@ninnymary , I think losing those needed 5 pounds is harder than losing the first 20, or 30. I think a body puts the brakes on once it gets close to target weight...I don't know, maybe it's the fear of starvation that is in every body.
Conversely, if you only have 5 pounds to lose in the first place, you can lose it pretty rapidly by going strict keto, but it is going to be water emptying out of your cells. You can keep it off as long as you are strict keto, but as soon as you allow yourself a slice of bread, the process of utilizing that carbohydrate makes your body again retain water in the cells. Therefore: weight gain.
If you are borderline diabetic or already type 2, Keto certainly offers help in that situation, and you have more incentive (hopefully) to stick to it. And you lose weight in the process. Yay!
Anyone who decides to start a strict keto lifestyle needs to research it thoroughly. You can mess yourself up by eating only protein and veggies, without enough fat. And you need mineral supplements: calcium, potassium, sodium, magnesium, so you don't get leg cramps.
The Next Big Thing in the news now is that intermittent fasting is being considered for weight loss and insulin control. Fasting, once you have broken the sugar habit by using keto, is going to be easier, as you have already trained your body to use body fat rather than a constant inflow of carbohydrates for energy.
