Introduction
Intermittent fasting has become an increasingly popular health and weight loss approach. It involves alternating between periods of fasting and eating. Many people try to stick to water, black coffee, herbal tea, and other calorie-free beverages while fasting. But can you eat popcorn while fasting or does it break your fast? Keep reading to learn more.
What is Intermittent Fasting?
Intermittent fasting schedules involve splitting the day or week into eating and fasting periods. Some common approaches include:
16/8 Method
This involves fasting for 16 hours per day and restricting food intake to an 8-hour window. For example, skipping breakfast and only eating between 12-8pm.
Alternate Day Fasting
Fasting every other day, with 500-600 calories allowed on fasting days.
5:2 Diet
Eating normally 5 days per week but restricting calories to 500-600 two days per week.
Time-Restricted Eating
Confining eating to set number of hours per day, such as only 8-10 hours of the day.
Studies show intermittent fasting may aid weight loss, lower blood pressure, improve cholesterol, and regulate blood sugar.
Does Popcorn Break a Fast?
Most experts agree that popcorn will technically break your fast during intermittent fasting. Here's why:
Contains Calories
Popcorn kernels contain calories, so eating popcorn provides energy during your fasted state. Even if you opt for air-popped popcorn without oil or butter, popcorn still has approximately 30 calories per cup.
Stimulates Digestion
When you eat or drink anything with calories during a fast, it triggers digestive processes like the release of stomach acid and digestive enzymes. This stimulates the digestive system, which goes against the goal of fasting.
Creates an Insulin Response
Eating popcorn will cause your blood sugar and insulin levels to rise as your body begins to process and metabolize the carbohydrates and calories. This insulin spike influences energy, hunger levels, and fat metabolism in ways that negatively impact fasting.
Tips for Eating Popcorn While Fasting
If you absolutely must eat popcorn during your intermittent fasting schedule, here are some tips to minimize its impact:
Stick to a Tiny Portion
Restrict your popcorn portion to 1 cup popped or less. This limits calories to 25-30 calories and carbs to about 5 grams.
Avoid Add-Ons
Don't add any oils, butter, or other high-calorie flavorings which drive up calories and trigger more insulin release.
Opt for Air-Popped
Air-popped popcorn is the lowest in calories and fat compared to types popped in oil. Microwave popcorn often has other additives too.
Drink Water
Pair your small popcorn snack with plenty of water to help fill your stomach without additional calories.
Save for a Treat
Only enjoy popcorn occasionally on fasting days, rather than regularly. Have it in the evening vs earlier in your fast.
Healthier Fasting Snack Alternatives
While an occasional taste of popcorn won't sabotage your fast, there are healthier snack options to consider:
Celery and Carrots
Crunchy whole vegetables provide few calories and won't spike blood sugar.
Hard-Boiled Eggs
Eggs are very filling. One large hard-boiled egg has about 80 calories and satisfying protein.
Nuts
A small handful of nuts like almonds, walnuts, or pistachios makes a nutritious fasting snack.
Apple Slices
Apples offer fiber, vitamin C, and antioxidants with a satisfying crunch.
Pureed Soups
Opt for blended vegetable or tomato soup for an extra dose of veggies.
Sugar-Free Jell-O
Jell-O cups provide flavor for very few calories and no added sugar.
Pickles
Pickles offer crunchy low-calorie satisfaction. Opt for no added sugar varieties.
Health Benefits of Intermittent Fasting
Assuming your intermittent fasting approach is nutritionally balanced overall, potential benefits can include:
Weight Loss
By restricting eating windows, fasting may help reduce overall calorie intake and lower body weight over time.
Reduced Inflammation
Fasting periods allow the body to rest from digesting and metabolizing food, which may lower chronic inflammation.
Improved Heart Health
Studies indicate intermittent fasting could benefit heart health by improving cholesterol, blood pressure, and other markers.
Regulated Blood Sugar
Fasting periods allow insulin to normalize, which promotes healthy blood sugar control.
Boosted Brain Function
Animal research suggests fasting may increase factors that boost brain health and cognition like brain-derived neurotrophic factor (BDNF).
Drawbacks of Intermittent Fasting
Potential downsides of intermittent fasting to consider include:
Hunger and Cravings
Fasting periods may significantly increase hunger, food cravings, and obsession with food.
Headaches
Low blood sugar levels during fasting can trigger headaches in some people.
Dehydration
Strict fasting with only water or black coffee leads to greater fluid loss. Dehydration symptoms may occur.
Energy Crash
Dramatically cutting calories with fasting can leave you feeling tired, sluggish, and low on energy.
Disordered Eating
For those prone to eating disorders, strict fasting rules may trigger orthorexia, an unhealthy obsession with healthy eating.
Who Should Avoid Intermittent Fasting
Intermittent fasting is not advised for:
- Children or teenagers
- Pregnant or breastfeeding women
- Those with a history of eating disorders
- People with medical conditions like diabetes or low blood pressure
- Anyone taking prescription medications that must be taken with food
- Those recovering from surgery or illness
- Older adults at risk for malnutrition
Check with your healthcare provider before trying intermittent fasting if you have any concerns.
The Bottom Line
While popcorn does technically break your fast, an occasional 1 cup portion won't sabotage your efforts. For best results, save any popcorn for a special fasting day treat. Focus on more filling, nutritious snacks like whole fruits and vegetables, eggs, nuts, pickles, and pureed soups to control hunger.
Pay attention to your energy, mood, and hunger cues while fasting. If you feel unwell or struggle with cravings, headaches, and fatigue, intermittent fasting may not be the best weight loss approach for you. As with any diet, be sure to eat a healthy well-balanced diet and speak to your doctor, especially if you have any medical conditions.
