Note: 0.05 and 0.01 are often used common levels of significance. Alpha value will be default 0.05, i.e., 5%.Variable 2 rang as after a diet column.Now select Variable 1 Range as before diet column.

Now scroll down and find T.Test: Paired Two Sample for Means.

Now go to the Data tab, and under the data, tab click on Data Analysis.
