While this thread is getting long, I'm new to this area so here's my .02 worth:
Now 40 years old, 160 pounds for the last 4 years, blood pressure and cholesterol normal and feel great.
About 5 years ago, weight near 190, normal pressure and cholesterol and suddenly saw blood pressure shoot up 20 points. Tried every diet, low salt, high grain, pyramid, etc diet and saw weight go up, as well as blood pressure and cholesterol. Throughout and before all diets, have been on my mountain bike for around 50-75 miles per week, riding hard. Not a couch potato at all, but definitely carrying too much weigh despite the exercise and "pyramid diet". Heart ultrasounds ekg's, ecg's, etc all showed everything perfectly normal.
So as a last ditch effort before taking pressure med's, my doctor suggested Atkins. He had seen rare cases of carb reactions/allergies and figured it was worth a shot. We were monitoring everything very closely, so why not.
Within a week, blood pressure down to normal, cholesterol down below 200, weight dropping so fast my kidneys hurt. Within a month, had lost over 20 pounds while eating like a pig. To deal with the kidneys, I started eating way more veggies, and all was fine. After losing 30 pounds, I started looking like I was from a warcamp, so introduced more carbs, but only natural (more veggies, fruits, potatoes, etc) and found that I could stay at 160 without any effort, and felt great. So I'm not really on Atkins hardcore at this point, but all processed sugar is out, as are most grains. Grains, especially whole wheat, give me such bad stomach aches, that I believe they were the culprit of my problems. Even when I sneak a slab of birthday cake I feel fine, but a slice of wheat bread and I want to get sick.
So, due to regular check ups and some effort, I've found what makes my body happy. I've fought weight gain all my life, ranging from 150-190. Not anymore. Had I not gone for my regular checkup and had a willing open minded doctor, I'd probably still have high blood pressure, cholesterol, weight and feel like crap. People are constantly telling me that Atkins will kill me, but as soon as I switch off it, pressure, cholesterol and weight go back up within a week. Everyone is different here, but if something doesn't seem to be working, chances are it just isn't right for your body type.
Typical meals now..breakfast: 2 eggwhite omelette, bacon, lunch: big spinach salad, tuna, chicken, roast beef, whatever meat I'm in the mood for. Dinner: more salad, veggies, some meat and cheese 'til I can eat no more.
