Hello dear friend, I was overweight once and now I am just normal. I don't have an active life as I'm on the computer most of the time.
First, analyze your diet and see what goes wrong.
For me, it was excess of carbs as I was eating everything with bread. Bread with scrambled eggs, bread with sausage, bread with salad, etc. I am a person who doesn't eat seafood at ALL even if I would love to. I don't like the taste but if you do, go for it.
I don't follow a diet and all I do is simply eating carbs once a week on Sunday.
Check what you eat. Now I have a diet and eat chicken meat once a day, but every day. I buy chicken meat wholesale in Eupoultry, they have fresh meat and it is good.
