Green juice
 Green juice can be quite tasty, and if you heed a few parameters,
 you may experience health benefits such as more energy, improved immunity and weight loss.
The key is making sure you control the calories -- in addition to consuming your juice at the right time.

Lemons
According to the Journal of the American College of Nutrition, vitamin C
levels are inversely related to body mass. People with adequate levels of vitamin C
oxidize 30 percent more fat during moderate exercise than those with low levels of vitamin C.
 Start your day with a glass of lemon water and substitute fresh lemon juice for vinegar on your salads.

Grapefruit
Grapefruit is low in calories, high in enzymes and can keep you full. In a study published in the Journal of
 Medicinal Food, researchers found that eating half of a fresh grapefruit before meals was associated with significant
 weight loss among obese study participants. Researchers also noted that participants who consumed grapefruit before
 a meal also experienced a significant reduction in two-hour post-glucose insulin levels.

Apple cider vinegar
Produced by fermenting apple cider, apple cider vinegar is known to be a rich source of minerals, enzymes,
vitamins and amino acids. A study cited by the American Diabetes Foundation found that consuming apple-cider vinegar
before a high-carb meal significantly increased insulin sensitivity, reducing insulin spikes that can lead to cravings.

Carrots

Health Benefits
One of carrots' fat-fighting features is their respectable fiber content,
half of which is the soluble fiber calcium pectate. Soluble fiber may help
 lower blood-cholesterol levels by binding with and eliminating bile acids,
 triggering cholesterol to be drawn out of the bloodstream to make more bile acids.

Coconut oil
Coconut oil has been making headlines as a new superfood – and some believe it can help you lose weight, too.
Coconut oil is made up of medium-chain fatty acids, which are metabolized differently than the long-chain fatty acids found in most fats.
These medium chain fatty acids are used first and foremost for energy in the body, instead of being stored as fat.

Easy ways to cut calories and lose weight fast.
To lose weight, you need to cut calories. To lose weight fast, you need to cut more calories. For every 3,500 calories you cut, you lose 1 pound. (So minus 500 calories a day equals a loss of one pound a week).
Generally, not lower than 1,200 calories per day, say weight-loss experts.
