dieting by whole grain

I’ve been successfully dieting for the last 6 months but I’ve hit a plateau.
I found a whole grain cereal that promises that after substituting 2 bowls for 2 meals
I’ll lose 10 lbs after 2 weeks.
my questions are what would happen if I made all my meals cereal? is it healthy? Will I continue to lose weight? I mean,cows eat grain and they ain’t skinny.

Humans aren’t cows and it ain’t healthy. I’m sure someone else will come in and set you straight, but Scurvy much? The replacing meals with cereal thing only works by reducing calories, and I imagine it is supposed to be more of a short-term kickstart to a diet.

Quite simply you can not survive on a grain diet. You would lose weight, and then you would lose hair, then you would lose skin tone, then you would lose heartbeat.
There are a lot of things your body needs that aren’t found in grains, or aren’t found in sufficient quantities. Even with a carefully formulated blend of grains you will be hard pressed to get all the amino acids your body needs, you will also tend to be seriously short of essential fats and several major vitamins and minerals.

You shouldn’t embark on any radical dietary program without seeing your doctor, and that applies to a diet where you only eat one real meal a day. You can theoretically manage such a thing without trouble if that third meal is well-balanced and carefully formulated and if you have no pre-existing conditions. But you can’t just scrap one meal a day and continue on as normal.

As for justs subsisting on a whole grain diet, it’s impossible in the long term and damging in the short.

you would need to take lysine supplements to cover the amino acid gap.

If you ate total you wouldn’t get scurvy. There is an article here somewhere about how long a person could survive solely on bread. The answer was about 2 years.

I doubt she is serious about staying on a grain diet for any prolonged period of time.

Actually, this is a currently-running promotional campaign for some of the marketed-as-healthy General Mills cereals. Something about replacing two meals a day with the cereals (Total, et.al.) and losing 10 pounds. Which is fine, but what’re you going to do afterward?
