Op I don't think your diet is particularly healthy although it's not terrible compared to what the majority of the population eat.
Not enough (natural) fat or protein imo, but then again, I eat the way your DH wants to eat, and I have done, for many years- Lchf/paleo. Common misconceptions about Lchf/paleo/primal diets is that they cut out entire food groups- they don't! Example, I don't eat grains (well, except rarely a bit of rice), grains are not a food group, they are part of one (carbs), and other, less starchy carbs such as veg and leaves provide all the fibre you need (another misconception, low carb diets have no fibre).
While it's true that our bodies use glucose, they actually have no "essential" requirement for any form of carbohydrate as we can synthesise our own - the same can't be said of fats and proteins, a lack of the essential ones (the ones we can't synthesise) will lead to illness and potentially even death, and yet, according to much official advice, fat and protein should be minimised in the diet and carbs are lionised. I'm sure that has NOTHING AT ALL to do with the historic (and continuing) influence of powerful processed food producers in the formulation of the guidelines, and in funding training for HCP wrt various conditions caused by the diets they are promoting!
That's my Monday morning rant out of the way, I'll on my hard hat and step aside 
For me -
B- coffee with double cream and left overs of last nights dinner (protein, salad leaves), or nothing but the coffee as I usually fast till lunch.
L- wild salmon sautéed with half an avocado (yes, you can fry avocado!), served a large mixed green salad, or other similar seafood dish.
D- roasted/sautéed meat or fish with Mediterranean style roast mixed veg and size salad.
Snacks, fruit (berries usually), dark chocolate, nuts, cheese, coffee with cream.
Plenty of green salad leaves with every meal, and lots of different colours of veg for variety. Courgette "noodles" are great.
30min intense exercise every day + a good walk- because it's not just diet, exercise is very important too.
(I've lost a very large amount of weight and gained a lot of health this way over the past decade)
