The Truth About Carbs, Protein, and Creatine: Science Sets the Record Straight

A landmark analysis of 37 randomized trials involving over 3,286 participants found that low-carbohydrate and balanced-carbohydrate diets produce nearly identical weight loss over three to eight and a half months. The mean difference? Just 1.07 kg — a negligible gap that renders the 'carbs make you fat' narrative scientifically outdated. Both diets led to similar reductions in diastolic blood pressure, LDL cholesterol, and HbA1c, with differences under 0.5 mmHg, 0.12 mmol/L, and 0.14% respectively. This means your choice should be based on sustainability, not false promises of metabolic superiority.

For the average person trying to lose weight, this is liberating news. You don’t need to eliminate bread, rice, or fruit to shed pounds. What matters more is total calorie control, protein intake, and adherence. The obsession with carb restriction often leads to nutrient deficiencies and unsustainable eating patterns. If you thrive on low-carb, great. But if you prefer balanced meals, you’re not falling behind.

The bottom line: Neither low-carb nor balanced-carb diets are superior for short-term weight loss — choose what you can stick with.

For adults aged 65 and older, increasing protein intake beyond the standard 0.8 g/kg/day may modestly boost lean body mass — but not total body weight. Seven out of 18 randomized trials showed gains between 0.8 kg and 2.0 kg of lean mass after 10–12 weeks, even when participants were already consuming adequate protein. This suggests that the current RDA may be too low for aging populations fighting sarcopenia.

Importantly, these gains didn’t translate to weight loss or improved mobility in all cases, and results were inconsistent across studies. Still, for older adults, preserving muscle is critical for independence, fall prevention, and metabolic health. Aim for 1.2–1.6 g/kg/day from sources like eggs, Greek yogurt, lean meats, and legumes. No need for expensive supplements — whole foods work.

Extra protein helps seniors build muscle, but won’t make them lighter — and that’s exactly what they need.

A 12-week randomized controlled trial directly challenged the viral claim that creatine causes hair loss by elevating DHT. Researchers gave 5g/day of creatine monohydrate to healthy, resistance-trained young men and measured DHT levels and hair loss markers. Result? No significant increase in DHT, and no detectable hair thinning compared to placebo. This contradicts a small, flawed 2009 study that sparked widespread fear.

Creatine remains one of the most researched, safest supplements in sports science. It improves strength, power, and recovery — with no credible evidence linking it to baldness. The myth likely persists because creatine users are often young men already prone to genetic hair loss, creating a false correlation.

Creatine supplementation does not cause hair loss — it’s safe, effective, and your gains aren’t paying the price.
