Some of the weight loss articles out there these days are getting a little nutty. New scientific studies that shed light on how metabolism works are wonderful and valuable in their own right, but when findings get morphed into magical new “tips” for losing weight, something’s amiss. Some recent pieces in prestigious journals, which have sought to dispel the myths of weight loss and of the individual diets themselves, suggest that the medical community is also getting tired of the hype and the unfounded assumptions that permeate the public discussion.
The conclusion? A caloric deficit is the sole cause of fat loss. Even if those calories come from the shittiest sources known to mankind, fat will STILL be lost. It’s not the source or the quality of those foods and the calories they provide… it’s the total quantity of it all. (Additional details here: Is Sugar Bad For You? How Much Should You Eat A Day?)
Everyone knows that good things come to those who wait, but sometimes you don’t want to wait. Like, for instance, when you’re waiting for the number on the scale to creep down, whether it’s because you have a big reunion in a month, you’re headed to the beach in just two weeks, or your friend just confessed your ex is going to be at that party next weekend. Whatever the reason, it’s not wrong to want to lose weight fast. But you do want to do it in a way that’s healthy, and that won’t guarantee the pounds come right back as soon as you resume your usual diet and exercise habits. That’s why two experts weighed in on the fastest way to lose weight, no sketchy shortcuts required. (PS: This Is the Fad Diet and Weight Loss Advice That Simply Doesn’t Work.)
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.
"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
The formula for losing weight is simple: Eat fewer calories than you burn. But the methods of doing this can vary. In truth, there is no one "best" way to lose weight — what works for you might not work for someone else. To get the lowdown on the latest science on weight loss, Live Science conducted a months-long search for the best information. We contacted nearly a dozen experts who have researched weight loss, and looked at the most well-regarded studies of weight loss done to date.

There are different types of HIIT but an easy one to begin with is to simply warm up for 3 minutes on an elliptical machine or by walking.  Then work out for 30 seconds so that at the end of the exercise you feel satisfied.  Reduce the speed to slow down to a moderate pace.  Do this 7 more times or for total 8 intervals. Start with one interval and as your body is ready to take more increase the intervals.  Studies show that HIIT to be the absolute premier cardio for weight loss and optimal health as compared to longer, traditional cardio.
If you're achieving a calorie deficit, your body will tap into its own energy stores (aka, fat) and use that instead. "For many people, but not all, losing weight requires eating less," Caroline Cederquist, M.D., founder of diet delivery program bistroMD, tells SELF. Exercise is important, too, but there's truth to the adage, "You can't outrun a bad diet." It's generally easier to lower calorie intake than it is to burn enough calories through exercise to compensate. On the flipside, it's very easy to overeat highly caloric foods in two seconds flat, but burning calories through physical activity takes time (and a whole lot of energy).
