Struggling with Weight Loss

Hi Fellow Pursures of health, I am 40lbs over weigth and classified as Obese by my doctor. I have been trying to lose the weight many years now but to no avail. I lose 5-10lbs here and there but it ALWAYS comes right back with a friend or two. I recently changed to a Semi Vegan life and it has been six months and I still have not lost poundage. I have lost inches but no real significant weight loss. I exercise at least 4 days per week; both weights and cardio. I eat only organic fruits and veggies. No breads or Pastas. My sugar intake is reduced to agave nectar to sweeten my tea (not daily) and the natural sugars consumed from the fruits I juice. I AM THROUGHLY FRUSTRATED and do not know what else to do... Should I detox my organs to boost my metabolism? should I fast NO food only water to jump start my metabolism? Is there anyone out there that has been where I am and found a success resolution that resulted in significant weight loss? I am desparately seeking wisdom and insight..... Tweet
