Despite being low in calories, soy sauce is extremely high on sodium that can leave you bloated and increase the risk of hypertension. There are many low-sodium soy sauce options available these days but they are not significantly lower than the regular ones. Use sparingly.

1. Multi-grain bread

All those pretty seeds sitting on top of the loaf look healthy and inviting. But it’s what the bread is made of that really matters. Multi-grain may not necessarily mean whole grain. Make sure to check the labels.

1. Alcohol

Even average wine drinkers consume up to 2,000 extra calories every month. A glass of sparkling white may look innocuous but its cumulative effects can hinder weight loss.

1. High-fiber snack bars

These bars contain fiber, which is essential for you, but the problem is that they deliver it in big doses, not steadily throughout the day.

Whole milk is loaded with extra fat and cholesterol. Go for the skimmed variety to enjoy the goodness of milk without worrying about the calories.
