Grapefruit is a tangy, juicy fruit that is known to aid weight loss. It is rich in vitamin C and dietary fiber (7). A study confirmed that people who consumed half a grapefruit before a meal showed greater weight losscompared to those who took placebo. The fruit also reduced insulin resistance (8). Grapefruit also helps improve lipid profile, blood pressure, and reduce inflammation (9), (10), (11).
Consume half a grapefruit with breakfast and have half of it before lunch. You may also juice it (but make sure not to strain it unless you are on a low-fiber diet). If you want to try the grapefruit diet, click here.

Watermelon is a great source of vitamin C, minerals, lycopene, and water (12). A study concluded that consuming two cups of watermelon a day could increase satiety and reduce weight,BMI, and blood pressure (13). Another study stated that the lycopene in watermelon might help reduce high blood sugar (hyperglycemia) (14).

Consume at least one cup of watermelon every day. Consume it 1 hour before lunch.

Lemons are loaded with vitamin C, a potent antioxidant (15). Scientists have found that lemon peel extract reduces body weight and fat accumulation in mice by increasing fat oxidation (16). A 11-day lemon detox diet showed a greater reduction in body weight, BMI, waist-to-hip ratio,  insulin resistance, and body fat percentage in humans (17).

A short-term lemon and honey juice fast also lowered serum triglyceride levels (18). Lime (nutritionally identical to lemon) and cumin, when taken for eight weeks, showed a beneficial effect on body weight, lipid profile, and cholesterol (19).

Consume a mixture of juice of half a lime, one teaspoon of organic honey (optional), and warm water regularly in the morning.

According to the USDA, apples are rich in beta-carotene, water, fiber, vitamins, and minerals (20). Consumption of a whole apple or apple juice showed promising weight loss results (21). A study found that people who consumed apple in any form had lower BMI and were 30% less likely to be obese than those who didn’t consume apples at all (22).

The antioxidants in apples help reduce oxidative damage, thereby reducing the risk of cardiovascular diseases (23). Another study confirmed that consuming apples and pears induced a greater weight loss in overweight women than women consuming oat cookies (24).

Consume at least one whole apple a day. You can have it with breakfast or before lunch.

Blueberries are rich in anthocyanins, an antioxidant that imparts the dark blue-violet color to them (25).Researchers found blueberry anthocyanins to be the key players in reducing obesity risk, bad cholesterol, and improving insulin sensitivity in humans and lab animals (26). The dietary fiber in blueberries may also reduce hunger. Blueberry anthocyanins were also found to inhibit weight gain (27).
Consume a fistful of blueberries with breakfast in the morning. You may also make a smoothie with blueberry, oats, and almond milk.

Avocado is a delicious buttery fruit. It is a rich source of monounsaturated (MUFA) and polyunsaturated fatty acids (PUFA), dietary fiber, vitamins, and minerals (28). Research studies confirm that consuming half to one avocado a day increases satiety, reduces bad cholesterol, helps maintain weight, and improves cardiovascular health (29), (30), (28), (31).

Consume half an avocado with toast, in smoothies, with freshly made guacamole, or in salads.

Oranges and blood oranges, along with a low-calorie diet, may help reduce weight. Remember, commercially available orange juices have added sugar, which may not serve the purpose. Freshly pressed orange or blood orange juice (or the whole fruit) helps reduce body weight, body fat, insulin resistance, and LDL cholesterol (32), (33), (34).

Consume one whole fruit or juice it. You may also make a delicious salad dressing or add orange slices to a salad.

The luscious red ruby-like pomegranate contains anti-obesity nutrients. The anthocyanins, tannins, polyphenols, and flavonoids (antioxidants) in pomegranate make it a perfect fruit for reducing fat (35). A study states that the antioxidant potential of pomegranate juice is more than that of red wine or green tea (36). Another study states that pomegranate extracts may help lower blood pressure levels (37).

Consume half a cup of pomegranate every alternate day. You may add it to salads, salad dressings, and juices.
