Calorie restriction (CR) is a dietary approach that focuses on eating fewer calories than you would normally consume. It involves reducing caloric intake but still consuming enough healthy and nutritionally nutritious foods to meet one’s nutritional needs. In other words, CR is a way of managing your energy balance without becoming starved or undernourished.

How Does It Work?
Calorie restriction encourages people to limit the number of calories that they consume from all sources, including fats, proteins and carbohydrates. On average, it involves reducing calorie intake by about 30-50% below the amount consumed in a normal diet. Many people adopt this approach as an effective weight loss tool, although some maintain it as a long-term lifestyle choice.
Researches suggest that CR results in several health benefits such as improved longevity or reduced risk for diseases like cancer and heart disease. Other research suggests that simply taking in fewer calories can beneficially affect cell metabolism, reduce oxidative stress and inflammation; however, more research with humans needs to be done to confidently confirm these potential health benefits of CR.
Risks Associated with Calorie Restriction
Although CR has generally been associated with good health outcomes, very strict calorie restriction can actually lead to nutritional deficiencies and similar health issues. Monitoring your dietary intake is essential to prevent potential health risks due to nutrient deficiencies. Additionally, because calorie needs change over the course of the day while eating smaller portions throughout the day, individuals will need to take food quality into consideration when reducing their calorie intake.
Tips for Practicing Calorie Restriction Successfully
If you’re considering increasing your daily energy efficiency by reducing your calorie consumption, keep in mind that it’s all about finding the right balance between what you eat and how much. Here are a few tips for practicing CR safely and effectively:
- Choose nutrient-dense foods like whole grains, fruits, vegetables and lean proteins rather than processed or fast foods
- Prioritize meal planning so that you know what meals you’ll prepare in advance
- Manage portion sizes–including snacks–and don‘t overindulge on unhealthy food options
- Properly hydrate throughout the day 34 Keep track of your calorie intake
- Listen to your body’s hunger and fullness signals
- Focus on quality sleep for better weight control
Summary
Most of us know that eating healthy and limiting calories is essential for a healthy lifestyle. Calorie restriction (CR) focuses on reducing the amount of calories consumed while still providing essential nutrition. Even though research shows initial health benefits, it’s important to practice CR safely and consciously by monitoring food intake, quality and portions. With careful planning, you can enjoy the many potential benefits that calorie restriction has to offer.
