Yes, there are a million other factors and components of your diet and workout that play important roles in successfully, permanently and efficiently getting you to lose fat (while also maintaining lean muscle mass and being healthy), and a million ways to go about creating that deficit in a way that is as easy, enjoyable and sustainable for you as possible.
As far as the measurement, yeah, those scales are garbage – but since it spits the data out, I figure I might as well right it down. I did a caliper test when I started and it gave me pretty similar results, but who knows. I am taking photos every week for my main source of tracking. I can see the progress there – and can definitely tell I have a lot of cutting yet to do! I’ll keep on pushing, I don’t know if I can hit 10%, but I will try for 12%.

‘If your body fat gets too low, your body will need to find alternative energy sources – and will start to eat your muscles.’ How to tell if you’re teetering on the edge? ‘You’ll feel tired, headachey and weaker in your workouts – watch out for not being able to lift as heavy as you used to. It could be a sign that you need to put some fat back on.’

The most recent version of the Atkins diet is by far the most nutritionally balanced. For the first time, the Atkins diet has placed an emphasis on the kinds of fat being consumed instead of allowing all dietary fats. The monounsaturated and polyunsaturated fats are now emphasized over saturated and trans fats. The diet has also changed to allow "good carbs" instead of severely restricting all carbohydrates. These foods provide fiber, vitamins, and minerals that were once lacking in this diet. The high amount of protein will be beneficial in keeping you full. Research is clear that protein has a positive impact on increasing satiety, which means that you will feel full between meals.

What I mean is, any diet that actually causes you to lose fat did so because it caused you to create a caloric deficit. That’s a fact. There is literally NOTHING else that could possibly make it happen. This is the most basic proven science of the human body. Calories in vs calories out (aka the law of thermodynamics) is ALWAYS the basis for fat loss (or gain).
Shaping is a behavioral technique in which you select a series of short-term goals that get closer and closer to the ultimate goal (e.g., an initial reduction of fat intake from 40 percent of calories to 35 percent of calories, and later to 30 percent). It is based on the concept that "nothing succeeds like success." Shaping uses two important behavioral principles: (1) consecutive goals that move you ahead in small steps are the best way to reach a distant point; and (2) consecutive rewards keep the overall effort invigorated.
I have one question though. I think I’ve read most of your site at this stage and I think I can find most of the answer to my question but I can’t seem to find the complete answer and it would be nice to see it pulled together in one place. Now I understand the whole calorie deficit thing & I understand that you can create the deficit through diet & exercise. I also saw your article saying that, although weight training does have *some* effect on weight loss, its actually very small. I’ve also seen you virtually dismiss (:-)) cardio. The thing is, I haven’t seen all these things drawn together in one place. So: are you saying that changes to diet has BY FAR the greatest effect on fat loss? And that weight training and cardio have such a small effect on fat loss that, relative to diet, they are almost insignificant? Because that is the impression I’m getting. Actually – and I know this is not really possible – could you quantify their relative effects as you see them? e.g. diet 70%, cardio 20% weight training 10%. Again, I know, that’s not possible, but just to give a “feel” for their relative impacts. You can see what I’m getting at here: I’d like to get an idea for where to concentrate my efforts.
