Hi Tina
There really is no one-size-fits-all plan for losing weight. You have to find the method that works for you. Personally, I count calories and log my food using myfitnesspal, and follow no specific food plan (restricting, for me, leads to binging). Others do low carb, others do intermittent fasting.
Best way to go about it is don't look at as a quick fix. Find your method and stick with it long term. (And don't give up on it, like I did, and find yourself right back where you started!)
