What is Diet Shake by BiotechUSA?
Diet Shake is BiotechUSA's flagship weight management protein shake, combining high-quality whey protein concentrate with six different dietary fibre sources, L-carnitine, bromelain enzyme, chromium, calcium and a selection of superfoods — all in a single 30g serving delivering a maximum of 110 kcal when mixed with water. It is designed for individuals who want to supplement their diet with a nutritious, filling and genuinely delicious low-calorie protein meal, without resorting to empty calories or overly restrictive eating.
The formula's nutritional architecture is deliberately layered. At its core is instant whey protein concentrate (61 to 69% of the formula depending on flavour), providing a high-quality complete protein to support muscle mass maintenance during caloric restriction — the primary physiological challenge of any weight management protocol. Around this protein foundation, six distinct dietary fibre sources create a satiety effect that outlasts the serving itself: glucomannan (1050mg), inulin (2700mg), oat flakes flour, citrus fibre, flax seed powder and psyllium husks powder each contribute distinct fibre types and textures, creating a broad-spectrum fibre matrix that delays gastric emptying, feeds beneficial gut bacteria and helps manage appetite between meals.
L-carnitine L-tartrate (320mg, providing 220mg of L-carnitine) supports fatty acid transport during exercise. Bromelain from pineapple (160mg, 1200 GDU/g) is a protein-digesting enzyme that supports protein absorption and contributes to the product's digestive comfort. Chromium (18µg, 150% NRV per serving) contributes to the maintenance of normal blood glucose levels and to the normal metabolism of macronutrients — both directly relevant to appetite and energy management. Acai berry and goji berry powders add antioxidant superfood credentials.
Available in 720g (24 servings) across five flavours: Chocolate, Pistachio, Strawberry, Vanilla and Cookies & Cream. Palm oil free, low fat, low sugar, GMO-free.
Protein. Fibre. Superfoods. The complete diet shake.

How Diet Shake by BiotechUSA supports your objectives
💪 15 to 16g of protein for muscle mass maintenance during dieting Protein contributes to the maintenance of muscle mass and to its growth. During caloric restriction, the body's tendency to catabolise lean muscle alongside fat makes adequate protein intake the single most important nutritional factor for body composition outcomes. Each 30g serving of Diet Shake provides 15 to 16g of high-quality whey protein — a meaningful contribution toward daily protein targets that supports the preservation of lean tissue throughout the weight management journey.
🌿 6 dietary fibre sources — satiety and digestive health from every angle Diet Shake is genuinely unusual in providing not one or two fibre sources, but six distinct types: glucomannan from konjac tuber (a highly water-absorbent fibre that forms a gel in the stomach, dramatically slowing gastric emptying), inulin (a prebiotic fructooligosaccharide that feeds beneficial gut bacteria), oat flakes flour (beta-glucan-rich soluble fibre), citrus fibre (water-soluble and thickening), flax seed powder (omega-3-rich with soluble and insoluble fibre fractions) and psyllium husks powder (one of the most water-absorbent fibres available). Together, they create a satiety effect that extends well beyond the 30g serving.
⚡ Chromium (18µg, 150% NRV) for normal blood sugar regulation Chromium contributes to the maintenance of normal blood glucose levels and to the normal metabolism of macronutrients. In the context of a weight management shake, chromium's blood sugar-stabilising function is directly relevant: stable blood glucose reduces the energy crashes and carbohydrate cravings that derail dietary adherence. At 150% of the NRV per serving, the chromium dose in Diet Shake provides meaningful daily chromium supplementation.
🍍 Bromelain enzyme for protein digestion support Bromelain is a protein-digesting enzyme found naturally in pineapple. Its inclusion in Diet Shake at 160mg (1200 GDU/g activity) ensures that the whey protein matrix is efficiently digested and absorbed, minimising any digestive discomfort associated with high protein intake. Bromelain also has anti-inflammatory properties that may support recovery in active individuals.
🌟 Acai berry and goji berry powders — superfood antioxidant support Each serving contains 0.6% acai berry powder and 0.6% goji berry powder — two of the most antioxidant-dense botanical foods available. These superfood additions contribute polyphenols, anthocyanins, vitamins and trace minerals to the formula's nutritional profile, reflecting the product's positioning as a complete dietary supplement rather than a simple protein powder.
🎯 Goal guide
🏋️ Mass gain: Not the primary use case. Lower caloric density than dedicated gainers.
🔥 Weight loss / cutting: 1 serving/day replacing a meal or snack. Max 110 kcal in water — the primary use case.
⚖️ Body recomposition: 1 serving/day. High protein, high fibre, low calorie — ideal for controlled body composition management.
Serving suggestion
Mix 1 serving (30g = 4 level tablespoons) with 300ml of cold water in a shaker bottle. Shake well until fully dissolved. Consume once per day. Can also be prepared with cold milk for a creamier texture and higher protein content. Not recommended as the sole source of daily nutrition — use as part of a varied and balanced diet.
Best times to enjoy it
🌅 As a breakfast replacement For individuals with busy morning schedules, Diet Shake provides a complete nutritional profile in under 2 minutes of preparation — protein, fibre, chromium, L-carnitine and superfoods in a single serving, at maximum 110 kcal in water.
🍽️ As a lunch or dinner replacement Replacing one meal per day with Diet Shake is the most commonly used protocol for gradual, sustainable weight management. The glucomannan and inulin fibre content creates a prolonged feeling of fullness that makes the meal substitution genuinely satisfying rather than simply restrictive.
☀️ As a mid-morning or afternoon snack Between-meal consumption of Diet Shake addresses the hunger and cravings that typically derail dietary adherence during caloric restriction, providing protein and fibre-driven satiety at minimal caloric cost.
🏋️ Before or after training The whey protein content makes Diet Shake a practical pre or post-workout protein source for athletes who train during a weight management phase. The L-carnitine content adds a pre-workout fat metabolism support dimension.
Daily protein target reminder
Current sports nutrition science recommends 1.6 to 2.2g of protein per kg of body weight per day for active individuals. Each serving of Diet Shake contributes 15 to 16g toward this daily target. For vegan athletes, targeting the upper end (1.8 to 2.2g/kg) is advised.
| Body weight | Min. target (1.6g/kg) | Max. target (2.2g/kg) | Servings needed* |
|---|---|---|---|
| 55 kg | 88g/day | 121g/day | 1 serving covers 15-16g |
| 65 kg | 104g/day | 143g/day | 1 serving covers 15-16g |
| 75 kg | 120g/day | 165g/day | 1 serving covers 15-16g |
| 85 kg | 136g/day | 187g/day | 1 serving covers 15-16g |
| 95 kg | 152g/day | 209g/day | 1 serving covers 15-16g |
*Diet Shake is typically used as one serving per day alongside a complete balanced diet.
Goal-specific guidance
For weight loss: Use Diet Shake to replace one meal per day — typically the meal where dietary adherence is most difficult (often breakfast or dinner). Combine with 3 to 4 balanced whole-food meals providing complete micronutrition. The maximum 110 kcal per serving (in water) allows Diet Shake to fit into even very restricted caloric budgets. Pair with a structured exercise programme for optimal body composition outcomes — the product itself does not cause weight loss, but makes caloric restriction significantly more manageable.
For body recomposition: Use Diet Shake as a controlled-calorie protein source during a maintenance-calorie diet alongside progressive resistance training. The high protein and fibre content supports lean mass preservation while the chromium and L-carnitine contribute to metabolic efficiency and fat utilisation during exercise.
🏅 Sport Nutrition "Did you know?"
Glucomannan — one of the six fibre sources in Diet Shake and arguably the most powerful — is the only food supplement ingredient that carries an EU-authorised health claim for weight management: "Glucomannan in the context of an energy-restricted diet contributes to weight loss." This claim requires a minimum of 1g of glucomannan per serving, taken with adequate water before a meal. Diet Shake delivers 1050mg (1.05g) of glucomannan per serving — just above this threshold. The mechanism is simple but physiologically powerful: glucomannan absorbs up to 50 times its own weight in water, forming a thick gel in the stomach that physically occupies space, dramatically slows digestion and produces a prolonged satiety effect that reduces caloric intake at subsequent meals.

Q1 — How is Diet Shake different from a regular protein powder? Diet Shake goes significantly beyond a standard protein powder in three ways. First, it contains six distinct dietary fibre sources (glucomannan, inulin, oat flour, citrus fibre, flax seed, psyllium husks) that create a prolonged satiety effect after each serving. Second, it includes functional actives specifically relevant to weight management: L-carnitine (fatty acid transport), chromium (blood glucose regulation), bromelain (protein digestion) and superfoods. Third, at a maximum of 110 kcal per 30g serving with water, it is specifically calibrated for low-calorie dietary contexts — where a standard protein powder might provide 120 to 150 kcal from protein alone.
Q2 — Can Diet Shake replace a full meal? Yes, as a supplement to a varied and balanced diet. Diet Shake is designed to be used as a meal replacement for one meal per day — providing protein, fibre, minerals and functional actives in a convenient format at maximum 110 kcal. However, it cannot provide the full micronutrient spectrum of a whole-food meal, and should not be used as the sole source of daily nutrition. The product does not replace a varied and balanced diet and a healthy lifestyle.
Q3 — Does the Cookies & Cream variant contain caffeine? Yes, in trace amounts. The Cookies & Cream variant's ingredient list includes flavourings that contain caffeine. The quantity is not declared on the product page and is likely very small (from the flavouring system rather than added caffeine). Athletes who are highly caffeine-sensitive or who consume other caffeine sources throughout the day should be aware of this declaration. All other four variants (Chocolate, Pistachio, Strawberry, Vanilla) do not list caffeine in their ingredient declarations.
Q4 — Can I mix Diet Shake with milk instead of water? Yes, and many customers prefer the creamier texture that results from mixing with cold semi-skimmed or skimmed milk. Using 300ml of semi-skimmed milk instead of water adds approximately 100 kcal, 10g of carbohydrates, 5g of protein and additional calcium to the serving. For individuals who are not tracking calories strictly, milk-prepared Diet Shake is more satisfying and has a significantly better texture. For those in a strict caloric deficit, water preparation at maximum 110 kcal is the standard protocol.
Q5 — How many servings does the 720g bag provide? At 30g per serving, the 720g bag provides exactly 24 servings. At one serving per day, this represents approximately 3.5 weeks (24 days) of use. For regular daily users, purchasing in advance or keeping a spare bag ensures the supplementation protocol is never interrupted during critical phases of a weight management programme.
