Many believe Ramadan fasting aids weight loss, yet some people gain weight instead. Research indicates that weight changes depend on total calorie intake, food quality, sleep patterns, and physical activity. Certain poor habits during the fasting month can lead to weight gain.
Ramadan is often seen as an ideal time for weight loss through fasting from dawn to sunset, which helps control calorie intake and improve metabolism. However, in reality, many people experience weight gain. An article from VIVA states that Ramadan fasting does not automatically lead to weight loss, but is influenced by factors like total calorie consumption, food quality, sleep patterns, and physical activity levels.
If habits during fasting increase excessive energy intake while reducing calorie burn, weight gain can occur. According to PMC sources, here are some habits that may contribute:
Overeating at iftar: After a day of hunger, many compensate with large portions. A study from the National Institutes of Health found this can raise total calorie intake during Ramadan, exceeding daily needs and causing weight gain.
Consuming high-fat and high-sugar foods: Dishes like fried items, coconut milk-based meals, and sweets are popular. Research in the Frontiers journal noted increased intake of high-sugar and high-fat foods in some countries during fasting, potentially adding to body fat stores if habitual.
Sweet drinks at iftar: Choices such as syrups, sodas, or sugary juices provide high calories without lasting satiety. The World Health Organization warns that excess sugar during Ramadan risks weight gain and metabolic issues.
