Which lifestyle program should you join?

From our perspective, you have two options:

  1. If you want to count calories, track your food intake, weigh your macros, lose weight fast and have a higher risk of weight regain, you can consider MyFitnessPal or Lose It! We think Lose It! might be the better choice as they seem to have more evidence-based resources available to support healthy choices. They also have a better Trustpilot score.
  2. Suppose you’d like to lose weight sustainably, be supported by a UK-registered dietitian or nutritionist, be free of the yo-yo dieting cycle, and follow a programme trusted by the NHS and backed by scientific evidence published in the British Medical Journal. In that case, Second Nature might be the better choice.

When we feel out of control with unhealthy habits, extra support can help us to get back on track. Guided lifestyle programs and food-tracking apps are some ways we can achieve this.

Everyone is different, and there isn’t a one-size-fits-all approach to choosing a lifestyle program or app.

It ultimately depends on what suits your individual needs and what fits into your lifestyle.

For example, lifestyle program can be a great way to join individuals going on the same journey, which can be incredibly motivating.

Other people may be looking for a more independent approach with less emphasis on support and accountability.

Many people turn to online weight loss solutions as they find them more convenient and easier to fit into daily life.

How do they work?

Both plans focus on counting calories. The apps help track your food intake to stay below a certain threshold based on your weight and goals.

Similarly, MyFitnessPal and Lose It! offer free versions of their app with limited features. This guide considers the features that are available in the premium versions.

MyFitnessPal and Lose It! are unguided programmes, so no one can answer your questions or provide nutritional advice.

At Second Nature, you’re assigned a health coach who is a registered nutritionist or dietitian.

This means they have completed university-accredited degrees to gain this professional title.

You’ll have one-to-one private support with your health coach for expert advice, support, or just a little motivation when you hit a bump in the road.

Instead, they rely on computer-generated replies from an existing knowledge base of blogs and FAQs.

Although calorie counting works for some people, the evidence suggests that not all calories are the same and shouldn’t be viewed as equal energy sources. You may find that a more holistic approach suits you better.

The risks of calorie-counting and strict dieting

Strict calorie restriction risks putting your body into what’s known as ‘metabolic adaptation’. This is essentially a starvation response by your body when energy intake is very low.

This triggers a cascade of events designed to encourage you to eat more and continue to store fat. You might feel lethargic and hungry, and your mood might also experience a dip.

Because of this starvation response to strict dieting, Second Nature has taken a different approach – one where you determine what level of intake works for you, and surprisingly, it can lead to more weight loss in the long term.

Second Nature’s approach: Indulgent but supports weight loss 

In 2022, the NHS published data in the British Medical Journal from the National Weight Management and Diabetes Prevention programme, where five providers delivered weight loss services in the UK.

The results showed that after 12 months, Second Nature was more than twice as effective as the four other providers.

How does Second Nature’s approach work?

We approach nutrition and healthy eating differently. We don’t count calories, track macros, weigh food, or assign strict targets on your intake.

We provide you with evidence-based guidance on a balanced diet and teach you to understand what your physical and emotional drivers for eating are to reach your weight loss goals.

We also provide tools, such as our hunger scale and mindful eating techniques, that help you tune into your physical hunger cues and manage your food choices.

Alongside this, we help you build healthy habits that you can enjoy for a lifetime to help you maintain a healthy weight.

Our feedback inbox is filled with people like Jo, who lost over eight stone to achieve a healthy body weight on Second Nature after following our nutrition guidelines and receiving the support of our app and health coaches.

The difference is that members of Second Nature learn to love food again. They’re no longer restricted. They’re liberated.

When programmes provide price plans in different formats, it can be hard to compare prices accurately.

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 April 2022).

MyFitnessPal and Lose It! have a lower membership fee than Second Nature.

However, Second Nature is the only programme that gives you private access to a registered dietitian or nutritionist and telephone support options.

Both MyFitnessPal and Lose It! do not offer a coach option. They are purely food-tracking apps.

Personalised support can help with accountability and tailoring a programme to your lifestyle and personal preferences. This extra support can be crucial to making lasting changes to your health.

Another option that offers high levels of personalisation and support is seeing a registered nutritionist or dietitian.

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 expensive ($40-$100/hour).

We have added a column representing this to compare costs (Weekly Nutritionist – WN).

Example nutrition query response

Nutrition is a significant part of any weight loss journey. Therefore, it’s essential 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?

It’s important to note that MyFitnessPal and Lose It! answers are computer generated. MyFitnessPal and Lose It! don’t answer your direct question but link you to an article within their knowledge base, which is shared below.

MyFitnessPal’s answer:

“Protein is found in various foods: meat, poultry, fish, dairy, eggs, legumes, nuts, seeds, soy and even grains.

From a dietary perspective, meats, poultry, fish, eggs, and soybeans are complete proteins; that is, they provide all of the amino acids required by our body.

Other protein foods like legumes, some nuts and seeds, and grains don’t provide adequate amounts of the essential amino acids by themselves but can when eaten in combination with other foods and as part of a balanced diet.”

The full article on Protein by MyFitnessPal can be read here.

Lose It!’s’ answer:

“We found this answer.
Macronutrient Recommendations. The Institute of Medicine recommends the following calorie breakdown:

45%-65% of daily calories should come from Carbohydrates
10%-35% of daily calories should come from Protein
20%-35% of daily calories should come from Fats”

The suggested article can be found here.

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 is not the case, as dietary cholesterol is poorly absorbed from the digestive system. If cholesterol is absorbed, the body will produce less to balance out (and prevent blood cholesterol levels from rising).

Therefore, you do not need to be restricted unless recommended to do so by your GP/Healthcare professional. Eggs are among the most nutritious foods on the planet, providing good quality protein and containing vitamins and minerals.”
