning better food choices—no calorie-counting is necessary. In general, a low-carb way of eating shifts your intake away from problem foods—those high in carbs and sugar and without much fiber, like bread, bagels and sodas—and toward high-fiber or high-protein choices, like vegetables, beans and healthy meats.

You’ll also notice that men seem to lose more weight than women. This is actually based on body composition. Sorry ladies, but men just naturally have a leg up on losing weight! Why? Because most men have more muscle tissue, so they are simply able to burn more calories than women. Muscle tissue burns more calories than fat, even when the body is at rest. If you’re a woman, you can gain the benefits of additional muscle that will help you burn more calories by focusing on strength training. That will help the body weight you do have burn more calories, essentially boosting your metabolism.

"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."
Keto breath, on the other hand, is less of a side-effect and more of a major (not harmful) inconvenience (your breath literally smells like nail polish remover). Basically, when your body breaks down all that extra fat on the keto diet, it produces ketones—one of which is the chemical acetone (yes, the same stuff that's in nail polish remover), Keatley previously told WomensHealthMag.com.

We reached out to two experts to see what they thought — and if the diet works. "It’s a low calorie diet that includes typical American foods," said Janis Jibrin, MS, RD, an adjunct professor of Nutrition at American University. "It’s nutritionally deficient, but not as crazy as some (i.e. juice fasts)." When it comes to the meal plan, she's not a fan. "It’s too low in many nutrients," she explains. Day 2 alone is "so low in fiber, iron, calcium and other nutrients, yet it manages to hit the daily sodium max. (Actually, most health authorities recommend 2,300 mg as a max, so this diet exceeds it.) Sure, the other four days offer more calories and nutrients, but even so, you’re still skimping."
Basically, the effect of exercise on our weight is vastly overrated. That’s why it’s only number 15 on this list. There are other things you need to take care of first. It’s not a good idea to eat bad food, drink sugar water (so-called “sports drinks”) or be on medications which force you to exercise for hours daily just to compensate. Metaphorically that’s like digging a hole, into which you put your ladder, on which you stand and paint the basement-level windows of your house.
While studies have found that eating nuts every single day can help you live longer than those who don't eat them at all, and the little guys help reduce that inflammation and insulin resistance we talked about above, Adam Rosante, personal trainer and author of The 30-Second Body, warns against going to town on them."A common diet tip you hear all the time is to snack on nuts when you're hungry," he says. "They're filling and packed with protein and fiber, and because they're so tiny it's easy to gobble down handful after handful. But you should enjoy them in moderation because the majority of their macronutrient profile is fat, and eating them mindlessly is an easy way to go overboard on your calories." Instead, he suggests snacking on a thumb-sized portion twice a day.

A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.3A study in the long-term effects of a ketogenic diet shows a significant reduction in cholesterol levels, body weight, and blood glucose.

Make sure that the diet has been studied extensively for safety — and discuss any changes with your physician or registered dietitian before beginning a new diet. (If you don’t have a dietitian, find one in your area at the Academy of Nutrition and Dietetics website.) And do a self-check to ensure the diet fits with your own values and preferences.
Carbohydrates are a touchy subject: while some blame them for all fat gain, it’s the type of carbs you eat that’s key. A 2011 study out of the University of Alabama found that a diet that slightly cut back on carbs, and which comprised mostly low-GI carbohydrates, lost more deep abdominal fat than those who ate a lower-fat diet. GI stands for glycemic index, a measure of how fast carbohydrates supply your body with energy: high-GI foods make you spike then crash, while low-GI foods provide a slow burn.

A 2015 study from Brown University found that you’re likely to have less belly fat if you have a high degree of “dispositional mindfulness” — where you’re naturally inclined to pay attention to your present thoughts and feelings. The researchers speculated that this kind of “everyday mindfulness” helps overcome the instinct to stock up on calories, which are not in short supply to use modern humans.
In terms of weight loss, you may be interested in trying the ketogenic diet because you’ve heard that it can make a big impact right away. And that’s true. “Ketogenic diets will cause you to lose weight within the first week,” says Mattinson. She explains that your body will first use up all of its glycogen stores (the storage form of carbohydrate). With depleted glycogen, you’ll drop water weight. While it can be motivating to see the number on the scale go down (often dramatically), do keep in mind that most of this is water loss initially.

Don’t let extra hours lounging in bed stand between you and a flatter belly. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
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.
“Thirst and hunger cues feel similar, so it’s important to stay hydrated, especially if you’re trying to lose weight,” explains Moon. Yes, plain water is important, but 20 percent of our daily water intake comes from foods, she says. “Watermelon is 92 percent water, plus it is bursting with vitamins A and C and anti-inflammatory nutrients like lycopene,” she explains.
When you're at the gym, don't head straight for the treadmills. Tim Rich, personal trainer and district fitness manager at Crunch Gyms in San Francisco says, "you lose steam when you save the weights for last, and that's where the magic happens." Weight-training burns approximately 30 to 50 more calories a day for every pound of muscle you gain, so "when you have more energy you'll be able to lift heavier weights, which helps you burn more fat everywhere, including your belly," he says. And researchers found that, while those who lifted heavy weights lost the same amount of weight as those who only did cardio, the only weight they lost was fat—the cardio queens lost muscle, and that's never good, especially as you get older. 
Rami co-founded Tasteaholics with Vicky at the start of 2015 to master the art of creating extremely delicious food while researching the truth behind nutrition, dieting and overall health. You can usually find him marketing, coding or coming up with the next crazy idea because he can’t sit still for too long. His favorite book is The 4-Hour Workweek and artist is Infected Mushroom.
For too long we’ve blamed dietary fat for weight gain and health problems. The truth is, a diet that’s high in natural, healthy fats can actually help your body burn fat! That’s the secret behind the ketogenic diet. As you get more of your calories from healthy fats and cut back on carbs, you’ll start burning fat, losing weight, and feeling strong and energetic—without feeling hungry or deprived.

Finally, lunch on day 3 is very light, consisting of only toast and an egg. You still get a small amount of protein from the egg as well as a smattering of vitamins and minerals such as Vitamin A, D, B-6 and B-12, and iron, all from the egg. You’ve now received an overview of the functions of all of these vitamins except for Vitamin D- which helps the body absorb calcium (1).

Kimchi is a spicy Korean condiment that's made with fermented cabbage and is a great source of vitamins A, B, and C. Because it's fermented (like sauerkraut), kimchi contains tons of those good probiotics that aid the body in digestion. A recent study in the Proceedings of the National Academy of Science found that maintaining healthy bacteria in your gut can improve gut lining, which in turn could help reduce fat mass and inflammation.


This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy. Research published in Clinical Cardiology suggests the ketogenic, or “keto,” diet can be an effective weight loss method, but to be successful, you must follow the plan consistently with no cheat days — otherwise, you’re just eating a high-fat diet that may be high in unhealthy fats for no reason. (1) (A pro tip? If you're planning on doing the diet, consider perusing this complete keto food list and reading up on the healthiest fats for keto diet followers.)

There's not a lot of reliable information available about how the military diet plan was started — or, for that matter, who started it. MilitaryDiet.co and TheMilitaryDiet.com, the two main resource sites for the diet regimen, are both run by fans and proponents of the diet without any cited health professional credentials. According to them, though, the military diet plan is an intermittent fasting diet that combines three days of a strict, low-calorie meal plan with four days of eating whatever you want (as long as it still falls below the calorie intake).

A 2014 Harvard study found that men who did twenty minutes of daily weight training had less of an increase in age-related abdominal fat compared with men who spent the same amount of time doing aerobic activities, and other studies have shown similar levels of success when guys hit the gym to cut down on fat. The implication: Guys can cut belly fat most efficiently with weight training.


Breakfast on day 1 includes grapefruit, toast, peanut butter and coffee or tea. There are a range of important vitamins and minerals present in this meal.  Starting out with the grapefruit, you’ll get 28% of the Vitamin A and over half of your Vitamin C requirements for the day, all with just a half a grapefruit! Vitamin A is vital because it helps the body in a number of areas including vision, promoting healthy skin and mucous membranes, the immune system and bone/ tooth growth. The Vitamin C is equally important. Although it may stop short of curing the common cold, this vitamin does support your immune system and helps your body to absorb iron. Grapefruit packs in the nutritional value and also contains Vitamin B-6, potassium and plenty of fiber. Vitamin B-6 is important for protein metabolism and is also indispensable in forming new red blood cells (1), while potassium helps to maintain fluid balance in the body, supports nerve transmission and acts in muscle contractions as well (2). Finally, fiber is what keeps your digestive system moving and is essential in any diet; especially one focused on weight loss.
The 3 Day Military Diet sounds perfect for someone that is trying to fit into a smaller dress or suit before an upcoming class reunion, but not designed to sustain a healthy lifestyle over an extended period. The concept of smaller portions, exercise, and drinking plenty of water is a good idea, but I agree that low calorie diets can be dangerous. Thanks for the interesting post!
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.
Remember that it takes a 3500-calorie deficit to lose one pound of fat. That is, you have to either burn off 3500 calories through exercise or eat 3500 calories less than you burn in a week. Break this up into daily limits. To burn 3500 calories a week, you should aim to have a 500 calorie deficit every day. For example, you can exercise to burn 250 calories and cut 250 calories from your diet.
Based on calories, you need to cut out or burn 3500 calories to lose 1 pound . Multiply that by 10 pounds, and you’re talking about cutting out 35,000 calories in a week. That’s quite a bit! If we consider your eating habits, most people consume about 2000 to 2500 calories every day. On the Military Diet, you’re cutting back to about 1200 calories a day on the 3 Day diet, and probably around 1500-1700 calories on the 4 days off. That means just in calorie consumption, you’re cutting out about 1000 per day during the restricted portion of the diet.

Lunch on day 1 is packed with protein, fulfilling about 60% of your daily protein intake requirements just in the tuna. The tuna also contributes other vitamins including Vitamin A, B-12, B-6 and minerals including magnesium and iron. Vitamin B-12 is an important vitamin often found in fish that plays an important role in the creation of new cells. It’s also important for nerve function. (1) The bread offers carbohydrates and plenty of fiber.
Big salad of baby greens with Pritikin-Style Thousand Island Dressing, which has less than one-quarter the calories and sodium of regular Thousand Island Dressing. What a gift for your heart and waistline! To make dressing, combine thoroughly the following: ¾ cup plain fat-free Greek yogurt, ½ cup fat-free sour cream, ¾ cup unsweetened, low-sodium ketchup (good brand is Westbrae), ½ teaspoon oregano, and ½ teaspoon granulated garlic.
Probably, and there are a few reasons why, Keatley says. For starters, people usually reduce their daily caloric intake to about 1,500 calories a day because healthy fats and lean proteins make you feel fuller sooner—and for a longer period of time. And then there’s the fact that it takes more energy to process and burn fat and protein than carbs, so you're burning slightly more calories than you did before. Over time, this can lead to weight loss.
Implementing the diet can present difficulties for caregivers and the patient due to the time commitment involved in measuring and planning meals. Since any unplanned eating can potentially break the nutritional balance required, some people find the discipline needed to maintain the diet challenging and unpleasant. Some people terminate the diet or switch to a less demanding diet, like the modified Atkins diet (MAD) or the low-glycaemic index treatment (LGIT) diet, because they find the difficulties too great.[41]
Implementing the 80/20 rule is the only way you'll be able to sustain a healthy lifestyle for the rest of your life and enjoy it! "What's the point of getting in a better shape if it will make all other areas of your life worse, don't you agree?" Ivica said. You're eating right and exercising to lose weight to enhance your life — never forget that! So the method to get there shouldn't negatively impact your life.
