• Whey Isolate: ≥90% pure protein, low lactose/fat, rapid absorption.
• Whey Concentrate: 70–80% protein, higher bioactive compounds and BCAAs, slightly more lactose/fat.

Supporting Ingredients: CLA, Green Tea, L-Carnitine – Benefits & Clinical Evidence

• Average 1-2g CLAs per serving show modest fat reduction effects in 12–24 week studies (mean change -0.7kg vs control, p<0.05).
• L-Carnitine supplementation in diets & exercise have shown an extra -1.33kg fat mass reduction over 8–12 weeks vs. placebo (2025 meta-analyses).
• Green tea extracts with >300mg EGCG daily linked to modest metabolic increases and small, consistent fat loss compared to placebo (~3-4% energy expenditure increase).

How Diet Whey Supports Weight Management & Lean Muscle (2026 Research)

• Diet Whey’s blend increases satiety and thermogenesis, helping reduce total energy intake.
• High-protein/low-carb diets in clinical trials resulted in 2–4kg more fat loss and greater muscle mass preservation over 12–24 weeks compared to standard protein, calorie-deficit diets (2026 systematic reviews).
