It is possible with a reservation. If you are losing weight and do not want to feel hungry. then protein shakes, immediately add bran to them. To fill the stomach with every meal, fill it with vegetables. + drink fish oil in any form. even in spoons, even in capsules. everything is super tested. I have the opportunity to eat fully only 1 time at work at lunchtime. In the morning, porridge + fast-digesting proteins from the blood. On the way in the car and during the working day, mixed proteins + vegetables (cucumbers, lettuce, tomatoes, peppers, etc.). Casein protein at night.

No, you can't. A protein shake consists almost entirely of protein, may contain a small amount of carbohydrates. But the body needs not only them.

For example, it is very difficult to do without unsaturated fatty acids like omega-3. They slow down aging, have a positive effect on the condition of blood vessels, skin, brain, heart, ligaments and joints. Also, acids give the body energy, improve muscle recovery after exercise, reduce the risk of stroke and heart attack (which is also important with intense training).

In addition, the body needs various vitamins and minerals to maintain immunity and in general all organs, bones, joints in a healthy state. Yes, many manufacturers add vitamins and minerals to protein, but, as a rule, it does not contain absolutely all the substances that we need.

That is, Ie. Protein shakes are a good protein supplement for your regular diet, but should not be used as a substitute for regular meals.

A good nutrition is not only protein, but also fats, carbohydrates (fiber), vitamins, minerals and other substances.

A couple of days purely on cocktails can be lived without any problems, as long as there are certain stocks of other substances, then at least avitominosis and a significant decrease in the rate of metabolism will begin.

Although cases of complete starvation are known for several months, and at the same time people remained alive. And many bodybuilders consume only protein for several days / weeks before performing. But this is certainly not a healthy lifestyle.

No, you can't. I would say that it is absolutely impossible. You can replace 1 meal, especially if you eat 4-6 times a day, and not the standard 3.

Why not? In short:

  • Protein shakes are different. Most often, they DO NOT contain anything other than pure protein (up to 99% of the mass of the product), and carbohydrates and possibly even a small amount of fat will be in the gainer. Eating only proteins is nonsense, you ruin your body, because the main source of energy is carbohydrates, then fats, and it is not very profitable to get energy from proteins from the point of view of chemical reactions taking place in your body - this is, first of all, a building material for your muscles, and indeed the whole organism as a whole, his cells. Your whole metabolism will go downhill, so you can finish badly before resuscitation.

  • Protein shakes may not contain other nutrients - vitamins, minerals, fiber, etc. etc. Their importance for the body is no less than BJU. Where they are added, you still need to figure out the quality of this raw material, its efficiency of assimilation in your body. In addition, there are many fakes in the sports nutrition environment, where they sell you some kind of chaff powder under the guise of a super-useful cocktail. I once found a weevil in a package of a gainer, this is about the quality of raw materials and the rules for its storage))

  • Even if it’s just stupid to take all the known useful substances for the human body to mix into a homogeneous mass (already a bad idea), and divide into 3 equal portions according to the recommendations for the daily intake of nutrients, it’s all the same delirium of a gray mare on a moonlit night. Firstly, useful substances have different chemical and physical properties, for example, some dissolve in water, others in fats, some are heat-resistant, others can be destroyed at temperatures below the boiling point of water, and there is also synergism-antagonism - this is when substances improve or worsen assimilability of each other. In the second case, they cannot be mixed with each other, or they can, but in a certain proportion. For example:

The ratio of phosphorus to protein in food should be 1:40 - this ratio should be considered as mandatory.

A diet rich in protein contains 10 times more phosphorus than calcium, while its intake should not exceed 2 times!

For normal absorption of calcium, it is necessary that it be in certain proportions with magnesium and phosphorus:

with magnesium (Mg)

* no more than 1: 0.6
with phosphorus (P)

* for adults - no more than 1: 1.5
* for children - 1.25: 1
* for infants - 1.5: 1

And such proportions and recommendations are dark, and you can't fit them all into one whole, something will always interfere with something. You cannot grasp the immensity, which means that the lion's share of your healthy cocktail from everything at once will remain absolutely useless for your body, if it does not lead to a violation at allmetabolism.

Basically your question relates to whether it is possible to eat Soylent. Yes, despite what I wrote above, such a cocktail exists, but this is a purely commercial move. There is no serious scientific evidence that its use is even safe for health, nor that it is useful, and it can replace all food entirely.

  • And finally, I will say that millions of years of evolution of our digestive system They did not prepare us at all to eat thin cocktails = possible diarrhea / constipation, nausea, headaches, colic, etc. and so on, which then will result in much more sad consequences for the body. Your mouth will also suffer, because refusal of solid food will lead to the fact that there will be no stimulation of the gums, blood flow in the mouth, which will deteriorate the condition of the teeth. Dentists already say that we now eat too much of everything soft and liquid.
