Struggling to maintain blood sugars

30 mins of intense cardio hr above 150, plus weight training for around 20 mins 5 times per week with a swim after usually 2 days per week, have been eating low carb for around 1 year, usually cheddar cheese and around 5-6hrs between meals. I am 27 and am probably fitter than I have ever been was diagnosed around 2 years ago and have shifted about 4st in weight since.
 
Wow, congrats on that weight loss. Excellent!

Do you test before and after exercise? What are your glucose levels then?
 
Thanks. I used to test before and after but usually test after I get back from work, they used to rise during excersise and immediately after somewhere between 8-12 and then crash down to around 5 about an hour later however the crash down is not happening. I eat around 100g of fat per day made up usually of the fish in the morning and omelette at lunch time.
 
Sweet potato? That is 17 percent carbs - far too high for me to consider eating it - are you actually weighing your foods and calculating accurately or just hoping that you are under 50 gm of carb per day?
Are you including enough fat to ensure that you don't break down protein?
 
@Farmer234 that's really helpful information. So here's what I think may be happening...

Because you're not adding fat to you diet in addition to the fish and eggs, your body wants more calories, so if you won't give it more calories in the form of healthy fats, it will demand it though the starchy carbs. Same thing happens to me. I actually have to eat pats of butter sometimes, only the best of course, and organic too. :)

You come across as a very disciplined person. Very impressed with your daily regimens.

I'd love to be more like you. :)

Have you lost all the weight you need? If you have, because you no longer have fat reserve to draw from, you'll need to increase fat intake. Does that freak you out? I know it's really hard to push through our fear of eating more healthy fats. It was really, really hard for me.
 
Everything is calculated through my fitness pal. Will try increasing fat intake and see what happens across the next week or so.
 
Farmer,

I've been to see my doctor today, long story short. I've been concerned that my morning readings are slightly higher than my last readings before bed. He saidwas nothing to worry about, but if my readings start to rise without an explanation, then he wants me straight back... There might be a reason for your levels to rise and perhaps a trip to see you doctor can sort it out.
 
@Farmer234 - Given your age, I'm suspecting even more that you may have LADA with possibly a long "honeymoon" that is now wearing off. You need to see your doctor and get the c-peptide test that @chalup recommended to find out what is going on with your endogenous insulin production.
 
Sounds good.

Healthy fats - (my hope is that if you increase fat, you'll decrease your need for the starchy vegetables...

raw nuts
avocado
3 large green olives, pimento removed - (I like mine stuffed with a clove of garlic)
leafy green salads topped with a oil and vinegar vinaigrette: 2 Tablespoons Extra Virgin Olive Oil, and 1 Tablespoon of your favorite vinegar. I use a variety of spices too. Oregano, salt, pepper, experiment.
Avocado and raw nuts can top your salad too.
If you don't like vinegar, you can use freshly squeezed lemon juice instead.
Pats of extra butter, coconut oil melted onto everything, meat, eggs, vegetables.
You can also add extra virgin olive oil to foods after they're cooked.

What am I forgetting?

Hard cheese are fine but it's also has protein too so watch it.

This is really important. Excess protein at any meal converts to glucose. I really encourage to you try reducing your protein intake, test before and 2-hour post meal and see what happens. Testing is the only way you're going to figure this out.

Above ground vegetables...

As much as possible stick to with above ground vegetables, but not too much. Also, note that some vegetables are higher in protein than others, which also can spike me. In the beginning, I had the most trouble with broccoli, brussel sprouts, green beans, and peas gave me the most trouble.

Trying to think of vegetables that gave me less trouble... broccoli, brussel sprouts, green beans and carrots were fine if I at them in much smaller amounts. Cauliflower, red and green pepper, asparagus were all fine. Onion in small amounts, zuchinni (corgettes) in small amounts, were both fine, but again only in small amounts.

Fresh red cabbage cut in chunks, celery, mushrooms, were all fine too.

Any starchy root vegetables were a problem, still are. For a long time I could only eat small amounts of carrot and cherry tomatos on my salad.

Dinner to Breakfast time interval...

If you can increase this to 12 to 14 hours, that will give your pancreas time to recover.

Skipping breakfast...

An alternate way to increase the time between dinner and breakfast is to skip breakfast by starting your day with coffee or tea and some fat that doesn't contain protein.

Might be worth revisiting the low carb page on Diet Doctor too... https://www.dietdoctor.com/low-carb

You may not be in ketosis. If that's the case, you'll feel hungry a lot of the time. Some people need to be in the 30 - 40 carb range to be in ketosis.

If you're not having to increase your water and salt intake, that's a clue that you're not in ketosis, particularly with your exercise regimen. Also, hunger levels drop too when I'm in ketosis.

Sure would like to know what happens with your glucose levels over the next few days. Fingers and toes crossed the problem is the ratio of of macronutrients you've been eating. My best guess is that fat needs to be increased, protein needs to be decreased, and carbs need to be decreased. Keep asking questions and trying different strategies until you find what works best for you.

You may be right. Couldn't hurt to get tested. In the meantime, he can continue to make adjustments and see what happens while he's waiting to see his doctor to get tested. If he's LADA or type 1 in the honeymoon stage, making these adjustments in his diet will still help. :)
 
Yeah diet is mainly based around meat fish and veg and fats like cheese. Looking at around 131g of protein per day, usually les than 50g of carbs
Hi again. 131g protein is a lot. The normal recommendation is 0.8g/kg target body weight, so it depends on what you are trying to achieve. Anything over 70g/day raises both my weight and my bs, over 100g would be very problematic for me, but we are all different!
 
I find my blood sugar goes up a lot if i eat too much protein, it doesn't show up as a spike that day , instead i get what looks like a much bigger morning liver dump which persists for longer and which sits on top of higher fasting blood sugars overnight . When i get the combination right - which for me is protein and carb combined of under 100g , i can have fasting blood sugars around 4.5 and average of 5.0, too much can convert that to 6.5 and 7 in a day . Also eating after about 6 pm does the same thing . Your protein level look very high to me .
