Fasting and HIIT: A Long-Term Combo for Better Health
Share
We’ve all heard about new diet and fitness trends, but many of them come and go. What really matters is whether these strategies actually work in the long run. Good news: a recent study followed women for two years and found that fasting (specifically, time-restricted eating) and high-intensity interval training (HIIT) may help with lasting weight loss and health improvements. Let’s break down what this means—and how you can apply it to your life.
What Is Time-Restricted Eating?
Time-restricted eating (TRE) is a simple form of intermittent fasting. Instead of focusing on what you eat, TRE focuses on when you eat. For example, you might eat all your meals between 10 a.m. and 6 p.m., then fast for the remaining 16 hours.
This eating pattern gives your body more time to burn fat, rest your digestive system, and regulate hormones like insulin. Many people find TRE easier to follow than traditional calorie-counting diets because it’s about timing, not restriction.
What Is HIIT?
High-intensity interval training (HIIT) is a type of workout that alternates between short bursts of intense activity (like sprinting or jumping) and brief recovery periods. A typical HIIT session might last 20–30 minutes and include exercises like squats, burpees, or fast cycling.
HIIT is popular because it’s time-efficient, burns calories quickly, and continues to boost your metabolism even after your workout is over.
The Study: What Happened Over 2 Years?
Researchers in Norway followed a group of women with overweight or obesity who had taken part in a 7-week intervention combining TRE and HIIT. Two years later, they wanted to see what stuck.
Here’s what they found:
- Many of the women had kept using TRE and/or HIIT in their routines, even after the study ended.
- Those who maintained the habits had lower body fat and better waist measurements than when they started.
- Some health markers, such as cholesterol and blood sugar levels, also improved or stayed stable.
The takeaway? TRE and HIIT weren’t just short-term fixes—they helped these women maintain a healthier lifestyle over the long haul.
Why Does This Matter?
Most weight-loss programs focus on short-term success. But what happens months or years later? This study is important because it shows that:
- Simple habits like fasting and short workouts can be sustainable
- Lasting changes don’t always require drastic diets or hours in the gym
- Small, consistent efforts can lead to real health improvements
In a world full of quick fixes, TRE and HIIT offer a realistic and effective long-term approach.
How to Get Started
If you’re curious about adding fasting or HIIT to your routine, here are some tips:
1. Start slow with TRE
Try a 12-hour eating window at first (e.g., 8 a.m. to 8 p.m.), and shorten it as you get used to it.
2. Listen to your body
Fasting isn’t for everyone. If you feel dizzy, weak, or overly hungry, adjust your schedule or consult a doctor.
3. Try beginner HIIT workouts
You don’t need fancy equipment. Start with 20 minutes of bodyweight moves like jumping jacks, squats, and lunges.
4. Combine both for best results
Fasting and HIIT can work even better together. Try exercising toward the end of your eating window for energy and recovery.
5. Be consistent, not perfect
You don’t have to follow TRE or do HIIT every day. A few times a week can still make a difference over time.
Final Thoughts
Fasting and HIIT may sound like just another health trend, but this research shows they can offer real, lasting benefits when done safely and consistently. If you're looking for a flexible, science-backed way to support your weight and health goals, combining these two approaches could be a smart move.
As always, talk to your doctor before starting any new diet or workout routine—especially if you have underlying health conditions. But if you’re ready for a fresh, practical approach to long-term health, fasting and HIIT might be your winning combo.
