How Did Slimfast Advanced Energy Start?

Slimfast products have been on the market for more than four decades. The company was first produced by the Thompson Medical Company which was established in the 1940s. According to Wikipedia, the Thompson Medical Company was also responsible for Dexatrim, a controversial diet product that resulted in side effects and drug interactions.

In 2000, Unilever purchased Thompson Medical and sold the Slimfast brand to Kainos Capital in 2014. Since taking over, Kainos Capital has re-branded the product, made several changed to the original Slimfast formula and unveiled a new line of Slimfast diet products.

Slimfast Advanced Energy shakes are part of the “3-2-1 Diet Plan.” This plan calls for three 100-calorie snacks, two meal replacement shakes and one meal a day.

Slimfast Advanced Energy Claims

Slimfast makes the following claims about their Advanced Energy shake mixes:

  • Curbs hunger
  • Reduces cravings
  • Tastes great
  • Supports your digestive system
  • Packed with vitamins, minerals and protein

Did we find any truth to the claims made by Slimfast? Our research team had to take a long look at the Slimfast Advanced Energy ingredients and nutrition facts before we concluded.

Nutrition Facts

Slimfast Advanced Energy Nutrition Facts

Slimfast Advanced Energy nutrition facts are fairly straightforward.

Every Slimfast Advanced Energy shake mix contains:

  • 20 grams of protein
  • 5 grams of fiber
  • 24 minerals and vitamins
  • 1 gram of sugar
  • Caffeine

The nutrition facts aren’t surprising, but they offer no evidence that Slimfast Advanced Energy is any more effective than other meal replacement shakes.

Slimfast Advanced Energy nutrition provides everything you would need if you’re planning to drink shakes as a meal replacement. Are liquid meals a safe and effective way to lose weight? Keep reading to see what our research team uncovered.

Does it Work?

Do Slimfast Advanced Energy Shakes Work?

There is some evidence that supports Slimfast Advanced Energy shakes effectiveness. One of the most promising aspects of the nutrition is the protein content. Several studies, including this one from the American Journal of Clinical Nutrition, show that a high-protein diet can reduce hunger, calorie consumption, and body weight.

Livestrong researchers found that the shake diet plan calorie restrictions problematic. Replacing two meals a day with Slimfast shakes results in a reduced-calorie diet. Low-calorie diets are difficult to follow for periods longer than three to five days. One study reviewed by the International Journal of Obesity concluded that low-calorie diets can reduce your metabolism. Even more concerning is the fact that your metabolism will remain low for extended periods following a low-calorie diet. This Obesity Journal(Silver Spring) study suggests metabolic adaption for periods of six years or longer.

The American Journal of Clinical Nutrition concluded that low-calorie diets can increase your chances of developing osteoporosis. Another Clinical Journal of Sports Medicine study found that low-calorie diets can severely affect your immune system.

So, to answer the original question shakes to lose weight fast can work, but there are long-term effects that should be considered.

Slimfast Advanced Energy Benefits and Results

There are pros and cons to the Slimfast Advanced Energy shakes. We love the fact that the makers of Slimfast provide specific scientific studies to support their claims. Slimfast is simple to use, rarely results in side effects and does help dieters lose weight in the short term.

What we’re not crazy about is the fact that Slimfast Advanced Energy shakes contain no proven metabolism boosters or fat burners. Obesity is at epidemic levels in American for a reason. Losing weight is difficult. Adding an effective diet supplement can drastically increase your chances of losing weight and keeping it off. One randomized, double-blind, placebo-controlled trial published by the Journal of Medicinal Food found that adding Meratrim to your diet may double the amount of weight you lose.

Another reason we’re not entirely sold on Slimfast is this product doesn’t retain its effectiveness over long periods of time. High protein meal replacement shakes are a great way to shed a few pounds, but severely limiting calories is not sustainable for long periods of time.

Details on Slimfast Advanced Energy and Weight Loss

Our research team always considers reviews from verified users whenever we investigate a diet product. The majority of dieters were happy with this shake diet plan. The shakes weren’t as chalky as other Slimfast formulas, they liked the taste of the ready to drink formula, and most verified users agreed that they did receive a boost of energy from this product.

Did these verified users lose any weight on the Slimfast shake diet plan? Many said they did. The average amount of weight loss was one to two pounds a week. But, the real test is whether or not the dieter can keep off the weight when they stop using Slimfast Advanced Energy shakes.

How to Use Slimfast Advanced Energy Shakes

Drink a Slimfast shake twice a day in place of two meals. The Slimfast Advanced Energy diet program is available in Slimfast Advanced Energy powder and ready to drink shakes. One scoop of Slimfast Advanced Energy powder can be blended with water, skim milk or almond milk. Slimfast recommends that you drink their products chilled, although several verified users enjoy drinking their shakes hot, like coffee or tea.

Potential Slimfast Advanced Energy Side Effects

Commonly shared side effects associated with Slimfast Advanced Energy may be related to this product’s caffeine content. The product contains the same amount of caffeine as a large cup of coffee.

If you’re not accustomed to extra caffeine in your diet, you may experience:

  • Rapid heart rate
  • Insomnia
  • Nervousness
  • Nausea
  • Stomach irritation

What Users Are Saying

I love regular Slimfast and have used it for many years but this tastes so strong of artificial sweeteners. I can’t use this:[“

I mix this with collagen, instant coffee & cinnamon in a big jar, then use a big scoop in HOT water to make the drink I use to take supplements with.”

“Next to no results within 2 weeks even coupled with proper diet.”
