What to eat
According to Holland and Barrett, you should stay clear of processed sugars and complex carbohydrates.
“Instead, try and include plenty of soluble fibre foods such as flax seeds, avocados, blackberries, and Brussels sprouts,” advises the health body.
Why? “This is because soluble fibre absorbs water and forms a gel that helps slow down food as it passes through your digestive system.”
As it explains, it helps you feel fuller for longer, so you end up eating less and not snacking excessively.
