A healthy eating coach has issued a warning to Brits about unsustainable January diets, highlighting key red flags such as unrealistic promises and secret weight loss formulas. Vanessa Sturman, a behaviour expert with a decade of experience, says over 80 per cent of New Year's resolutions fail due to guilt, restriction, and unscientific claims.
Sturman, from Barnet, London, cautions against programmes that promise rapid weight loss, such as shedding 10kg in two weeks. She also warns of 'secret formulas' or miracle supplements that claim to eliminate belly fat overnight. 'Dramatic claims grab attention but rarely deliver lasting results,' she said.
Another red flag is fear-mongering, where influencers label normal foods as 'toxic'. Sturman cites seed oils as an example, noting that despite some claims, they are not inflammatory and can be heart-healthy. She advises that including treats in a balanced diet is acceptable.
Sturman also urges scepticism towards anyone who claims 'all the experts are wrong' about dieting, calling it 'classic clickbait'. She recommends questioning motives when individuals dismiss established research, such as claims that fibre is unnecessary.
To maintain resolutions, Sturman suggests gradual integration into daily routines rather than eliminating food groups. She emphasises that sustainable eating plans should be enjoyable and flexible, incorporating fruit, vegetables, lean protein, complex carbs, and healthy fats tailored to lifestyle.
