A drug-free fat pill could assist weight loss by stopping over-eating.
Scientists are conducting trials on a capsule that tricks the body into thinking it is full, with early investigations showing promising results.
The pill works in a similar way to jabs such as Ozempic but is completely natural and contains fruit and vegetable ingredients - making it cheaper and possibly without side effects.
Early trials conducted on 60 people found that eight in ten ate less food after taking the pills on a twice-daily basis.
The pill's chief inventor Dr. Madusha Peiris, a neuroscientist at Queen Mary University in London, said: "We have developed a way of hijacking the system that all humans have to sense nutrients and make us feel full.
"So far nobody has had any side effects and we suspect that is because these are nutrients that are in your diet anyway, which is very different to a drug.
"No other company is taking this nutrient-based approach."
