Macronutrients for CR

[Guest guest]

Hi All,

A not pdf-available below paper reviews the evidence for diets using different

macronutrient ratios and seems to conclude that a diet of reduced simple sugars

and

inclusion of essential fatty acids works well to achieve consistent CR.

Persistence

in the diet selected matters.

The Effects of Low-fat, High-carbohydrate Diets on Plasma Lipoproteins, Weight

Loss,

Although there is consensus about restriction of dietary saturated and trans

fatty

acids, cholesterol, and sugars, there is debate about what the optimal total fat

and

carbohydrate content of the diet should be for weight loss and coronary heart

disease (CHD) risk reduction. The overall evidence that dietary composition

plays an

important role in determining caloric intake is limited. Three recent randomized

trials have indicated that low-carbohydrate diets are more effective in

promoting

weight loss in overweight and obese subjects over 4 to 6 months, but not over 1

year. In our own randomized trial no such differences were noted, and compliance

with extreme diets was limited. Moreover little attempt has been made to control

for

the type of carbohydrate used in the low-fat, high-carbohydrate arms of these

trials. Available evidence suggests that restriction of sugars and carbohydrates

having a high glycemic index would be preferable to total carbohydrate

restriction,

and that an increased intake of fiber and essential fats (especially omega-3

fatty

acids) is also important for overall heart disease risk reduction.
