Intermittent fasting isn't a traditional diet—it's more about when you eat than what you eat. The idea is to cycle between periods of eating and fasting. During the fasting window, you avoid food (and calorie-containing drinks), allowing your body to shift into a different metabolic state.
Here are some common ways to do it:
-
12:12 Method: Fast for 12 hours, eat meals within a 12-hour period
-
14:10 Method: Fast for 14 hours, eat meals within a 10-hour period
-
16:8 Method: Fast for 16 hours, eat meals within an 8-hour period
-
20:4 Method: Fast for 20 hours, eat meals within a 4-hour period

Potential Benefits of Intermittent Fasting
Weight loss: Narrowing your eating window may help reduce calorie intake, which can support weight loss. Fasting also helps regulate hunger hormones like ghrelin and leptin, making it easier to control cravings and feel fuller with less food.
Improved blood sugar: Fasting may help your body use insulin more efficiently, which can prevent type 2 diabetes. During fasting, insulin levels drop, allowing your cells to become more sensitive to insulin, so they need less of it to manage blood sugar. This leads to more stable energy levels and fewer insulin spikes.
Heart health: While research is limited, some studies show that intermittent fasting can lower cholesterol, triglycerides, and blood pressure. It may also reduce inflammation and oxidative stress, which contribute to heart disease.
Cellular repair: Fasting activates autophagy, a process where your body clears out damaged cells. This may help protect against aging and disease, though research is still in the early stages.
With that being said, many of these benefits are similar to what you'd get from a regular, healthy diet. Intermittent fasting isn't magic—it just offers a structure that can help some people stay on track.
Potential Risks
Intermittent fasting isn't for everyone, and it can come with downsides—especially if done without a plan.
Blood sugar dips: Fasting can sometimes cause blood sugar to drop too low, especially in the morning or after long fasting periods. This may lead to symptoms like dizziness, fatigue, irritability, and trouble concentrating. People with diabetes or blood sugar issues should consult their healthcare provider before trying fasting.
Nutrient gaps: Skipping meals reduces your chances of getting all the essential vitamins and minerals your body needs.
Hormonal issues: Women’s hormones are more sensitive to changes in diet and fasting because of their reproductive system. Prolonged or frequent fasting can lower estrogen and progesterone, which may cause irregular periods or affect fertility. It can also raise cortisol, the stress hormone, which may interfere with thyroid function and overall hormone balance.
Not for everyone: If you're pregnant, breastfeeding, diabetic, underweight, or have a history of eating disorders, intermittent fasting may not be suitable for you.
What Should You Eat After a Fast?
After a fast, it's best to start with a balanced, easy-to-digest meal. Focus on whole foods with protein, healthy fats, and fiber-rich carbs—like eggs with avocado and whole grain toast, or any fit-flavors meals! Avoid breaking your fast with heavy, greasy, or sugary foods, which can cause blood sugar spikes and digestive discomfort. Eating slowly and staying hydrated also helps your body ease back into digestion.
Conclusion
Intermittent fasting can be a useful tool if it fits your lifestyle. It can simplify eating habits, improve metabolic health, and aid in weight loss, as long as you're consistent and still focusing on quality nutrition
As with anything health-related: listen to your body, consult a doctor if you have underlying health issues, and remember—there’s no one-size-fits-all solution.
