Protein diet

Protein diet


Today I would like to talk to you about protein diets  and how these diets can affect our way of life and affect our health.

We assume that low calorie, high protein diets , without a good balance, will cause you to lose weight but in a very unhealthy way.

Now, if you’re thinking, “This can’t be true, some of these diets were created by doctors and there are books about protein-rich weight loss diets  and protein-rich diet products in stores!”

And do you really believe that this can be a solution and an answer to our doubts?

The first step in taking care of your health is realizing that the doctors who promote high protein diets are people and some people just want to make money and don’t care about your health.

A sad fact of life, I realize, but it is a fact nonetheless.

And the shops?

Stores need to do business.

As long as these things don’t kill people instantly, and as long as there is demand to buy, they will be available for sale.

If these products and diet plans do harm slowly, over a long period of time, who cares.

I want it to be clear in your head.

I hope that you too clarify what I am about to tell you.

How does it work

Protein diet: how it works
Weight loss through a high protein diet is a quick fix.

But there are safe and healthy ways to lose weight without negatively impacting your health.

To understand why high protein diets ( dukan diet pdf ) are bad for our health, it is necessary to understand how the body works.

Carbohydrates are converted by the body into glucose , which is the optimal fuel for the organs that make the body alive (particularly the brain).

Our cells use this fuel but once they have had enough they take the extra glucose stores and convert it, thanks to the liver, into glycogen which is stored in the muscles as an energy reserve.

When there is no more space for glycogen storage, the excess is converted into triglycerides which are diffused in the blood and taken up by the fat cells, and then stored as fat.

One of the reasons that make us lose weight in a diet balanced between proteins (in greater number) and carbohydrates (in less number) is the low presence of glucose in carbohydrates as a source of energy to burn.

In the absence or in the absence of glucose, excess fat becomes fuel for our metabolism to burn and so we lose weight.

Fats (as well as proteins) are not as efficient at fueling as carbohydrates, and they do not burn clean energy like carbohydrate glucose.

Yes, you lose weight, but to the detriment of your health.

Here are some of the things that happen with a high protein diet.

But let’s go in order and see a typical food program.

Protein Diet: program

Protein diet: program

Here are the foods recommended in a protein diet .

As you can see there is a nice choice between meat, fish, eggs and even plant foods rich in proteins, for vegans, such as tofu and seitan.

By expertly mixing these ingredients we get the weight loss result.


  • Red meat
  • poultry and white meat
  • fish and shellfish
  • low-fat dairy products such as light spreadable cheese and lean ricotta
  • skimmed milk
  • egg
  • dried fruit
  • lean meats such as bresaola, chicken ham and turkey
  • tofu
  • seitan
  • light feta cheese


Protein diet: results

The results, on an uncontrolled diet, are terrible.

Let’s see specifically.

The protein-rich foods recommended for these diets are foods of animal origin, for the most part, as you may have noticed.

These foods must be cooked.

Cooking destroys nutrients (one of the main reasons why diets don’t work in the first place is that the body is continually hungry, not for energy fuel but for nutrients, which are lacking in cooked food and this keeps intact, moreover, the desire for food).

Animal proteins contribute to heart disease, immune dysfunction, colon and ovarian cancer, prostate enlargement, diabetes and a number of less serious conditions.

Animal foods are also rich in arachidonic acid , a dangerous fat that causes the release of a hormone that produces inflammatory conditions that can lead to arthritis, psoriasis, and Crohn’s disease.

Symptoms of multiple sclerosis, PMS, and some autoimmune diseases can also intensify.

Furthermore, animal proteins contain two strong amino acids, methionine and cysteine , which must be neutralized to keep the body’s blood pH at a normal level (if the blood cannot carry oxygen to the cells, there can be no life).

The best neutralizing agent the body has at its disposal is calcium (from the bones). The more animal protein you eat, the more calcium your bones take and the higher your risk of osteoporosis (and guess what: milk contains animal protein!).

Additionally, cysteine ​​is the precursor of homocysteine , which causes cholesterol and occludes artery walls leading to coronary heart disease.

Your cholesterol level is not a good indicator of cardiovascular health as is your homocysteine ​​level.

It is not the cholesterol in the blood that is bad, it is the cholesterol stuck in the artery walls that is dangerous.

Many heart attack victims have “normal” serum cholesterol levels.

On a high-protein diet , weight loss can be the result of muscle loss.

Once no more glucose is being supplied, the body feeds on the glycogen in the muscles.

When glycogen is released from muscle tissue, water is also released. Weight loss therefore results from the breakdown of muscle tissues to get to glycogen and the accompanying release of water.

The more water you lose, the more weight you lose.

The downside is dehydration and muscle loss.

Frequent questions

I try to answer with a reasoning to the most frequently asked questions I encountered in my information path on the protein diet.

By losing lean muscle mass, your basal metabolic rate is lowered (BMR is the amount of calories you burn in a 24-hour rest period).

The long-term effect of a lower BMR is that you will have to try to eat less or you will start gaining weight.

Obviously, as you lose muscle mass, you lose strength.

Not so obvious is the emphasis placed on the immune system trying to detoxify the body of everything that the metabolism takes and discharges from proteins.

We are talking about heavy, almost poisonous, discharges that are usually contained in substandard low-carb foods, which can cause constipation and intensify dehydration, a causative factor in the disease.

And as if all of this weren’t bad enough, animal foods contain substances that are certainly not good for our health: growth hormones, antibiotics, pesticides, just to name a few.

So why think carbohydrates are bad for you?

Basically there are good carbohydrates (simple carbohydrates like those in fruits and vegetables ) and bad carbohydrates (complex carbohydrates like in white flour and processed wheat).

Foods with good carbohydrates have soluble fiber in them.

Fiber slows the absorption of sugar into the cells, which results in fewer triglycerides being produced and stored as fat.

And then, foods rich in fiber, like fruits and vegetables, have natural sugars, as opposed to processed foods, refined sugars, which wreak havoc on your body’s blood sugar regulation system and can be stored as fat. mind that a glass of apple juice, which lacks fiber, will have a different effect on sugar absorption, because it is not apple, it has no fiber).

Animal products have zero fiber and since soluble fiber helps your life animal protein certainly doesn’t help.

For nothing!

Do you have to abound with fruit and vegetables?

Protein diet: do you have to abound with fruit and vegetables?

Fruits and vegetables are also foods with a higher water content than foods of animal origin.

The more water in the food you are going to eat, the better.

People who eat large amounts of fruit and vegetables, and little or no animal-based foods, are usually leaner and healthier.

So why isn’t a fruit and vegetable-only diet not popular as a diet?

People are addicted to food of animal origin.

And those who create diet plans know this.

They also know that if they give people what they want they will be successful.

They are not interested in giving people what is good for people.

And that’s a mistake, because giving people a varied diet, with lots of different foods and a lot of fruit and vegetables is what I consider to be a healthy diet plan, with good stuff to eat.

So a very strange fact we have to discuss is the complete inability of those who find themselves advertising a protein diet to put foods rich in fiber in their diets.

We could consider this a monopolization of a fashion and not a real attention towards what hurts less, which really improves our health.

Should we count calories?

The calorie counting problem is a fictional problem: 1000 calories of donuts are sure to hurt more than 1000 calories of watermelon.

This is another of my facts.

So when do we need protein the most?

Answer: as children.

It is during the first few years of life that most growth occurs.

Growth is highly protein dependent.

If your diet was exclusively based on breast milk (which is all protein) your ingested proteins exceeded two hundred percent!

So why do you need more protein when you are an adult?


Personally, I have had little to do with animal protein in the past 20 years and I feel better than ever!

Where can I find my proteins?

 Protein Diet: Where Can I Find My Protein?

About half of my daily requirement is met by my body’s recycling of damaged proteins (the body breaks down non-functional proteins into their constituent amino acids, discards the damaged ones and feeds on what’s good).

The rest of my protein needs are met with fruits and vegetables (yes, they contain protein).


I don’t want to sound too abrupt, or too attentive to what we eat, but a minimum of extra attention to our body is the minimum.

The real problem we should discuss is certainly not the protein itself, a fundamental value for those who want to grow and do it well, but the excess of them.

The real absolute drama of the last 30 years is in fact that of the excess of protein that is present in our diets.

We know, indeed we have learned the hard way, that eating too much meat is bad for you.

Inserting a different type of meat into a diet every day is certainly not good for our body and not good for us.

We should focus on looking for a diet that can be as varied as possible, which has enough animal proteins in it but, above all, fruit and vegetables, which also have a protein base in them but which are rich in fiber.

Fiber has a fundamental characteristic, it manages to slow down our metabolism in order to make us feel full for longer and, above all, it regulates the entire intestinal tract making it more regular.

Protein, protein diets in general, must be considered fundamental in the years of growth and then a nutrient to turn to certainly not in a daily diet.

We need moderation and balance, always.

Without letting ourselves be conditioned by fashions and by what are the words of people who make the health of others a business with which to create mountains of money.

Have you ever tried the protein diet ?

If so, what have your results been and how long have you been pursuing it?
