The doctors revealed the pros and cons of four popular modes of consumption popularized on Instagram.
According to doctors at the University of Southern California (USC), although eating like a caveman can limit people's appetite, the lack of carbohydrates can cause constipation, while the lack of carbohydrates can cause constipation. Protein focus can lead to excessive consumption of saturated fats.
Although the keto diet, which includes such celebrities as Gwyneth Paltrow and Halle Berry, forces the body to burn fat, it also increases the risk of reduced bowel movements, extreme hunger and even kidney stones, scientists said. .
While juices clean, which Blake Lively is known to be a fan, seriously limit caloric intake, they can cause people to keep their weight if they cut too long for solid foods because their bodies enter " famine mode ".
Raw diets, backed by actress Megan Fox, guarantee people a diet rich in fiber and vitamins, but can leave them panicking and threatened with food poisoning.
Scientists conclude that the most effective diets are those that people can follow in the long run.
Gwyneth Paltrow is said to be a fan of the keto diet that forces the body to burn fat
Yet the diet, also followed by Halle Berry, can cause extreme hunger
ARE YOUNG REGIMENTS GOOD FOR THE HEART?
Following a "fashionable" fast for a week can damage the heart, according to a study suggested in February 2018.
Obese people who suddenly reduce their caloric intake to only 600 to 800 units a day see their fat content increase by 44%, according to one test.
Although these dieters lose an average of 6% of their total body fat in just seven days, this fat is released into the bloodstream and absorbed by the heart, the researchers explained.
Although this excess heart fat is balanced at the eighth week of the diet, it could be out of breath for people with heart problems and with an irregular rhythm, added scientists at Oxford University.
The researchers analyzed 21 obese volunteers aged 52 years on average and a BMI of 37 kg / square meter.
Participants in the study followed a very low calorie diet every day for eight weeks.
MRI scans were performed at the beginning and end of the survey, as well as after the first week.
High protein, low carbohydrate diets like paleo or Atkins help reduce people's appetite and prevent hunger.
The reduction of carbohydrates causes the body to burn fat as fuel, while the elimination of sugars also improves insulin levels.
Dr. Michael Goran, co-director of the Institute for Research on Diabetes and Obesity at the USC's Keck School of Medicine, said, "The more you can reduce carbohydrates, the better you'll get." This is particularly sugars and highly processed foods, which tend to be higher in carbohydrates.
"A high carbohydrate diet generates a lot of glucose, which means you have to produce more insulin to eliminate it.
"It stresses your body and, over time, can contribute to cardiovascular disease or a risk of diabetes."
The complete elimination of carbohydrates means that we are lacking nutritious foods like fruits and vegetables.
A large amount of protein without fiber can also cause constipation, while people can feel tired and irritable when their body turns into fat to burn energy.
The focus on meat can also cause people to eat too much saturated fat.
The keto diet is a variant of the Atkins that focuses on the high content of fats, moderate protein and extremely low carbohydrates.
Keto diets lower insulin levels and move the body into fat burning mode, while also benefiting people's cholesterol levels.
The drastic reduction in carbohydrate intake increases the risk of constipation.
Keto diets also leave people hungry for the first few weeks.
Claudia Del Vecchio, a nutrition educator at USC's Keck Hospital, explains: "It's because you lose serotonin and the energy you normally get from carbohydrates.
"Many people also experience sugar weaning and feel nervous. But after a few weeks, they feel better.
People with kidney problems should avoid keto diets because of the diet likely to affect their urine production and increase the risk of kidney stones.
Making juice cleans, like Blake Lively, can prevent people from losing weight if this is done in the long run
Megan Fox is a follower of raw diets, which increases the risk of food poisoning in people.
WHAT IS THE BEST TIME OF THE DAY TO EAT CARBOHYDRATES?
Dr. Michael Mosley, a television doctor, suggested the best time of day to eat carbohydrates.
He discovered that eating pasta and bread at dinner was better for people than for toast in the morning.
Experts previously thought that carbohydrates should be largely consumed early in the day because the body has more time to burn the glucose it releases.
Otherwise, the release of insulin will bring the blood sugar level back to normal, which will be done by storing the excess sugar contained in carbohydrates in the form of fat, thus causing people to take up weight.
Yet, the new study, aired on Trust Me I 'my Doctor of the BBC, revealed that eating carbohydrates at night caused blood sugar rises less spectacular than carbohydrate loading at breakfast, provided that the rest of the food intake of the day was too rich in starch.
Dr. Mosley advises people to align with their dietary habits on carbohydrates and avoid being abused at every meal.
He has conducted research with the University of Surrey, asking healthy volunteers to consume the majority of their daily carbohydrate intake in the morning or evening.
All participants in the study ate the same amount of carbohydrate every day, including bread, pasta and vegetables.
For the first five days, they ate most of these foods at breakfast, followed by five days of normal diet before finally switching to a low carbohydrate breakfast, a high carbohydrate meal for the last five days.
The researchers analyzed participants' blood sugar levels throughout the study.
Composed of fruit and vegetable juices, this liquid diet reduces calories and imitates fasting, which causes the body to burn fat for energy.
Dr. Goran said, "By pausing the processes involved in digesting foods, you are reducing factors such as stress hormones and insulin-like growth factors, which can reduce your risk of cancer." . "
The juice cleans also reduce people's insulin levels.
Most people will be hungry. They may also experience a drop in blood sugar if they drink a lot of fruit juice, which does not contain a lot of fiber.
In addition, if people clean their juices for more than a few days, their bodies may think that they are starving and stopping burning calories.
Such plans usually include uncooked vegetables, fruits, nuts and sprouted cereals.
Some plans also allow unpasteurized dairy products, eggs and raw fish.
Those who eat raw diets will get a lot of fiber, vitamins and minerals after eating whole foods.
Due to the fact that these diets eat a lot of fiber, people may feel faint, swollen or have diarrhea.
People also increase the risk of food poisoning caused by the fact that toxins are not eliminated during cooking, as well as by certain nutrients requiring heat absorption.
Dr. Del Vecchio said, "For example, lycopene, an antioxidant found in tomatoes, is more bioavailable when tomatoes are heated than when they are eaten raw."
