Is it possible to cut fat, while still building lean muscle?

Should I do these while in fasted state or not, and how will that impact fat loss and muscle building? This is the reason this website has been confusing people because of its focus on fasting. In caloric restriction, on a standard diet, insulin is being produced. When insulin is present, sugar is burned and fat is not.

When insulin leaves the bloodstream, the body is supposed to switch to fat. For someone with insulin resistance a great many people given our obesity epidemic , the body produces too much insulin for the amount of sugars consumed and, once the sugars are used as energy, forces the body to burn protein instead - because the insulin locks out the fat burning.

The reason why fasting and lchf don't have that effect is because they do an end run around insulin and keep it out of the picture. Simple caloric restriction does not do that, and thanks to the catabolization of protein, lowers metabolism. So caloric restriction results in loss of muscle mass because it doesn't control insulin and fasting does not result in loss of muscle mass because it controls insulin.

I have a question; i just started the intermittent fasting last week and is great! A protein shake would definitely break a fast. Most people find they don't need to supplement anything to incorporate exercise. Also watch out with the shake as many have artificial sweeteners and other ingredients we recommend avoiding. Keto is moderate protein and incorporating the protein shakes may make your protein intake too high.

So you can lose weight fat and add muscle mass with the correct combination of exercise and macro-nutrients. We do it all of the time.

So, to lose weight on hflc I assume that I burn the fat I eat, before my stored fat to lose weight, so when burning body fat I am still restricting calories? Replies: 3 , 4. Reply to comment 2 by Patrick. The fat you eat in a meal say 30g will go to mostly to fat, muscle and liver tissue to storage for later use. If you restrict the fat on a low carb diet, your body will see it as a signal to "shortage of food" and, in response, may slow you down , saving your fat stores It would be good to see an explicit debate between Jason Fung and Stephen Phinney, on extended fasting especially.

Reply: This is dumb as shit. So fasting is muscle preserving because of evolution, that makes perfect sense. Replies: 21 , 24 , David and Nicklas, After reading your moronic messages, I felt the need to address your ignorance because it doesn't look like the owners of this website respond to people's comments. You can eat all the protein in the world, but if you don't exercise it won't do diddly.

Regarding fasting I highly recommend fasting. Naysayers don't know what they are talking about. Reply to comment 5 by Robert. Robert, You asked, "How does extended fasting beyond 24 hours on a regular basis, help or hurt a healthy individual, in the long run? There is no way anyone can say that your diet doesn't affect muscle gain. There is solid evidence that your body need the proper nutrition, calories and protein amount to gain muscle as well as other nutrients to help your body break down this protein to fuel your sore muscles after a workout to help them rebuild so please.

Sure you also need to workout and exercise but you will NEVER gain muscle if you workout and not eat protien. Please gain some solid evidence before you publish this work that is easily proved wrong by many others around the world. Dr fung Please reply.

I have lost about 50 lbs and dropped 3 inches off my belt in 43 days. None of my resistance training or cardio has suffered, all volume and weights has stayed same or gone up. I have about 30 lbs more to go, and this article has just psyched me up to see this through. This article was written by an extremely intelligent person. I am sick of all the "bro science" about how you lose lean mass when fasting and how it is so dangerous. Like this great man says, it is bs. Our bodies were made to fast. Thank you so much for writing this article and all your other works. You truly are a god among insects.

I have a question in this regard. I understand that fasting won't cause me to lose muscle on it's own, but how will it impact muscle building? I'm trying to lose weight, but also gain muscle mass, so I work out at the gym 2 times a week.
