How Many Calories Should You Eat to Lose Weight?
Discover the science behind calorie deficit and how to calculate the right amount for your body.
Not a diet. A rhythm. Intermittent fasting (IF) isn't about counting every calorie. It's about when you eat— and letting your body rest in between.
IF is an eating pattern that cycles between periods of eating and fasting. Popular methods include:
Let’s be honest—it’s not just about health. People fast for simplicity. No breakfast. Fewer decisions. Less snacking. More control. But here’s what the science says it can help with:
During fasting, your body increases production of norepinephrine, which can help sharpen your attention. Many report greater focus in the morning while fasting.
Once glycogen stores are depleted, the body switches to burning fat. Fasting can increase fat oxidation—especially when combined with exercise.
Fewer meals = fewer insulin spikes. Intermittent fasting may help improve insulin sensitivity and stabilize blood sugar levels over time.
Fasting triggers a process called autophagy—your body’s way of cleaning out damaged cells and regenerating new ones. This is linked to longevity and disease prevention.
If you have a history of eating disorders, are pregnant, or take medications that require food—consult a healthcare professional first. Fasting is a tool, not a universal solution.
You don’t need to jump straight into a 24-hour fast. Try delaying breakfast. Try 14:10. See how your body responds. Track how you feel, not just what the scale says.
