Sinday? Sounds like fun.

As long as you're eating adequate protein, you should be fine. Studies have show that the best way to preserve or increase muscle mass during weight loss is the combination of low-carb, adequate protein, and exercise.

If you're just starting out with low-carb, it'll take a few weeks to adapt. It's often recommended that you take a break from exercise during that period.

High intensity / Cardio workouts might make you suffer a bit more due to the electrolytes you'll be struggling to maintain, and other general confusion in your system, through your adaptation period. Just don't get frustrated if you try your usual workout schedule and can't perform as well as expected. It'll come back!

I found I was able to do very high intensity training and lift weights for months while eating this way. I usually did cardio 6 days, strength 6 days alternating body parts and only rested one day. I lost an average of 10 lbs per month and gained and toned muscles.

I did much of my cardio: spin, crossfit, HIIT fasting followed with bacon and eggs for breakfast. Strength training was usually later in the day so I had eaten.

It can be done. Listen to your body though.

Hello @kiely32

What Wab mentioned is very true.

The first couple weeks are about getting used to lower carb

After that you can start conditioning your body to burn fat as fuel

Google Mitochondria and endurance exercise

Your body tissues will physically adapt. Not a diet thing but a biology thing. Your mitochondria will grow and adapt to burn a higher percentage of fat along with glycogen

I have been doing a long term experiment to just see how hard I can push my body in
That regard.

So far I have been able to ride 30 miles at 17+ mph on my bike and do it fasted and on low carb with no real exercise hangover.

I did crank out 43 miles one day that was way too hot... Like 98 out. I had two packs of electrolytes in 100 calories each pack.

It was about 2700 calories of burn off with 200 calories of carbs in, and the rest from fat.

I do eat serious protein. As Wab mentioned it also can let you add muscle

Just have to get enough protein.

I would not push it too hard too soon though

I only do 3 hard rides a week. If trying to cycle in lifting I cut back to twice

Hang in there and get the first three weeks down. Then push yourself twice a week to see what you can do when fasted

It will amaze you in a month how different you can feel

Best of luck

Not sure if you read Reddit, but I came across a group called Ketogains. And it's all about people on Keto who are building mad muscle. I would recommend checking them out.

Thanks for the response guys. Really helpful. I have a metafit class in the morning so I will have a pretty good idea after that how it is affecting me. I will take it easy if need be. I can't wait to get out of this fat suit as I am sure there is some serious muscle under there! I am a little concerned I am eating too much protein... My diary is open to friends so if you add me, or are my friend and you want to take a look you can. All I know for sure is that I can't remember ever feeling this good! :-) Thanks again for the advice and support.

From what I've learned from the group here, you don't need to worry about going over on protein. I had previously read that it can effect ketosis, but after doing more research and getting info from our more experienced members, apparently it's not anything to worry about. Especially if you're working your body as you do. You need a good amount of protein.

@KittensMaster... As a fellow 50ish cyclist, I just wanted to note that 31 miles at 18.8 mph - Now, that's pretty cool.

I haven't ridden my bike all summer. I have a nice 16 mile loop that I like to do. I usually finish it right around the hour mark. I wonder if I could do that pace right now.
