Intermittent Fasting
Intermittent fasting has gained significant attention in recent years. It's a pattern of eating that alternate between periods of fasting and eating and can be achieved in various ways.
Popular Intermittent Fasting Methods
The 5:2 Diet: Eat normally for five days of the week, then restrict your energy consumption to around 2000-2500 kilojoules per day on two days of your choosing (either consecutive or non-consecutive).
Alternate Day Fasting: Eat normally one day, then fast or consume a small meal the next day.
Time-Restricted Eating: Such as the 16/8 method, where you fast for 16 hours (including overnight) and eat within an 8-hour window during the day.
These low energy diets are designed so that during the fasting period, your body taps into fat stores and preferentially burns fat for energy. Based on client feedback, the results have been predominantly positive.
Potential Benefits
Weight loss
Improved blood glucose control
Enhanced gut health due to reduced digestive load
Better sleep quality
Lowered risk of type 2 diabetes
Reduced inflammation
Interestingly, research has shown that energy restriction reduces oxidative stress in animals and has increased lifespan in rhesus monkeys.
Important Considerations
However, intermittent fasting is not for everyone. It may cause side effects including:
Hunger
Irritability
Headaches
Bad breath
The dropout rate for people attempting this type of diet may be as high as 50%.
Who Should Avoid Intermittent Fasting
Intermittent fasting is unsuitable for:
Diabetics
Children and teenagers
Pregnant or breastfeeding women
Those with certain medical conditions
Individuals with a history of eating disorders
Dietary restriction through intermittent fasting may also contribute to nutrient deficiencies. Therefore, medical supervision is essential.
Conclusion
Like any weight loss approach, there is no one-size-fits-all solution. You're better off finding what works for your lifestyle and preferences. Intermittent fasting could be considered an extreme dietary regime that may not suit everyone. A more moderate plan that's easier to maintain long-term might be better for sustainable success.
