This popular diet program is fairly restrictive — and for the first 30 days, dieters must cut out grains, legumes, most dairy, added sugar, and alcohol without any slip-ups, according to the Whole30 website. (29) The aim is to “reset” your body and to adopt dietary habits resulting in weight loss. Cutting out added sugar and alcohol has merit, but all the restrictions prove challenging and could lead to nutrient deficiencies and disordered eating.

Fiber works its weight loss magic in multiple ways. It helps you feel fuller, longer so eating fiber-rich foods is the dieting equivalent of working smarter, not harder. Plus, fiber takes a long time to digest, so fiber-rich foods don’t cause spikes in blood sugar that can send your insulin levels soaring. On the other hand, when you eat the so-called bad carbs (the refined or sugary ones that lack fiber), you may wind up with an insulin response that promotes fat storage. The takeaway: More fiber equals less fat storage.
It’s called a “beer belly” for a reason. Boozy bubbles are a major cause of belly bloat, as anyone who’s ever looked in the mirror after a few too many drinks can attest. But it’s not just the carbonation that is the culprit. Alcohol can lead to an overgrowth of bad bacteria in your stomach, leading to gas, not to mention all the empty calories that are going straight to your waistline. Instead, skip the alcohol altogether or limit yourself to one serving per day.
