How Does Whey Protein Affect Fat Loss and Insulin:

Yep, whey protein can cause an increase in insulin, just like sugar! Learn about how it works! http://www.thomasdelauer.com

How does whey protein affect insulin and fat loss? Isn't whey a protein, not a carb??

Effect of Whey Protein on Insulin

Whey is one of the two main proteins in milk - the other is casein. Whey, like all proteins, is made up of amino acids, the building blocks of protein. When we consume protein, we then break down these amino acids and use them for muscle growth and tissue repair.

Whey contains all three BCAAs along with all of the essential amino acids.

Whey is highly insulinogenic - consuming whey leads to a sharp increase in insulin levels.

This response does not have to do with blood sugar levels - when a food has a high glycemic index, consuming it will cause a large increase in blood sugar levels. In response to this, the body produces insulin to combat the high blood sugar and allow glucose to enter our cells for energy. This is not what is happening when we consume whey - insulin release is responding to amino acids, not glucose levels.

Insulin binds to cells to allow them to take up energy, which can be glucose or amino acids from proteins. The amino acids in whey cause an insulin release. Whey also leads to the release of GIP and GLP-1, two gastrointestinal hormones that also raise insulin levels.

This increase in insulin is actually a good thing! Whey is a fast acting protein, and the spike in insulin allows amino acids into the muscle cells to encourage repair, helping us to gain muscle and heal quickly.

Consuming whey protein has actually been shown to lower blood glucose levels when consumed during or directly before a meal. A 2005 study in the American Journal of Clinical Nutrition found that when whey was combined in a high-sugar meal, individuals with type-2 diabetes had a lower blood glucose level following the meal than if no whey was consumed. This is thought to be because the increased insulin aided the body in glucose digestion.

Generally, the better the whey, the higher the insulin spike and thus the more effective at delivering building blocks into the cells for the purpose or repair and growth.

Best to consume whey directly following exercise. It is quickly broken down and made available to muscle cells for repair post workout.

Whey protein isolate contains 90% protein and thus has less lactose, fat and cholesterol than whey protein concentrate. To get the most out of your protein, go for the whey protein isolate. You will experience less bloating and get more of the benefits - lean, ripped muscles.

Too much protein is dangerous, so be sure not to consume excess protein. Excess protein can lead to increased fat storage and calcium loss, which can lead to osteoporosis.

    What about bone broth protein like Ancient Nutrition? Getting very confused on plant vs animal protein. I fall short on protein in my macros all the time and trying to run a way to correct that some days.

    He didn’t explain the effects properly in simple terms so I will, remember Thomas is just learning from the internet like most of you guys.
    All foods cause an insulin release, although whey protein does cause an insulin release it’s only a very short sharp peak then it settles down.(this is needed to absorb all nutrients)like a bus shuttle.
    With high glycemic carbohydrates they cause a long lasting insulin spike.(and are more damaging long term)
    The other trick is to stimulate muscle mass increase and repair you need a minimum of 40-50 grams of whey or good quality protein (animal based the rest is shit don't listen to vegan bullshit)every 4 hours.Anything less wont do it and fasting does not increase muscle at all ,it only slows muscle wasting by increasing HGH.(but not enough to get buff on it)

    In this video he says the insulin spike isn't bad but then in another video, he discredits whey because of it

    As a type 1 diabetic teen who is female, 157 cm tall/45 kg light, I’m trying to use whey to boost my workouts to build up some muscle— and I can confirm that it does raise my blood glucose which I use to my advantage to lesser risk a low blood sugar during exercise and being a type 1 I don’t produce insulin..so.. xD

    Add cream to your whey. Don't fear omega-6, eat eggs because they are the best omega-3 and omega -6 combination. The biological effects of the omega-6 fatty acids are largely produced during and after physical activity for the purpose of promoting growth and during the inflammatory cascade to halt cell damage and promote cell repair by their conversion to omega-6 eicosanoids that bind to diverse receptors found in every tissue of the body.

    Do we need to consume protein shake in order to build muscle? Is it harmful or not?

    02:46 so what happens to all the glucose shuttling inside all kinds of cells over and over again and again;
    i suspect inflammation
