In view of the faddy diet threads springing up on Gransnet...

I agree absent and unfortunately weight loss will only be maintained if there is a permanent change in eating habits.
jingl just because something is promoted by the NHS doesn't mean it's right or evidence-based. The NHS Eatwell Plate recommends that nearly half people's food intake should consist of carbohydrate - mainly starchy foods like bread, pasta, potatoes and rice, and includes some sweet things too.
The problem is satiety - how full you feel.
Anyone trying to restrict calorie intake and adhering to the recommended levels of carbohydrate on the Eatwell plate would find themselves hungry most of the time and restricting calories very difficult indeed.

You are, of course, right jingl but lots of people (not specifically gransnetters) want virtually instant results. Unfortunately, losing excess weight and not regaining it, like almost anything worthwhile, takes time.
