What are the common steps to lose weight?

Weight loss is possible through a variety of tried-and-true methods, whether you undergo medically-backed prescription treatments or take a holistic approach.

Food and diet

If you’ve asked yourself, ‘How can I lose weight without exercising?’ then the answer is that it depends on your diet.

Questions like  ‘What fruit is good for weight loss?‘ to  ‘What is good fat?’ often don’t take into account a key point, which is that each person’s body has its own needs and nutritional requirements. A weight loss protein shake that works for a peer or friend may not work for you, because you each have dietary needs that are different from the other.

With this in mind, our network of Australian doctors are more than happy to work with you on developing and tailoring a weight loss protein shake or diet that meets your requirements while also helping you lose or otherwise manage your weight.


Working out remains one of the most effective weight loss methods, and with good reason: staying active, even with low-impact workouts, goes a long way towards burning body fat.

Even the best protein shakes for weight loss need some help sometimes, which is where exercise comes in. If you’re curious about what exercise is best to lose weight, then a Mosh doctor may be able to help.

They can also answer any questions you may have about topics like ‘What is healthy fat?’ and how to trim or gain such types of fat, which can help you achieve your target weight.

Evidence-based treatments

Finally, some people may need medical treatment to help with their weight management plan, so rather than scratch your head over questions like ‘How much fat is in an egg?’ why not just ask your Mosh doctor? 

Mosh has a brief questionnaire that you can fill out to help us determine if such treatments are needed for your weight management plan. After we’ve received this form, we will connect you with an AHPRA-licenced doctor who will speak with you online for an initial meeting.

Should treatment be required, your Mosh health practitioner will walk you through your options.  To that end, Mosh can also recommend our best protein shakes for weight loss based on your medical requirements, as well as other options if necessary.

How do protein shakes help with weight loss?

Protein shakes are a dietary supplement that is popularly used in weight management plans.

As opposed to conventional foods, dietary supplements are intended to enhance a diet by providing any lacking nutrients or helping address any nutrient deficiencies that are affecting weight loss, weight gain, or weight maintenance.

Contrary to popular myth, protein shakes can be just as practical for weight loss as they are for weight gain, as their primary goal is to nourish.[1] Nutrient deficiency, consequently, can affect both weight loss and weight gain.[2]

What type of protein is best for losing weight?

The best protein shakes for weight loss typically feature several healthy proteins. Below are a few examples of these proteins. 

  • Whey protein. Whey is one of the more popular proteins when it comes to protein shakes. Taking whey protein supplements has been observed to reduce body weight, total fat mass, and certain cardiovascular disease risk factors.[3]
  • Soy protein. A low-energy diet containing soy protein shakes has been observed to aid weight loss.[4] In randomised crossover trials of overweight men who were on weight-loss diets featuring high soy protein content, heightened appetite control and weight loss were also observed.[5] This protein is a great alternative to milk proteins as well, especially for those on vegetarian or vegan diets.
  • Casein protein. Casein is a protein that can be found in dairy foods like milk, and is one of the more common proteins in our diet.[6] Low-fat, high-casein diets have been shown to be more effective when it comes to weight maintenance and control, making it an ideal protein for weight management diets.[7]

Depending on your weight loss treatment plan, you may be recommended to take any, all, or a combination of these or other proteins. Consult your Mosh doctor if you are interested in adding these proteins to your diet. They may also suggest our best protein shakes for weight loss or gain, depending on your weight goals.

How much weight can I lose on a protein shake diet?

Key among the factors involved in how to diet to lose belly fat is understanding the limitations of dietary supplements. That is to say, they’re most effective when paired with exercise and a healthy weight loss rate.

Ideally, a healthy adult Australian should lose between 0.5 and 1.0 kilograms per week.[8] This can be achieved by staying active, eating healthy, and practising a mindful lifestyle – after all, cortisol (also known as the stress hormone) can impact your weight loss negatively under certain circumstances.[9]
