The 3 Day Diet is low calorie, but it certainly is not low-fat, low-salt, or low cholesterol, so it is not a healthy option for most people with certain medical conditions such as diabetes, hypertension, heart disease, and high cholesterol. If you are overweight, weight loss is key to managing these conditions. But it should be a healthy and sustainable weight loss that includes healthy nutrition and exercise.
Real talk: It could take weeks or months to see the metabolic effects of exercise on the scale, and even then, building muscle, which is denser than body fat, could lead to weight gain. "Do what you like because it’s good for you," Dr. Seltzer says, noting the way exercise is awesome for your heart, mental health, and more—and that not all measure of progress can be seen on the scale.
During the 3 days of the diet, balanced nutrition is lacking. Some of the foods that are recommended are high in salt and fat and would not be appropriate for people with certain medical problems like heart disease, high blood pressure, diabetes, or high cholesterol. You may not be getting enough vitamins, minerals, and fiber while you are on the diet. If you are taking medicine for your diabetes and want to try the 3-day diet, it's important to talk with your doctor first about how to adjust your medicine.

Other diabetes medications. Insulin-releasing tablets (e.g. sulphonylureas) often lead to weight gain. These include: Minodiab, Euglucon, Daonil, and Glibenclamide.

High blood sugar levels coupled with high blood ketones, on the other hand, will mean that you have a pathologically low level of insulin – something non-diabetics do not suffer from. This can lead to ketoacidosis – a potentially life-threatening condition. If this happens, you’ll need to inject more insulin; if you’re at all unsure of what to do, contact a medical professional. Coveting really high blood ketones for weight control is not worth the risk for type 1 diabetics.

After his 14 years in bodybuilding, Juge testifies that he's found many restaurants are accommodating, so there's no reason to avoid them as long as they'll cook to your preferences.
