There are mixed and matched studies on keto and breastfeeding, though nothing is well researched at the current moment. Right now it’s understood that ketogenic diets are typically healthy to do while breastfeeding.
Here’s one study that shows drops in lesions and skin inflammation when switching to a low-carb diet. Another study that shows a probable connection between high-carb eating and increased acne, so it’s likely that keto can help.
Collagen is a type of protein — 1 of over 10,000 in your body. Collagen is the most abundant protein in your body, accounting for 25-35% of all protein. It can be considered the glue that holds your body together as it supports the growth of joints, organs, hair, and connective tissues..
The keto diet can reduce the risk of heart disease markers, including high cholesterol and triglycerides. (6) In fact, the keto diet is unlikely to negatively impact your cholesterol levels despite being so high in fat. Moreover, it’s capable of lowering cardiovascular disease risk factors, especially in those who are obese. (7)
The ketogenic diet reduces seizure frequency by more than 50% in half of the patients who try it and by more than 90% in a third of patients.[3] Three-quarters of children who respond do so within two weeks, though experts recommend a trial of at least three months before assuming it has been ineffective.[9] Children with refractory epilepsy are more likely to benefit from the ketogenic diet than from trying another anticonvulsant drug.[1] There is some evidence that adolescents and adults may also benefit from the diet.[9]

You may see some limitations on your performance when you first begin a keto diet, but it’s usually just from your body adapting to using fat. As your body shifts in using fat for energy, all of your strength and endurance will return to normal.
Also, it’s never a bad idea to catchup with your primary care physician to find out anything you need to know about your body. If you are on any kind of medication, you should consult with a doctor to check whether following a ketogenic diet could have any adverse effects.  Also, if you struggle to digest fats, keto might not be the right choice.
Ketoacidosis happens when your body fails to produce enough insulin (which is more commonly seen in those with type 1 diabetes, however it can also occur in those with type 2 diabetes if their diet and insulin levels aren’t being properly monitored (28).
If you’re still confused about what a net carb is, don’t worry – I’ll explain further. Let’s say for example you want to eat some broccoli (1 cup) – seriously my favorite and most delicious vegetable out there.

To start a keto diet, you will want to plan ahead. That means having a viable diet plan ready and waiting. What you eat depends on how fast you want to get into a ketogenic state. The more restrictive you are on your carbohydrates (less than 15g per day), the faster you will enter ketosis.
In contrast, multivitamins aren’t a good solution as they are synthetic and lack a lot of nutrients like polyphenols, antioxidants, and fiber that green powders and whole food sources provide. And the lack of fats and enzymes make the nutrients they do contain very difficult to process properly. Just because you’re putting something in your body doesn’t mean your body can use it!
Nutrition data from the 1970s told us saturated fats are bad, causing the United States to enter the era of low fat. During this time, obesity in America soared while consumption of fat (particularly saturated fats) plummeted. Fad, low-fat diet products became the norm at grocery stores as a high-carb, low-fat diet became the preferred method for weight loss. Yet, people kept gaining weight.
The Keto diet has its roots in the decades-old therapeutic ketogenic diet. Clinically, the ketogenic diet is used in neurologic medicine, most notably to reduce hard-to-control seizures in children. Studies also suggest possible benefits in other brain conditions such as Parkinson’s and Alzheimer’s diseases.
My first week on the keto diet went remarkably well—as in, I wasn’t swearing like a sailor or drooling over every whole-wheat roll my friends popped into the toaster. However, the influx of cravings and insatiable hunger I experienced toward the end of my experiment made me realize that this diet isn’t very sustainable.
Today, new studies show that fats are not the real culprit[*]. A ketogenic diet dispels the “fat makes you fat” philosophy for several reasons. First, a diet high in carbs (especially refined and processed carbs from low-fat diet products) can increase insulin and blood sugar levels and promote inflammation in the body. In contrast, a low carb diet can help reduce inflammation far better than a low-fat diet[*].
The ketone bodies are possibly anticonvulsant; in animal models, acetoacetate and acetone protect against seizures. The ketogenic diet results in adaptive changes to brain energy metabolism that increase the energy reserves; ketone bodies are a more efficient fuel than glucose, and the number of mitochondria is increased. This may help the neurons to remain stable in the face of increased energy demand during a seizure, and may confer a neuroprotective effect.[55]
Last, but certainly not least, is sticking to the diet! Ketosis is a process that happens in your body. You can’t just have “that one” cheat meal. If you do, it can hamper progress for up to a week before your body is back in ketosis and normally functioning again.

Several lines of evidence point to beneficial effects of VLCKD on cardiovascular risk factors. In the past, there have been doubts expressed about their long-term safety and increased effectiveness compared with ‘balanced’ diets,25 and clearly negative opinions regarding possible deleterious effects on triglycerides and cholesterol levels in the blood.26 However, the majority of recent studies seem instead to amply demonstrate that the reduction of carbohydrates to levels that induce physiological ketosis (see above ‘What is ketosis?’ section) can actually lead to significant benefits in blood lipid profiles.15, 17, 27 The VLCKD effect seems to be particularly marked on the level of blood triglycerides,24, 28 but there are also significant positive effects on total cholesterol reduction and increases in high-density lipoprotein.24, 28, 29 Furthermore, VLCKD have been reported to increase the size and volume of low-density lipoprotein–cholesterol particles,29 which is considered to reduce cardiovascular disease risk, as smaller low-density lipoprotein particles have a higher atherogenicity. There are also direct diet-related effects on overall endogenous cholesterol synthesis. A key enzyme in cholesterol biosynthesis is 3-hydroxy-3-methylglutaryl–CoA reductase (the target for statins), which is activated by insulin, which means that an increase in blood glucose and consequently of insulin levels will lead to increased endogenous cholesterol synthesis. A reduction in dietary carbohydrate will have the opposite effect and this, coupled with the additional inhibition by dietary cholesterol and fats on endogenous synthesis, is likely to be the mechanism via which physiological ketosis can improve lipid profiles. Hence, there are strong doubts about the negative effects of dietary fats when they are consumed as part of a VLCKD, on cholesterol and triglycerides blood levels, whereas there are strong pointers to the beneficial effects of VLCKD on these cardiovascular risk parameters.27, 28
First, don’t mistake a ketogenic diet (or the upgraded Bulletproof Diet) for the Atkins Diet. Whereas the Atkins Diet is extremely high in protein, a keto diet contains moderate amounts of protein. On a keto diet, large amounts of protein can turn into glucose in a process called gluconeogenesis, thus taking you out of ketosis. That’s why fatty cuts of meat are better than, say, chicken breast, which is high in protein and low in fat. Vast amounts of protein also tax the liver and lead to inflammation. By contrast, a ketogenic diet is anti-inflammatory; burning fat for fuel creates far less inflammation than burning sugar does[2], and ketones themselves turn off inflammatory pathways[3]. Because of this, ketogenic diets may in fact help prevent chronic diseases that are caused by inflammation. (Fun fact: The ketogenic diet is used to keep epileptic patients from having seizures.)

“I recommend only 5 percent of calories coming from carbs, which usually averages out to less than 30 grams,” he says. “So, I understand why people get nervous and panic, thinking ‘Can I even eat a salad?’ This is why I recommend tracking only ‘net carbs’, which is total carbs minus fiber. For example, an avocado has 12 grams of carbs but 10 grams of fiber, which means it has 2 grams of net carbs. Also, green leafy vegetables are very nutritious and contain a lot of fiber, so you can almost eat them as much as you want and stay below your limit.”
In a fasting state, our bodies can break down extra fat that’s stored for the energy it needs. When we’re in ketosis, our body already mimics a fasting state, being that we have little to no glucose in our bloodstream, so we use the fats in our bodies as energy.
