Calorie restriction (CR), or caloric restriction, or energy restriction, is a dietary regimen that reduces calorie intake without incurring malnutrition or a reduction in essential nutrients. "Low" can be defined relative to the subject's previous intake before intentionally restricting calories, or relative to an average person of similar body type. Calorie restriction without malnutrition has...

Impulsivity and food craving have both been implicated in overeating. Recent results suggest that both processes may interactively predict increased food intake. In the present study, female participants performed a Go/No-go task with pictures of high- and low-calorie foods. They were instructed to press a button in response to the respective target category, but withhold responses to the other...

Background: In addition to reducing body weight, the low-calorie diets can reduce the lean body mass. It is hypothesized that in addition to reducing the body weight, the low-calorie diets can maintain the lean body mass. So, the current study aimed at evaluating the effects of high-protein diet with calorie restriction on body composition in overweight and obese individuals. Methods: 36 obese ...

Abstract Overweight and obesity has increased in prevalence over the last two decades in many developed and developing countries including Iran. The aim of this present study was to compare the weight reduction effects of ketogenic and low calorie diets on overweight and obese Iranian children. Seventy-six overweight or obese children aged 9-16 years recruited from outpatient Ghaem Hospital, Nu...

BACKGROUND Nonpharmacological interventions have been efficacious to control blood pressure (BP) in clinical trials, but their long-term effectiveness in clinical practice was still not documented. METHODS This is a prospective cohort study of 825 patients who received repeated nonpharmacological recommendations to treat hypertension. The outcomes were BP change and rate of BP control by patt...

Aims To investigate the impact of unit and calorie information on drinking behaviour in an ad libitum taste test paradigm. Methods In this experimental human laboratory study, participants were randomized to one of four conditions, balanced by gender, using a 2 (unit information: present vs. absent) × 2 (calorie information: present vs. absent) between-subjects design. The percentage of beer ...

Changing food consumption patterns and associated greenhouse gas (GHG) emissions have been a matter of scientific debate for decades. The agricultural sector is one of the major GHG emitters and thus holds a large potential for climate change mitigation through optimal management and dietary changes. We assess this potential, project emissions, and investigate dietary patterns and their changes...

In the current study we examined an associative learning mechanism by which food cues (signaling low- versus high-calorie food) can bias instrumental responses directed toward those foods. To investigate the clinical relevance of this mechanism, we used a computerized Pavlovian-to-instrumental transfer task and compared performance of 19 severely obese individuals to that of 19 healthy-weight c...
