OK @pinknsparkly, here are my answers to your questions. Other posters may want to make their own contributions!
I need to eat more fruit (vegetables alone don't have enough nutrients and I need the ones from fruit too)
Which nutrients does she mean, specifically? I would argue that you can get just as much positive nutrition from vegetables and salad as you would from fruit – and, of course, without the sugar. That said, it’s only the first two weeks when you can’t eat any fruit on Bootcamp, and after Bootcamp you can increase the amount of fruit you eat, if you want, as you gradually increase your carbohydrate intake.
I eat too much red meat, and it will increase my risk of cancer (should replace with fish, chicken and beans/pulses)
This is based on studies that have lumped processed meat in with red meat, and the findings are still the subject of much controversy. Have a read of this article:
from The Guardian
To reduce the amount of fat in my diet (milk should be skimmed, no double cream, butter should be replaced with low fat margarine etc)
Did she say why she was telling you this? Did she suggest that fat links with heart disease? Because that has been proven not to be the case – worse, the assertion that it is, is based on flawed science from back in the 50s and 60s. (Gary Taubes, The Diet Delusion, explains this very well)
A low carb diet is a high fat diet. There is no issue with eating fat – it doesn’t make you fat - and you certainly should be eating low fat margarine, as that is an ultra-processed food!
Must eat carbs (by which she meant pasta, potato, rice etc, not vegetables) with my dinner at an absolute minimum, and ideally with all meals
Why did she say this? There’s no need for you to eat these foods – you will get plenty of carbohydrate from vegetables and salad, as well as more nutritional benefits.
No more than 100g cheese per week (and should be low fat)
I’m assuming this is because she thinks fat is bad. Definitely don’t get low fat cheese! We do recommend that people don’t simply binge on cheese, on Bootcamp, for two reasons – first, some people find that dairy products cause their weight loss to stall. Second, you can eat an awful lot of extra calories this way. And although we don’t count calories on Bootcamp, you still need to be mindful of what you’re putting in your mouth.
Carbs should be brown/wholemeal rather than white
Makes no difference - they're still carbs!
sugar free fizzy drinks are recommended as they're low calorie....
They’re also full of artificial sweeteners, which we’re aiming to avoid – and we’re not trying to go low calorie either. The Dr Andrew Jenkinson book will explain specifically why trying to follow a low calorie diet is detrimental, in the longer term, rather than helpful
should use low fat margarine rather than butter
Absolutely not! Margarine, never mind low fat margarine, is ultra processed and is as far away from being a natural food as you can get.
I have implemented some of these changes:
switched to skimmed milk (I don't use milk much to be honest, and it seemed like a sensible thing to do given how much milk and cereal my husband consumes)
No! Low carbing is about high fat. If you’re drinking milk (which you should be keeping to a minimum, as it is quite carby), then it should be whole milk.
swapped to brown bread (again, I don't eat this but my husband was willing to switch)
From a carbohydrate point of view, it makes no difference if you’re eating white or brown bread – you shouldn’t be eating it!
reduced red meat consumption and replaced with chicken and fish (haven't added in beans and pulses as I figured they're too carby?)
Really no need to do this – although more chicken/fish would be fine, and perfect low carb food. Beans and pulses are out, though, for the 8 weeks of Bootcamp, as they’re too carby
didn't order any double cream in the shop last week, and limited myself to one pot this week
Although you may find you need to limit dairy, if dairy doesn’t have a negative impact on your weight loss, then there’s no need to worry about it. And double cream makes some perfectly luscious low carb meals!
tried to order a light spreadable butter online (butter mixed with water and vegetable oil) but it was out of stock and substituted with normal butter
Please carry on using normal butter!
attempted to eat less cheese, mostly by having fish or meat with my lunch salads rather than feta which is what I was mostly doing
Again, issues with dairy to one side, and being careful about much you’re eating each day, there’s no need to stop eating cheese at your meals. Dr Atkins recommends you stick to 3-4 oz cheese a day (75-100g), which is still a pretty decent portion.
I hope this helps - but as I said earlier it is, of course, entirely up to you which course of action you feel most comfortable following.
