How to Make a “Sensible” Meal

SlimFast has you covered for two meals and three snacks per day, but you’ll be on your own to make your own healthy meal, or to make smart decisions when going out to eat.

If you don’t know how to make healthy meals, then this part may be scary for you.

They have a large database of healthy recipes that you can use for your one sensible meal of the day. So, if you’re wondering what one of these meals looks like, checkout their website for some great ideas.

Is Slimfast Keto?

Good news keto fans! Slimfast does, in fact, work with the keto diet. While you can use their regular shakes, and still be keto compliant, they recently launched a new line of shakes and snacks that are designed specifically for a keto diet plan.

If you’re new to keto, SlimFast has out together a guide that shows you exactly how to use their products, as well as what kind of meals to eat, and tips for exercise as well.

How the Slimfast Keto Plan Works

  • Eat One Low Carb, High Fat Meal (500 Calories)
  • 2 SlimFast Keto Meal Replacements (Shakes, Bars, Etc.)
  • 3 Low-Carb Snacks (100 Calories Each)
  • Drink at Least 64 Ounces of Water per Day
  • 30 Minutes of Light to Moderate Exercise per Day
  • Men Can Add a Low-Carb, High Fat “Mini Meal” to Their SlimFast Meal Replacments

Real Before & After Pictures and Testimonials

Amy's before and after pictures

SlimFast has been helping people reach their weight loss goals since the 1960s, so it’s a pretty safe bet that there are literally thousands of testimonials out there!

They have some super inspiring stories posted on their website, so be sure to check those out, but there are just a couple that we thought were worth sharing here.

I have had several people at LA Fitness ask me what I was doing because I look better each week! I said SlimFast! Even an attorney friend of mine saw me at the gym and said “every eye in this gym is on you”. I laughed! It feels great, I have more confidence, and I feel that I will now have more success in my career! Thank you SLIMFAST.

I began The SlimFast Plan and right away I knew it was the plan for me. I have tried several weight loss plans and fad diets through the years. This plan fit my crazy, busy lifestyle perfectly. It was so easy to follow and everything I tried, I loved the taste of. I loved that I could have all my meals and snacks right on hand.

I enjoy the SlimFast Plan because it doesn’t feel like a diet to me. The SlimFast Plan is tasty and there are so many ways that you can blend, combine, and create new ways to enjoy the smoothies, shakes, and powders. Though I can’t get back the past 20 years before starting the SlimFast Plan, I know I’ll be in shape for the next 20 years ahead…and now my girls will have a tough time keeping up with me! Thank you SlimFast.

How Much Weight Can You Lose?

Results are going to vary for everyone, but most folks can expect to lose 1 to 2 pounds per week when they follow the SlimFast Diet Plan.

Those with the most weight to lose, may see a lot more weight loss, especially during their first few weeks on the diet.

How Much Does SlimFast Cost?

SlimFast products range in price from about $5.00 for their snacks, to about $8.00 for a four-pack of their meal replacement shakes.

You can also buy their shakes and snacks in bulk, which can bring the cost per bar or shake down, so that’s an option to consider if you plan to use their weight loss products for a while.

Where Can You Buy it?

The nice thing about SlimFast is that you can find it in most major grocery stores. If you don’t have access to SlimFast where you live, it can also be bought online – Amazon is my favorite place to buy.

Review Summary

SlimFast has been proven to be a powerful and effective weight loss program. It’s super easy to follow, the shakes and snacks taste great, and they have a variety of plans to choose from.

If you’re looking for a diet plan that isn’t overly complicated, can be bought at most grocery stores, and is super affordable, then the SlimFast Diet Plan is definitely worth considering!
