Does the heat of coffee break down whey protein? Is the protein just as effective if mixed with hot coffee?

>>>>Does the heat of coffee break down whey protein?\n\nIt denatures the protein, which is not excatly the same thing. Think of a dentured protein as being like a crumpled pecie of paper. It's still in one piece but it can't be used for anything in that shape. I doubt if the heat of coffe would be enough to break down the protein, as in physcially break it to peices, at least not in the few minutes that it normally stays hot.\n\n>>>>Is the protein just as effective if mixed with hot coffee?\n\nIt's just as effective nutritionally, IOW it makes no difference if you just intend to eat it. It will be pretty useless chemically, ie if you want to use it for chemical reactions.

Caffeine by itself doesnot raise Insulin levels - sugar in your coffee will.\n\nWhen sugar enters the blood stream, insulin is secreted by the pancreas to convert the extra glucose into glycogen and fat.

I take two 50 gram whey drinks per day and for my Casein at night I use GROW.  I've tried several types of casein and GROW tastes and works the best in my opinion.  I have the chocolate flavor and I think it's 20g per serving.  It's not bad with water and it's really good with skim milk.\n\nSometimes if I have a really hard workout in the mornings I'll mix a serving of GROW with my whey so I get that benefit of the whey right away and the casein is slowly being absorbed throughout the day.  \n\nGood Luck!

microwaves cause water molecules to vibrate which heats the food contained.  So heating things in microwave does not destroy the nutritional value.  For your protein power it may cause it to denature...but that would happen in your stomach anyways. so i would say you are OK microwaving your protein.

both you have to be hydrated prior to get nutrients pumping through while you work out and its also good to drink water or watered down whey protien isolate during your workout to keep the amino acids comming.  but for drinking water after I use the method of weighing yourself prior to working out or cardio and then after and drinking 1L of water per lb you lose in sweat.

Yeah, it's kinda risky. Just stick to whey protein.

No but the sugar and cream you put in it can give you calories that can that can turn to fat. I've done the South Beach diet before and they suggest putting powdered cream and a sugar supplement in your coffee to cut down on calories. I prefer Sweet 'N Low.

The protein and alcohol have very little to do with one another really, but consider this.... alcohol is a lot of empty calories that you will have to work twice as hard to burn off. You are being counter productive to go work you butt off at the gym then turn around and get blitzed. You're cancelling the workout with those empty calories.

Yes, whatever you read is correct only.\n\nCarbs has got the protein sparing ability.\n\nIf you eat/drink only protein just after work out, the protein will be used to regain the energy and not for the building muscles. Well, to save the protein for builiding blocks it is mandatory to take carbs so that the carbs will be used to recover from the fatigue.\n\nHope you understood the matter.\n\nIf not you can write me.

Caffeine is in no way fattening. What i do is drink my coffee black with no sugar etc.. It only takes about 1 to 2 weeks to get used to the taste but once you do you will never switch back.\n\nBelieve it or not many bodybuilders drink Black coffee prior to competions. Go for it just do not add suger or any dairy etc...

I have for about two weeks, but it was not a result of whey protein.\n\nI started working out after a long 2 month break. I took whey to maintain the last of my muscle mass that could have been lost during re-entry into weight lifting. When you re-enter an exercise program, or start a new one, you tend to overstress your different systems, as well as your metabolism. The stress causes large secretions of cortisol, a hormone that when produced in excess, it will cause your body to catabolize your muscle tissue for fat production. \n\nThis causes a sudden drop in weight, but many times causes a loss of lean body mass. Once a new trainee's system adapts to the stress inflicted by the exercise, your hormones will then reverse the previous situation by promoting muscle growth and using the energy stored in fat cells for them.\n\nWhen growth hormones cause your muscle cells to reproduce, they will begin using proteins and carbs, as well as water, to increase the size and quantity of your muscles, usually resulting in a gain of lean mass.\n\nIf you are losing weight by taking in whey supplements, then you could either be using a very good exercise program that is causing massive fat loss and gains in lean body mass, or, you are on an unusual diet. If it is your exercise program, you should begin to gain weight at some point, but not size. This is an increase in lean body weight. If not, then you may be over exercising.\n\nAs for the diet, whey protein is generally directed towards those who are looking for gains in lean body weight, or muscle mass, and cannot consume enough protein in regular food without unnessential nutrients or high calories, or, they just want easy access to more protein. \n\nLoss in weight is expected in new exercise programs, but whey protein is designed to prevent or minimize that over time.

Whey protein is quite a bit better than soy protein for balance- The only reason a doctor would recommend any protein would be for a specific protein-deficit problem.  However, it is a good source of protein (of course, so is tuna), and numerous studies have shown it aids hair diameter and strengthening fingernails-not to mention weightlifting and recovery from surgery.

Protein contains nitrogen. When protein is broken down and digested, it creates ammonia from the nitrogen. Ammonia is toxic, so the body must get rid of it quickly. The kidneys convert the toxic ammonia into the less toxic urea, which then gets converted to urine.\n\nHigh protein just means the kidneys have to work harder. Many dieticians assume that working the kidneys harder could cause kidney disease. However, there have been no published studies which have shown high protein diets lead to kidney failure, even in competitive bodybuilders. You may want to also keep in mind that about 50% of protein ingested gets burned up as energy, so at some point with increased protein your $40 bottle of whey protein is doing nothing more than a couple of slices of bread.\n\nJohn

Caffine will excellerate your metabolism and therefore burn off more calories.....Not really a good diet idea tio drink cofee  just for weight lloss ...I used to drinks tons but contstant pee was not for mee.\n.....anyways I now drink 1-3 cup in morning and d1 diet soda in the afternoon and then if I'm going to exercise I drink a huge coffee......\nIt gives me extra energy for a workout.....without the calories of an energy drink like rockstar.......

it's okay\nconsider the low quality of the sweetener used, and the amount of sweetener, and the fact that milk is already more carb than protein by weight.  also milk contains saturated fat, and potentially contaminants.\n\ngood protein though, and long-term protein.  (some protein digests faster than other)  Also, it's convenient.  \n\nMy guess is that you should just drink the milk, and (sadly) probably not whole milk either.\n\nIf you need a sugar buzz eat quality fruit instead.

That is because heat destroys the structure of a functional protein.\nproteins are long chains of amino acids. This chain of amino acid folds up into a 3 dimensional structure via intramolecular forces. like you can fold up a long, blown-up balloon into a giraffe or a dog. With this structure, proteins are able to perform its functions. but when you heat the protein, you break the bonds in the amino acid chain, unfolding it and destroying its 3 dimensional structure. (IE, breaking the giraffe back to a long baloon, obviously it doesn't look like a giraffe anymore) and the protein cannot perform its functions.

Depends...\nAccording to the Food and Drug Administration (FDA) whey protein isolate is a natural dairy protein powder made up of at least 90% protein.  So if you are body building that is the way to go. However, whey protein is made from casein which is a milk protein so if you are vegan, whey is not an option. \n If your looking to lower your cholesterol and what not, soy is your thing. \n\nBut if your goal is to build muscle, loose fat, basically, if you have goals that are more excercise related, whey is definitely it.
