The Man Shake VS The Lady Shake

The Man Shake and The Lady Shake are meal replacement products made and marketed by Cranky Health, a NSW company founded by Adam MacDougall. Adam “Mad Dog” MacDougall is a former League player (Knights, Roosters, and Rabbitohs) and the face of The Man Shake. His wife Belinda heads up The Lady Shake. What’s the difference between these two shakes?

What exactly is a Meal Replacement Shake?

A meal replacement shake is a drink designed to substitute a solid meal. Why would you want to substitute a solid plate of food with a glass of liquid? There are two main reasons: controlled nutrition and convenience. The controlled nutrition comes by formulating a specific combination of macro and micro nutrients in powder form. The convenience comes from the ease of scooping the powder into a container and shaking it up with water.

Meal Replacement for Weight Loss

Both The Man Shake and The Lady Shake are designed to replace one or two regular meals per day, for the purpose of controlling calorie intake. Weight loss is promoted because the shakes have much lower calories (209-204 calories per serve) than most regular meals. Since Calorie is King, a person substituting the shakes for meals will lose weight. The shakes have a high protein (about 50g/100g) and dietary fibre (10+g/100g) content, which help to reduce the feeling of having skipped a meal.

Evidence says they Work

Many studies show that meal replacement shakes work. Scientific peer-reviewed studies aside, just about everyone knows someone who has tried them with success. There are endless “before and after” photos on the internet showing how normal people make progress with meal replacement shakes. From a simple calories in/calories out (thermodynamics) basis, they have to work!

Lady Shake Calories

Man Shake VS Lady Shake Calories

The Man Shake has 209 calories (871kJ) per serve whilst The Lady Shake has 204 calories (853kJ) per serve. If you replace two meals with shakes, your daily calorie count before your main meal and snacks would be 408-418 calories. That gives you a 1,100 calorie window if you are trying to hit a 1500 calorie target.

Man Shake Calories

Man Shake VS Lady Shake Protein

Both The Man Shake and The Lady Shake are high in protein, but The Man Shake has 7% more than The Lady Shake (53.5g/serve compared to 50g/serve). There are some good reasons to put lots of protein in a meal replacement shake. Protein is more filling than carbohydrates. The body of a person undergoing calorie restriction might be strained and stressed. In such situations, it is important for there to be a good supply of muscle repairing protein at hand. Finally, protein has fewer calories by weight than fat and it “burns” slower than carbs.

Man Shake VS Lady Shake Fat

It is a good idea for a meal replacement shake to have some fat, but not much. Fat is an essential nutrient with the highest calories. It satisfies the body’s hunger sensation like no other nutrient. Most effective meal replacement shakes include fat for these reasons, and The Lady Shake and the Man Shake are no exception. The Man Shake has more, with 7.1g fat per serve, compared to 4.5g/serve in The Lady Shake.

Man Shake VS Lady Shake Carbohydrates

In terms of macros, carbohydrates are the real differentiation point between The Man Shake and The Lady Shake. The Lady Shake has 28.8g carbs per serve, compared to 20g carbs in a serve of The Man Shake. Effectively, The Lady Shake has 44% more carbohydrates than The Man Shake. Why is this? Probably because men, with more muscle mass than women, require more protein. Since their formulation has more protein, they have do make do with less carbs in order to hit the 200 calorie/serve target. Maybe? We’re not sure.

Sugar in The Man Shake and The Lady Shake

With 44% more carbs than The Man Shake, you would probably think that The Lady Shake has much more sugar too? The Lady Shake has 8.7g sugar per serve, compared to 9.4g sugar in a serve of The Man Shake. That’s right, The Lady Shake has less sugar than The Man Shake! On the nutrition label of both products, they’ve separated the sugars into “sugars, Lactose, Galactose” categories, so you need to add them up to get the total sugar values.

Lady Shake Nutrition


Both The Man Shake and The Lady Shake are jam-packed with micronutrients (vitamins and minerals). You would not be too far wrong in thinking about them as having half of a typical multivitamin capsule mixed in with the other ingredients. If you are familiar with vitamin and mineral supplements, you probably know that they are often separately formulated for men and women according to their typical needs. A key difference between The Man Shake and The Lady Shake is that their micronutrients follow the same principle. Lots more zinc in The Man Shake, way more Folate in The Lady Shake, and so on.

Can a Man drink The Lady Shake Safely?

Yes, a man can safely drink The Lady Shake without any negative repercussions. They’re formulated to work best for the general requirements of the genders they are targeted to, but there is nothing harmful in either of them. Guys, if there is a pack of The Lady Shake in the pantry and you need a drinkable meal, don’t hold back!

Can a Lady take The Man Shake?

Since there are no hormones in either The Man Shake nor The Lady Shake, it is perfectly safe for a lady to take The Man Shake. In the absence of The Lady Shake, a lady can drink a Man Shake without concern. However, The Man Shake has a balance of micronutrients which are skewed towards men’s health and wellbeing.

Meal Replacement Shakes

Should you Use Them?

Meal replacement shakes like The Lady Shake and The Man Shake do help with weight loss, it is incontrovertible. In the vast majority of cases, people who substitute their usual meals for low calorie shakes will hit their calorie deficit threshold. However, they should not be used to replace more than two meals per day. Ideally, a normal meal and a normal snack should be eaten in addition to two meal replacement shakes every day. Of course, they will not work if you eat extra food to compensate for the reduced calories!
