The good: If you take away (or restrict) a whole food group then you’re, in theory at least eating less calories. This leaves the majority of your choices to be protein and fats. These are satiating nutrients which means they keep you feeling full for longer…good news when you’re dieting. It’s also report to help keep your blood sugar more stable. It seems to work quicker, the scales starts dipping a little quicker than more traditional approaches due to the fact that you shed a little more water and glycogen with this approach. To note though over time, that effect balances out.
The cons: As with any restrictive plan, you’re potentially leaving behind some healthful benefits of those foods that are left out. Add to the fact that some people just don’t do well on this approach with some reporting a change in, ahem, toilet behaviour due to a lack of fibre and it simply mightn’t suit everyone.
The stupid: Believing that carbohydrates, and/or sugar are the only reason for weight gain and/or certain medical conditions tops the charts on this one.
