I’m just in my 5th week (starting today) and have lost 11lbs, with another 9 to go, and I understand your frustration that things don’t happen quicker.
This really isn’t a diet as such as another way of eating/looking at food and appreciating that the refined carbs we eat and the low fat stuff we’ve been recommended is actually making us fat
Everyone’s body responds differently
I had a plateau and didn’t lose weight for a while but could see my waist reducing and that I looked thinner. How could that be? I have been keeping (good) carbs down and testing myself with Ketostix which show that I am burning fat and so it must have been going from my internal organs which is great.
I have also been told that visceral fat goes first and only then the subcutaneous fat (the bit you can see) and the last bit is the belly fat – it would be!
I suggest you try logging on to MyFitnessPal and check what you are eating. Cutting back carbs to 50g per day and making sure you are having enough fat (cheese, full fat dairy etc) which will fill you up.
This worked for me. Why not commit to the full 8 weeks and see what transpires – if you give up now you will never know.
Don’t give up! Loads of people here have had plateaux and worked through them. And it really is a different and healthier way of life, not just a diet
Good luck!
