Noom vs Weight Watchers | Weight Watchers Reviews | Noom Reviews (2024)

Which weight loss programme 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 Noom or WW. From our perspective, WW might be the better choice as you at least know what you’re getting from them. In comparison, Noom’s marketing is rarely replicated in its programme.
  2. Suppose you’d like to lose weight sustainably, be supported by a UK-registered dietitian or nutritionist, free yourself from 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.

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 no one-size-fits-all approach to choosing a weight management 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 some tiresome research and help to answer some crucial questions, this guide compares two popular weight loss programmes: Noom, WW, and Second Nature.

WW and Noom are calorie-counting programmes

WW (Weight Watchers Reimagined, formerly Weight WatchersⓇ) considers food, activity, sleep and mindset to help you lose weight.

The programme is based on the WW SmartPointⓇ system – a system where foods are ranked based on their calorie density and saturated fat content – and is available in either digital or face-to-face format.

On Noom, you’re assigned a ‘personal’ calorie target. However, it seems that everyone is assigned a 1200-calorie target, no matter what information you put into the Noom quiz.

Rather than a points system, Noom uses a colour coding system for foods based on their energy density. So, nuts might be in the red zone, while sugar-free jelly might be labelled green.

Counting calories and logging them in the app works well for some people. However, this can lead to obsessive tendencies and isn’t sustainable in the long term for others.

Is WW a strict crash diet?

WW claim its points system is a better approach than calorie counting and has no adverse psychological effects that people can experience when becoming obsessive about calorie counting.

However, dietitian, nutrition writer, and food psychology expert Abby Sharp delivered a scathing review of WWs new programme on YouTube titled “Dietitian Reviews Weight Watchers (YEP, IT’S STILL REALLY REALLY BAD)”.

You can watch the full video here, but here’s a quick summary of Abby’s analysis:

  • The new WW is “just expensive calorie counting”.
  • The points system on WW to create a ‘food budget’ is unnatural.
  • The ‘rolling over’ of points might mean people intentionally restrict themselves too much to then binge at the weekend.
  • WW promotes restriction and binging cycles common in people living with patterns of disordered eating.
  • WW demonises natural, healthy high-calorie foods like Brazil nuts. If you were to enjoy 28g of Brazil nuts, you’d use up half your SmartPoints for the day.
  • The points system doesn’t help you identify the quality of the foods you’re consuming. Instead, it mainly focuses on a reductionist approach to calorie density.

Noom may be another strict diet

Despite Noom’s advertising as a sustainable weight loss solution, and their programme containing some information on behavioural science, their approach to nutrition and other programme elements mimic many of the restrictive dieting approaches seen in Weight Watchers.

Dietitian and eating disorder expert Christine Byrne wrote a review on Noom for Outside magazine in 2021 and quoted:

“Don’t Be Fooled, Noom Is Just Another Diet.

The popular app promises weight loss without dieting. Then it proposes restrictive eating habits.

…behind Noom’s popularity and slick “no dieting needed” marketing, it’s really just another diet. The app is essentially a calorie tracker supplemented by lessons on behavior change and a personal coach who messages you. Many nutrition and mental health experts have warned that the way Noom presents itself is misleading.

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.

Interestingly, WW was one of the five providers in this national programme but was removed due to poor results.

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 digital basic price plans on each programme to show you how costs compare. All admin fees are included in these prices.

For basic monthly plans, Noom is the most expensive option. On the surface, Second Nature seems slightly more expensive than Weight Watchers.

However, you have the same coach throughout the Second Nature programme that you can build a relationship with rather than an ad-hoc response from a different coach each time.

Noom also provides this feature; however, on the Second Nature programme, your personal coach is a registered dietitian or nutritionist rather than a previous member (Weight Watchers) or an individual from any health-related background (Noom).

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 costly (£40-£100/hour). We have added a column representing this to compare costs (Weekly Nutritionist – WN).

Monthly digital subscriptions:

If you were to opt for the Weight Watchers face-to-face group meeting plan, it would be more expensive.

Example nutrition query response

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

Noom’s answer:

“No single food will stop or start weight loss. It’s all about balance! I suggest consulting with your doctor regarding specific needs (i.e. cholesterol).”

Weight Watchers’ answer:

“There is no need to avoid these, you can go to the gov website and get the correct information on this”

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 incredibly nutrient-dense, providing good quality protein and containing vitamins and minerals.”
