Does Donating Plasma Burn Calories?
Donating plasma has lately become a much-talked-about practice around the globe due to various health benefits. This also includes weight loss resulting from loss of calories during donation.
It is being argued that the body loses calories due to the loss of a lot of fluid and then the body uses energy to regain the lost plasma, hence resulting in burning some extra calories.
It is important that you do not confuse plasma donation with blood donation. Blood donation results in more caloric loss as compared to the former. However, donating blood frequently can have undesirable side effects.
Plasma on the other hand is 95% water and donating plasma can cause temporary weakness. However, it does have scientifically backed proof that it helps lose calories. And the exact amount depends upon how much plasma you donate and how often.

Can Donating Plasma Help Lose Weight?
The simplest answer to this question is, yes! Donating plasma means losing some calories because the body burns energy to replenish the lost plasma. In doing so, the body loses some calories and lost calories means lost weight especially when this is done on a regular basis.
However, the thing to be noted here is that this weight loss can not be permanent until it is accompanied by a workout and a balanced diet. The weight lost as a result of plasma donation is caused by fluid loss, not fat loss. So, it will be temporary weight loss if it is not followed by exercise.
Does Donating Plasma Burn Calories?
Yes, it does burn calories because once the plasma is lost due to donation, the body tries to replenish it and in doing so it burns calories. This is the reason some people may feel temporary weakness and a feeling of tiredness or laziness after a donation session.
The number of calories lost depends on the amount of blood drawn from the body and this amount in turn is dependent on your body weight. For a clear idea about how much blood a health practitioner would draw from your body and how many calories will be burnt to replenish this loss, refer to the table below:
Weight Range | Plasma Drawn | Calories Lost |
110-149 lbs | 690ml | 483.69 |
150-175lbs | 825ml | 578.33 |
175lbs- above | 880ml | 616.88 |
In short, number of calories lost is influenced by the amount of blood drawn from your body. And the amount of blood that will be drawn depends on which weight range you fall into from the above-mentioned three ranges.
However, plasma donation as compared to blood donation burns a lesser number of calories. On the other hand, the side effects associated with donating plasma regularly are mild as compared to donating blood on a regular basis.

After donating plasma, you might feel a dip in energy level. However, this doesn’t mean you need to eat a lot after donation. However, health practitioners advise eating meals after donation which are high in protein. Similarly, regular donors should eat a diet high in iron.
Since plasma is mostly water, losing plasma means losing body fluid along with salts. In order to avoid dehydration, you need to replenish the body for lost fluid and salts. In such cases, a protein smoothie will not only replenish the lost protein but also be effective against the risk of dehydration. Similarly, taking electrolytes and juices right after donation is also advisable.

Besides, the body needs some time to start the replenishment process. Hence, you should avoid rigorous workouts after donation and focus on getting a diet rich in protein and fluids.
Besides, it is even advisable to avoid a rigorous workout right before donation especially if you are going to donate for the first time. Instead get some low fat, healthy diet to prepare your body for plasma donation.
