Before covering how to lose belly fat in 1 week, let’s first get my baseline measurements. My initial DEXA scan came in at 15.6% body fat. I also used the ultrasound to measure the exact thickness of my upper belly fat, middle belly fat, and the most stubborn area, my lower belly fat. After seven days, we’ll come back and see just how much these measurements have changed.

With this diet, I’m eating just 1,200 calories. It’s extreme, but sticking to it should lead to about 3 lbs of pure fat loss in just a week.

Alberto Nunez, “the go-to man” to get you absolutely shredded in the natural bodybuilding community, terms it the protein-sparing modified diet. He shares that, on this diet, you’re eating nothing much other than protein. And given how extreme this weight loss diet is, Alberto recommends 1.5 to 1.75 g of protein per lb of body weight. For me, that translated to a bare minimum of 250 grams of protein on a budget of just 1200 calories per day. As for protein sources? It’s going to be a lot of the leaner animal proteins.

Here’s my daily meal plan to lose belly fat fast. Egg white omelet with celery for breakfast, a post workout Built With Science protein shake, two chicken breasts with light veggies for lunch, more chicken and veg for dinner, and more chicken breasts for desserts.

So, when it comes to weight training, research has shown that it only takes about 1/3rd of the volume to MAINTAIN your existing muscle. This means, rather than doing 3 sets per exercise, I could do just 1 hard set and that should be enough to protect my muscles from being burned off without being too much for my body to recover from. Now, even though I’m not getting all the nutrition I need because of my strict calorie limit, I’m trying to use a few key supplements to fill in the gaps, including a multivitamin, Omega 3s, and some clutch recommendations I got from Alberto: caffeine and protein powder.

3 days in, and I felt great. But Alberto cautioned that my body was probably going to start bugging me soon. True enough, I felt a rapid energy drop going into the second half of the week. As for my food cravings, the longer I went into the diet, the crazier those cravings became.

So when your body experiences a serious drop in calories, it starts to do whatever it can to tell you to eat. Not only can your smell and tase become heightened, but your leptin levels can decrease dramatically. Meaning, not only was my stomach physically feeling empty but even the signals in my body meant to regulate my hunger were starting to go haywire.

Feeling absolutely depleted, I headed back to the lab to get my day 7 results. But before I find out, I already know this isn’t a plan I will be repeating. Trying something so extreme had me feeling exhausted, unmotivated and like I was completely depleted. And when I did get to actually enjoy real food again I actually had to spend the next few days resisting the urge to eat everything in sight.

Diets like this are exactly what cause so many people to yoyo diet and even develop eating disorders. To truly lose belly fat and keep it off, you need patience, consistency, and a sustainable diet that you can stick to for several weeks.

Regardless of what the results show in the scans, do not try to copy what I did in this video. As for my results, my DEXA scan showed that my body fat dropped from 15.6% to 14.7%. It doesn’t sound like much but usually it would take me at least a few weeks of dieting to achieve that.

But what’s interesting is the ultrasound.

Although my upper and middle belly fat didn’t change much since I didn’t have too much to lose there, my lower belly fat, which is the most stubborn area, dropped by over 30%! In fact, the thickness of my lower belly fat dropped by half a cm! Which explains why I noticed my lower abs starting to pop out a little more.

But despite the results, I wanted to get even leaner, so I decided to continue dieting for the next 6 weeks. This time, using a more sustainable approach. My plan is to head back to the lab for 1 more scan to see just how much more belly fat I was able to lose, and then make a video for you guys revealing everything I did to easily lose that fat. So keep an eye out.

  1. what do you mean it's not a pleasant diet? A whole chicken + eggs. For a sec I thought it would be costly as well, but then I realised a whole chicken costs ~5GBP so if I eat nothing but that, it's actually MUCH cheaper than usual groceries 🙂 And for training, instead of a bunch of targetted, isolated exercises, just go for a kettlebell circuit. Ok… Challenge accepted… Once I exhaust all the vegies in my fridge, I'm going for it.
