I usually jog continuously, and I usually start to burn fat after 30 to 40 minutes.
The longer the exercise time, the higher the proportion of fat in energy consumption.
Eating biscuit cereal doesn't mean you can lose weight, because biscuits are junk food, which contains a lot of sugar and is very high in calories. When you buy any food, you should first look at the calorie label on the back and make a rough estimate of the calories.
Generally, an adult does nothing and consumes about 2000 calories a day.
I suggest you add more protein. Eating only biscuits and cereal can only provide carbohydrates, which will lack a lot of vitamins and seriously affect your health. In addition, you can't eat too little, otherwise you will get thinner and thinner when you run, and most of the thin ones are muscles. Because the decomposition of fat requires the participation of carbohydrates, and you eat too little, the protein of your existing muscles will be decomposed into carbohydrates, leading to muscle loss!
Losing weight requires long-term persistence and short-term drastic diet reduction. Even if you lose weight, it is very unhealthy. Once it stops, it will rebound immediately. It is best to gradually reduce the daily calorie intake and exercise muscles at the same time, which can increase calorie consumption in the long run.
Also, running consumes little fat, and the main purpose of running is to speed up metabolism!
