JS Health App vs Second Nature

Weight loss programmes 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 health 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 tiresome research and help to answer some important questions, this guide compares two popular online weight loss programs; the JS Health App and Second Nature.

JS Health program and Second Nature focus on behaviour change and take a holistic view of health by addressing sleep, stress and mindset and nutrition. Both programs encourage whole foods and mindful eating. JS Health also encourages the use of supplements which can be an unnecessary cost for some people.

One of the main differences between the programs is that Second Nature offers daily guidance from a dedicated and qualified health coach, alongside peer support from members on the programme. The JS Health app provides a nutritionist to answer questions, but no personalised support is given throughout the program.

Second Nature is also scientifically-designed for weight loss, whereas the advice offered by the JSHealth app is based on the ‘JSHealth philosophy’. This philosophy is based on the founder’s own healthy journey and revolves around ‘eating a nutritionally balanced diet and establishing equilibrium for mind, body and soul’.

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 February 2021). All admin fees are included in these prices.

On the surface, Second Nature seems slightly more expensive, however, this is because you are assigned a qualified health coach who is a registered dietitian, rather than a previous program member or customer service representative.

Your health coach provides daily support to your and your group, helping guide you along each part of the program. You also have the same health coach throughout the whole Second Nature journey that you can build a relationship with, rather than an ad-hoc response from a different coach each time.

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

Price $9.99* $75/month $400/month

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 programme 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?

JS Health App’s answer:

“Eggs are naturally high in HDL (the good cholesterol) and don’t raise cholesterol levels the same way that other cholesterol-containing foods do. We recommend enjoying an average of 2 eggs a day if you like. They are a great source of protein, quality fats and choline.”

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 health program, it is important to consider what would fit into your lifestyle and help you achieve your goals.
  • JSHealth app and Second Nature are both fully available online.
  • JSHealth encourages purchasing multiple supplements which can be costly and unrealistic for some people.
  • Second Nature provides a registered dietitian or nutritionist personal health coach who supports you for the duration of the program, providing specific advice based on your personal circumstances. Whereas JS Health provides a nutrition coach who can only provide generalised support and advice.
  • Second Nature provides you with an education of nutrition science, allowing you to make informed decisions yourself and develop a healthy relationship with food in the long-term. JS Health offers advice based on the ‘JSHealth philosophy’ rather than nutrition science.
