A leading doctor has revealed the top breakfast foods, including some very common ones, that could be causing you to not actually lose weight.
Professor Tim Spector, a doctor and epidemiologist, chatted to diet guru Michael Mosely on a recent episode of his BBC podcast Just One Thing, opening up about the breakfast he had for 10 years which unbeknownst to him, resulted in an additional 10 kilograms being added on to his weight.
The nutrition expert, who cofounded the ZOE study, ultimately switched up his morning meal after he spotted his blood sugar levels spiked around that time straight after he ate what he thought was a "healthy diet".

In the episode, he explained that foods like toast and marmalade, a cup of tea and a glass of orange juice made him rack up weight and urged people to experiment with their breakfast to find what works best for them.
He said: "When I was a healthy doctor epidemiologist, it [breakfast] would be mostly a cup of tea with low-fat milk in it. And a nice glass of orange juice, toast and marmalade. It would be brown toast - I didn't know at that time that they're often dyed brown.
"I was eating towards what I was told at the time as a doctor was a healthy diet. And it turns out that that diet had led to me gaining about a kilo in weight over the previous 10 years so that I'd gained about 10 kilos over that time. And it was only when I stuck a glucose monitor on me as I was eating my breakfast that it shot up into the normal diabetic range.
"There was a worrying sign that really these carbs and sugars weren't right for me."
Professor Spector continued explaining that his wife's blood sugar levels reacted differently to the same breakfast, urging people to try out different foods. He added that he now has a breakfast of full-fat yoghurt with nuts, seeds and berries and switched tea to coffee which helps him stay full until lunch.
He explained: "This is why I say experiment with your breakfast because, for me, it was good to change to a high-fat breakfast.
“So, I have full-fat yoghurt with some nuts and seeds sprinkled on there and whichever berries I happen to have - either frozen or fresh depending on the season. I switched my tea to coffee because we now know coffee is really good for your gut microbes."
"It was a radical difference. And I instantly saw that changing brought down my sugar. I wasn't getting sugar spikes. I also didn't feel nearly as hungry at 11 O'clock at work. I didn't feel I needed a mid-morning biccy as I used to and I was just feeling generally better."
