But I did some research that showed me the best whey protein for weight loss is actually a great tool for building lean muscle and burning fat.

What is whey protein and why is it good for weight loss?

Whey is the liquid produced during cheese manufacturing. This liquid is captured and converted into a dry powder with lots of protein, amino acids, vitamins and minerals that support lean muscle growth and fat burning. (1)

It’s technically still a dairy product, but it contains less than 1% of the sugar in dairy products called lactose. This is why some people with lactose intolerance can actually enjoy whey protein with no problem. (2)

Whey contains a specific amino acid called leucine. Leucine is a branched chain amino acid that is especially good at building muscle to burn fat. (3)

Leucine helps muscles recover from workouts quicker, so it’s easier to stick to an exercise plan and feel great. (4) Whey is also known as a “complete protein” which means it contains all essential amino acids to help with building lean muscle and repair. Building lean muscle is key in burning fat.

Ingredients to AVOID in your whey protein powder

  • 1. Ion exchange (degrades amino acids so you don’t get the health benefits) (6)
  • 2. Bioactive peptides (they can be overly processed and create free-radicals that age you and could even be linked to causing cancer) (7)
  • 3. Artificial sweeteners (such as Splenda, aspartame, and Stevia) can actually make you feel hungrier and undo the benefits of protein powder.
  • 4. Dextrose, maltodextrin, maltose, and sucralose (these are sneaky names for sugar)
