If people had the self control to eat the same thing day in, day out with no snacks in between they probably don't have the same food issues that overweight people have.
Most people who work have defined breaks. They are the only times I eat or drink. Yes, it is a self-control thing, but no-one can do that for you - bizarre to take that as an excuse?
Also, dried fruit has a shit ton of sugar in it.
No more than the actual fruit itself. If I take 3 dried plums and 2 dried figs into work, the sugar content is the same as if I took in the whole fruit - only people for some reason applaud the one, but sneer at the other. Strange thinking.
I could say I could do the same thing with a 10kg bag of rice and lentils, and just eat dhal and rice for 2 weeks. More appetising
You're suggesting bland. None of this is bland - each nut and piece of fruit has their own taste and I vary what I take in, so it really doesn't get boring.
and I could feed the rest of the family too, but that's hardly helpful or sustainable for most people!
Only if you try to find excuses. By the way, wath what people take into work for lunches. I barely see any variety - the same people will have the same sandwiches, yogurts, fruit and veg in all day every day. Lack of variety is a silly thing to suggest as a reason not to eat healthier.
But of course, there has to be a will for there to be a way. Everyone can find reasons why not to do something.
