Without dieting, some people worry that running can't reduce fat, just because running can promote appetite growth. Especially for some novices who never exercise, when they start running training, they will feel hungry after exercise, so it is natural to increase their food intake. If you don't control the food you eat, it may indeed lead to the effect of reducing fat is not obvious and it will be lost in vain. Others will lose their appetite because of exercise, especially high-intensity exercise. In a longer exercise cycle, it is a general trend that food intake increases due to regular exercise.
Without dieting, athletes' appetite increases, which can offset the negative impact of increased food intake caused by exercise on fat loss. For beginners who have just started running to lose weight, have high body fat rate, are overweight or obese, the effect of running without dieting will be more obvious. This is why obese people can still achieve significant weight loss even if they don't control their diet at the beginning of exercise.
Not only running, but also other aerobic exercises and strength training. As long as you want to enjoy delicious food and keep slim, high-intensity exercise is the price you must pay. High-intensity exercise consumes body fat in a shorter time, and the effect of consuming excess fat under the skin is better. Studies have shown that high-intensity exercise at least three or four times a week can achieve obvious and satisfactory fat-reducing effect without dieting.
If dieters want to achieve the goal of sustained fat loss through running or other exercises, they must constantly improve and promote the difficulty of exercise, that is, the intensity and duration of exercise always increase slightly. That is to say, even if you are an exerciser who runs regularly for a long time, if the running plan has changed for thousands of years, such as always running at a uniform speed of 5 kilometers, the fat-reducing effect of running will slow down or disappear.
