DASH & WEIGHT LOSS

Archives of Internal Medicine

144 overweight or obese adults with high blood pressure were assigned to one of three approaches:

1. DASH

2. DASH plus exercise and classes on weight loss 3. Control

After four months, those in the DASH plus group lost on average 19 pounds—while the other groups either lost a little or gained weight.

DASH & WEIGHT LOSS

Annals of Internal Medicine

Randomly assigned 810 adults with borderline or mild high blood pressure to three groups:

1. General advice for controlling blood pressure

2. Goals: <2,300 mg. of sodium a day, lose weight, exercise, and limit alcohol

3. Same goal as #2, plus told to follow DASH’s dietary guidelines. After 18 months, the second group lost an average of about 8 pounds while the DASH group lost about 9½—both significantly more than the first group’s 3 pounds.

GLUTEN-FREE

Not just another fad diet – for some, a necessary lifestyle Celiac disease has increased dramatically in the U.S. since 1950 Now affects 1 percent of the population

Gluten – a protein found in wheat, barley, and rye, triggers an abnormal immune response that damages the lining of the small intestine Can cause diarrhea, cramps, pain, bloating, and vitamin deficiencies An estimated 6 percent (16 to 18 million people) are considered gluten

sensitive or gluten intolerant

Can cause many of the same symptoms without the intestinal damage

GLUTEN-FREE & WEIGHT LOSS

I M A G E : C N N . C O M 23

Any restriction typically leads to weight loss

Difficult to eat convenient, processed foods that are high in fat and sugar

INTERMITTENT FASTING

Eric Ravussin, director of the Nutrition Obesity Research Center in Baton Rouge, LA

1. 150 normal-weight or slightly over-weight men and women: consume 25% fewer calories at each meal

2. 75 similar people to eat their normal diet, for two years

Those who cut calories lost 10% of their body weight, despite only managing to eat 12% fewer calories

Lowered blood pressure

Improved insulin response

lowering risk for heart attack, stroke and diabetes.

But, why didn’t the calorie cutters cut more?

Cutting calories on some days may be easier

Eat “normally” 5 days a week Eat ¼ normal intake 2 days Fast days:

Women: 500 calories

Men: 600 calories

Choose lean protein & low-glycemic foods

INTERMITTENT FASTING & WEIGHT LOSS

International Journal of Obesity

166 overweight middle-aged women into two groups. Both groups were told to cut calories by 25%

1. Trim calories in each meal 2. Follow a 5:2 plan

Fast Days = 4 cups of low-fat milk, 4 servings of vegetables, 1 serving of fruit, low calorie drinks and a daily multivitamin.

So…what happened after 6 months?

INTERMITTENT FASTING & WEIGHT LOSS

calories daily

INTERMITTENT FASTING

& YOUR BRAIN

Journal of the American Aging Association

Deprived middle-aged rats of all food, every other day for three months Rats lost 23% of their body weight

Better motor coordination and cognitive skills than rats who could eat all they wanted.

Neurobiology of Disease

Bred mice to develop Alzheimer’s by middle age, but only had them eat every other day Mice delayed the onset of dementia by the human equivalent of 10 years Researchers believe intermittent fasting increases a protein that stimulates growth of new brain cells and the connections between them. But not yet able to say the same results happen in humans.

INTERMITTENT FASTING: THE BOTTOM LINE

For people who are overweight or obese, intermittent fasting is as effective

as a continuously restricting calories, and therefore can be an alternative approach to losing weight.

LOW FAT VS. LOW CARB

Christopher Gardner, an associate professor of medicine and the director of nutrition studies at the Stanford Prevention Research Center If you pool all the studies, there’s no difference in weight loss between

low-fat and low-carb. “Hugely disappointing”

LOW FAT VS. LOW CARB

Assigned participants to either Atkins low-carb diet, the Ornish low-fat diet or the Zone and LEARN diets that fell in the middle. After one year, the Atkins low-carb diet was slightly better on average But, weight loss varied greatly:

Some women lost 40-50 pounds

Others lost nothing or even gained weight

What could explain the difference?

LOW FAT VS. LOW CARB

Insulin resistant = lost more weight on the low-carb Atkins diet Not insulin resistant = no better on any one diet

Successes and failures might cancel each other out But when you tease them apart, there’s a bigger difference

NATIONAL WEIGHT CONTROL REGISTRY

Made up of more than 6000 people who have maintained a weight loss of at least 30 pounds, for more than a year.

1. Be active = 200 minutes per week of moderate-intensity exercise 2. Turn off the television = less than ten hours per week 3. Eat a low-calorie, low-fat diet = Average member consumes 1,380

calories per day

4. Keep your diet consistent = holidays or weekends 5. Eat breakfast = helps curb hunger and overeating later 6. Show some restraint = rarely overeat

7. Keep track of your progress = weighing and recording food intake

WHAT DIET IS RIGHT FOR YOU?

Ask yourself:

How long can I stay on this? How will you feel? Dietary preferences?

Think about what did and didn't work the last time you were on a diet?
