Tamannaah Bhatia’s trainer, Siddhartha Singh, has weighed in on the fitness fads that should be left in 2025. His advice is simple and practical: forget quick fixes and focus on long-term, sustainable habits.

Siddhartha has highlighted three major trends he believes do more harm than good and encourages people to return to the fundamentals of healthy living.

1. Low-Carb Diet vs Calorie Deficit
Crash low-carb diets may promise rapid weight loss, but Siddhartha cautions against eliminating carbohydrates, especially for those who work out regularly.ET logoLive Events”You will probably lose weight very fast, but your hormones will crash, and cravings will kill you, literally. Instead, do a calorie deficit. Enjoy your carbs and eat a lot of protein.”
He recommends maintaining a moderate calorie deficit rather than cutting out entire food groups. According to him, balance is key — especially ensuring adequate protein intake while still enjoying carbohydrates in moderation.
2. Detox Teas
Siddhartha also criticises the supplement industry, particularly detox teas and cleansing products, calling them ineffective and misleading.

“No tea or supplement can detox you,” he says, stressing that the body already has natural detox mechanisms in place.

Instead of relying on so-called miracle drinks, he advises focusing on basics such as fibre-rich foods, sufficient protein intake, daily movement, and quality sleep. Supporting the body’s natural systems, he believes, is far more effective than chasing quick results.

3. Not Getting Enough Sleep
Another major mistake, according to Siddhartha, is neglecting sleep due to busy lifestyles. Poor sleep doesn’t just cause fatigue — it can directly hinder fat loss and recovery.

“If your sleep is poor, it’s going to increase cravings. It’s going to slow down recovery, which is going to actually lead to you storing more fat in your body,” he explains.

For anyone serious about improving body composition, Siddhartha insists that getting 7–8 hours of uninterrupted sleep each night is non-negotiable.
