Perhaps your current diet + healthy carbs would still help you achieve your goals?
I limit myself to 30g of total carbs (minus fiber) a day so it forces me to be more honest with myself. If I am at 25g for the day and I need to make dinner for instance, it basically forces me to always pick the low carb version of a meal (veggies + meat).
I hope to one day be able to transition to a diet with more healthy carbs, but in the process I am focusing on working on better habits and losing weight.
Personally, I found that about 35% gave me most of the same benefits people claim for the much lower carb diets, without the hassle of having to put a lot of work into food choice to achieve it.
At 35%, a lot of "ordinary" foods can be tweaked easily to fit. Sandwich is 50%? Get it with regular mayo instead of lite mayo, or make it double meat, or both...and you can get it to under 35%.
At 5%, that sandwich is right out. As are burgers, pizza, pasta...basically most of the mainstream diet is out, and since most food infrastructure is geared toward serving people on the mainstream diet, that can be a big pain.
But yes, food can be a pain (I have been craving pizza and fries for the longest damn time). My other goal aside from losing weight is learning what foods I _do_ like since having been a picky eater, means I defaulted to the mainstream diet and never strayed far from it which was negatively impacting my health and weight.
On the plus side, while it can be slightly more expensive grocery wise, it basically closes any eating out for the most part, so I can save money.
If I stick resolutely to a high-fat, medium-protein diet, I am almost never hungry and have plenty of energy. And after 7 years, it has kept 45 lbs of excess weight off me. I was never truly obese, but others have shed hundreds of pounds permanently doing the same thing.
How do you know that it spikes your blood sugar? Are you diabetic and actively monitoring?
Do you not have any food cravings on your regular diet? What marks the carb-induced ones out as different?
