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?

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.

These studies have found that body weight is more related to genetic factors than the number of calories ingested by an individual.

We can arrive at this answer because:

The two studies presented in the question above were aimed at evaluating the effects of excessive and small amounts of food on body weight and functioning.

The Vermont prison study focused on gradually increasing food intake for prisoners, who exhibited varying weight gain, even though they ate the same calories.
The study by Keys and his colleagues studied the effects of very small amounts of food on the human body and also observed variable weight loss among volunteers.
This showed that body weight, despite being influenced by calorie intake, is more linked to genetic factors.

However, this does not mean that the excess or lack of calories did not show strong effects in the volunteers, since the number of calories affected mood, triggered depressive symptoms, irritability, difficulty concentrating, among other problems.
