What is a good diet plan to lose weight?

For Breakfast - A Drink of Warm Water And Lemon Juice

For Lunch - Have A Grapefruit And Slice Of Bread (NO BUTTER AND ONLY ONE SLICE)

For Dinner - Have Salmon Or A Breast Of Chicken (No Red Meat) And Some Green Vegetables.

You Will Find You Have Less Energy Then Usual But If Your Willing Enough, You'll Ignore The Side Effects.

P.S

I used this diet and lost over a stone
