  1. Can Shape be used to gain weight/muscle?

Answer: Shape Diet shake is designed for weight loss and management and it is used to replace a meal.

Meal replacements can simplify weight loss regimens by replacing one or two meals a day with a product that has a defined nutrient and calorie content.1A

Moderate to high protein meal replacements may increase feelings of satiety and favour the reduction of energy intake in other meals eaten in the day.1B

Several health professionals currently recommend the use of meal replacement products, and these are used increasingly in weight loss studies.1C

Meal replacements products have also shown to help with compliance to weight reduction programmes and weight management.[1]D

  • Is Shape high in protein? Is Shape a protein shake?

Answer:  Shape contains 12.5-12.6g of protein per shake. This equates to 25.3 to 25.8% of the total energy.

Standard diets usually provide 10-15% of protein per meal.1E, 1G Therefore, Shape is considered a high protein product.

Diets higher in protein (>/= 25%) have shown to be more satisfying and therefore make you feel fuller for longer and prevent you from eating too much at your other meals in the day.1B,[2]A

Additionally, higher protein diets can improve adherence to the diet, retain lean body mass (muscle), improve insulin regulation, reduce triglycerides and protect energy expenditure (metabolism).1F

  • How many kJ does Shape have per serving and what does this equate to?

Answer:  Shape provides 831kJ (chocolate flavour) to 841kJ (strawberry and vanilla flavour) per serving when made up with water. This is equal to:

3 tablespoons raw oats (32g)562.24kJ
¼ cup (62.5ml) Low fat milk130kJ
½ large boiled egg159.25kJ
Total kilojoules per meal851.49kJ


1 slice wholewheat bread372KJ
½ can of tuna in water (60g drained)292.2kJ
1 level teaspoon (5g) 50% polyunsaturated margarine150.35kJ
Total kilojoules per meal814.55kJ


½ cup cooked brown rice324.8kJ
45g cooked chicken breast324.9kJ
½ cup cooked Broccoli88.5kJ
½ cup baby carrots, steamed141kJ
Total kilojoules per meal879.2KJ

Comparison meals are calculated by a registered dietician using the MRC Food Quantities manual and the Food composition tables (1991).

  • Is Shape safe for use in diabetics?

Answer: It is universally accepted that dietary carbohydrate is the main dietary determinant of blood glucose and monitoring and regulating carbohydrate intake shows the greatest reduction on post meal and overall glucose control.[3]A, 4A

Both the source and the amount of carbohydrate in a food will influence its effect on blood glucose level.[4]B Lactose and maltodextrin are the carbohydrate sources in Shape.  Shape does not contain sucrose. Shape provides 21.8-24g of carbohydrates per shake when mixed with water.

It is recommended that if you have diabetes you should consult with your health professional regarding your specific carbohydrate needs.

Shape contains a sugar replacement called sucralose. The safety of sucralose has been extensively evaluated by regulatory agencies around the world, and it is approved globally for use in foods and beverages as a non-caloric sweetener.5A Most ingested sucralose is excreted unchanged in the faeces, meaning that there is no build up in the body with long term use.5B Sucralose is not digested or metabolised for energy as it is not absorbed into the blood stream. Therefore, no calories are obtained from sucralose, and sucralose does not affect blood sugars. These properties result in the use of sucralose to produce foods and beverages that are suitable for persons with diabetes or those aiming to reduce calorie or carbohydrate intake.5C

  • If I am lactose intolerant, can I use Shape products?

Answer: Shape shakes contain skim milk powder which contains lactose

  • Can Shape cause digestive problems including constipation and diarrhoea?

Answer: If you are lactose intolerant you may have digestive problems with Shape shakes as it does contain lactose.

Sucralose has no effect on gut hormones and/or gut function.6A,6C The acceptable dietary intake (ADI) is limited to 5mg/kg/day by the Food and Drug Administration (FDA).6B

  • Will there be side effects if I consume too much of the Shape shakes?

Answer:  It is recommended that you take one shake to replace one meal and you can replace up to 3 meals a day. Taking more than this will mean that you may not achieve the weight loss results that you want. 

There are no ingredients in Shape that should cause gastro-intestinal side effects. However, sucralose may cause gastro intestinal symptoms if you take more than recommended 5mg/kg/day.6B,6D

  • How do the Shape shakes compare to a low-fat or high fat meal?

Answer: Per serving, Shape shakes contain 831-841kJ; 12.5-12.6g of protein (25% of total energy); 21.8-24g carbohydrate (46% of total energy); and 6.6-7.2g fat (29% of total energy).

Standard (low fat) diets contain 15% protein, 55-55% carbohydrates, and <30% fat.1G

Comparatively, Shape shakes are lower in fat but higher in protein and lower in carbohydrate than a standard diet. A diet higher in protein has shown to lower appetite by keeping you satisfied for longer.1B,2A

Let’s compare a low fat and high fat meal to the shape shake:

A low-fat breakfast:

 ProteinFatCarbohydrate(Energy) kJ
1 cup bran flakes6.35g0.65g28.75g519kJ
200ml low fat milk6.63.8g9.6g416kJ
Total meal12.95g (23.5%)4.45g (18%)38.35g (59%)935kJ

A high fat breakfast:

 ProteinFatCarbohydrate(Energy) kJ
1 rasher of bacon (10g)3.47g4.92g0241kJ
1 large egg, fried in oil6.97g5.13g0.6g318.5kJ
1 teaspoon olive oil05g0184.95kJ
1 slice wholewheat bread3.32g0.84g17.72g372kJ
Total meal13.76g (20%)15.89g (52%)18.32g (28%)1116.45kJ

This comparison shows that Shape has a better macronutrient profile compared to a low fat or high fat meal. Diets that are made up of 25% or more protein help you to feel satisfied helping you to eat less at other meals and thereby helping to lose weight.1B Research has also shown that replacing carbohydrate with protein is better for weight loss than replacing fat for protein.1H This means that when protein is at 25%, fat should be maintained at around 30%, and carbohydrate should be around 45%, which is what Shape shakes provide.

  • How many times a day can I drink Shape?

Answer:  You can replace any meal with one shake. You can replace one to three meals a day.

The problem with any weight loss diet is sustainability. Having 3 shakes a day instead of meals is difficult to sustain. Instead of going off the shakes completely, try using it for two or one meal instead and have a low kilojoule balanced meal when you are not having the shake.

  1. How long will it take me to lose weight using the Shape shakes?

Answer:    Shape shakes aid with weight loss because they should be lower in calories than meals you are currently eating. It will depend on your current intake as to how quickly you will lose weight. Weight loss will also depend on other lifestyle behaviours like exercise and the other foods you eat during the day.

Long-term negative energy balance is necessary for individuals who are overweight and obese to lose weight.7A.8A Energy-restricted meal replacements are a safe and effective strategy for weight control that has been implemented in many studies.7B

In order to lose ½ kg a week you need to eat 2100kJ a day less than you currently do.8B

The problem with any weight loss diet is sustainability. Having 3 shakes a day instead of meals is difficult to sustain. Instead of going off the shakes completely, try using it for two or one meal instead and have a low kilojoule balanced meal when you are not having the shake.

  1. Are the Shape shakes safe to use during pregnancy and breastfeeding?

Answer:   Shape shakes do not contain any ingredients that should be avoided in pregnancy or breastfeeding. However, weight loss is not advised in pregnancy, and calories restriction is not advisable during breastfeeding. Breastfeeding is energy consuming and breastfeeding mothers generally need more calories to meet their nutritional needs while breastfeeding. The CDC recommends an additional 2000 kilojoules a day.9

You can use Shape shakes as snacks to increase your intake but it should not be used to replace a meal or for intentional weight loss.

  1. Are the Shape shakes vegetarian and vegan friendly?

Answer: Shape shakes contain skim milk powder. Milk is vegetarian friendly but it is not allowed on a vegan diet.

  1. Are Shape shakes a suitable substitute for a balanced diet?

Answer:     Short-term Shape shakes can safely substitute all 3 meals of the day. You will need to include raw or cooked vegetables every day in order to meet the fibre requirements for the day.

  1. Can I or should I add fruit or other ingredients to Shape shakes?

Answer: It is not necessary to add fruit or other ingredients to the Shape shake.

The Shape shake only contains 0.2-1.3 of fibre per serving. It does not meet fibre requirements of 20-35g a day.10 Therefore, it is important to add raw or cooked vegetables, lentils or legumes, or berries every day. An easy way of getting some vegetables into your daily intake is to add it to your shake in a blender. For example, adding spinach, broccoli, or kale to the shake and have beans, raspberries or salad as snacks as they are packed full of fibre.10
