SlimFast is known worldwide as a weight loss brand. Founded in 1977, this Florida-based company helps people control their weight by substituting two meals a day with meal replacement shakes. Over the years, the company has added to its product lineup by creating meal bars, dietary supplements, snacks and packaged meals.

Most people remember the SlimFast motto used to be “two shakes a day and a sensible meal at night.” Currently, the company has replaced this idea with something simpler, called the “3-2-1.” “3” refers to the number of 100-calorie snacks a day that people following the plan should have. The “2” references the two different SlimFast meal replacement shakes or bars. Finally, “1” stands for the larger meal of the day, which should be about 500 calories.

Overall Rating of SlimFast

Many people have found success using this product to help reduce their weight. Consequently, this can be a good option for those who need a simple, calorie-specific weight loss product.

SlimFast Meal Replacement Shakes

4.5 out of 5 stars

It loses a half star due to the main ingredient, which is sugar. While the product currently contains much less sugar than prior versions of the meal replacement shake, it can still be a concern to those who have to watch their sugar intake or want to cut back.

How Do Meal Replacement Shakes Work?

Meal replacement shakes like SlimFast work by limiting the number of calories consumed during the day. When people stick to the plan, they consume about 1200 calories in the course of a day. A typical person burns 1800 calories a day just in normal daily activities, depending on the individual’s body. This means that on the SlimFast plan, you consume about 500 calories a day less than you potentially burn. To lose one pound, a person needs a 3500-calorie deficit. By dropping 500 calories a day, that means the loss of one pound a week.

The Benefits of the SlimFast Meal Plan

SlimFast meets the vitamin, mineral and calorie needs for two of three meals a day. The company also has a line of snacks for the required three 100-calorie snacks. All that needs to be added to the day is one 500-calorie meal. This could be breakfast, lunch or dinner, depending on the person’s needs for the day. For instance, meeting friends for Sunday brunch or mid-week lunch could be your big meal of the day. The plan is simple and flexible to allow it to easily fit into almost any routine.

Why Should Elderly People Take SlimFast?

One of the benefits of using the SlimFast plan is the ease of use. The shakes come in powder form or as premade drinks. This means less work for the elderly person, if he or she has to make the food alone, or for the caregiver. The only meal that needs to be prepared is the larger calorie meal. This can also be easy for any elderly individual who has someone to prepare meals. There are also many healthy frozen dinners available on the market.

Since many seniors have limited mobility, their caloric needs are generally less than an active adult. Maintaining a healthy weight or losing excess weight is important to lessen any age-related health problems brought on by being overweight. Another benefit of the system is that it’s easy to track calorie intake if the elderly person is using the meal replacements and line of snacks. Caregivers don’t have to guess what the person ate that day.

CONS

  • Higher sugar content
  • Artificial sweeteners (maltodextrin and aspartame)

The SlimFast meal replacement powder is mixed with eight ounces of milk to give the necessary vitamins, minerals and protein. In addition, the company makes ready-to-drink version of the shakes.

The shakes come in three basic flavors of chocolate, vanilla, and strawberry. The shakes boast 10 grams of protein per drink when made with eight ounces of milk. 

Other easy-to-use choices in the product line are snack bars, vitamin supplements, and 100-calorie snacks.

Sugar is the most dominant ingredient of the powder. To get the listed amount of protein, the shakes must be made with milk; any substitution alters the nutritional information provided on the packaging.

Ingredients of SlimFast Meal Replacement Shakes

  • Sugar is the first ingredient, which accounts for the high sugar content.
  • Maltodextrin is a type of artificial sweetener that can have side effects, such as causing upset stomach and loose bowel movements, in those that are sensitive to it.
  • Aspartame is another artificial sweetener with some controversy. Many health organizations, such as the U.S. Food and Drug Administration and the American Heart Association, have approved the use of this ingredient in food. Yet other researchers, such as from Harvard University, have found problems with the sweetener. It is also an allergen for people with phenylketonuria (PKU).
