Weight loss, to feel healthier, to prepare for a specific event, or just as a boost in the fitness journey, is on most people's bucket list. Rapid weight loss does need to be approached with care because of potential health risks. In that case, five of the well-researched diets from U.S. News & World Report on Best Diets can be of help in losing pounds efficiently in 2025.
Even when aiming for rapid results, balance and nutrition are key. Structure your meals as follows:
Rapid weight loss may be beneficial to people who face health issues, such as diabetes, high blood pressure, or high cholesterol. In this regard, when their BMI is greater than 30, the very low-calorie diet may be recommended by physicians. These VLCDs may help in controlling risks and facilitating a healthier weight, which further minimizes the chances of suffering from severe conditions, including postmenopausal breast cancer and colon cancer.
For others, rapid weight loss may serve as a motivational impetus but should be balanced with efficacy and sustainability. A healthcare provider should be consulted before beginning any weight loss program.
The Jenny Craig Diet is a highly structured meal program that provides clients with prepackaged, portion-controlled foods to manage calorie intake while teaching them healthy eating habits. This also includes the practice of intermittent fasting for better effects.
One thing that differentiates Jenny Craig is one-on-one coaching. Members receive individualized advice on the timing of meals, portion control, and balanced eating, leading to sustainable weight loss. The average weight loss for participants is 1–2 pounds per week, which makes it a very practical approach for people seeking steady, fast results.
The ketogenic diet, or keto, emphasizes high-fat and low-carb foods to induce ketosis, a state where the body burns fat for energy. This approach leads to significant weight loss, especially in the initial stages.
Beyond weight loss, keto is also said to improve mental acuity, energy, and stabilization of blood sugar. However, the diet's strictness comes at a great cost. Fattening avocado, fatty fish, nuts, and lean proteins are the stars, while carbohydrates in the form of bread, pasta, and sugar are banished.
For individuals who want a convenient, time-saving diet, SlimFast offers effective meal replacement solutions in the form of shakes, bars, and smoothies. It is great for losing up to 20 pounds, meaning participants can get to their goals in 8–10 weeks.
While convenient, it's important to balance other meals with nutrient-rich foods in order to avoid deficiencies. SlimFast is ideal for a busy person who cannot find time for meal planning but wants to lose weight rapidly.
WeightWatchers, recently branded as WW, combines the strengths of behavioral science, nutrition, and technology into a total solution for weight loss. In their point system, users get the freedom to choose from hundreds of foods.
WW is more than a weight loss program, offering programs designed for people with diabetes or those on GLP-1 drugs like Ozempic. The program is comprehensive with a strong app, recipes, and support groups, making it accessible and effective.
The Volumetrics Diet flips the conventional diet on its head, focusing on low-calorie-density foods that are high in nutrients. Think fruits, vegetables, broth-based soups, and whole grains. Participants eat filling, water-rich foods, so they consume fewer calories while still feeling satisfied.
Volumetrics isn't a restriction diet but rather a lifestyle, teaching one portion control and how to eat. It's not a diet, as most of the ingredients can be sourced at any local grocery store.

Though effective diets, rapid weight loss comes with its challenges:
Many rapid plans will initially cause water loss, which is sure to return after the normal eating habit is resumed.
Fad diets will always create an urge to consume and hinder one's ability to stick to a diet for long periods of time.
Eliminating specific food groups entirely can lead to the omission of necessary vitamins and minerals.
These three challenges can be overcome by focusing on rapid weight loss as the stepping stone to good lifestyle changes. This should be complemented with exercise, mindful eating, and stress management to sustain progress.
Quick diets may be a great starting point, but sustainable lifestyle habits are essential for long-term success. These include regular exercise, balanced nutrition, and control of stressors. All of these can maintain a healthy weight.
In any case, all these diets focus on achieving one goal- that of general wellness. Begin small, and create a base upon which to sustain long-term outcomes.

Global hunger declined for the third consecutive year in 2025, but an estimated 645 million people still went hungry, while rising food prices linked to the Middle East conflict threaten to slow progress, according to a new UN report.
An estimated 7.8 percent of the global population—around 645 million people—were affected by hunger in 2025, down from 8.1 percent in 2024 and 8.6 percent in 2022, according to The State of Food Security and Nutrition in the World 2026 (SOFI 2026) report released on Tuesday by five UN agencies—FAO, IFAD, UNICEF, WFP and WHO.
The figure represents 14 million fewer hungry people than in 2024 and 43 million fewer than in 2022, marking the third consecutive year of improvement.
"While we welcome the clear progress we have made in reducing hunger, a healthy diet still remains unaffordable for one in three people globally. Obesity is rising and progress on maternal and child nutrition is stalling," said WHO Director-General Dr Tedros Adhanom Ghebreyesus.

Despite the decline in hunger, 25.8 percent of the world's population—around 2.1 billion people—experienced moderate or severe food insecurity in 2025, meaning they were forced at times to compromise on the quality or quantity of the food they consumed.
This is down from 27.1 percent in 2024 and 28.7 percent in 2020, equivalent to 86 million fewer people than in 2024 and 135 million fewer than in 2020, although levels remain above those seen before the COVID-19 pandemic.
Africa is now home to the largest number of hungry people, with 309 million affected.
More than half (56.6 percent) of Africa's population experienced moderate or severe food insecurity in 2025, compared with:
Women continue to be disproportionately affected by food insecurity, although the gender gap narrowed slightly in 2025.
The report warned that the ongoing Middle East conflict could delay global efforts to end hunger by driving up food prices through higher energy and fertilizer costs.
Depending on how long the crisis affects food inflation, 510–520 million people could still face hunger by 2030, compared with 503 million projected before the conflict, the report said.
It also noted that other risks—including extreme weather events such as El Niño in 2026 and 2027—were not included in these projections and could further worsen the outlook.
The report warned that the conflict, combined with extreme weather and declining humanitarian funding, threatens to reverse recent gains in reducing global hunger.
"This report is a stark reminder that food systems fail millions of children and families. Food, health, education and social protection must go hand in hand to protect the most vulnerable children and women from global shocks," said UNICEF Executive Director Catherine Russell.
Nutritious food has become up to 25 percent more expensive over the past five years, leaving 2.69 billion people—nearly one in three globally—unable to afford a healthy diet.
The average global cost of a healthy diet rose to US$4.28 (PPP) per person per day in 2025, up from US$3.44 in 2021 and US$2.94 in 2017.
Dr Ghebreyesus urged governments to adopt policies that make "healthy food the easy choice," including promoting breastfeeding, front-of-pack nutrition labelling, taxing unhealthy products, and protecting children from harmful food marketing.
"Healthy diets are not a luxury—they are the foundation of health and must be within everyone's reach," he said.

Love your daily cup of coffee? The way you brew it could make a difference—not just for its taste, but also for your cholesterol levels.
A new scientific statement from the American Heart Association (AHA), published in the peer-reviewed journal Circulation, stated that for most healthy adults, drinking up to five cups of black caffeinated coffee a day (up to 400 mg of caffeine) is safe and may even benefit heart health.
However, the statement, based on a review of the latest evidence on caffeine and cardiovascular health, noted that the brewing method matters because some types of coffee contain compounds that can raise LDL, or "bad," cholesterol.

According to the AHA, moderate consumption of black, caffeinated coffee without added sugar, cream, or flavored syrups has been linked to several cardiovascular benefits.
A review of the latest evidence found that drinking three to five 8-ounce cups of regular black coffee daily was associated with a lower risk of:
"Caffeine consumed in coffee is a key part of daily life for millions of people, and in our review of the most recent research, for most adults, intake of up to 400 mg of caffeine/day, the equivalent of up to five cups of caffeinated coffee per day without added sugars or fillers, is safe and does not increase cardiovascular risk," said Gregory M. Marcus, chair of the scientific statement writing group and professor of medicine at the University of California, San Francisco.
While coffee itself may support heart health, the AHA highlighted one naturally occurring compound—cafestol—that can raise LDL ("bad") cholesterol.
Cafestol is found in both caffeinated and decaffeinated coffee, but its levels depend on how the coffee is prepared.
Cafestol, associated with increased LDL cholesterol levels, is high in unfiltered coffee, including:
In contrast, paper-filtered coffee and instant coffee contain little to no cafestol, making them a better choice for people concerned about cholesterol.

The statement also found that coffee's effect on blood pressure is complex, and they called for more studies to better understand this relationship.
Yet the findings revealed that among people with normal blood pressure, drinking one to three cups a day was associated with a higher risk of developing hypertension, while consuming more than three cups daily was linked to a lower risk.
Although caffeine may temporarily reduce insulin sensitivity, regular consumption of black caffeinated coffee has been linked to a lower risk of Type 2 diabetes. Researchers believe this benefit is likely due to compounds in coffee other than caffeine.
The AHA cautioned that the findings do not apply to energy drinks or energy shots. These products contain much higher concentrations of caffeine—around 40–69 mg per fluid ounce, roughly three to four times more than regular brewed coffee—and have been linked to high blood pressure, abnormal heart rhythms, and other cardiovascular risks, even in healthy adults under 30.
Marcus stressed that there is no one-size-fits-all recommendation for caffeine intake because people respond differently based on age, genetics, medications, underlying health conditions, and how quickly they metabolize caffeine.
He advised people to pay attention to how their body responds to caffeine and discuss their intake with their healthcare provider if they experience symptoms such as palpitations, anxiety, or sleep disturbances.

Nutritious food has become up to 25% more expensive over the past five years, leaving nearly one-third of the global population unable to afford a healthy diet, according to a new report released by the United Nations.
The 2026 State of Food Security and Nutrition in the World, published by the UN Food and Agriculture Organization (FAO), estimates that a healthy diet now costs an average of US$4.28 (S$5.52) in purchasing power parity (PPP) dollars per person per day.
"A healthy diet costs 25% more than it did five years ago. One-third of the global population can't afford it. The cost of a healthy diet shows where agrifood systems investments can have the greatest impact," Máximo Torero Cullen, the FAO's Chief Economist, wrote in a post on social media platform X.

The full report, to be presented on July 21 at the organization's headquarters in Rome, found that the cost of a healthy diet is unevenly distributed across different food groups.
"The challenge is not to produce enough calories; it is to make nutrient-rich foods more affordable," Torero said during a press conference, as quoted by AFP. The full report will be presented July 21 at the organization's headquarters in Rome.
He emphasized that strengthening local food production could significantly lower the cost of healthy diets.
Torero also highlighted two major uncertainties that could further drive up global food prices:

While eating a healthy diet is widely recommended to reduce the risk of chronic diseases, experts say there is no one-size-fits-all approach. Nutritional needs vary based on factors such as age, health status, activity level, and cultural preferences.
According to Harvard Health, the key principles of a healthy diet include:
