Christmas dinner is mostly greasy food, and holiday meat dishes are as few and refined as possible, with a combination of fat and thin, mainly thin. You can learn from the new concept of slimming put forward by Dr. Zhang Yushan specially invited by Beautiful University, and adopt the reasonable catering method of "three portions of alkali and one portion of acid", that is, as long as each meal contains three portions of alkaline food and one portion of acidic food, the simple difference is that each meal contains one portion of meat products or starch food, plus three portions of vegetarian dishes or bean products and fruits, I believe you will be as slim and healthy after Christmas.
