From the Research
Exercising in a fasting state can help decrease cholesterol levels, as evidenced by a study published in 2021 1, which found that a single moderate-intensity exercise bout performed in the fasted state decreased serum total cholesterol and triglycerides in obese male rats. When considering the impact of exercise on cholesterol levels, it's essential to examine the effects of fasting on lipid metabolism. Fasted exercise can enhance fat utilization during workouts, potentially improving lipid profiles over time.
- The study published in 2021 1 suggests that exercising in a fasted state can lead to beneficial adaptations in lipid metabolism, including decreased total cholesterol and triglycerides.
- Another study published in 2020 2 found that exercising during a fasting state increases lipolysis in adipose tissue, stimulating peripheral fat oxidation and resulting in increased fat utilization and weight loss.
- However, it's crucial to note that consistency in exercise matters more than timing relative to meals, and other factors like diet, medication, and overall lifestyle have greater impacts on cholesterol management than exercise timing alone.
- For significant cholesterol concerns, combining regular exercise with a heart-healthy diet low in saturated fats and consultation with a healthcare provider about potential medication options like statins would be more effective than relying solely on fasted workouts.
- The most recent and highest-quality study, published in 2021 1, provides the strongest evidence for the benefits of exercising in a fasting state on cholesterol levels, and its findings should be prioritized when making recommendations.
