SAN FRANCISCO ( Reuters Health ) - Researchers at the Joslin Diabetes Center report that a 12 - week weight - loss program they devised for patients with type 2 diabetes continues to have a positive , long - lasting effect on weight loss 1 year later , long after patients are off on their own . The findings of a 1 - year follow - up of the 12 - week " Why WAIT " weight - loss program were presented here this week at the 68 th Annual Scientific Sessions of the American Diabetes Association by principal investigator Dr . Osama Hamdy . The study involved 85 patients with type 2 diabetes , average age 54 years and a disease duration of approximately 10 years . The average weight was 235 pounds , average body mass index ( BMI ) was 38 . 4 , average hemoglobin A 1 C was 7 . 5 percent , and average waist circumference was 46 . 7 inches . Patients completed the 12 - week diet and exercise program and were followed for another year without structured intervention . Twelve weeks of the intervention resulted in an average weight loss of 24 . 6 pounds -- more than a 10 percent reduction -- a waist circumference reduction of 3 . 6 inches , and an average drop of 0 . 9 percent in A 1 C to 6 . 6 percent , indicating good control of blood sugar . After 1 year of follow - up , weight remained lower than before the patients began the diet by more than 18 pounds -- a long - term loss of 7 . 6 percent . However , A 1 C levels increased to approximately 7 . 4 percent . Overall , 55 percent of participants continued to lose weight on their own , Hamdy said . The other 45 percent gained back approximately 5 pounds , but their final weight remained 2 . 0 percent lower than their pre - diet weight . Blood pressure , both top and bottom readings , were significantly lower at 12 weeks and 1 year compared with pre - diet readings , he added . Cholesterol levels improved significantly at 12 weeks , but had returned to pre - diet levels at 1 year , except for HDL , the " good " cholesterol , which remained significantly higher . Hamdy said there was evidence that kidney function improved as well , with a small decrease in protein in the urine . " The clinical implications are enormous , " Hamdy told Reuters Health . " We ' ve been glucose - focused for a long time . We need to be weight - focused . We need to focus on the cause of the problem and not the result of the problem . " The mainstays of the " Why WAIT ? " program are a low carb diet and tailored exercise . " We use significant calorie reduction and reduce carbohydrates to 40 percent of calories and increase protein to 30 to 40 percent of calories -- this is key for patients to maintain muscle , " Hamdy said . " In addition , we teach patients how to exercise , especially the type and the amount , and make sure it is age - appropriate . This is very important . " He added , " The main reason that patients regain weight is that they decrease their protein intake and don ' t exercise as much . The weight they gain is mostly fat , and visceral fat . " There is also an economic benefit . " Weight reduction leads to a reduction in need for medications . We saw a 65 percent - reduction in medical costs , or about $ 560 per year per patient -- and patients feel better , " Hamdy reported . 출처 : health . yahoo . com 체중 과 허리둘레 를 줄이 면 혈압 과 콜레스테롤 수치 가 낮 아 질 뿐 아니 라 , 당뇨 증세 를 크 게 완화 시킬 수 있 다 . 미국 조슬린 당뇨 센터 는 10 년 가까이 당뇨 를 앓 아 온 평균 연령 54 세 인 당뇨병 환자 85 명 을 대상 으로 12 주간 의 체중 감량 프로그램 을 실시 했 다 . 체중 조절 전 환자 들 의 평균 체중 은 약 105 kg , 허리둘레 는 46 . 7 인치 , 체지방 지수 ( BMI ) 는 38 . 4 였 다 . 저 탄수화물 식이 요법 과 운동 을 12 주간 실시 한 다음 , 이 들 은 평균 11 kg 정도 를 감량 했으며 허리 둘레 는 3 . 6 인치 나 줄였 다 . 이 덕분 에 환자 들 의 혈당 은 평균 0 . 9 % 가까이 떨어진 것 으로 나타났 다 . 또한 수축 기 와 확 장기 혈압 이 모두 확연히 낮 아 졌으며 콜레스테롤 수치 는 낮 아 지 는 반면 , 몸 에 좋 은 HDL 콜레스테롤 의 수치 는 높 아 졌 다 . 연구 팀 은 환자 들 의 소변 으로 단백질 성분 이 빠져 나오 는 양 도 줄 었 으며 , 신장 기능 도 향상 되 었 다고 밝혔 다 . 이 다이어트 프로그램 의 초점 은 지방 , 탄수화물 섭취 칼로리 를 40 % 정도 줄이 는 대신 , 단백질 섭취 가 하루 섭취 칼로리 의 30 ~ 40 % 가 되 도록 늘리 는 것 . 여기 에 운동 을 병행 해 근육 량 을 늘리 도록 했 다 . 이 같 은 체중 조절 프로그램 을 1 년 이상 지속 한 환자 들 은 당뇨 증세 가 완화 되 어 1 년 에 약 560 달러 씩 의 의약품 비용 을 절약 할 수 있 었 다고 한다 . 공유 하 기 글 요소 비 영리 동일 조건
