20g protein + CLA and green tea diet-whey blend

Applied Nutrition Diet Whey is a multi-source protein powder built for trainees in cut phases who want their protein shake to include thermogenic and metabolic support ingredients alongside the protein hit. Each 25g serving delivers 20g of protein at 101 calories, with 1.92g of fat (0.46g saturated), 1.02g of carbohydrates and just 0.9g of sugar. The 1.8kg tub provides 72 servings.

The protein blend uses five sources: whey protein concentrate, micellar casein, milk protein concentrate, whey protein isolate and soy protein isolate, providing a mix of fast and slow-digesting protein fractions for sustained amino acid delivery and satiety. The 4317mg BCAA content supports muscle protein synthesis. The diet-support layer adds CLA at 100mg (conjugated linoleic acid researched for lean body composition), Acetyl L-Carnitine at 300mg (supports fatty acid transport into mitochondria) and Green Tea Extract at 200mg (catechins with research-backed thermogenic effects).

What separates Diet Whey from a standard whey concentrate is the bundled diet-support ingredients. Trainees in cut phases often stack CLA, L-carnitine and green tea separately - this formula consolidates those into the daily protein shake without requiring extra purchases. The 20g protein at just 101 calories keeps the macro hit lean while delivering the diet-support layer.

Diet Whey 1.8kg suits trainees in committed cut phases, lifters managing calorie-controlled diets where every gram counts, and anyone who would otherwise buy CLA, L-carnitine and green tea separately. It is not the right pick for hard-gainers in mass-building phases (the calorie-load is intentionally low). Contains milk, soy and gluten.

Higher-protein alternative: Applied Nutrition Critical Whey 2.2kg delivers 24g protein at 130 calories per 33g scoop - faster-absorbing daily-driver whey without the diet-support layer.

Frequently Asked Questions

How much PROTEIN is in each serving of Diet Whey Protein?

Each serving of Diet Whey Protein declares 20g of protein on the label. The full label is published on this product page so you can cross-check before stacking it with anything else.

When should I take Diet Whey Protein?

Diet Whey Protein is best taken within an hour of training, or as a between-meal protein top-up. Consistent use over time tends to do more than precise timing, so build it into a daily routine and let the habit do the work. Pair it with a balanced diet and a structured training plan, since supplements deliver against an existing stack, not on their own.

Is Diet Whey Protein third-party tested?

Diet Whey Protein is manufactured by Applied Nutrition in their UK facility. Many Applied Nutrition ranges carry Informed Sport batch testing for banned substances, so check the on-pack badge if Informed Sport status matters for your federation. The full ingredient breakdown and allergen disclosure is published on this product page, so you can review what is on the label before adding it to your stack.
