In a world obsessed with “instant” transformations and viral wellness hacks, celebrity fitness trainer Siddhartha Singh—the man behind Tamannaah Bhatia’s toned physique—is calling for a return to basics.
Taking to Instagram on February 9, 2026, Singh debunked three popular shortcuts that he believes do more harm than good for long-term health.
1. The Low-Carb Craze
While cutting carbs can lead to rapid initial weight loss, Singh warns that the biological cost is too high.
- The Risk: Drastic carb reduction can cause hormone crashes and intense, uncontrollable cravings.
- The Solution: Instead of demonizing an entire food group, Singh advocates for a sustainable calorie deficit. He suggests eating high protein to preserve muscle and keeping “good carbs” in your diet to keep your metabolism and hormones stable.
2. The “Detox Tea” Deception
Singh offered a blunt reality check on the supplement industry’s marketing of “cleansing” products.
- The Myth: That a tea or pill can “flush out” toxins from your system.
- The Truth: “There is no supplement in the world that can detox you,” Singh stated, reminding fans that the body already has its own sophisticated detox systems (the liver and kidneys).
- Better Support: Focus on high fiber, daily step counts, and consistent hydration to support your body’s natural functions.
3. Neglecting Sleep Hygiene
In a “hustle culture” where four hours of sleep is often worn as a badge of honor, Singh labels poor sleep as a fundamental fitness failure.
- The Consequence: Lack of rest increases hunger-regulating hormones (ghrelin), slows down physical recovery, and actually leads to the body storing more fat.
- The Mandate: For 2026, Singh insists that 7 to 8 hours of “unconditional” sleep is non-negotiable for anyone serious about body composition.
