1. Personal physique is different: everyone's physical condition and metabolic rate are different, so you need to make a diet plan that suits you according to your physical condition.
2. Different nutritional needs: Different age groups, genders, occupations and other people have different nutritional needs, and Andrew's diet may not meet everyone's nutritional needs.
3. Different eating habits: Some people may find it difficult to change their eating habits. Even if Andrew's diet is used, the expected effect may not be achieved.
4. Health problems: Some people may have special health problems, such as diabetes and hypertension, and need to follow the advice of doctors or professionals to make a diet plan.
So, although Andrew's diet may be helpful to some people, it is not a universal diet plan for everyone. It is suggested that you can consult a professional dietitian or doctor when making your own diet plan.
