A man lost over half a stone despite eating 10 slices of pizza every day for a month - and is now more ripped than when he started.<br /><br />Personal trainer Ryan Mercer, 34, ate pizza for breakfast, lunch and dinner and managed to lose a whopping three and a half kilograms during the 30-day challenge.<br /><br />He took on the challenge to show how calorie deficit diets allow people to lose weight without restricting their favourite foods.<br /><br />Ryan, from Bangor in Northern Ireland, carefully planned his diet and made all the pizzas himself, while maintaining his usual exercise regime.<br /><br />He said: "January is a tough month for people when it comes to fitness goals.<br /><br />"I aimed to highlight not only fat loss about calories in and calories out but that it's also not about restriction.<br /><br />"We don't have to restrict our favourite foods to get results and I also wanted to encourage more people to prepare their own food."<br /><br />Ryan's usual diet is a flexible approach to eating, with a healthy protein intake, and seven to 10 portions of fruit and vegetables each day.<br /><br />But for the challenge, Ryan ate nothing but pizza.<br /><br />He added: "I consumed pizza for breakfast, lunch and dinner every day.<br /><br />"I had two pitta pizzas and one larger dough-based pizza per day, this equated to roughly 10 slices per day.<br /><br />"Additionally, I left room for additional snacks."<br /><br />Pizza is one of Ryan's favourite foods, but due to his busy schedule, he found it difficult to make time to prepare the pizzas himself.<br /><br />"The hardest part of the entire diet was the preparation," Ryan said.<br /><br />"Pizza is one of my all-time favourite foods, so I enjoyed eating it all month, although I did ensure I had a large variety of different pizzas to give myself some variance."<br /><br />As he prepared everything himself, Ryan spent just under £10 per day on food.<br /><br />He added: "I home-cooked everything. The estimated daily cost was around £6-a--day for two pitta pizzas, and one dough-based pizza and three side salads.<br /><br />"Additionally, I spent around £2 or £3 per day on snacks."<br /><br />At the end of the month, Ryan became leaner, which surprised many of his followers online.<br /><br />He said: "This was a carefully planned dietary strategy. I designed a system, and this is what got me to my goal.<br /><br />"Daily calorie intake was set at 1800-2100 Monday to Friday, 2,700kcal Saturday and Sunday, daily protein target 140g per day, daily fruit and vegetable portion goal, seven portions minimum per day."<br /><br />Ryan only recommends the diet if it suits the person's lifestyle citing "everyone is different".<br /><br />His video reveal garnered over 2 million views online and has generated a huge response.<br /><br />He said: "I feel [that the video] has highlighted the confusion among the masses when it comes to fat loss and nutrition.<br /><br />"I've had some negative comments, some very funny ones and of course some positive feedback.<br /><br />"One thing we have in common is we all eat food so everyone has some sort of opinion when it comes to nutrition."
