Will eating one fatty meal make me put on weight
if i keep eating healthy after?
No... as long as you dont make a habit of it. It is ok to "cheat" on a diet from time to time. Just dont stay idle.
One fatty meal can be an exception on an occasion. But everyday one fatty meal will bring a change in two weeks.
If you are eating one fatty meal, it will make some difference on weight. It will definitely cause some weight gain in your body because of the calories consumed in the body from the fatty meal.
not if you are active
No it's just calories but you should always burn them off by excercising
Not if it's only once a day
