Weight Loss Programmes

The 1:1 Diet by Cambridge Weight Plan vs LighterLife

title

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.

Many people find online weight loss programmes more convenient and easier to fit into daily life. To save you tiresome research and help to answer some important questions, this guide compares three popular online weight loss programmes; The 1:1 Diet by Cambridge Weight Plan, LighterLife, and Second Nature.

Both The 1:1 Diet by Cambridge Weight Plan and LighterLife are very-low calorie diets (VLCD) use meal replacements to achieve results. We would recommend consulting a doctor before starting these programmes.

The Second Nature programme takes a lower-carb approach, and focuses on food education for sustainable results. At Second Nature all the health coaches are registered nutritionists or dietitians. This means they have completed university accredited degrees to gain this professional title. You’ll have a private chat with your health coach for expert advice, support, or just a little motivation when you hit a bump in the road.

The 1:1 Diet by Cambridge Weight Plan and LighterLife consultants are people who’ve previously taken the programme and want to help others through the same experience.

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 basic price plans on each programme to show you how costs compare (as of January 2021).

The 1:1 Diet by Cambridge Weight Plan pricing is estimated, based on three replacement meals a day and LighterLife is based on 4 food packs a day and no conventional food. It’s best to discuss pricing based on your needs before starting the programme as this may vary.

All programmes provide you access to a coach throughout the programme to support and encourage you. A key difference between the programmes is that Second Nature’s coaches are registered nutritionists or dietitians, rather than previous members (The 1:1 Diet by Cambridge Weight Plan and LighterLife).

Only Second Nature includes access to a private chat to a registered dietitian or nutritionist who will be with you every step of the journey.

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?

The 1:1 Diet by Cambridge Weight Plan’s answer:

““We at head office are not trained as dieticians and cannot give out specific information on the benefit of eggs for your diet, but if you do have concerns about your cholesterol we would advise you to seek a medical opinion concerning your whole diet and the food groups you should look at avoiding.”

LighterLife’s Answer:

“That isn’t something we can advise you on I’m afraid. On our Total plan you would have 4 Foodpacks a day and no conventional food. We do have a structured Management plan for food reintroduction so we advise what foods to introduce, when to introduce them and the quantities. For information on cholesterol you can look online. I’m sure there is lots of information out there for your specific question.”

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.”
