would like advice for weight loss -- heart trouble

I am trying to lose the final 10 lbs of my weight goal, but i dont want to continue pushing myself as far as I used to to lose weight. I have a heart condition (Super ventricular tachycardia) that makes it hard to exercise for any length of time, as well as a sinus arryhthmia that makes my heart beat too fast. I've been reducing my calorie intake, eat almost no fats, high fiber, moderate carbohydrate diet and trying to exercise as much as my heart will let me. I dont seem to be losing any weight, and i've been doing it this way for the last year. does anyone have a suggestion?

hi there i suffer with tachycardia docs are currentlyt doing tests on me but havnt found anything more yet, i find it so hard to exercise or keep myself active but what i have started doing is rather then going mad out exercising iv started walking i started a walking programme since then i have felt fitter and lost weight try that but be sure to start at the very minimum then work your way up hope i helped kim
