You've just started exercising, so it's estimated that your body fat will not be very low. Besides, you like to eat cakes, because most of them lose fat first and then gain muscle. I also lost fat first. Although I am not very fat, I still want to lose weight, because the fat is under the skin and the muscles are under it, just like the snow covers the earth. It is difficult to grow muscles under fat. As for eating cakes, although there are eggs, they are different in nature. Steamed at high temperature with a lot of oil. My house is next to a cake shop. Don't you think you have a lot of oil in your hand? I suggest you do a personal fat test first and try to eat less greasy food.
Finally, I wish you success in fitness!
