Social media is rife with rapid weight loss tips that vow stunning changes in mere days. A viral list from a fitness influencer outlines 15 rules for shedding 15 kg in 15 days, such as kicking off the morning with jeera water, sticking to an 8 AM–8 PM eating window, ditching maida and sugar, practicing carb cycling, incorporating protein into every meal, having salads before meals, restricting oil, scheduling fruit intake, skipping chai after 4 PM, and including a weekly “detox day.” But are these claims realistic—or safe? We consulted Aditi Prasad Apte, Senior Clinical Nutritionist at Aster RV Hospital, for verification. DISCLAIMER: This article draws from publicly available information and/or insights from the experts we interviewed. Always check with your doctor before beginning any regimen. Is it truly possible to shed 15 kg in 50 days? Short answer: No, not safely. Per Apte, “Losing 15 kg in 50 days is not a realistic or sustainable goal.” It merely sheds water weight and fails to burn fat. Rapid weight loss like this usually results from severe calorie cuts, which can have unintended negative effects. “Drastically reducing calories right away can also cause severe nutrient deficiencies and muscle loss, resulting in fatigue, irritability, and a sudden decline in immunity,” she warns. Why extreme diets don’t work long-term.
