Intermittent fasting is a popular diet trend claiming numerous health benefits, including weight loss, reversing diabetes, and even increasing lifespan. You may have heard people talk about intermittent fasting, but what exactly is it, and is it safe for everyone? As a registered dietitian, I'm here to share some insight into this diet trend and help you determine if it's right for you.
What is intermittent fasting?
Intermittent fasting is not a diet in the traditional sense but rather a pattern of eating. There are several types of it, but the most popular ones are a 5:2 diet, a 16:8 diet, and alternate-day fasting. The 5:2 diet involves eating normally for five days and restricting calories to 500-600 for two non-consecutive days a week. The 16:8 diet involves fasting for 16 hours and having an 8-hour eating window. Sometimes, this is also called time-restricted eating. Alternate-day fasting involves eating normally one day and limiting calorie intake to 500-600 the next day.
How does it help with weight loss?
Intermittent fasting helps with weight loss by decreasing overall calorie intake. Furthermore, when we fast, our body uses stored energy from fat cells for fuel rather than glucose from food. The restricted calorie intake also leads to a decrease in insulin, resulting in increased fat burning. Over time, this can lead to weight loss.
Who is it suitable for, and who should avoid it?
Intermittent fasting may not be suitable for everyone. Pregnant women, people with a history of eating disorders, individuals with diabetes who take medications that lower blood sugars, and those with a low BMI should avoid fasting. If you have any pre-existing medical conditions, you should always check with your healthcare provider before trying intermittent fasting.
Can it reverse diabetes?
Some research suggests that intermittent fasting may help reverse type 2 diabetes by improving insulin sensitivity, reducing inflammation, and promoting weight loss. However, if you're on medication for diabetes, it's important to consult your healthcare provider. Your medication may need to be adjusted to avoid hypoglycemia.
Is intermittent fasting right for you?
Intermittent fasting can be a safe and effective weight loss tool for many people, but it's not a one-size-fits-all approach. If you decide to try intermittent fasting, start gradually and listen to your body. It's essential to ensure that you're still consuming enough nutrients in your eating windows to support your body's needs. If you're struggling with weight loss or want to try something new, intermittent fasting may be worth exploring.
Final Thoughts
Intermittent fasting has become a popular diet trend in recent years and with good reason. It can lead to weight loss, improve insulin sensitivity, and potentially even reverse diabetes. However, it's essential to recognise that it's not for everyone and that it's important to consult your healthcare provider before starting any diet or exercise program. At the end of the day, the most important thing is to find a healthy lifestyle that works for you, whether that includes intermittent fasting or a different approach.
