Persons who wish to lose weight quickly typically choose these diets. Healthcare professionals tend to prescribe these diets less frequently. Some people might not be able to safely lose weight quickly on their own.
These diets should only be followed temporarily and are not advised for use over an extended length of time.
Those who lose weight slowly with moderate dietary adjustments and exercise are considerably less likely to gain it back than those who lose weight quickly.
The body experiences more stress when losing weight, and this causes a higher hormonal reaction. One of the reasons why weight reduction slows down over time and why weight gain occurs is the hormonal reaction.
Explain the Pre-op diet
Your bariatric surgeon could suggest changing your diet even before you have weight reduction surgery to get your body ready for the procedure.
This particular pre-operative diet can help shrink your liver, reduce abdominal fat, and increase the likelihood that your operation will be conducted laparoscopically by making it easier and safer for your surgeon to execute.
Losing weight before surgery will also speed up your weight reduction, aid in recuperation, and ease the adjustment to your post-operative diet.
Each patient’s pre-op diet should be followed for a different amount of time. Your bariatric surgeon will provide you with pre-surgical diet advice based on your circumstances and how much weight you need to drop before surgery.
For patients with gastric bands, the pre-op diet may begin two to three weeks before surgery, although it may begin sooner for those with more complicated procedures like a gastric sleeve or gastric bypass.
You may anticipate that the diet you follow before surgery to lose weight will be high in protein but low in calories, lipids, and carbohydrates, particularly those made from refined sugars and saturated fat.
The pre-surgery diet typically contains between 70 and 120 grams of protein per day and 800 to 1200 calories daily. Additionally, taking vitamin supplements is advised to give your body the nutrition it needs for healing and good health.
What is the purpose of a pre-surgery diet?
Your surgeon may advise a pre-surgery diet for a number of reasons, but one of the most frequent ones is to shrink the liver.
Most individuals with fatty liver disease also have increased BMIs. This is the time when extra fat cells build up on the liver, which is close to the stomach.
To reduce operating time and injury risk and shrink the liver, surgeons advise patients to lose weight before surgery.
Most hospitals begin a strict diet two weeks before surgery. Other facilities that place a greater emphasis on lifestyle decisions immediately advise changing dietary habits.
Patients in bariatric surgery facilities are frequently placed on an all-liquid diet to encourage quick weight loss. Other facilities, however, concentrate on behaviour modification to encourage good eating habits and long-term weight loss.
The diet may also include protein supplements, typically in the form of shakes or powders, as well as a reduction in all fats, sugary foods and beverages, and high-carbohydrate items like white bread and pasta.
It provides a remedy for individuals who have struggled for a while to lose weight in a healthy manner and have a body mass index of 40 or more.
1. Very Low-Calorie Diet (VLCD):
You can consume as low as 800 calories per day while using a VLCD and lose up to 1.5 to 2 kg each week. 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 people who are obese and need to lose weight for medical reasons are advised to use a VLCD.
Before having weight-loss surgery, these diets are frequently used. Following the advice of their doctor, people should follow these diets.
2. 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 LCD rather than a VLCD. These diets should also be followed in accordance with the advice of their supplier.
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.
3. Time-restricted eating:
These days, more people are adopting this diet. Eating that is time-restricted restricts how many hours a person can eat each day.
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.
4. Intermittent fasting:
A form of calorie restriction is fasting. Recently, it has gained popularity. People who are obese and those with diabetes have shown some benefits from fasting.
There are numerous variations in fasting schedules. The 5:2 system is among the most common. This calls for two days of fasting every week, or a VLCD, and five days of eating normally.
5. Fad diets:
In order to lose weight quickly, several fad diets also restrict calories.
These diets can occasionally be unsafe. These diets don’t produce long-term weight loss, and if you quit following them, you run the risk of putting on weight once more.
A high-calorie, low-fat diet that encourages the eating of rice, beans, potatoes, and other starches is an example of a fad diet.
6. Role of exercise:
Fast weight reduction or rapid weight loss focuses more on calorie restriction than exercise. You should see your doctor about the best forms of exercise to combine with a low-calorie diet for rapid weight loss.
7. Health benefits:
Rapid weight loss diets are typically used by persons who are obese and have health issues. Losing a lot of weight quickly can help these people:
- High cholesterol
- High blood pressure
8. Possible health concerns:
Only one of these diets should be followed, and only after consulting your physician. You can lose bone density, hydration, and muscle as a result.
Rapid weight loss increases the likelihood of rapid weight gain. Other health issues may result from this. Children, pregnant women, and older adults should not follow a quick weight loss diet unless a healthcare professional advises them to.
Before beginning this diet plan or any other diet for weight loss, it is a good idea to speak with your healthcare professional if you have a health issue.
Things to consider on the Pre-op diets
- Protein is a key component of your pre-and post-operative bariatric diet because it helps your body function normally, heal wounds more quickly, retain muscle mass, and prevent unneeded hair loss.
- Unlike fat and carbohydrates, protein cannot be stored by the body and must be ingested in enough amounts daily. Following weight loss surgery, protein will be the most important dietary component both during recovery and for the rest of your life.
- Generally speaking, 10–35% of your daily calories should come from protein. For males and women, respectively, the Recommended Dietary Allowances (RDA) for protein per day are 56 grams and 46 grams.
- Your surgeon will provide detailed instructions on how much protein you should consume each day. Your surgeon will provide detailed instructions on how much protein you should consume each day. Your daily requirements for protein depend on your age and BMI.
- You will utilize protein supplements as necessary to meet your daily protein goal. Your body will need time to recover from bariatric weight loss surgery, whether you had an adjustable gastric band installed or underwent a more involved procedure like a gastric sleeve or gastric bypass.
