Weight loss programs can provide a helpful structure for your health journey when you feel out of control with unhealthy habits. They can also be a great way to join individuals going on the same journey, which can be incredibly motivating

Everyone is different, and there is not a one-size-fits-all approach to choosing a weight loss program. It ultimately depends on what suits your individual needs and what fits into your lifestyle.

Many people find online weight loss programs more convenient and easier to fit into daily life. To save you some tiresome research and help to answer some important questions, this guide compares two popular weight loss programs: The Lady Shake and Second Nature.

The Lady Shake and Second Nature are both marketed towards weight loss. However, their approach differs considerably. Second Nature is a 12-week online program that focuses on holistic lifestyle changes (nutrition, exercise, mindset, sleep, stress). Daily support and personalised support is offered from a qualified dietitian which ensures advice is tailored to the unique nutrition requirements of each individual. In contrast, The Lady Shake solely addresses nutrition by offering a generic two-week nutrition plan. This plan is created by a dietitian however no further support is offered to personalise this plan to each individual. 

Another notable difference between the programs is that Second Nature encourages a whole food approach and recommends obtaining nutrients from whole foods. The Lady Shake focuses on meal replacements and encourages the consumption of two meal replacement shakes per day, two snacks (such as their patented protein bars and pre-made milk drinks), and one food-based meal.

When programs provide price plans in different formats, it can be hard to accurately compare prices. To make this easier, we have calculated the price of monthly basic price plans on each program to show you how costs compare over 3, 6, and 12 months (as of July 2021). All admin fees are included in these prices.

It’s worth noting that all Second Nature health coaches are Accredited Practising Dietitians and members receive personalised support on a daily basis. The Lady Shake offer ad hoc support via their customer support team however, nutrition qualifications aren’t disclosed. 

Registration to a professional body requires a nationally recognised nutrition or dietetics degree. Weekly face-to-face sessions with an APD can be very expensive ($100+/hour). We have added a column representing this to compare the Weekly Dietitian costs.

Monthly (basic) digital subscriptions:

The Lady Shake Second Nature Weekly Nutritionist
Registered dietitian or nutritionist coach
The same, personal coach throughout the programme
Price $134.95 / month* $75 / month $440 / month

*Monthly cost is based on consuming two protein shakes per day. However, this cost does increase if other products (e.g. The Lady Bar, Chocolate Super Greens) are purchased.

Example nutrition query response

Nutrition is a major part of any weight loss journey. Therefore, it is important to receive accurate and reliable nutrition advice. We asked each program a common nutrition-related query to see how the information provided as an answer compares.

Q: Are eggs bad for your cholesterol? Should I avoid them?

The Man Shake’s answer:

“If you are concerned about your cholesterol, it’s probably best to check this with your GP.”

Second Nature’s answer:

“Eggs are a rich source of dietary cholesterol. It was previously thought that cholesterol-containing foods increase blood cholesterol and the risk of heart disease and strokes. However, this has not been shown to be the case as dietary cholesterol is poorly absorbed from the digestive system, and if cholesterol is absorbed, the body will produce less of it to balance out (and prevent blood cholesterol levels rising). Therefore, you do not need to be restricted unless recommended to do so from your GP/Healthcare professional. Eggs are among the most nutritious foods on the planet providing good quality protein as well as being loaded with vitamins and minerals.”

Take home message

  • When choosing a weight loss program, it is important to consider what would fit into your lifestyle and help you achieve your goals.
  • For those who find face-to-face weight loss meetings uncomfortable or inconvenient, online and digitally led programs are a better option.
  • Second Nature is a 12-week online program that focuses on holistic lifestyle changes and provides you with an education of nutrition science. The Lady Shake, however, only addresses nutrition.
  • Second Nature encourages a whole food approach, while The Lady Shake encourages the consumption of two meal replacement shakes per day, two snacks (such as their patented protein bars and pre-made milk drinks), and one food-based meal.
  • Second Nature provides members with daily personalised advice around nutrition and lifestyle from their personal Accredited Practising Dietitian, whereas The Lady Shake is a self-led program with ad-hoc support from a customer support team.
  • The Lady Shake has a locally based customer support team who provide ad hoc nutrition support. Second Nature also has a team of health coaches in Australia and New Zealand. However, support and advice is provided daily, which helps to guide you along each part of the program.
