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 weight loss programme. It ultimately depends on what suits your individual needs and what fits into your lifestyle. Some people want rigid rules and a quick fix, whereas others like more flexibility and a long-term lifestyle change.
To save you tiresome research and help to answer some important questions, this guide compares two popular weight loss programmes; Slimming World® (SW) and Joe Wicks’ (a.k.a The Body Coach) plan (JW). You have the choice of face-to-face meetings or online plans with Slimming World®, whereas Joe Wicks’ 90-day plan is an online PDF that you can download.
Comparisons to the Second Nature programme are included. Second Nature is a digital programme that helps people lose weight in a healthy, sustainable way, by combining tracking technology with education and support.

Pricing
When programmes 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 digital basic price plans on each programme to show you how costs compare (as of March 2021). All admin fees are included in these prices.
For basic monthly plans, Joe Wicks®’ 90-day plan is the most expensive option. On the surface, Second Nature seems slightly more expensive than Slimming World®, however, your personal coach is a registered dietitian or nutritionist, rather than a customer service representative. You also have the same coach throughout the whole Second Nature programme that you can build a relationship with, rather than an ad-hoc response from a different coach each time (Slimming World® and Joe Wicks®).
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 (£40-£100/hour). We have added a column representing this to compare costs (Weekly Nutritionist – WN).

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?
Slimming World®’s answer:
“I’m not trained in medical queries I’m afraid, this would be something to ask your Health Care team.”
Joe Wicks®’ answer:
“Eggs are not bad but avoid them if you are worried.”
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.”
