First of all, how was your long weekend? I feel like the long weekend went by far too quickly! On Friday I had a whole lot of nothing planned so I was looking forward to a nice relaxing weekend, now the weekend is over and I’m looking forward to next weekend already. This weekend I took my dog Mocha to the vet for her annual check-up, made two different kinds of cookies, baked with my mom, cleaned the house, watched the Remembrance Day ceremony, made Jambalaya, went for a run and went to Costco. If you’re looking for a good time to go to Costco, I found Friday at about 5:30pm not too busy! I picked up a ton of new food items to review when I was at Costco.

I feel like I’m a protein shake expert because I drink one pretty much every day at work and so does Sean. Protein shakes can be either pretty good, okay, or really bad. For a lot of people protein shakes make an easy, convenient meal or snack. They also are great for individuals who struggle to get an adequate amount of protein into their diet. I like them because they keep me full and are an easy way to ensure I’m getting enough protein!

A couple of months ago, I randomly commented on one of LEANFIT’s Instagram posts and they kindly offered to send me some of their protein to try.

I tried three of the LEANFIT protein powders, the organic plant based vanilla, naturals vanilla whey and naturals chocolate whey. I drink all of my protein shakes with just water protein powder so there wasn’t any other flavors masking the true taste of this protein powder. My favorite was definitely the vanilla whey. The chocolate whey was a close second. The organic plant based vanilla protein was not my favorite. I may not be the best judge of plant based protein because I haven’t had many plant based proteins in the past but I could definitely taste some earthy flavors when I had the plant based protein. It almost had a after taste that reminded me of fresh garden peas.

I loved how easily this protein mixed in my water, often with protein powders despite shaking and stirring you end up with big chunks of protein. Honestly, there were 0 chunks to be found in my protein shake. LEANFIT protein isn’t an overly sweet protein powder which is a good thing because generally the sweeter they are, the more artificial they taste and the harder they become to stomach. I also didn’t find the flavors to be too strong or artificial tasting. The chocolate wasn’t a “in your face” deep chocolate, more like a light, not overly sweet, milk chocolate flavor. I actually look forward to my protein shake every day and I enjoyed the taste of this protein.

Protein powder is all about convenience. Basically you just scoop it into a cup and mix it with water. You can get fancy and add things like spinach, bananas, ice, almond milk, fruit, PB2 powdered peanut butter or regular peanut butter and blend it up. When you add other ingredients such as fruit or vegetables you also get extra micro-nutrients so that’s a plus. I’ll mention you can also bake with protein powder. You can see some creative recipes and ways to use protein powder on the LEANFIT website. This protein powder lasts for quite a long time stored in a cool, dry place.

The cost of this protein is quite reasonable, $39.99 Canadian for a huge two kilogram tub. That’s less than a dollar per shake. If you think about your breakfast for work everyday being less than a dollar that’s pretty reasonable. You can find cheaper protein powder options as well as more expensive powders but when I consider the quality of this shake I would pay the 40 dollars for a tub.

This protein powder is made of “high quality whey”, whey is a protein that’s derived from cow’s milk. Whey is called a “complete protein” meaning it has all of the essential amino acids the body needs to function. I have found that protein benefits me in weight maintenance, keeping me full, curbing cravings and also muscle recovery. One scoop is 130 calories, 25 grams of protein, one gram of sugar and two and a half grams of fat. It’s sweetened with Stevia which is AMAZING! I feel way better drinking something sweetened with Stevia as opposed to Sucralose. In summary, you’re getting a ton of protein for very few calories and very low fat.

I enjoyed this protein a lot, I found it easy to digest and it did not upset my stomach. My brother in law also said he really enjoyed this protein powder and found he could digest it easily. One thing to be cautious of with protein shakes is their ability to cause gas, bloating and indigestion and this did not seem to cause any of these for me. I have experienced all of those side effects with other proteins so I’m not immune to them. I think this protein would be enjoyed most and taste best if it were blended with ice, some almond milk and maybe a little fruit and yogurt.

Taste: 7.5/10 (for a protein shake)

Cost: 8.5/10

Convenience: 10/10

Nutrition: 9.5/10

  2. Hey everyone, I just bought the Leanfit sport protein isolate & collagen vanilla bean flavour and can’t stand the taste 🤢 then I went back to try another kind and bought we see plant based Vega vanilla says great new taste & smoother texture…. 🤢 💩 it is way more gritty then the other. But those were my only choices at Costco, so disappointed that I spent over $100 and it might go in the trash can!!!!!!

  3. Hi there
    wondering leanfit just whey will help a skinny person to buildup muscles? i know daily exercises should be added for muscles build up!

    • Hi Peggy! A high protein diet will help gain muscle so yes this will! But you also need to eat more (not a super low calorie diet) muscle combined with exercise.

  4. I absolutely love Leanfit Whey Powder. Drink two a day for optimum protein. Sometimes I make a tasty shake..add a banana and frozen cherries. My only wish…I would love to have a strawberry flavor.
