Gwyneth Paltrow’s Goop has been heavily criticised for its bizarre and unfounded health and wellness advice.
Now the brand has come under fire for publishing a Q&A article with celebrity personal trainer Tracy Anderson, entitled ‘how to lose weight fast’, in which she shares her meal plan to lose 14lbs in four weeks.
A Harley Street nutritionist has branded the story ‘extremely damaging’ because she said it has the potential to harm the mental and physical health of readers.
Medical experts recommend a slow weight loss of around 1lb and 2lb a week – and say quick diet fads risk malnutrition, gallstones, exhaustion and can lead to eating disorders.
The exercise guru and pal of Gwyneth, who helped her lose her ‘baby weight’ after her second child, also recommends cutting out gluten and going ‘very low carb’.
But studies have suggested gluten-free products are laden with sugar and fat and have scant protein, while high-protein, low carb diets are feared to harm your heart.

Harley Street nutritionist Rhiannon Lambert says Tracy’s quick weight-loss advice is potentially harmful.
A host of other celebrities swear by the Tracy Anderson Method, including Jennifer Lopez, Madonna, Lena Dunham and Kim Kardashian.
But food expert Rhiannon Lambert has hit out at Tracy advocating quick weight loss results.
‘I am in complete shock that this article has been published as this has the potential to harm a lot of relationships with food,’ she told The Independent.
‘Firstly it is important to note that fast “weight loss” is often not body fat but the number on the scales shifting, often from water weight, which is why I always advocate a healthy balanced approach over time to losing actually body fat as weight.’
NHS Choices recommend the safe weekly rate of weight loss is between 0.5kg and 1kg (between around 1lb and 2lb a week).
It states: ‘Lose weight faster than this and you’re at risk of health problems that include malnutrition and gallstones, as well as feeling tired and unwell.
‘Fad diets associated with very rapid weight loss, which involve simply changing your diet for a few weeks, are also unlikely to lead you to a healthy weight in the long term.’
The controversial diet plan
In the Goop article, Tracy said: ‘If you have weight to lose, you can effectively do a fourteen-pound weight loss in four weeks.
‘This requires focus and physical, mental, and emotional willpower. You will experience short-term stress (particularly during your cycle if you’re a woman) – but this can end up being less stressful than living with the stress of excess weight.
But Rhiannon stresses that ‘quick fixes never last’.
She said: ‘They are just that: quick and not sustainable. In fact, they may end up affecting how you manage your weight long term.’
Experts say the most effective way to lose weight and keep it off is to lose it gradually.
Rhiannon also said one of Tracy’s recommended breakfast options contained ‘detox tea’ and her own protein powder which she says contains cane sugar and sunflower oil when ‘there are much better options out there’.

Concerns over gluten free and low carb advice
Tracy also recommends cutting out gluten from your diet and going ‘very low carb.’
But according to Rhiannon, the claim that doing these two things will lead to weight loss is ‘utterly scientifically incorrect’.
The demand for gluten-free has exploded in recent years, but experts have warned about the dangers of excluding nutrients and argued such products often contain more fat and sugar to help create the texture that is lost when gluten is excluded.
Low carb diets have raised alarm among experts because they tend to be high in saturated fat, potentially raising cholesterol and your chance of heart disease.
Rhiannon points out that many studies have shown that people tend to lose weight on any diet that restricts a whole food group because overall calories are lower – but it’s not healthy.
She says that it is not sensible to eliminate whole food groups because you may end up deficient in micronutrients as well as risking messing up your guy bacteria.
Tracy also claims in the piece that you can ‘jump-start’ weight loss by working out every single day.
But Rhiannon, whose book Re-Nourish is published on 28 December, argues that working out every day can actually hinder your results as you don’t give your muscles time to recover.
‘In some cases the stress on the body alone may delay and hinder any desired weight loss,’ she said.
Since its launch in 2008, Goop has urged we try sex dust, vaginal steaming, vaginal jade eggs, cupping, earthing (walking barefoot) and consulting shamans.
The site’s controversial claims have now earned the company the first ever ‘Rusty Razor’ award as the ‘best’ promoter of the ‘worst pseudoscience of the year’.
The accolade was issued by The Skeptic, which describes itself as the UK’s only magazine taking a scientific look at pseudoscience and the paranormal.
