Low-Carb Diets and Your Blood Sugar
Do low-carb diets help reduce your risk of diabetes?
Not if the carbs are upstaged by meat, cheese, and other unhealthful sources of fat. A better way: Get your protein and fat from vegetable sources. It could whittle your risk of diabetes along with your waist.
Low-Carb Lingo
When women in a study took a smart approach to low-carb eating — sticking to plant sources of fat and protein instead of loading up on cheese, bacon, and the like — their risk of diabetes actually dipped a bit on the low-carb plan. More studies are needed to determine what impact low-carb eating has on other health factors, like heart health, cancer risk, and long-term weight management.
Carb Conundrum
The other caveat with a low-carb diet is that some of them seriously restrict whole grains and veggies. Not exactly a recipe for good health!
Carbohydrates have gotten a bad rap, and that’s a shame. Eat the right kind of carbs — the low-glycemic index (GI) kind — and you’ll lose weight and lower both LDL and total cholesterol. Eat the wrong kind and . . . well, your heart suffers the consequences. GI index refers to how quickly starches break down and affect your blood sugar. Opt for low-GI lentils, beans, bran cereal, and high-fiber fruits and veggies to reach your lighter, heart-healthier goals.
Don’t be swayed by low-carb diets. You need carbs to supply your body with energy, fiber, B-vitamins, magnesium, and other important nutrients. Completely eliminating carbs from your diet isn’t healthy. Instead, go for low-GI carbs, the kind your body digests slowly, to help keep your blood sugar steady. You’ll stay full longer, have more consistent energy, and feel better overall.
Researchers recently tested this out with four groups of obese men and women. Each group followed a different diet, but calorie intake was the same (women 1,400 calories a day, men 1,900). The diets varied in their percentage of protein, high-GI carbs, and low-GI carbs. After 12 weeks, all groups lost weight, but the people who got the most calories from low-GI carbs also lowered their LDL and total cholesterol levels. The people in the high protein/fewer carbs (mostly high-GI carbs) group experienced an increase in LDL and total cholesterol levels. Ouch!
