Slice the carbs off, if you really cut the cereals and potatoes starch off and watch the sugars like a hawk you will lose weight, due to allergies I watch my sugars and even a natural yoghurt has around 5 gr in it… there are protein bars with stevia and poliols as sweetners those might help since most others are loaded with sugar... you will get craves after a month so eat something like bread once a month it's ok, just not everyday as you try to lose some weight... also your taste will change, bitter things will turn way more rounded in flavour and two months on this and after you try something with "average" sugar content will make you nausiated and wanting to puke. That is how much extrasugar people are used to eat without actual need.
