Benefits of Calorie Restriction in Humans
Calorie deficiency happens when you " reduce the number of calories throughout the day by 30-60% but without treading into the territory of malnutrition." Although, calorie deficiency can be harmful and lead to an eating disorder. There's many benefits health wise to calorie restriction. One calorie restriction benefit is that it can increase one's lifespan. This happens by " increasing the levels of dehydroepiandrosterone (DHEA), through xenohormesis, a process where plants pass on their stress-resilient phytonutrients, and/or through the inhibition of the enzyme TOR." Another benefit is weight loss by decreasing your daily calorie intake. By pairing this with exercise, weight loss will be more easy to achieve. Many doctors recommend calorie restriction to those that are overweight to prevent any health problems that could arise. Research shows that calorie restriction is more effective than fat restriction. In the experiment, "There was a significantly greater decrease in percent body fat and resting metabolic rate for the low calorie group with only percent body fat still significantly lower at 18 months." This means not only did calorie restriction cause weight loss, but it also reduce the percent body fat. As well as, decrease risk of many health problems such as, diabetes, stroke, and heart disease. A experiment proved that those who calorie restrict have lower cholesterol levels, lower triglycerides, and lower systolic and diastolic blood pressure. This helps improve their quality of life since they will be healthier. Calorie restriction causes a loss in muscle mass, but the positive to this is "the diet is able to preserve the quality and function of muscle with age." This keeps the muscle young and keeps function for longer.

Gender Differences in Calorie Restriction
Different bodies react to calorie restriction diet in different ways. One factor that can change how the body reacts is gender influence. In a recent study they determined that "a low-calorie diet causes different metabolic effects in women than in men." After eight weeks of 2,000 overweight people participating in a low calorie diet, they determined that the men lost a lot more body weight than the women in the study.
