To create energy, your body burns fat or it burns blood sugar (glucose), but it can''t burn them both at the same time. When you''re not doing anything strenuous your body burns fat. When you exercise into the aerobic zone (70% or more of your max. heart rate) your body will stop burning fat and instantly begin to burn blood sugar – because blood sugar can be converted to energy much faster than fat.
Aerobic exercise will burn fat – but only after you''ve depleted your available blood sugar – which, for most people takes at least 20 to 30 minutes of being in the aerobic zone. Countless overweight individuals are on the exercise bikes and tread mills, pedaling and running, until their heart almost pounds out of their chest but they are not burning fat. The first 30 minutes only burns off blood sugar – after that you''d need another 30 minutes to burn any fat. Exercise equipment sales are on the rise and so is obesity – does that make sense to you?
The truth? Walking is the best type of exercise for healthy weight loss. Walking burns fat. Walking also builds lean muscle which "feeds" on the body''s excess fat. Walk daily, eat whole foods, drink plenty of water, and turn your body into a healthy, energetic, fat burning machine that incinerates fat 24 hours a day! Once you move closer to your ideal weight, then adding some aeorbic exercise is a great way to maintain your weight and support your heart, lungs, muscles, and circulatory system.
Now that you understand the real problem and know how to avoid the big mistakes - let''s learn how your body reacts to fad diets like the low-fat, and low-carb plans.
