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:

• Fill half your plate with non-starchy options like spinach, zucchini, and bell peppers.
• Include lean sources such as chicken, tofu, or eggs to preserve muscle mass.
• Add avocado, nuts, or olive oil for essential nutrients.
• Choose complex carbs like quinoa or sweet potatoes, but keep portions small.

Is Rapid Weight Loss Ever a Good Idea?

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.

5 Best Diets for Rapid Weight Loss in 2025

1. Jenny Craig Diet

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.

2. Ketogenic Diet

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.

3. SlimFast Diet

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.

4. WeightWatchers Diet

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.

5. Volumetrics Diet

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.

Essentials of Rapid Weight Loss

Though effective diets, rapid weight loss comes with its challenges:

Water Weight vs. Fat Loss

Many rapid plans will initially cause water loss, which is sure to return after the normal eating habit is resumed.

Sustainability

Fad diets will always create an urge to consume and hinder one's ability to stick to a diet for long periods of time.

Nutrient Deficiencies

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.

Lifestyle Changes for Maintaining Weight Loss

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.

A trendy drink that’s become a social media favorite may now have fans thinking twice, after questions were raised about one key ingredient.

Bubble tea, also called boba or pearl milk tea, first appeared in Taiwan in the 1980s. It’s usually made with tea, milk or creamer, a sweetener, and, of course, the signature chewy tapioca pearls.

While its colorful, Instagram-worthy appeal has made it popular around the world, recent safety tests from Consumer Reports suggest there could be reason for concern.

Boba Tea Contains Lead?

Bubble tea, the Taiwanese drink made of black tea, milk, sugar, and chewy tapioca pearls, has won fans worldwide since its debut in the 1980s. But recent findings suggest it may deserve a closer look.

A Consumer Reports investigation in the US found high lead levels in some bubble tea products, echoing earlier concerns about cassava-based foods. The tapioca pearls, the drink’s signature “bubbles,” are made from cassava starch, which can absorb lead and other heavy metals from the soil as the plant grows.

Why Are Tapioca Pearls Harmful?

Lead is naturally present in the Earth’s crust, and much of the world’s soil contains significant contamination. Many fruits and vegetables, including cassava, can absorb heavy metals during growth.

Consumer Reports tested tapioca pearls from popular bubble tea chains, Gong Cha and Kung Fu Tea, as well as packaged boba products from Trader Joe’s and WuFuYuan. Every sample contained some lead. Thankfully, none exceeded the levels that Consumer Reports considers concerning, and none had dangerous levels of arsenic, cadmium, or mercury in a single serving.

“These levels weren’t high enough for us to advise people to completely avoid bubble tea,” said James E. Rogers, PhD, director of food safety research and testing at Consumer Reports.

“However, this wasn’t a comprehensive survey of the boba and bubble tea market. The fact that three out of four samples contained more than half of our level of concern for lead in a single serving is a strong reminder that bubble tea should be enjoyed occasionally, rather than as an everyday drink.”

Beyond heavy metals, the starchy composition of tapioca pearls can pose other risks. Eating large amounts may slow stomach emptying, a condition called gastroparesis, or even cause blockages. Symptoms can include nausea, vomiting, and abdominal pain, and people with already slow digestion may be particularly affected.

Bubble Tea and Kidney Health

Bubble tea can also impact kidney health. In 2023, Taiwanese doctors removed more than 300 kidney stones from a 20-year-old woman who reportedly drank bubble tea in place of water. Ingredients such as oxalate and high phosphate levels can contribute to stone formation, though this extreme case likely reflects unusually high consumption.

Jason Tsou, General Manager at WuFuYuan’s parent company, Shanghai ZhouShi Foodstuffs, said the company routinely tests its products for lead through an accredited laboratory. Following these recent findings, they have introduced stricter standards to ensure safety, as per New York Post.

If you often struggle with stress or restless nights, a warm cup of tea is likely your go-to for calming down. Tea’s comforting reputation isn’t just tradition, studies suggest it can support heart health, aid digestion, and more. One key component behind these benefits is L-theanine, an amino acid found in tea leaves. Available as a supplement, L-theanine is thought to help reduce anxiety, improve sleep, and even enhance focus.

It is gaining popularity as a supplement for enhancing focus and relaxation. But does it live up to the hype? Here's what recent research reveals about its effects on attention, reaction time, and cognitive performance.

What Is L-Theanine?

L-theanine is an amino acid naturally found in tea leaves, especially in green tea and loose-leaf varieties, and is believed to offer several health benefits. But first, it helps to understand what amino acids are and why they matter.

Amino acids are the building blocks of proteins and, ultimately, life itself, as per Healthline. They are molecules used by all living organisms to make proteins. Humans need 20 different amino acids to function properly, 11 of which are essential and must come from food.

Although L-theanine is not essential for survival, research has explored its effects on brain function and cognitive performance.

You can consume L-theanine by drinking teas such as green tea, white tea, or matcha, or by taking it in supplement form, including tablets and capsules.

Can L-Theanine Really Make You Focus Better?

Yes, several studies suggest that L-Theanine can enhance focus and attention. For instance, a 2011 study published in ScienceDirect found that L-Theanine improved attention performance and reaction time in individuals prone to high anxiety.

Additionally, a 2021 study in PubMed Central reported that a single dose of L-Theanine reduced reaction time to attention tasks and increased the number of correct answers in working memory tasks among middle-aged adults.

L-Theanine appears to have a positive impact on reaction time. A 2025 study published in PubMed found that a 200 mg dose of L-Theanine reduced hit reaction time by 38.65 milliseconds in sleep-deprived individuals during a traffic-related visual recognition task.

L-Theanine Effect with Caffeine

When combined with caffeine, L-Theanine may offer enhanced cognitive benefits. A 2010 study in PubMed indicated that the combination of 97 mg of L-Theanine and 40 mg of caffeine improved accuracy during task switching and reduced self-reported tiredness in young adults.

L-Theanine: Is It Safe to Use?

L-Theanine is generally considered safe when consumed in moderate amounts, such as those found in tea or supplements. However, as with any supplement, it's advisable to consult with a healthcare provider before starting, especially if you have underlying health conditions or are taking other medications.

L-Theanine shows promise as a natural supplement to enhance focus and reaction time, particularly when combined with caffeine. While more research is needed to fully understand its long-term effects, current studies suggest it can be a useful tool for those seeking improved cognitive performance without the jitteriness associated with other stimulants.

We have been often told that milk, and dairy products are great for our bone health, especially due to its high vitamin D and calcium components. This is also true for yogurt, but is there enough evidence to support this argument? A new study published in the journal Frontiers in Nutrition checks exactly take. It has taken a closer look at the question of eating yogurt to improve bone health. While the findings may show promise, the researchers say that evidence is not strong enough to call yogurt a bone-strengthening food on its own.

Why yogurt Is Believed To Be Bone Healthy?

yogurt is made through fermentation of milk, and it uses two specific bacterial strains, namely: Lactobacillus delbrueckii bulgaricus and Streptococcus thermophilus.

While yogurt and milk share similar nutrient profiles, yogurt offers additional benefits due to the above mentioned bacteria. They also produce vitamins and biologically active compound that could support overall health.

When we age, our bones lose mass and bone formation slows down, while resorption or bone breakdown speeds up. This also increases risk of fragility fractures. This is why nutrients like calcium, vitamin D, phosphorus, and potassium play vital role in maintaining strong bones. yogurt is also rich in protein, calcium, zinc, selenium, and vitamin B and K which is also recommended as bone-friendly food.

Some experts also believe that yogurt offers an edge over milk due to the higher levels of certain vitamins and minerals it provides. Furthermore, they claim that there is a better absorption of nutrients through yogurt. However, despite this theory, the studies have only shown mixed results.

How Was the Study On yogurt's Impact On Bone Health Conducted?

For the latest study, the researcher reviewed the existing evidence on yogurt's impact on bone health. The study analyzed data from scientific databases, including PubMed, Cochrane Library, and Scopus. These were published between 1970 to 2023.

The team had both the groups, namely: healthy adults and individuals with osteoporosis. The study included a comparison of yogurt intake to no yogurt, non-fermented dairy products, or standard osteoporosis treatments. Then, they evaluated observational studies and randomized controlled trials (RCTs), extracting data on participants’ demographics, yogurt dosage, study duration, and results.

In order to ensure accuracy, the study also assessed the quality of evidence using established methods such as the Newcastle-Ottawa scale and the GRADE system. Finally, they conducted meta-analyses to evaluate two major outcomes, hip fracture risk and femoral bone mineral density (BMD).

What Did The Study On Analyzing yogurt's Impact On Bone Health Find?

The study found that of the 1,302 studies reviewed, only 12 met the eligibility criteria that represented 14 observational studies. Most of them were conducted in the US, Europe, and Asia, and focused on postmenopausal women, a group that is particularly vulnerable to bone loss.

There were some studies that found a relation between higher yogurt consumption to better bone mineral density. On fact, one of them even reported that people who consumed yogurt more frequently had a lower risk of radius osteoporosis and higher hip and femoral neck BMD levels.

However, when researchers pooled the data, the overall effect was quite small. The meta-analysis showed that yogurt intake had a statistically positive but clinically negligible impact on bone density (SMD = 0.009) and no clear association with hip fracture risk.

The team also noted several limitations. Most studies didn’t specify the type of yogurt consumed, whether it was full-fat or low-fat, fortified or plain, or contained live bacterial cultures. Since all the data came from observational studies, it was also hard to prove a cause-and-effect link between yogurt and stronger bones.
