My only criticism of WLIs, if it an be called a criticism at all, is that there remains a huge risk that people will simply pile the weight back on when they stop. But there's no magic fix for that. We are just going to have to hope that, having lost the weight relatively painlessly, we all enjoy being slimmer and fitter with more energy and looking great in our clothes and having more confidence so much that we are hugely motivated to stay there and not ever allow things to get out of control again.
With a bit of effort and common sense it surely has to be easier to maintain a healthy weight than to achieve it from a starting point of obesity. If we can't at least manage that then we probably deserve all we get. But that's not the fault of WLIs any more than it's the fault of low carbing, or intermittent fasting or Slimmers World or anything else. You need to be mentally prepare to put the work in and change your attitudes and habits forever once your target weight has been achieved. It's not going to be easy but no-one ever promised it would be.
Oh, and a second critisicm of WLIs and this is a criticism, is that I definitely don't eat more healthily than I used to when I was fat. 😂I just eat much, much less in general, but it's certainly not better food. Frequently it's just junk. It's just fuel and I don't really care what it is.
My interest in cooking has disappeared so I take the path of least resistance with food. When I get hungry, I am suddenly ravenous and want to eat now so I eat whatever is to hand. I'll be done in six mouthfuls and push the plate away. If I buy a supermarket sandwich I'll eat half of it. But depending on where I am and what is to hand, it might be a pile of biscuits or banana or a McDonalds or a tin of ravioli. Something low effort and not always fresh or healthy.
Because I have little interest in food now, I struggle to meal plan ahead. I don't want to think about food, it's a chore. I get to the supermarket and wander around not fancying any of it. This means even if I've bought plenty of fresh ingredients because I know I should, I get to dinner time and I have no motivation to cook them. I'll often end up having a half a tin of tin of soup and some toast for dinner, instead of the interesting and freshly prepared meals with lots of veg that I used to make. I know this is terrible, but it is what it is. I try to make sure I at least eat a few pieces of fresh fruit each week and I am losing weight in spite of an often terrible diet, so I see it as a temporary blip that's helping me get where I need to be, even though I am aware it's less than optimum.
My fear is that when my love of cooking eventually returns, so will my appetite and my lack of self control. This is where I will really need to mentally prepare myself to transition back to normal life with no WLIs.
