Some good ideas in the video but there is far too much emphasis on calorie counting, we need to consider the source of the calories. Most of the calories in the menu come from simple sugars in the sweets and pasta, I'd like to see more calories derived from oil and protein rich foods. Slow release carbs are useful for keeping you warm at night, Mars Bar derived calories not so much! And when comparing weights with the expensive boil in the bag ready meals we need to consider the whole cooking, eating, cleaning process. The only things I like about the ready meals is the fact that you really can't get the recipe wrong (just add water) and there are no pots to clean. When cooking Mash etc there is the extra cleaning kit and fuel to consider so whilst BITB meals are spendy they do have a few good points. I'd also need to add some roughage to the menu shown or I'd be needing some powerful laxatives!
@imagedude - a large proportion of the carbohydrate calories are actually complex carbs (pasta, cous cous, smash, oatcakes and the oats in the granola). The white pasta that I had in the bag in the video is 69.6% starch and only 3.5% simple sugars. If there is not enough roughage, just replace with wholemeal pasta (which I generally eat at home anyway) but note it has lower calories for the weight. It does, however, have more of the B-vitamins you need to burn the carbs properly.
As for calories from protein - the amount of energy your body can derive from protein in a given time period is limited by your liver's ability to turn amino acids into usable energy. You can only convert roughly 300-400g of protein into energy (basically your liver converts it into carbs plus urea) in a 24 hour period. This translates to 1200-1600 calories per day.
As for keeping warm at night, protein-rich foods are actually better than the carbs you suggest. The process of breaking down proteins, while not delivering a huge amount of calories, is relatively hard work for your body and is thermogenerative It partly explains why many northern peoples traditionally had higher meat contents in their diet compared to more southerly peoples.
You can read more about the net calories extracted from food and the thermic effect of food here:

That said, protein heavy meals tend to leave you feeling fuller for longer (presumably because they take longer to digest), so it's a balance between getting the energy you need and feeling sated by your meals.
As for ready meals, I don't like the Wayfarer types due to the water content and low nutritional value (by any measure - macronutrients or micronutrients) for the weight. I accept your point regarding washing up, however, and do indeed use dehydrated and or freeze-dried pre-prepared meals for some trips.
Readers/viewers should remember that the proposed menu in my video is answering a specific question - how to get a week's worth of food in a side pocket - and it is doing so in the context of equipment packed for woodland living/bushcraft in the northern temperate or boreal environment with the presence of trees. Therefore I'm working on the basis that their will be no shortage of either fuel (i.e. firewood) or water. Washing up then is not an issue.
If I were undertaking a ski tour (such as the one I completed in Norway in March) above the treeline or a multi-day backpacking trip (such as the Scottish 4000s trip we completed last month), where I had to carry a stove and fuel, the balance of what I pack and how it is prepared changes. Imagedude is right to point out these considerations in the wider context. Personally I use Expedition Foods and/or Real Turmat but those cost around £10 per main meal, which makes it an expensive option for most people.

As for the healthiness or otherwise of the diet. We can probably debate that until the cows come home. Even researchers and medical professionals cannot agree on what is healthy and what is not. That aside, this is one week's worth of food. Regardless of what you eat normally, a week of dehydrated food will not kill you. What will kill you is trying to carry a weeks worth of fresh fruit and veg on your back (said somewhat tongue in cheek). But you get my gist, you often have to make compromises on trips - more so on hiking trips, less so on canoe trips.
Personally, I'm in the woods a lot and, like when I'm at home, I try to eat as much fresh food as possible when teaching out of a fixed camp. I couldn't eat the diet featured in my video all the time either but that's not what it's intended for. But when I need to carry the food I need to keep going in minimal space and for a limited time (and on a limited budget) the side-pouch menu featured works well for me.
I hope that this adds some colour and context to the aims of the blog.
Thanks to everyone for reading/watching and generating such a stimulating discussion.
Cheers,
