OK...I know it's not as simple as this, but does anyone have any insight on how either of these two variables might be playing a role in what feels like a recent fat gain around the mid-section. They are the only two things I can identify that have changed since I started feeling bloated. Diet's the same, sleep's the same, all other activity the same, stress is low.
I've gained fat around my belly over the past 2 months and...
Fish oil - I have an inflammatory disease and was taking anywhere between 6 and 10 grams depending on inflammatory state. I stopped all fish oil about 2 months ago.
Kettlebells - I started a kettlebell routine for the first time about two months ago. Three sets each of swings, cleans, clean/shoulder press, and get-ups on a 32kg bell.
Once you stopped the fish oil, did you make sure to get enough omega 3 via diet? Also, the omega ratio is as important as the overall amount, so it could be that your fish oil megadose was balancing out your omega 6 intake and putting you within the right range of ratios.
What does your diet look like? Also, how's your sleep/stress? This sounds like it might be a cortisol issue.
Is it jiggly or solid? My hubby and I have been joking about developing upper belly "outy abs" that seems to be related to picking up and putting down a wiggly 35 lb. bundle of energy a million times per day. So maybe a kettle-ball could do a similar thing. We've been trying to figure out what what we're doing form-wise that could cause this, and I do find myself pushing my belly outward when I lift sometimes. What is your belly doing when you lift that kettle-ball?
