Fast Track Fasting: Techniques, Advantages, Drawbacks, and FAQs
Intermittent fasting, a popular dietary approach, has been gaining traction for its potential benefits in weight loss and overall health improvement. This practice involves abstaining from eating for a fixed period, such as fasting for two days per week, and then eating a regular diet for the remaining five days.
A study published in 2017 found that intermittent fasting led to similar levels of significant weight loss as a traditional eating plan [1]. The fast diet, a popular intermittent fasting method, suggests females consume 500 calories and males 600 calories on fasting days [2].
While intermittent fasting dictates *when* to eat, not *what* to eat, implementing certain strategies can reinforce healthy eating habits. These include prioritizing nutrient-dense foods such as vegetables, lean proteins, healthy fats, and complex carbohydrates during eating windows [2][4]. Increasing protein and fiber intake can promote fullness and reduce cravings, making it easier to avoid unhealthy, calorie-dense foods on non-fasting days [1].
Eating balanced meals regularly, avoiding eating late at night, staying hydrated, planning and preparing meals, practicing mindful eating, and using calorie-free beverages like unsweetened tea can also support a healthy and balanced diet on non-fasting days [1][2][4].
Intermittent fasting may lead to weight loss, but it may also cause side effects such as changes in mood, extreme hunger, low energy, obsessive thoughts about food, overeating on days without restricted calories, binge eating behavior, tension, depression, anger, fatigue, confusion, and feelings and behaviors are most common in the first few weeks [3].
Some studies suggest that intermittent fasting may extend lifespan by decreasing insulin-like growth factor-1 (IGF-1) levels [5]. It may also potentially reduce the side effects of chemotherapy and increase its effectiveness in some cancer patients [6].
However, intermittent fasting is not recommended for everyone. People with underweight, eating disorders, type 1 diabetes, medication-controlled type 2 diabetes, pregnancy or breastfeeding, recent surgery, mental health conditions, fever or illness, conditions for which they take warfarin, and those participating in endurance events or special occasions, social gatherings should avoid intermittent fasting [7].
Alternate day fasting, a method where people fast every other day, consuming a single 500-calorie meal at lunchtime on fasting days, is another form of intermittent fasting [8]. Daily intermittent fasting restricts eating to a certain number of hours each day, such as the 16:8 diet [9].
In conclusion, intermittent fasting can be a valuable tool for weight loss and health improvement when practiced responsibly and in conjunction with a balanced diet. It is essential to consult with a healthcare provider before starting any new dietary regimen.
