Guest post: How does the Ketogenic diet work?

Guest post by Ricard Ponsi of Workout-Temple

Nutritional ketosis is a dietary protocol whose objective is to improve our metabolic flexibility when using fatty acids as the main energy substrate. For this, the intake of carbohydrates is limited, depending on the individual, approximately 50 g net per day.

With this we generate low levels of insulin in plasma and, subsequently, a reduction of glycogen levels in muscular and hepatic reserves. In the absence of the main fuel of our body (glucose) the ketogenesis process is activated, where the liver will produce ketone bodies to feed the different tissues and cells.

KETOSIS is a NATURAL state that human beings have experienced since the beginning of time. Therefore, we are evolutionarily adapted to use both energy substrates (ketone bodies and glucose), which means that past civilization may have consciously sought a state of fasting or induced ketosis. This is why, evolutionarily speaking our physiology seeks an alternative mechanism to glucose as it is the only source of energy.

Nutritional ketosis and metabolic flexibility

We can define the metabolic flexibility as the efficiency of our body when using energy substrates depending on demand such as walking, running or sprinting. Remember that, although our glycogen reserves (both muscular and hepatic) are limited, the same is not true of our fat stores, the latter being able to represent a much greater amount than the former. So… Why doesn’t our body use fats? What happens is that in a traditional diet based on hydrates (and not always from the best sources) our body always finds plasma glucose and glycogen stores full. Therefore, it does not need to look for any other energy source. Our body has simply ‘forgotten’ how to use fats as energy. It is here when the ‘low carb’ or ‘ketogenic’ guidelines are an interesting tool.

Adaptation to a new fuel

It is the process called Ketoadaptation, which we could define as the process through which human metabolism adapts to the use of fats optimally as the main source of energy. In the beginning a drastic change it can condition sports performance and your daily life, but in most of the cases the symptoms are diluted after the first week.

Symptoms of Keto-adaptation:

– Fatigue
– Worse sports performance
– Dizziness
– Cramps
– Constipation
– Palpitations

Once past the moment of adaptation we will see how the symptoms disappear, signal that our metabolism works optimally and achieving efficiency in both our sports and personal performance.

Very important considerations

Ketosis is NOT a pathological state. And I must emphasize this because, in a still very widespread way, nutritional ketosis is often confused with diabetic ketoacidosis.

Many symptoms may be due to a lack of electrolytes during the beginning of the ketosis process. There is a reduction in glycogen levels and, as a consequence, also a loss of water associated with this glycogen. With this loss of water there will be a ‘drag’ of electrolytes that we should know and replace, with special emphasis on 3 of them.

– Sodium DRI = 5000 – 7000 mg
– Potassium DRI = 1000 – 3500 mg
– Magnesium DRI = 300 – 500mg

I must emphasize that nutritional ketosis is NOT a hyperproteic diet, but moderate or protein-adjusted. The amount of protein is maintained at constant values depending on the objectives of the subject, and can range between 1.4 to 2.0 g / kg body weight.

Ketosis and sports performance

Resistance discipline: In this type of activities there are promising investigations and cases of ketoadapted athletes where the fat / glycogen use ratio is optimized, which positions as a great tool to maximize performance. Nutritional ketosis improves fat oxidation and metabolic flexibility, which is vital in long-term efforts where the main energy system is aerobic.

Discipline of strength: In disciplines where the main component is strength and power, the dominant energy substrate is the path of phosphogens, which is not impacted by a nutritional ketosis.

Hypertrophy training: This modality seeks to increase the total volume (series and repetitions) so the glycolytic pathway is a very important metabolic pathway. Since nutritional ketosis reduces muscle glycogen levels and also circulating insulin, it makes sense to think that it is not the optimal state to build muscle mass.

Conclusion on keto diet

In my opinion, the ketogenic diet can be an interesting strategy to introduce in periods of 6 to 10 weeks (a couple times a year) and benefit greatly from its effects.

During the intervention time there are very notable improvements in fat loss (extensive benefits proven), while maintaining the muscle mass and keeping performance levels measured through RM in different exercises.

Guest post: Common Keto Mistakes and How to Avoid Them

I understand, it’s hard for you to gauge your progress when you’ve only followed the ketogenic diet for a week or two, or even a whole month. The magic happens internally, and the only way for you to record your progress is using the weighing scale or measuring parts of your body (and how you feel too, to an extent).

A lot of beginner’s screw things up at the beginning once they realize things aren’t as straightforward as it was thought to be.

Here are some common keto mistakes beginners make and how YOU should avoid them, so your keto journey doesn’t have to go through hiccups and you can maintain your ketosis stage.

Obsessing over the scale!!!

If you’re stepping on the scale when you wake up, before lunch, after lunch, and after dinner, then STOP! This obsession will only lead to disappointment. Your weight changes throughout the day, especially after meals.

When you’re frequently disappointed, you’ll start to self-doubt that may lead you to throwing in the towel.

Sure, you’re on a low-carb diet … But you really think your weight isn’t gonna change after a meal? Be reasonable!

The best time to step on the scale is the morning when you wake up. If possible, every morning, around the same time for consistency. Keep it fair to yourself, and don’t fret too much about the digits on the scale! Write down what you see every morning for the next few weeks.

Once you see a pattern emerging, you’ll thank yourself for doing this.

Too much meat, bro

Yeap, too much protein can be counter-productive for you in a keto diet. When you’re in a low-carb diet, your liver can convert amino acids into glucose for energy, in a process called gluconeogenesis. Fancy, huh?

Remember, the point of entering ketosis is to prevent the body from using glucose as a main energy source. The protein you consume should only be enough to maintain muscle mass.

You should be keeping your daily protein intake below or at 1 gram of protein per day, per kg of body weight. So, if you weight 60 kilograms (133lbs.), keep your protein at 60 grams a day.

A good place to estimate your keto macronutrient needs that suit your goals is by using a keto macro calculator (like this one from Perfect Keto.)

The wrong mentality

A lot of people start with a diet to lose weight in a short period of time. It is possible, but you must be realistic.

An internet “guru” can claim that he lost 15 lbs within the first week of a diet he discovered (followed by a link to a course you have to buy), just as I can claim I have found the eternal cure to cancer. Don’t be fooled by these crazy marketing claims.

If done right, you can lose a lot of weight (2-10 lbs) within the first week, because your body loses WATER WEIGHT, not fat. And this too, depends on so many factors such as your metabolism, how active you are, and so on.

In the medium term, due expect weight loss of only 1-2lbs a week, and even a slower rate in the long term. You can’t get discouraged. Following a ketogenic diet is a lifestyle and a commitment in the long run. When you’re not there mentally, you’re gonna give in to sugar cravings and the hunger, which will kick you out off ketosis!

Taking the wrong types of fats/proteins

Keep your fats in check. Fats are a necessary part of a keto diet, but not all fats are good. Processed fats, such as hydrogenated oils and partially hydrogenated oils in junk food, fast food, and margarine should be avoided.

Avoid processed vegetable oils such as sunflower oil, corn oil, canola oil soybean oil, and a few others.

The best proteins to take on a Keto diet are plant-based proteins, not to say you can’t have animal meats, though. Too much fatty meat has been linked to heart diseases and high cholesterol levels. You should not follow a ketogenic diet just to lose weight, but to have a healthier life in the long run.

Keto protein supplements are a great way for you to meet your protein needs when it’s not convenient for you’re a strict-protein diet.

Take-Home Message

To every keto beginner out there, you need to have a lot of patience and commitment. Do your research, stick to your plan, be honest to yourself, and the results will come forth. As mentioned, you may lose a lot of weight initially, but don’t expect it to be like that the following weeks!

Guest post: Benefits of Portion Control

Overeating is a common habit these days. People don’t realize that they are overeating. Larger portions have more calories obviously and make you eat more. It causes problems like obesity, diabetes, etc. So, if you are looking for a healthy lifestyle, portion control should be a priority for you.

Practicing portion control can help you to be satisfied by eating less food, which is beneficial for you, both physically and financially.

Here are a few benefits of portions control that can encourage you.

1. Digestion Improvement:
   Portion Control can help you improve your digestion and metabolism by not overeating with lots of food in every meal. It will assist in weight-loss as well because your portions will be smaller and the ingestion will be able to take place smoothly.
2. Helps in Managing Calorie Intake:
   To lose weight, you need to burn more calories than you consume. When you are practicing portion control, you would want to eat something that would keep you full for some time since the portions are small.
   Bulking your meals with vegetables, oats, and fruits is one of the easiest ways to manage portion control because they fill you up and are calorie free!
   A proper amount of healthy food will supply your body with essential elements without eating extra.
   Practicing portion control will help in managing calorie intake and it also helps in maintaining blood glucose control. It is well-noted fact that increase in our waist size is directly proportional to insulin resistance. Insulin resistance is closely related to diabetes.
3. Money Saving:
   It’s pretty evident that when you eat smaller portions, you tend to spend less money. You also save money that you spend on junk food because when you practice portion control, you plan to eat healthy food to keep you full instead of junk food, that makes you crave for more and adds to binge-eating.
4. Increase in Your Satiety:
   It might sound strange but it is a fact, eating less makes you feel full. When you eat less, your stomach shrinks with time, and the feeling of satiety comes quick. Thus you prevent overeating.
5. Increased Energy:
   Research says that eating smaller portions boosts people’s energy and productivity. Eating irregular meals can lead to problematic issues like a feeling of depleted energy and irregular eating habits. Having increased strength will also help you engage in physical activity, which is essential for good health.
6. Helps Fight Illness:
   Smaller meals that are taken throughout the day help fight certain illnesses. Eating smaller portions with healthy ingredients give a better regulation of blood glucose levels and is linked to reducing cholesterol and chances of diabetes.

Guest post: Useful food eye-opener on healthy eating by Colin Campbell

Can one and the same nutrient budget be allowed for everyone? Why can even the best vitamin supplements not replace apples and spinach? What oxidation is and how animal albumen and foods of plant origin influence on it? What is the problem of modern researching? Colin Campbell answers these and many more questions in his The China Study bestseller.

Perfect ration

Those products, which are useful for some reason, are considered to be not tasty and not interesting. People think it to be boring but it is not like that. Evolution programmed us to enjoy food, which strengthens our health. A perfect ration is like this: vegetable food, as whole as possible. Eat different vegetable, fruits, nuts and seeds, beans and whole grains. Avoid strongly processed and foods of animal origin. Stay away from salt, fats, and sugar. Strive for getting 80% of calories from carbohydrates, 10% from fats and 10% from proteins.

This is it. This is what whole plant-based diet is, sometimes a lifestyle.

Be more specific, more actions

Look at such words as medicine and health in a different way. Health means more than a few superficial expressions like eat healthily, do not binge drink, do not use an elevator but use the stairs. It is all good but they do not include a possibility of actual changes. Those are ethical expressions with no specific and content.

It is important not just to follow a diet during a certain period of time but to change eating habits and stick to these changes during the lifetime. Those people who changed their eating habits and started eating healthy noticed that wrong product they consumed daily caused all the problems they have had before. Odd uncontrolled oxidation is an enemy of health and longevity just like overmuch oxidation makes it to where a new car turns into the junk heap, and a piece of an apple into a compost. Free radicals appear in the process and they are responsible for getting old, cause cancer and atherosclerotic plaque leading to heart attacks and cerebral accidents.

About modern research studies

There is a story about 6 blind men who were describing an elephant. Needless to say, that each of them describes it in their own way. They argue upon which of the descriptions is right. This is the best metaphor for the modern research studies problem. The only difference is that there are 60 000 researchers instead of 6 and each of them look at a problem through the lens of their own.

Medicine with no side effects

What you eat has more influence on your health than DNA and the major amount of harmful substances. Food can get you healthy faster and more effective than the major number of expensive medicine and most serious surgical operations. At that, side effects are going to be pleasant. Eating healthy, many diseases are easy to avoid, cancer, cardiac disease, diabetes mellitus type II, macular dystrophy, blind headache, erectile dysfunction and arthritis and this list is far from full. It is never too late to stop eating healthy. The healthy diet may help to avoid all these diseases.

An apple instead of a pill

We got used to taking food in the context of separate necessary elements. We eat carrot in order to get vitamin A, oranges for vitamin C, drink milk because there is calcium and vitamin D. If we like a product, we will get digestible nutrients with pleasure but if we do not like something, spinach, brussels sprouts, or sweet potato, we think that we can live without it, if to find some other product with the similar substance content to replace. But, for example, an apple gives more than just a sum of elements it contains. Nevertheless, due to the reductive worldview, we cannot believe that food is important in general and not only its substance content.

One approach for all

Medical community repeats oftentimes that one approach does not work for all. Nature organized our biological functions way better than we would most like to think but it is very important in terms of holistic nutrition.

No magic

Magic solutions are advertised as fast, easy and troublefree, which is why they are more realistic, requiring time, affords, and difficult for understanding. Notice that when it comes to advertisement, much is given preference to magic, from extra weight and financial services to cleaning and cosmetics. The more magical a product is, the easier it is to sell it and all the more so it feels like buying it. Magical solutions work with symptoms but not with causes. Symptoms are easy to clear; work with causes take more time. Fast clearance of isolated symptoms is the easy thing. Causes are more difficult and require more affords and responsibility on the part of a human. So, the holistic solution is for cardiovascular disease, diabetes, and extra weight. It removes the source: attempts of our body to cope with reworked and animal products. In spite of the fact that it may give more than a pill, an injection or operation, they should be followed all the time.

The force of superstition

There are many superstitions. Firstly, concerning proteins. Society believes that milk and meat are valuable and it is difficult to imagine that these products may cause harm. It is far from what we were taught for years to be true and it does not matter how much is true about it. Secondly, a paradigm of reductionism due to which we are focused on parts separate and excising the whole thing. A body is a holistic system with many inner connections but we got accustomed to thinking it to be a set of separate parts and systems where chemical substances make transformations apart from each other. Through the paradigm of reductionism, we see a nutrition as a sum of separate nutrients actions but not a universal process and consider dietology an isolated discipline and not the most influential factor of our health in general. Thirdly, profit-oriented system, which condemns to  reductionism. Unlike holism, it gives simple, fast and merchantable solutions aimed to one out of thousand potential problems. The industry remains the force determining what scientific tasks to pose, what studies to finance, and what results to publish and put a status of official politics to what has been published.
