I need to lose weight about 25/30 kilos. I'm basically eat vegetarian food but on very rare occasions will eat a small amount of fish ie fish and chips. My problem is I'm still gaining weight, I had major heart surgery last year and have ongoing mobility issues, I'm also on a variety of drugs including one for epilepsy although have only had the one major seizure. Currently I'm unable to swim but I'm hoping this will change shortly. I eat lots of vegetables and fruit (mostly berries) but I love grapefruit, melon and apples too. I eat a few nuts and cheeses, I will eat free range eggs but again very rarely. I do eat pasta, jacket potatoes and rice but in moderation and have been known to have the occasional sweets although chocolate I guess is my choice is eaten once or twice a fortnight and the equivalent of 1 or 2 squares each time. How can I improve my weight I'm also suffering breathlessness due to carrying the excess weight?
