Hi all,
I've lost some weight lately by following a somewhat low-carb program (no sweets, sugar, etc.), in combination with physical exercise. I've been reading a lot about the optimal amounts of carbs and fat one should consume in order to be losing weight. However, I am confused about these points:
1. How does physical exercise burn the calories that one consumes with meals? Let's say I ate a dinner containing 40g carbs, 20g fat. Then I immediately went for a one-mile walk. That means the loss of about 100 calories, according to calorie calculators, equivalent to 100/4 = 25g carbs. Does it mean my "net" carb intake from the meal was only 15g? Or is this reasoning too simplistic? Would I also be burning fats at the same time?
2. Let's say I didn't eat before talking a walk. The 25g of carbs (or its equivalent in fat) must have come from somewhere. From my reading, it seems they must come from the glycogen stores in the muscle and liver. What happens next? Do I just walk around with half-empty glycogen stores until the next meal, or does my body immediately start converting fat stores into glycogen?
Just curious.
