Caloric restriction, or eating less food than usual, has been shown to have numerous benefits for overall health and longevity. While many people associate dieting with weight loss and body image, caloric restriction goes beyond just shedding pounds. It involves reducing the amount of food you eat to a level that is lower than your usual intake while still maintaining a balanced diet with essential nutrients.
Research studies on caloric restriction have shown that it can improve various biomarkers of health and may reduce the risk of chronic diseases such as heart disease, diabetes, and certain types of cancer. Here are some of the benefits of caloric restriction:
- Increases lifespan: Caloric restriction has been shown to increase the lifespan of various animals such as mice, rats, and monkeys. While studies on humans are limited, some research suggests that caloric restriction may also increase the lifespan of humans.
- Improves heart health: Caloric restriction has been shown to reduce the risk of heart disease by improving blood pressure and cholesterol levels and reducing inflammation in the body.
- Reduces the risk of diabetes: Caloric restriction has been shown to improve insulin sensitivity, which may reduce the risk of developing type 2 diabetes.
- Slows the ageing process: Caloric restriction has been shown to slow the ageing process by reducing oxidative stress and inflammation in the body, two factors contributing to ageing.
- Improves cognitive function: Caloric restriction has been shown to improve cognitive function by increasing the production of brain-derived neurotrophic factor (BDNF), a protein that helps with the growth and survival of brain cells.
While caloric restriction may sound challenging, it doesn’t have to be overly restrictive or difficult. Research suggests that even small reductions in calorie intake can have significant health benefits. Adopting healthy eating habits such as reducing portion sizes, limiting sugary and processed foods, and increasing intake of fruits and vegetables can be a great way to start.
It’s important to note that caloric restriction may not suit everyone. Pregnant or breastfeeding women, children, and people with certain medical conditions should consult their healthcare provider before starting a caloric restriction diet.
In conclusion, caloric restriction has been shown to have numerous health benefits and may even increase lifespan. While it may not be suitable for everyone, adopting healthy eating habits and reducing calorie intake in a safe and sustainable way can be a great way to improve overall health and longevity.
