2) Now you need to do a little learning before we move any further. Start by learning a bit more about ketosis itself, and the pitfalls you need to watch out for.  I love Bodybuilding.com and think that this article on the Keto Diet is perfect for beginners, so go check it out. Unless you are planning to start bodybuilding part, 2 of the article will not apply to you. 😉
It usually takes three to four days for your body to go into ketosis because you have to use up your body's stores of glucose, i.e., sugar first, Keatley says. Any major diet change can give you some, uh, issues, and Keatley says he often sees patients who complain of IBS-like symptoms and feeling wiped out at the beginning of the diet. (The tiredness happens because you have less access to carbs, which give you quick energy, he explains.)
Hi Sia, welcome to the wonderful world of keto! I would start simple – eat whole foods like avocado, protein, and dark veggies. Download MyFitnessPal or CarbCounter apps to track your macros for you. What works best for me is planning out my meals ahead of time. Ill meal prep my food then log it into MyFitnessPal app so I know I am on target then the next day, eat only what I’ve logged. Its the perfect way to make sure you have enough food that already prepared and the best way to stick to macros. Hope that helps!

Can’t you take ketone supplements? No. While it is possible to elevate ketones by taking them, “without the low-carb stimulus, there is no net increase in ketone production, no decrease in insulin, and no net increase in fat oxidation,” says Volek. Don’t trust trainers or “body hackers” who say you can induce ketosis quickly without changing your diet.


There are two major ways fasting is beneficial for overall health. First, it gives the body a break from digestion. Digestion is a surprisingly stressful activity, and if there is a longer period of time where your body can focus on simply using the nutrients it’s been given already without having to handle more, digestion tends to improve, as well as energy levels.

•Sodium: Believe it or not, depending on your diet, you may be low on salt. When carb intake is low and insulin isn't being excreted, the kidneys absorb less sodium and potassium and excrete more as waste, leaving you feeling dizzy, fatigued and grumpy. Rather than reaching for more processed food, try seasoning your food a little more liberally with sea salt.
Quick update – been doing a keto-type diet for a couple of months now. My BP is down to the lowest it’s been in something like 10 years, though still on 1/2 dose for my meds. I’ve lost about 30 pounds in the last 4 months (give or take a bit as I’m not sure exactly where I started). I’ll admit I still use Truvia and will have a Coke Zero every now and then, but eliminating the wheat and corn breads and sugars to reduce my carb intake to < 50g/day on average has made a huge difference. (I'm sure some still sneaks in with some of the food I eat out, but for the most part it's pretty good.)

The biggest draw for me is how many of those who’ve tried it say they don’t get hungry. The possibility of that blows my mind, as someone who’s used to any sort of calorie restriction meaning hours of feeling hungry every day. It’s tantalizing enough that I at least want to try. And what have I got to lose, right? I’m already morbidly obese; it’s hard to imagine screwing this up so bad it makes that worse.

Symptoms of the keto flu include headache, fatigue, dizziness, sleep problems, heart palpitations, cramps, and diarrhea. These side effects usually lessen and eventually resolve in about two weeks. (2) But to lessen the effects of any discomfort, simply consider slowly transitioning onto a ketogenic diet rather than rushing to change your eating habits. By slowly lowering your carbohydrate intake, while gradually increasing your intake of dietary fat over time, you can transition with less of a negative impact and potentially prevent the keto flu.

At 4 weeks you should be feeling pretty darn good.  If you are feeling better, but not awesome, give it a little more time.  If you have not felt better throughout this time and have stuck strictly to your low carbs and high fat, your body may not align with the keto diet.  If you only feel bad because you're craving bad food, this may be a mental "block" that you need to deal with.  Coaching can help.


Paleo and keto can overlap, though there are some major differences in the core of each way of eating. The Paleo diet focuses on whole, natural foods that would have been available as food to our paleolithic ancestors. If it could have been hunted or foraged, then it would have been eaten. Some people on a Paleo plan also focus on what would have been growing in season, and in a certain region of the world for their genetic ancestors. Carbs are overall allowed in a Paleo plan, but they would come from whole foods like potatoes, sweet potatoes, fruits, honey, and other unprocessed sources.
There are variations of the ketogenic diet that are implemented for a variety of reasons.  One of the top reasons these variations are used are for athletes who are not getting the necessary energy required for their intense workouts.  There are also those who enjoy the benefits of ketosis, but they just do not feel the same without a carb refeed day every now and then.
Anecdotally speaking, people do lose weight on the keto diet. Heather Wharton, a 35-year-old business relationship manager from Tampa, Florida, lost 140 pounds since starting the keto diet in January 2016: “I plan on being on the keto diet for the rest of my life,” says Wharton. “My husband and I consider ourselves to be food addicts, and the keto diet is what we use as a form of abstinence from trigger foods that have sugar and other carbohydrates." A typical day of eating for Wharton includes coffee with a protein supplement, a cup of unsweetened cashew milk, cauliflower rice with ground turkey and liquid aminos (a carb-free substitute for soy sauce), spinach, six slices of turkey bacon, six eggs, and a little salsa.

The second tip is to “carb-up”, meaning to eat high fat, low carb all day, and at night basically eat all carbs, no fat. Carbs like sweet potatoes, plantains, and grains, are some of the prefered foods when practicing “carb-up”. The reason why the “carb-up” practice can be helpful is because, once you are fat-adapted, your body burns carbohydrates first, and then goes into the fat-burning mode but, once you increase the amount of carbs eaten, your body’s ability to better burn fat is increased. To sum up “carb-up”: helps you go from fat-adapted back to the fat-burning mode.

Something that makes the keto diet different from other low-carb diets is that it does not “protein-load.” Protein is not as big a part of the diet as fat is. Reason being: In small amounts, the body can change protein to glucose, which means if you eat too much of it, especially while in the beginning stages of the keto diet, it will slow down your body’s transition into ketosis.

On a keto diet, weight loss can often be substantial and happen quickly (especially for those who start the diet very overweight or obese). The 2013 study published in the British Journal of Nutrition found that those following a keto diet “achieved better long-term body weight and cardiovascular risk factor management when compared with individuals assigned to a conventional low-fat diet (i.e. a restricted-energy diet with less than 30 percent of energy from fat).” (4)
Basically, when you have alcohol in your body, the first thing that will be burnt is the alcohol. Only then, can your body begin to burn carbohydrates, and ultimately move on to fat-burning mode. By consuming small amounts of alcohol, the alcohol will be burnt quite fast and then move on to burning carbohydrates. The biggest tip here is to only include alcohol in your diet once your body is fully adapted to a high-fat diet.
• Reducing appetite — Constant hunger can cause you to consume more calories than you can burn, which can eventually lead to weight gain. A ketogenic diet can help you avoid this problem because reducing carbohydrate consumption can reduce hunger symptoms. In one study, participants who were given a low-carbohydrate diet had reduced appetites, helping them lose weight easier.2

Totally agree that it’s not something for everyone, though. Even one of the authors I read said he sometimes sneaks a french fry or a bite of cheesecake/ice cream, though he’s able to stop after just a little bit and it doesn’t throw him off horribly. Of course, that’s not license to eat junk all the time, but it does mean that once you’re well-adapted, you can sometimes indulge.


You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.
Hi Emily, I was also really nervous about the amount of fat when I first started too! Just trust it, give it a couple of weeks to work its magic and then you will definitely feel more comfortable! I actually used a couple of online calculators for macros and took the average of what they all said. When starting keto, remember your net carbs should be under 20 grams, so use that as a guideline when calculating the rest of your macros. Let me know if you need anything else!

Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
• Keto "Flu": Your body isn't accustomed to using ketones on the regular, so when you make the switch, you tend to feel unwell. The keto diet also influences electrolyte balance, resulting in brain fog, headaches, nausea and fatigue. Keto dieters also consistently complain about getting bad-smelling breath, sweat and pee as a result of the by-product of fat metabolism (acetone) seeping out. Thankfully, this effect is just temporary, so just know you won't have to spend your life smelling rank.
The ketogenic diet is super high in fat (about 80 percent of your daily calories), super low in carbohydrates (less than 5 percent of your calories), and moderate in protein (typically 15 to 20 percent of your calories). This is a pretty drastic departure from the generally recommended macronutrient distribution of 20 to 35 percent protein, 45 to 65 percent carbohydrates, and 10 to 35 percent fat.

"Long-term effects of a ketogenic diet in obese patients"
The ketogenic diet — a high-fat and very low-carb eating plan — can be tough to start. After all, it’s likely a radical departure from the way you’re eating now (a typical standard American diet is high in carbohydrates and processed foods). But many people are trying the keto diet, which puts your body in a state of ketosis. That's what happens when your body’s carb-burning switch flips to a fat-burning one, a change that can cause weight loss and has even been credited with controlling diabetes. (1)
