What is Intermittent Fasting and Why is Everyone Talking About It?
What is intermittent fasting? It’s not just a fad diet—it’s an eating pattern based on when you eat, not what you eat. Intermittent fasting (IF) alternates between episodes of eating and fasting, and has received huge amounts of attention for its simplicity, flexibility, and evidence-based health effects.
People across the globe—from health enthusiasts to busy professionals—are adopting intermittent fasting because it aligns with our natural circadian rhythms and promotes fat loss, metabolic health, and even longevity.
According to Harvard Medical School, intermittent fasting may improve insulin sensitivity, lower inflammation, and help manage chronic conditions like obesity and type 2 diabetes.

Intermittent Fasting for Weight Loss: Does It Really Work?
Intermittent fasting to lose weight works well because it naturally reduces your calorie intake and makes your body more efficient at burning fat. During fasting, your body uses up its glycogen reserves and begins to burn fat as a primary source of energy.
In 2020, research in the New England Journal of Medicine maintained that intermittent fasting leads to significant fat loss at the cost of lean muscle mass.
Aside from losing fat, it also lowers insulin, suppresses appetite with the regulation of ghrelin and leptin hormones, and lowers fat around the stomach area—making it an effective measure among obesity condition individuals.

When selecting the optimal intermittent fasting for weight loss, it is all about your lifestyle, health condition, and personal preference.

Benefits of Intermittent Fasting Backed by Science
The benefits of intermittent fasting go far beyond weight loss. Evidence shows an impressive array of health advantages:
- Metabolic Health:
Fasting improves insulin sensitivity and reduces inflammation—two of the best predictors of metabolic well-being. The National Institutes of Health (NIH) trial correlated IF with healthier blood lipid levels and reduced blood pressure. - Fat Loss:
IF specifically targets visceral fat—harmful fat surrounding organs. It is effective at reducing waist size and BMI. - Blood Sugar Control:
Intermittent fasting has reduced fasting glucose and enhanced HbA1c in type 2 diabetics. - Cell Repair and Anti-Aging:
Fasting induces autophagy, whereby cells kill offending elements, potentially reversing aging and cancer vulnerability.
Who Should Avoid Intermittent Fasting?
Although intermittent fasting is safe for most individuals, there are some people who should not do it or be cautious about it:
- Pregnant or lactating women.
- Children and adolescents below the age of 18.
- Individuals with a history of eating disorders.
- Individuals on insulin or blood pressure medication.
- Individuals who are underweight or have micronutrient deficiencies.
Note: Always consult a medical doctor before embarking on intermittent fasting, particularly if you suffer from any health condition.
Tips to Get Started with Intermittent Fasting
It does not have to be difficult to start intermittent fasting. Some useful tips are given below:
- Begin slowly: Start with a 12-hour fast and progress gradually.
- Drink plenty of water: Have plenty of water, herbal tea, or black coffee during the fast.
