Bollywood filmmaker Karan Johar's dramatic 20-kilogram weight loss in just seven months has sparked widespread debate about the controversial OMAD (One Meal A Day) diet he used to achieve his transformation. While the director's results appear impressive, medical experts are raising serious concerns about the extreme intermittent fasting method.
The Filmmaker's Dramatic Journey
Speaking with entrepreneur Raj Shamani, Johar revealed he followed a strict one-meal-a-day regimen, eating only around 8 or 8:30 p.m. for seven months. His diet eliminated gluten, sugar, and lactose completely, representing one of the most extreme dietary restrictions undertaken by a Bollywood celebrity.
"The initial seven days were tough; I committed to the routine for seven months, eating once daily between 7 and 8 PM," Johar explained, dismissing speculation that he used weight-loss drugs like Ozempic or Mounjaro.
The director also revealed that his weight loss journey began after addressing thyroid fluctuations and dealing with body dysmorphic disorder, making his transformation even more complex from a medical perspective.
What Exactly Is OMAD?
OMAD or One Meal a Day is a form of intermittent fasting where you eat within a one-hour window and fast for the rest, consuming only non-caloric beverages. This extreme version of time-restricted eating has gained popularity among celebrities, with some reports suggesting Shah Rukh Khan has also experimented with similar methods.
Proponents claim it can lead to faster weight loss, improved digestion, and better insulin sensitivity, making it attractive to those seeking rapid results.
Medical Experts Sound Alarm
Despite Johar's success, healthcare professionals are expressing serious reservations about OMAD's safety and sustainability.
Cardiovascular ConcernsA 2024 study found that people who followed time-restricted eating patterns were 91% more likely to die of cardiovascular disease, raising red flags about dramatic intermittent fasting approaches like OMAD, particularly for individuals with underlying health conditions.
Nutritional Inadequacy RisksRegistered dietician Sophie emphasizes the fundamental problem with OMAD: "It's virtually impossible to make sure your one meal per day meets all your nutritional needs. It's not a diet I would advise."
Psychological ImpactMental health experts warn that "the OMAD diet could certainly trigger behaviours associated with eating disorders in those who are vulnerable," making it particularly concerning for individuals with pre-existing body image issues like Johar's admitted body dysmorphic disorder.
The Harsh Reality of OMAD
Medical professionals point to obvious drawbacks including "extreme hunger, lack of energy, fatigue and uncontrollable cravings," along with fasting-induced headaches. These side effects can significantly impact daily functioning and mental wellbeing.
Research shows that intermittent fasting regimens like OMAD have a dropout rate of up to 65%, and the approach "may make you hungrier" as the body produces more ghrelin, the hunger hormone.
Expert Recommendations
Healthcare providers emphasize that "there is not much research on the safety and benefits of the OMAD diet. It is best to speak with a doctor before trying it or making any other significant changes to your diet."
Top concerns among medical professionals include "rebound weight gain, increased hunger, and nutritional inadequacy," suggesting that Johar's results may not be sustainable long-term.
A Safer Alternative Approach
Some experts suggest that "another option could be to use the OMAD approach once in a while instead of every day," rather than the extreme seven-month commitment Johar undertook.
Medical professionals recommend consulting healthcare providers before attempting any extreme dietary changes, particularly for individuals with thyroid conditions, mental health concerns, or other underlying medical issues.
While Karan Johar's 20-kilogram weight loss demonstrates OMAD's potential for rapid results, the mounting medical evidence suggests this extreme approach carries significant health risks that may outweigh its benefits for most people.
