Why are there no official syn calculators?

Mainstream weight loss plans rely on principles and ratios to assign “syn” values to foods, indicating their calorie content. While these plans provide syn allowances, they avoid emphasizing syns to prevent overindulgence in treats. Official syn calculators are unlikely due to the complexity of food variations and the risk of promoting high-calorie consumption. By not providing a calculator, plans encourage members to use their resources, fostering better program understanding and adherence. Additionally, official materials may serve commercial purposes for these programs.
