Black tea
Like green tea, black tea contains caffeine (about 47 mg), a stimulant that is thought to increase calorie expenditure. But black tea is unique because it contains an abundance of polyphenols. These compounds have the capacity to reduce calorie intake, increase healthy bacteria in the gut, and promote fat breakdown.

Skim milk
If you’re a fan of whole milk or half and half in your daily coffee, morning cereal, or even sipping by the glass-full, swapping full-fat milk for one much lower in fat can make a difference towards your daily calorie goals. In fact, 1 c of skim milk has around 80 calories, while 1 c of whole milk has around 152. So from a calorie perspective alone, that’s nearly half the amount of calories in skim milk compared to whole milk. The fat content is another reason to opt for skim if you’re aiming for a low-fat diet, which a study showed can aid in weight loss. Skim has 0.2 g of fat per cup white whole milk has 8 g per cup.
