You can loose weight without going on a low carb diet though plus like is said 100g is not a lot with your fruits and vegetables also giving you carbs. Like sara516 said you will loose water weight that’s going to come right back.
What happens when you are on a low carb diet is that you burn off all the carb stores then some fat but ALSO muscle mass.
I just remembered for those of us who are not athletes and highly trained it is best to exercise at a moderate pace and not very intense since you will burn of more fat at moderate than at high intensity. There are a few reasons for that which i don’t want to get into.
So I suggest you eat healthy small portions and snack with helathy foods such as yogurt, fruit, nuts etc. Overall eat more proteins (desi diets are low) adequate/moderate crabs (desi diets are very high) and low in fat. Along with moderate intensity exercise.
