Optifast is an effective medical weight loss and weight management system. It employs a meal replacement diet program that potentially results in fat loss and an overall reduction in body mass. It also helps users to modify behaviors and make more enlightened food choices for lasting health and weight loss.

How long do you stay on Optifast?

You can keep drinking and eating shakes, bars, and other nutritional products indefinitely. The patient journey has three phases. The first phase last 12 weeks. During this phase, you follow a full meal replacement diet. During the second phase, which lasts six weeks, you consume a mixture of meal replacement shakes, bars, other Optifast products like vegetable soup and chicken soup, and whole food. The final phase entails long-term management in which you continue consuming meal replacements and whole food.

Can you have alcohol while on the program?

Yes and no. In general, Optifast does not prohibit your alcohol intake but advises against it, especially if you're on the very low calorie diet weight-loss regimen, and particularly during the intensive phase. However, you're not expected to abstain from social situations. The company merely suggests you consume alcohol mindfully, keep yourself sufficiently hydrated with water, and bear in mind that alcohol contains carbs and calories that may slow down or inhibit fat loss.

Can you drink coffee on Optifast?

You can drink coffee on Optifast. It is recommended that you consume your coffee black or at most with 1 ounce of skim milk and sweetened with a sugar-free alternative, such as Splenda or Equal. For convenience and added nutrition, there is the very low carb diet coffee-flavored shake. It supplies clean proteins, vitamins, minerals, prebiotics, omega-3 fatty acids, and coffee extract that supplies a much needed caffeine boost in the morning or afternoon.

What kinds of proteins are in these products?

There are several different types in the ready-to-drink shakes and shake mixes and meal powders. They are the following:

  • Calcium caseinate: Derived from skim milk casein, calcium caseinate is the main component of cheese and is a slow-digest product.
  • Soy isolate: This comes from soy flour and is naturally low in fat and carbs.
  • Milk isolate: A low-fat, filtered combination of casein and whey.
  • Whey isolate: A byproduct of cheesemaking, whey is a fast-digest product.
