I did it before for weight loss, it worked amazingly, but the weight came back on just as easily. It would have to be a permanent lifestyle change, and I'm not convinced that's safe.
Also would encourage you to read up on recent literature about fats. The "low fat = healthy" fad hasn't held up for some time.

> The recommendation to limit dietary saturated fatty acid (SFA) intake has persisted despite mounting evidence to the contrary. Most recent meta-analyses of randomized trials and observational studies found no beneficial effects of reducing SFA intake on cardiovascular disease (CVD) and total mortality, and instead found protective effects against stroke.
There's no magic pill, if your current lifestyle makes you fat, you need a lifestyle change.
