Health Benefits of Low-Carb and Ketogenic Diet 1. Low-Carb Diets Kill Your Appetite in a Good Way
Hunger is the single worst side effect of dieting. It is one of the main reasons
why many people feel miserable and eventually give up on their diets. One of the
best things about eating low-carb is that it leads to an automatic reduction in
appetite.
The studies consistently show that when people cut carbs and eat more protein
and fat, they end up eating much fewer calories. In fact� when researchers are
comparing low-carb and low-fat diets in studies, they need to actively restrict
calories in the low-fat groups to make the results comparable.
2. Low-Carb Diets Lead to More Weight Loss
Cutting carbs is one of the simplest and most effective ways to lose weight.
Studies show that people on low-carb diets lose more weight, faster, than people
on low-fat diets� even when the low-fat dieters are actively restricting
calories.
One of the reasons for this is that low-carb diets tend to get rid of excess
water from the body. Because they lower insulin levels, the kidneys start
shedding excess sodium, leading to rapid weight loss in the first week or two.
In studies comparing low-carb and low-fat diets, the low-carbers sometimes lose
2-3 times as much weight, without being hungry.
Low-carb diets appear to be particularly effective for up to 6 months, but after
that the weight starts creeping back up because people give up on the diet and
start eating the same old stuff. It is much more appropriate to think of
low-carb as a lifestyle, NOT a diet. The only way to succeed in the long-term is
to stick to it. However, some people may be able to add in healthier carbs after
they have reached their goal weight.
3. A Greater Proportion of The Fat Lost Comes From The Abdominal Cavity
Not all fat in the body is the same. It�s where that fat is stored that
determines how it will affect our health and risk of disease. Most importantly,
we have subcutaneous fat (under the skin) and then we have visceral fat (in the
abdominal cavity).
Visceral fat is fat that tends to lodge around the organs. Having a lot of fat
in that area can drive inflammation, insulin resistance and is believed to be a
leading driver of the metabolic dysfunction that is so common in Western
countries today.
Low-carb diets are very effective at reducing the harmful abdominal fat. Not
only do they cause more fat loss than low-fat diets, an even greater proportion
of that fat is coming from the abdominal cavity. Over time, this should lead to
a drastically reduced risk of heart disease and type 2 diabetes.
4. Triglycerides Tend to go Way Down
Triglycerides are fat molecules. It is well known that fasting triglycerides,
how much we have of them in the blood after an overnight fast, are a strong
heart disease risk factor.
Perhaps counter intuitively, the main driver of elevated triglycerides is
carbohydrate consumption, especially the simple sugar fructose. When people cut
carbs, they tend to have a very dramatic reduction in blood triglycerides.
Compare this to low-fat diets, which can cause triglycerides to go up in many
cases.
5. Increased Levels of HDL (the �good�) Cholesterol
High Density Lipoprotein (HDL) is often called the �good� cholesterol. It�s
actually wrong to call it �cholesterol�� all cholesterol molecules are the same.
HDL and LDL refer to the lipoproteins that carry cholesterol around in the
blood.
Whereas LDL carries cholesterol from the liver and to the rest of the body, HDL
carries cholesterol away from the body and to the liver, where it can be reused
or excreted. It is well known that the higher your levels of HDL, the lower your
risk of heart disease will be.
One of the best ways to increase HDL levels is to eat fat� and low-carb diets
include a lot of fat. Therefore, it is not surprising to see that HDL levels
increase dramatically on low-carb diets, while they tend to increase only
moderately or even go down on low-fat diets. The Triglycerides:HDL ratio is
another very strong predictor of heart disease risk. The higher it is, the
greater your risk of heart disease is.
By lowering triglycerides and raising HDL levels, low-carb diets lead to a major
improvement in this ratio. Bottom Line: Low-carb diets tend to be high in fat,
which leads to an impressive increase in blood levels of HDL, often referred to
as the �good� cholesterol.
6. Reduced Blood Sugar and Insulin Levels, With a Major Improvement in Type 2
Diabetes
When we eat carbs, they are broken down into simple sugars (mostly glucose) in
the digestive tract. From there, they enter the bloodstream and elevate blood
sugar levels.
Because high blood sugars are toxic, the body responds with a hormone called
insulin, which tells the cells to bring the glucose into the cells and to start
burning or storing it.
For people who are healthy, the quick insulin response tends to minimize the
blood sugar �spike� in order to prevent it from harming us. However� many, many
people have major problems with this system. They have what is called insulin
resistance, which means that the cells don�t �see� the insulin and therefore it
is harder for the body to bring the blood sugar into the cells.
This can lead to a disease called type 2 diabetes, when the body fails to
secrete enough insulin to lower the blood sugar after meals. This disease is
very common today, afflicting about 300 million people worldwide. There is
actually a very simple solution to this problem� by cutting carbohydrates, you
remove the need for all of that insulin. Both blood sugars and insulin go way
down.
According to Dr. Eric Westman, who has treated many diabetics using a low-carb
approach, he needs to reduce their insulin dosage by 50% on the first day. In
one study in type 2 diabetics, 95.2% had managed to reduce or eliminate their
glucose-lowering medication within 6 months.
If you are currently on blood sugar lowering medication, then talk to your
doctor before making changes to your carbohydrate intake, because your dosage
may need to be adjusted in order to prevent hypoglycemia. The best way to lower
blood sugar and insulin levels is to reduce carbohydrate consumption. This is
also a very effective way to treat and possibly even reverse type II diabetes.
7. Blood Pressure Tends to go Down
Having elevated blood pressure (hypertension) is an important risk factor for
many diseases. This includes heart disease, stroke, kidney failure and many
others. Low-carb diets are an effective way to reduce blood pressure, which
should lead to a reduced risk of these diseases and help you live longer.
Studies show that reducing carbs leads to a significant reduction in blood
pressure, which should lead to a reduced risk of many common diseases.
8. Low-Carb Diets Are The Most Effective Treatment Known Against Metabolic
Syndrome
The metabolic syndrome is a medical condition that is highly associated with the
risk of diabetes and heart disease.
It is actually a collection of symptoms:
Abdominal obesity
Elevated blood pressure
Elevated fasting blood sugar levels
High triglycerides
Low HDL levels
The good news is� all five symptoms improve dramatically on a low-carb diet
Unfortunately, the government and major health organization still recommend a
low-fat diet for this purpose, which is pretty much useless because it does
nothing to address the underlying metabolic problem. Low-carb diets effectively
reverse all 5 key symptoms of the metabolic syndrome, a serious condition known
to predispose people to heart disease and type 2 diabetes.
9. Low-Carb Diets Improve The Pattern of LDL Cholesterol
Low Density Lipoprotein (LDL) is often referred to as the �bad� cholesterol
(again, it is actually a protein). It is known that people who have high LDL are
much more likely to have heart attacks.
However� what scientists have now learned is that the type of LDL matters. Not
all of them are equal. In this regard, the size of the particles is important.
People who have mostly small particles have a high risk of heart disease, while
people who have mostly large particles have a low risk. It turns out that
low-carb diets actually turn the LDL particles from small to large, while
reducing the number of LDL particles floating around in the bloodstream.
When you eat a low-carb diet, your LDL particles change from small (bad) LDL to
large LDL � which is benign. Cutting carbs may also reduce the number of LDL
particles floating around in the bloodstream.
10. Low-Carb Diets Are Therapeutic For Several Brain Disorders
It is often claimed that glucose is necessary for the brain� and it�s true. Some
part of the brain can only burn glucose. That�s why the liver produces glucose
out of protein if we don�t eat any carbs. But a large part of the brain can also
burn ketones, which are formed during starvation or when carbohydrate intake is
very low.
This is the mechanism behind the ketogenic diet, which has been used for decades
to treat epilepsy in children who don�t respond to drug treatment. In many
cases, this diet can cure children of epilepsy. In one study, over half of
children on a ketogenic diet had a greater than 50% reduction in seizures. 16%
of the children became seizure free.
Very low-carb/ketogenic diets are now being studied for other brain disorders as
well, including Alzheimer�s disease and Parkinson�s disease.
Ketogenic diets are NOT high protein diets. They are high fat diets. Protein
intake is moderate and only small amounts of carbohydrates are allowed. A
typical ketogenic meal includes a 3-5 ounces of protein, usually cooked in
natural fats (for example, butter, beef tallow, lard, duck fat, cream, olive
oil, or coconut oil) and green leafy vegetables.
When carbohydrate foods are digested, they are broken down into blood sugar
(glucose) in the body. The more carbs we eat, the more glucose is created. If we
reduce carb intake and instead eat more fat and protein, it causes our internal
metabolic pathways to switch from burning sugar to burning fat.
This switch produces ketone bodies while at the same time reducing blood sugar
and insulin levels. As blood glucose and insulin levels drop and ketone body
levels rise, the heart, muscle and brain reduce use of glucose and instead use
fats and ketones to fuel themselves. This state of "nutritional ketosis" is
beneficial, and in fact, ketone producing diets are much more powerful than most
people realize.
Ketogenic diets emphasize foods rich in natural fats and adequate in protein
(meat, fish, poultry) and restrict foods high in carbohydrate (sugars and
starches). The standard American diet (SAD) contains 45-65% of calories from
carbohydrate. Ketogenic diets restrict carbohydrate intake to about 2-4% of
calories.
The classic ketogenic diet is not a balanced diet and only contains tiny
portions of fresh fruit and vegetables, fortified cereals and calcium-rich
foods. In particular, the B vitamins, calcium and vitamin D must be artificially
supplemented. This is achieved by taking two sugar-free supplements designed for
the patient's age: a multivitamin with minerals and calcium with vitamin D. A
typical day of food for a child on a 4:1 ratio, 1,500 kcal (6,300 kJ) ketogenic
diet comprises:
Breakfast: egg with bacon
28 g egg, 11 g bacon, 37 g of 36% heavy whipping cream, 23 g butter and 9 g
apple.
Snack: peanut butter ball
6 g peanut butter and 9 g butter.
Lunch: tuna salad
28 g tuna fish, 30 g mayonnaise, 10 g celery, 36 g of 36% heavy whipping cream
and 15 g lettuce.
Snack: keto yogurt
18 g of 36% heavy whipping cream, 17 g sour cream, 4 g strawberries and
artificial sweetener.
Dinner: cheeseburger (no bun)
22 g minced (ground) beef, 10 g American cheese, 26 g butter, 38 g cream, 10 g
lettuce and 11 g green beans.
Snack: keto custard
25 g of 36% heavy whipping cream, 9 g egg and pure vanilla flavouring.
