Don’t Diet To Lose Weight If You’re Not Obese…Harvard Study Hints

A major study finds that a dramatic diet to lose weight when you’re not obese can harm your health years later.

Really thin people who lost 10 pounds (4.5 kg) were more likely to develop type 2 diabetes a decade later than their peers who didn’t follow an extreme diet.

They were also more likely to pile on the pounds down the streak, according to research from Harvard University.

The scientists said their results were “surprising.”

But they believe that thin people who have undergone significant weight loss have higher levels of hunger hormones, which makes them more likely to crave fast food, and can gain fat more easily.

Many skinny people try to lose fat in the hopes of gaining Instagram-style abs or a more toned physique.

But the team at Harvard University now warns that exciting weight loss diets should only be used by those who “medically need them.”

The results also showed that thin people who lost weight with a fad diet or commercial weight loss program were more likely to develop fat later in life.

About 40 percent of American adults are overweight, but a study The researchers noted that up to half of women and 20 percent of thin men think they also fall into this category.

The graph above shows weight change after ten years in people who were considered lean (blue bars) or obese (red bars) at the start of the study and experienced an extreme weight loss of 9.9 pounds (4.5 kg). It is broken down into the method used to lose weight (the left column gives the labels), and the amount of weight lost or re-gained over ten years compared to people in the same group who did not attempt significant weight loss. All of those who experienced significant weight loss in the lean group gained more weight than their peers, up to 17 pounds (7.7 kg), the study says.

Many skinny people try to reduce their weight in order to get a toned body

Many skinny people are trying to lose weight in order to have a toned ‘Instagram-ready’ body. But scientists have warned that this is harmful to their health

In what is believed to be the first study of its kind, experts looked at data from 200,000 healthy Americans collected between 1988 and 2017.

Nine out of ten participants were female.

They were divided by body mass index (BMI) into those who were skinny—with a healthy range or underweight—overweight, or obese.

A healthy BMI means that a person has a good body fat-to-height ratio that does not put them at risk of developing obesity-related diseases such as high blood pressure.

How do you calculate your BMI – and what does it mean

Body mass index (BMI) is a measure of body fat based on your weight in relation to your height.

Standard formula:

  • BMI = (weight in pounds / (height in inches x height in inches)) x 703

Metric formula:

  • BMI = (weight in kilograms / (height in meters x height in metres))

Measurements:

  • Under 18.5: weight loss
  • 18.5 – 24.9: healthy
  • 25 – 29.9: overweight
  • 30 – 39.9: Fat
  • 40+: excessive obesity

Each group was then divided into two groups—those who lost 9.9 lb (or 4.5 kg, kg)—in the four-year time frame and those who did not.

Weight Watchers were also asked to say how they lost weight and were divided into seven groups – a low-calorie diet; Playing sports; Low-calorie diet plus exercise; fasting; commercial weight loss program; Diet pills and a combination of fasting, diet, and diet pills (FCP).

Then the scientists followed the participants’ medical records for an average of 10 more years.

Among thin people, those who followed an extreme diet gained between 4.4 and 17 pounds (2 to 7.7 kg) more than their peers.

But among the obese people, those who performed four of the programs — a reduced-calorie diet, exercise, a reduced-calorie diet, exercise and fasting — stopped off at 3.5 to 1.3 pounds (1.2 to 0.5 kg) more than those who were obese. peers.

In the other three — a commercial weight loss plan, birth control pills, and FCP — the obese people gained no more than 6.2 pounds (2.8 kg) compared to their peers.

Among thin people, none of the plans resulted in greater weight loss a decade later than if they had done nothing.

This was the same for the overweight group, where they wore up to 15 pounds (7 kg) more than their peers.

The scientists also looked at the participants’ diabetes risk.

Thin people who experienced significant weight loss were up to 54 percent more likely to develop type 2 diabetes than their peers.

But all the obese adults who made plans were less likely to develop diabetes than their peers.

Scientists did not calculate the average numbers among those who made different weight loss plans but fell into the weight category.

Overweight adults who lost weight rapidly were up to 42 percent more likely to develop diabetes than their peers.

Dr Kee Sun, the Harvard epidemiologist who led the study said: ‘We were somewhat surprised when we first saw the positive associations of attempts to lose weight with faster weight gain and an increased risk of type 2 diabetes among thin individuals.

However, we now know that such observations are backed by biology that unfortunately has adverse health outcomes when thin individuals attempt to intentionally lose weight.

“The good news is that obese individuals will clearly benefit from losing a few pounds, and the health benefits persist even when the weight loss is temporary.”

He said the weight loss likely led to biological changes in thin people that put them at greater risk of accumulating pounds later.

It may raise levels of the hunger hormone ghrelin, causing a person to feel hungry more often.

This can also make people more likely to access salty or sugary foods because it activates the area of ​​the brain associated with rewards.

Similarly, the researchers warned that more fat cells – which secrete the hormone ghrelin – may accumulate in thin people in order to increase levels of this hormone.

At the same time, rapid weight loss lowered levels of anorexia hormones — such as leptin — that help suppress hunger.

Studies also show that it causes the body to reduce the amount of energy it burns, to ensure more energy is conserved.
