My aunt is a weight loss instructor, and here is some VERY key information in how you can lose weight. Aerobic training is the only form of exercise where you use two sources of energy: carbs (blood glucose) and fat.
The Surgeon General advises us that, to be healthy, we need to exercise at least three to four times a week, in an aerobic zone, for 20-30 minutes. That is a standard to keep your heart healthy, not to lose body fat by burning calories.Here's what you need to understand. For the first 20 minutes you are exercising in your aerobic zone, you are burning about 80% carbohydrates and 20% fat.
For the next 20 minutes, you are burning about 50% carbs and 50% fat. You're getting better. Now you're gonna start to lose some of that weight as the fat is being burned! So what happens if you start getting into the above 40 minute range? A reversal. You are now burning about 20% carbs and about 80% fat. So, here goes. You burn more calories per-second while training aerobically than during any other form of exercise. If you want some more tips then ask for some, I have tons. Also remember, if you want to lose weight relatively fast, then your just gunna have to work longer!
