Hi
BackOfficeProI can understand your concern. Basically, you are bothered by the fact that without increasing your dietary intake, you have put on weight.
Few things to consider before zeroing in on your problem!
1. Is the new work environment stressful? Increase in mental stress can increase your sympathetic activity which can lead to high stress hormones, result: water retention and fat conservation. A good way to avoid stress can be to workout (Strength Training) or go for a cardiovascular exercise (Cycling, running) for atleast an hour a day to get your mind off.
2. If your work environment is not stressful, have you altered the type of calories you consume? for example new workplace can have meals which are calorie dense. So you might think you are consuming same amount of calories, but instead you are consuming much more. Do a dietary audit!!!
3.
Fluids. Many a times we substitute water with carbonated drinks, sugerfree or not, these drinks dehydrate us further and cause us to consume more and more. The net effect is high calorie intake through fluids.
4. To lose weight (Without any harmful effects) try to increase protein intake . The leaner the protien, the better. Prefer Chicken, Eggs over red meat. Decrease the portion size and increase the meal frequency.
Hope this will help. If you have anymore issues, I would be more than happy to help a colleague out!!
Cheers.
