Yes, the HCG diet has been known to cause clotting issues. In fact, it is mentioned as one of the most frequently reported side effect. Please do not use this diet but rather choose a 1200 calorie balanced diet with 3 main meals and 2 snacks per day with an exercise program for 150 minutes per week at 70% of your Target Heart Rate. Weight loss will not come off to stay off unless lifestyle changes are committed to. Are you ready to do that? Start measuring and weighing your foods until you can accurately visualize common portion sizes. People often eat more than they think. Here is a general template for your diet.
