Eating More Protein, Not Less, May Be Key For Women Struggling With Weight Loss and Muscle Gain

A growing body of research is overturning traditional advice about dieting, pointing toward higher protein intake—rather than food restriction—as a more effective strategy for healthy fat loss and muscle gain. In particular, a recent spotlight on high-protein diets for women suggests that simply eating more protein could significantly improve body composition, even without altering overall calorie intake or increasing exercise.

For many Thai women, and indeed women globally, the prevailing wisdom of “eating less” for weight loss has dominated health messaging for decades. However, this restrictive approach can lead to unhealthy cycles of under-eating, poor nutrition, and difficulty sustaining weight changes. As highlighted in a recent mindbodygreen article, nutrition experts warn that the popular advice to cut back on food overlooks a critical element: protein intake. According to exercise physiologist and nutrition scientist referenced in the article, inadequate protein may be a key reason why some people struggle to lose fat and build muscle.

New research provides compelling evidence for this shift in approach. A 2020 randomized controlled trial published in the “British Journal of Nutrition” examined the effects of a high-protein (HP) versus standard protein (SP) diet in women with normal-weight obesity syndrome—a condition sometimes called “skinny fat,” where a normal body weight masks a high body fat percentage with associated health risks source: Wikipedia. Fifty women participated, with the HP group receiving 25% of total calories from protein over 12 weeks, compared to 15% for the SP group. Both groups kept overall calorie intake the same.

The results were telling: while there was no significant change in scale weight, women who followed the high-protein diet saw substantial improvements in their body composition. There was a clear increase in lean body mass, and reductions in fat mass, body fat percentage, and waist circumference. These findings echo other clinical evidence that higher protein intake promotes not just muscle gain but also a redistribution of body fat, especially when paired with exercise and sufficient calorie intake PubMed study.

Physical activity further enhances the benefits of higher protein intake, but the core message is that even sedentary women can experience measurable body recomposition by shifting their diets towards more protein. Importantly, these results challenge the notion that successful weight management is about lowering food quantity; instead, it emphasizes food quality and macronutrient balance, particularly for women.

Expert opinions cited in the mindbodygreen article and other reputable sources underscore how current recommended dietary allowances (RDAs) for protein fall short for women—especially active individuals. The standard RDA, roughly 0.8 grams per kilogram of body weight, was originally based on data from sedentary older men and aims to simply avoid malnutrition, not optimize health or performance. For most women seeking to build muscle and decrease fat, experts suggest increasing intake to between 1.6 and 1.8 grams per kilogram, and up to 2.2–2.4 grams for those who are peri- or postmenopausal, due to hormonal shifts that change protein requirements Everyday Health report.

How does this translate for Thai women? According to the Dietary Reference Intake for Thais 2020, the general recommendation for adults is around 1 gram per kilogram of body weight, which is roughly in line with international conservative averages. However, these new findings suggest active women or those aiming to optimize their body composition should consider even higher protein targets, especially as they age or if they are physically active.

Making practical dietary changes to hit these protein goals can be daunting, especially in a food culture where traditional staples include lower-protein options like rice and noodles. Nutrition experts recommend several accessible strategies: include protein-rich foods in every meal and snack, add protein boosters such as tofu or eggs to stir-fries, swap white rice for higher-protein grains like quinoa, and incorporate beans or lentils into soups or curries. For Thai readers, these swaps might include dishes such as “moo krob” with extra eggs, “tom kha gai” with more chicken breast, or “laap tofu” as a plant-based protein option.

It is also important to balance protein intake throughout the day, aiming for about 30 grams per meal for premenopausal women, and 40 grams for those postmenopausal or in later peri-menopause. This helps support muscle protein synthesis, a process crucial for building and maintaining lean muscle mass Everyday Health.

While increasing protein alone will not guarantee dramatic weight loss—successful body composition change also depends on overall dietary patterns and regular movement—the evidence clearly points to protein as an underused but highly effective tool, particularly for women. As a fat loss coach told the Hindustan Times, “Eating more protein isn’t enough unless you are mindful about where you are getting your protein from and how it fits into your total nutrition.” Quality sources such as lean meats, fish, eggs, dairy, and a variety of plant proteins all play a role Hindustan Times.

Culturally, Thai society places a strong emphasis on fresh ingredients, home-cooked meals, and balanced eating—all strengths that can support healthy increases in daily protein intake. However, affordability and accessibility remain considerations, especially for lower-income groups or those living in rural areas where animal protein may be more expensive or less available. Selecting affordable protein-rich foods like eggs, tofu, tempeh, fish, and legumes can help bridge this gap.

Looking ahead, Thai policymakers and health educators may wish to revisit dietary guidelines for women, especially as emerging research reshapes the global conversation around optimal protein intake and its role in combating both obesity and sarcopenia (age-related muscle loss). Future studies specific to Thailand’s population, dietary habits, and health trends would support more tailored recommendations.

In conclusion, for Thai women aiming to lose fat, gain muscle, or simply feel their best, rethinking longstanding beliefs about “eating less” and instead focusing on “eating smarter” with more protein may be the key. Readers are encouraged to assess their current intake, speak to registered dietitians for personalized advice, and make gradual shifts towards protein-rich meals that fit their preferences, cultural context, and health goals. As always, sustainable health comes from balance, variety, and small, long-term changes rather than drastic diets.

Intermittent Fasting: Weighing the Latest Science on Weight Loss and Health

news nutrition

Intermittent fasting has surged in popularity as a dietary trend, championed for its potential to unlock weight loss and better health. Recent research, including new studies published this year, is bringing a more nuanced view to the discussion—offering fresh insights as well as cautionary notes for Thai readers exploring this lifestyle change.

For Thais keeping an eye on health trends, intermittent fasting (IF) has been touted everywhere—from fitness influencers on YouTube to community health clinics. IF typically means limiting food intake to certain windows during the day, such as an 8-hour eating period followed by a 16-hour fast. This approach has been championed for its potential to burn fat, improve metabolic health, and even support longevity.

Ancient “Viking diet” makes a comeback — what the science says and what Thai readers should know before trying it

news nutrition

A renewed interest in an eating pattern billed as the “Viking diet” or “Nordic diet” — a return to whole, locally sourced foods, fatty fish, dairy and preserved staples once eaten by Norse people from the 8th to 11th centuries — is gaining traction on social media and in popular outlets, but experts say modern adopters should separate romantic ideas of Viking hardiness from real nutritional risks and benefits. Coverage in recent lifestyle reporting highlighted practical advice from a registered dietitian and has prompted nutrition researchers to point out that the modern “Viking” revival overlaps substantially with the evidence-based New Nordic Diet (NND), which clinical trials show can improve weight, blood pressure and some lipid markers — yet traditional preservation methods and heavy animal-fat intakes that characterised medieval Norse eating carry cardiovascular and sodium-related risks that deserve attention Fox News / Yahoo and AJCN trial summary.

Viking Feast or Modern Folly: Separating Archaeological Evidence from Diet Fad Hype — Critical Analysis for Thai Readers

news nutrition

Popular media outlets are promoting a renewed interest in the so-called “Viking diet,” presenting it as a path to robust health through traditional Nordic eating patterns, but leading nutritionists and archaeologists are urging caution about romanticizing medieval survival strategies that included dangerously high levels of saturated fat and sodium. Recent investigations into historical Norse eating habits reveal a complex, environment-driven approach to nutrition that emphasized whole foods and preservation techniques essential for surviving harsh climates and long sea voyages, yet experts warn that uncritical adoption of these practices could exacerbate Thailand’s existing burden of cardiovascular disease and hypertension. Scientific research on the modern New Nordic Diet demonstrates genuine health benefits when emphasizing plant-based foods, fatty fish, and whole grains, but these positive effects disappear when traditional preservation methods involving excessive salt and animal fat are included. For Thai readers, this distinction becomes crucial as the kingdom faces rising rates of diet-related chronic diseases that could worsen with the adoption of high-sodium, high-saturated-fat eating patterns marketed under the appealing “Viking warrior” narrative.
