Question

The short-term and long-term effects of dieting have been documented, such as inmates’ dietary changes in the Vermont prison study (1966) and volunteers’ semistarvation practices in the study by Keys and his colleagues (1950). What did these studies find about weight gain and weight loss as it relates to eating?

Answer 1

Answer:

that the body can recover by  itself

Explanation:

In the first study (Vermont prison study) the volunteers gain around 20 % more of their normal weight by changing their diets with more carbohydrates and oils, but after some months, when they stop this diet, the body can recover their metabolic rates, because the amount of fat cells they just expand, they did not produce more.

In the second study (semistarvation study) the scientist discover that having a diet low in carbohydrates and doing plenty of exercise, simulating the conditions of population in the second world war, they discover that the effects in the body it was not just physical (lost of weight at around 25 %) but also phycological, they become sluggish, depressed and irritable. Also the metabolic rate decelerates to be used to the small quantity of calories in the body.

Answer 2

It is better to eat according to the needs of the human body, no more and no less, because both excess and underweight will interfere with the body's metabolism.

Further Explanation

In 1964, researchers at the Vermont College of Medicine asked volunteers to add 15% to 25% of their body weight in less than three months. Where the researchers focused on adding calories to prisoners. The study was carried out for ten weeks, during which the prisoners were fed with 8,000 to 10,000 calories. From these results, it was found that the prisoners gained between 15 and 25% of their body weight. This study revealed an interesting phenomenon in which researchers found that the metabolic rate of prisoners overdrives after over-feeding. This research is a true illustration of what happens when someone who is overweight tries to lose weight. If the setpoint is too high and wants to lose weight quickly, the body will struggle to maintain weight and slow down the body's metabolism.

Voluntary semi-voluntary practice in a study by Keys and his colleagues (1950) is a clinical study conducted between November 19, 1944, and December 20, 1945. This study was conducted to determine the physiological and psychological effects of severe and prolonged dietary restrictions and the effectiveness of rehabilitation strategies diet.

This program is carried out for a year which is divided into 4 phases, namely:

• Control period (12 weeks)
• Semi-starvation Period (24 weeks)
• Limited rehabilitation period (12 weeks)
• Unlimited rehabilitation period (8 weeks)

From the results of a 1-year study, it was concluded that prolonged semi-starvation produced a significant increase in depression, psychology, and physicality of volunteers. Where the volunteers experienced a decrease in body temperature, breathing, and heart rate.
