So, a potentially sensitive subject.
However, it's true that body fat (how much and where) is a big contributing factor to how masculine you appear at a first glance. Body fat also obscures muscle definition, which is the opposite of what a lot of us want!
My experience here has been entirely with LCHF eating - low carb, high fat, that is - a variation on the 'primal' style of dieting - and I've got nothing but good things to say about it. Mostly, I've followed the guides put together by J. Stanton of
Gnolls.org, but the jist is this: no sugar, no grains, no plant oils (coconut oil is OK), lots of veggies, some fruits and nuts, and lots of grass-fed/pastured animal products including butter, eggs, cream, offal, and everything else. I'm vegetarian, so I just eat a lot of butter, eggs, pastured cheese and organic tofu.
I initially switched to this style of eating for reasons of metabolic inflexibility and my tendency to get hypoglycemic... pretty much every day. Ten years down the road, I could have easily set myself up for insulin resistance and pre-diabetes. No bueno. So, while I didn't actually cut the carbs to lose weight, I lost weight anyways: 10 pounds in two weeks, even. My BMI went from 20.5 to 19, and I didn't even notice until I stood on a scale. Aside from a single day battling the low-carb 'flu', I never felt hungry, listless, foggy, or any of it. In fact, my energy is better than ever.
So, that was my unintentional strategy.
The result? Less fat around my hips and thighs, and a pretty ideal blank canvas for me to start throwing some muscle onto. As far as that goes, I bought myself a pull-up bar and set of resistance bands. Planks, pushups, wall-sits... I'm gunning for abs, good thighs, and damn good arms/shoulders. Still learning about all the tricks out there to maximize gains, but lean and strong is at least better than skinny in the meantime.
Any one else got some pointers to share?
