rapid weight loss

Rapid weight loss happens when you drop more than 2 pounds (1 kg) every week for several weeks. You must consume extremely few calories in order to lose weight quickly.

Weight loss is bound to occur in every phase of life, both in humans and animals, as a part of growth and transition experience from one form of body mass reduction or the other. Most of the time, a change in body weight can be either due to stress, childbirth, a depreciating health condition, or a change in the environment.

When you lose a lot of weight quickly, your body is deprived of the vital nutrients it needs for proper function. Additionally, a lack of essential minerals such as vitamin D or calcium may increase your chance of contracting certain illnesses or make you more vulnerable to damage.

We are aware that being obese is bad for our health. For good reason, healthy lifestyle programmes have consistently emphasized the need to maintain a healthy weight. However, there are numerous approaches to achieving weight loss; it is not a one-flavour dish. As a result, more is rarely always better. When it comes to weight loss, going too far too quickly can pose a real health danger.

Extreme weight loss is undesirable, and it can actually be quite harmful to your body. Your body will not be able to keep up in such conditions, and symptoms will undoubtedly become apparent. On the surface, some of these effects, such as slight hair loss or feeling cold more often, may appear to be harmless. However, other consequences can have long-term negative repercussions on your physical and mental health.

What Is Rapid Weight Loss?

Rapid weight loss is the abrupt lowering of bodily mass, either intentionally or unintentionally. When a person loses more than 2 pounds (1 kg) of body mass per week, they are said to be losing weight rapidly. Since it typically takes 3500 calories to make one pound, eliminating 7000 calories in a week presents the body with a deficit that it must address.

It can also be worrisome when all attempts to increase calories fail and body mass loss continues. This could be a good time to see a doctor or consider one’s mental state because an unstable mind can affect the food metabolism and general physical appearance.

Some Of The Severe Consequences Of Rapid Weight Loss.

Here are some of the adverse effects to consider when embarking on rapid weight loss programme.

Electrolyte Imbalance

Numerous biological processes are controlled by materials found in nature or naturally occurring elements. Any disparity or imbalance in their proportions has the potential to be hazardous and may result in disorders like seizures and arrhythmia (irregular heartbeats). Particularly important for cellular health and function are electrolytes. If the latter were to fail, the body as a whole would not take long to follow.

Nutritional Deficiency

Your body is deprived of the vital nutrients it needs for proper function when you lose a lot of weight quickly. Additionally, a lack of essential minerals like vitamin D or calcium might increase your chance of contracting certain illnesses or make you more vulnerable to injury. Anaemia, which is characterized by sensations of weakness and fainting spells and can happen when you do not get enough iron, is one such example of an illness connected to nutritional deficiencies.


Indigestion and excruciating pain are both experienced when gallstones form. They develop when the gallbladder’s digestive secretions are held in due to a lack of food to digest. Once inside the gallbladder, these liquids solidify and may even plug the opening, resulting in indigestion and more pain and suffering. As the body metabolizes fat during rapid weight loss, it causes the liver to secrete extra cholesterol into bile, which can cause gallstones.

Sharp Reduction In Energy Levels

Your energy levels will undoubtedly suffer if you consume insufficient calories or burn through too many calories. In addition to physically feeling exhausted, your cognitive abilities and productivity may suffer. Your mood may also be impacted; extreme weight loss is frequently accompanied by constant feeling of irritation.

Loss Of Muscle Mass

Not only do you lose muscle when you lose weight, but you lose also fat. The ratio of fat to muscle is further thrown off by a loss in muscle mass, which frequently coincides with a slower metabolism. Weaker muscles make daily chores like lifting heavy goods or climbing stairs more difficult. Even if the final weight on the scale looks better, your quality of life might not be as good.

Advantages Of Rapid Weight Loss.

Although there are some adverse consequences associated with rapid weight loss which you need to put into consideration. There are ways it could also be beneficial to our body.

Rapid weight loss regimens have a long history of negative connotations. People frequently claim that while they produce short-term success, they set them up for long-term failure. They claim the person will gain back all of their lost weight and then some.

But it’s becoming more and more obvious that this is not the case as more and more study is conducted.

A 12-week quick weight loss programme or a 36-week moderate weight loss programme had 204 participants in a research that was published in The Lancet Diabetes and Endocrinology journal. The findings indicated that while the long-term weight reduction was comparable to a gradual weight loss diet, the quick weight loss group had better short-term effects (more weight loss).

Rapid weight loss is achieved by a very low calorie diet, usually using shakes, formulas and/or dietitian-approved meals to ensure nutritional adequacy, providing high protein and a balance of vitamins and minerals to help you lose weight while staying well nourished.

Consuming low calories (approximately 1,000-1,600 calories per day) promotes rapid fat loss, resulting in improvements to blood sugar levels, blood pressure and cholesterol. Furthermore, it is very motivating for individuals to see results of their hard work thereby encouraging them to maintain a healthy eating habit.

Individuals who follow a rapid weight loss diet often see 10-25% weight reduction during the first 3-6 months and maintain 5% or greater weight loss after four years. So, if you are thinking about the optimal rate of weight loss for you, consider this: those who follow a rapid weight loss diet achieve greater weight loss in the short-term AND long-term maintenance, and they are no more susceptible to weight regain than other dieters.

So, if you are pondering your ideal pace of weight reduction, keep in mind that people who adhere to a rapid weight loss diet do so in both the short and long term, and they are not more likely to gain the weight back than other dieters.

Diet For Rapid Weight Loss

A rapid weight loss diet is one in which, over a period of weeks, you lose more than 2 pounds (1 kilogramme) per week. You must consume extremely few calories in order to lose weight thus quickly.

How does rapid weight loss diet work?

Obese persons who wish to lose weight quickly typically choose these diets. Health care professionals tend to prescribe these diets less frequently. A provider should keep a close eye on anyone following one of these diets. Some people might not be able to safely lose weight quickly on their own.

These diets should typically not be used for longer than a few weeks and should only be used temporarily.

People who lose weight quickly are significantly more likely to gain it back than those who lose weight gradually through more moderate dietary adjustments and exercise. The body experiences more stress when losing weight, and this causes a higher hormonal reaction. One of the reasons weight reduction slows down over time—as well as why weight gain happens when the diet is abandoned or relaxed—is the hormonal reaction.

The various diets for quick weight loss are detailed below.

Very Low-Calorie Diet (VLCD)

You can lose up to 3 to 5 pounds (1.5 to 2 kg) every week with a Very Low-Calorie Diet (VLCD), which allows you to consume as low as 800 calories per day. Meal replacements, such as formulae, soups, shakes, and bars, are typically used in place of regular meals in VLCDs. This makes it possible for you to acquire all the nutrients you require each day.

Only persons with obesity who need to lose weight for medical reasons are advised to do a VLCD. Before having weight-loss surgery, these diets are frequently used. Only utilize a VLCD with your health provider’s assistance. The majority of experts advise against using a VLCD for longer than 12 weeks.

Low-Calorie Diet (LCD)

For women, these diets typically allow 1,000–1,200 calories per day, and for men, 1,200–1,600 calories per day. Most people who wish to lose weight quickly should opt for an Low-Calorie Diet (LCD) rather than a VLCD. But a health provider should still be watching over you. With an LCD, you won’t lose weight as quickly, but a VLCD can help you lose the same amount of weight.

An LCD might consume both conventional meals and meal replacements. It is easier to follow because of this than a VLCD.

Intermittent Fasting

A traditional method of calorie restriction is fasting. Recently, it has grown in popularity. This is partially due to studies on both humans and animals showing advantages of fasting for those who have diabetes and obesity. There are numerous fasting schedules available, and it is unknown which may be the most effective. The 5:2 system is among the most common. This calls for two days of fasting or VLCD per week and five days of eating normally. Fasting-based diets can help you lose weight quickly.

Time-Restricted Eating

This eating plan is gaining popularity. It is frequently contrasted with fasting, however the two methods differ slightly. Your daily eating window is capped if you practice time-restricted eating. The 16:8 ratio is a common tactic. You must adhere to this regimen by eating all of your meals inside an 8-hour window, such as from 10 am to 6 pm. You are unable to eat anything else at that period. Studies have shown that this strategy can result in quick weight loss, although it is unclear at this point if the weight loss is long-lasting.

Fad Diets

In order to lose weight quickly, several fad diets also severely restrict calories. These diets can occasionally be dangerous. These diets typically don’t last long enough to result in long-term weight loss. If you resume your former eating patterns after stopping the diet, you run the risk of putting the weight back on. The safest diet for the majority of people is one that involves weekly weight loss of 225 grammes to 500 grammes, or 1/2 pound to 1 pound.
