The problem with "lifestyle" approach is that you can happily gain weight on Paleo, Atkins, gluten free, Vegetarian or whatever healthy life style you choose if you burn even as little as 50 calories per day less than you consume. Most people lose weight initially either because of novelty factor of a lifestyle diet that excludes certain food items or food groups or because they switched from really bad food choices. For some people that is enough to find the balance and stop gaining weight. For some it is not. All the extra weight that I am carrying and trying to lose was gained while eating healthy and in moderation and while being relatively physically active. Still for me that is not enough. Hence I am trying to combine both approaches. But glad that it worked for you.

I guess that is the inherent problem with any diet which is by definition 'different', its so hard to maintain it as a lifestyle, and lets face it as overweight people that's what we really need is a lifestyle, not a diet. reducing carbs in favour of protein makes an awful lot of sense to me, same as counting the calories, protein, fat and carbs in what we eat - getting the macros right and getting used to living that way hopefully teaches us how to live our lives for ever, not just while we are on a 'diet' than get back into the old habits that made us overweight in the first place.

I actually do better with certain food mixes like eating 1/2 a cup of cottage cheese with a cup of diced veggies. Or my spring mix salad with chicken, walnuts, cheese and a drizzle of BBQ sauce. So between the protein and large array of veggies with some healthy fats is what is keeping me feeling full and keeping me slim.

Personally I never use the processed foods, It's a money making business and the longer you stay eating them, the more money they make.
When Atkins first started and had no products available, they claimed that even a piece of chewing gum could stall weight loss. So why now do they allow their products on induction or throughout their weight loss program? One answer $$$$$.
