Bottom line...it's calories that count. The whole premise of the "Low Carb" diets as well as the "Low Fat" diets from the 1990's is that one would eat less. Example - for low fat, originally one would eat a lot more veggies and fruits and lean protein, and for low carb one would eschew most of the processed high calorie stuff such as cookies, french fries, white bread etc. Of course what happened is that book authors, food marketers, and dieters tried to find ways around that - with Low-fat/fat free new products like fat-free/low fat cookies and ice cream and all that came out, and lots of folks bought and consumed mass quanitites because they were 'fat free' not paying attention to the fact that (for example) the caloric difference between, say, the Fat-Free Fig Newton and the regular Fig Newton was slight indeed...what was worse was that people who normally did NOT consume stuff like cookies and chips started buying and eating the fat-free stuff with (they thought) impunity. In fact, I remember a show on PBS called "Eat Smart!" back in the early 1990's that said point blank that the only reason sugar was bad for you was because it causes tooth decay!! (I'm SERIOUS!!!)
As far as low carb - same thing - the marketers started rolling out products and making up terms like "net carbs". I saw MANY posts from people eating stuff like protein bars (candy bars) and raving about how they had so few 'net carbs'. But when you look at the label, the calorie content would be the equivalent (or MORE!) of a regular Snickers bar. (let's not even GO INTO the price factor).
Sure, add more protein to your diet (BTW milk actually is higher in CARBS than it is in protein...) but more importantly, watch your calories and try and eat a balanced, healthy diet (a good place to start would be the new US Government Dietary Guidelines for Americans which can be accessed at
www.nutrition.gov) and get plenty of exercise - in other words, focus on permanent healthy lifestyle changes.
