Throughout the day we perform various activities. We are divided into work, college, exercise, home care, marriage and children. These activities are already part of the daily life of modern women and to be able to handle so many things to do it takes a lot of energy! Do you know where the energy we use to perform our daily activities comes from?
Ketosis: Do You Know What This Is?
Our primary sources of energy are found in carbohydrates. It is from the breads, cereals, rice and pasta present in our diet that metabolism takes the fuel needed to maintain and perform daily activities.
However, in a diet where carbohydrate is not present the body looks for other energy reserves, and fat (fatty acid) becomes the main source. Physical educator Cristiane Lima Dias explains that ketosis is a stage of catabolism (breakdown of substances such as proteins) that occurs when the pancreas converts proteins into fatty acids, and fat is used to generate energy for the body.
Ketosis is therefore a state in which the body, in the absence of carbohydrates in food for at least 3 days, uses body fat deposits and also the fat ingested through food as fuel for the body turning them into ketones or bodies. ketones. That is, being in Ketosis is to use body fat as energy.
Glucose versus Ketones
Glucose is a monosaccharide (simple sugar) used by the body to produce metabolized energy for cells. Insulin has the function of turning glucose into energy.
Like glucose, ketones are also a source of fuel and energy for the human body. When glucose / sugar is not found in the body, ketones are produced by the liver from fatty acids and result in the breakdown of body fat? and weight loss.
Ketogenic diet? Induced ketosis
Most people believe that losing weight is enough to get in shape. In traditional diets where you usually eat less than you spend the tendency is to lose weight and also lean mass / muscle. The result can be a leaner but weaker body. What about a diet that only loses fat while protecting lean mass? She exists!
Ketosis can aid in weight loss because it is caused by the lack of carbohydrates so the body then needs to utilize fat as its primary source of energy. One of the newest diets that promises rapid weight loss today is based on this principle, explains Cristiane. Assuming that not eating carbohydrates would result in the utilization of the body's fat reserves and consequent weight loss, the ketogenic diet emerged *.
The ketogenic diet or now known as the protein diet was popularized by cardiologist Dr. Robert Atkins in the 1920s. The goal of the diet would be to reduce body fat stores by inducing the ketosis process through low or no carbohydrate intake.
Being in ketosis means that your body's primary source of energy is fat. When you consume the proper protein, there is no need for the body to break down its own muscle tissue. Ketosis tends to accelerate fat loss when the liver converts fat to ketones, which cannot be converted back to fat, and is therefore eliminated as ketone bodies.
In the ketogenic diet carbohydrates are prohibited. The diet has gained popularity due to a menu with attractive options: protein, fat and fiber can be consumed:
- Filet Steak
- Salmon
- Bacon
- White cheese
- eggs
- Milk cream
- Pâté
- Ham
- Smoked turkey breast
- Mortadella
- Vegetables
- Olive oil
- Chestnuts
- Chicken
- Fish
- All types of meat including greasy like termite and titty.
But beware, it's not a miracle: "There are no benefits when you don't have a balanced diet and physical activity program," says Cristiane. If there is no balance or dietary education usually associated with these diets, the likelihood of gaining weight later is very high. Below is a list of the pros and cons of the diet.
Pros:
- Elimination of refined carbohydrates, which are those coming from foods prepared with sugar and refined wheat flour. This means: bread, pasta, snack foods, sweets, cake, ice cream, soda, etc .;
- Maintenance of lean mass;
- Lower appetite, lower desire for sweets, higher sodium elimination and lower fluid retention, improved premenstrual symptoms, marked reduction in total cholesterol and LDL, control of insulin resistance and greater efficiency of insulin action.
Cons:
- As a side effect, ketosis can cause nausea, fatigue, nausea and headaches, constipation;
- The buildup of ketones or ketone bodies in your body gives your breath an unpleasant odor, making the whole person smell like acetone;
- High protein diets pose health risks as they can produce short term weight loss through dehydration. Large amounts of water will be lost leading to the belief that a significant weight reduction is occurring.
Curiosities
Ketosis and Alcohol: Alcohol consumption does not compromise ketosis and even when drinking alcohol the liver continues to produce ketones normally. The problem is that alcohol converts more easily to ketones than fatty acids, so the liver will use all alcohol first, then fat. That is: the more alcohol is consumed, the less fat will be lost. Another detail: in ketosis it is much easier to get drunk.
Diabetes and Ketosis: The difference between Ketosis and Ketoacidosis: The word ketosis is commonly confused with ketoacidosis. Ketoacidosis happens when blood pH becomes acidic due to a high blood sugar level:? Diabetic ketoacidosis can occur in type 1 and 2 diabetes, caused by a? Acidity? in the blood, which is lower than normal ph because of the accumulation of ketone bodies? result of lack of insulin because the body has no glucose to use as a source of energy, explains Cristiane. Sugar rises and ketones continue to be produced by the body to provide the necessary fuel as cells cannot use sugar. It is high blood sugar, and the acidic condition provided by this hyperglycemia that provide a dangerous condition for diabetics.
Ketosis and Dengue: When not controlled dengue can produce ketosis. In this situation ketone bodies are considered dangerous. Tests should be done to detect the problem.
Attention! Before opting for a ketogenic diet, it is advisable to seek guidance and follow-up from a physician, nutritionist or physical educator. * The diet is known by various names: ketone, ketone, ketogenic, protein diet.
