what it claims

Simplify your nutrition by avoiding extremes (such as the beef tallow trend) to focus on sustainable habits: reducing ultra-processed products and prioritizing whole, balanced foods.

The call to simplify one's diet by reducing ultra-processed products in favor of whole foods is solidly supported by modern science.

The call to simplify one's diet by reducing ultra-processed products in favor of whole foods is solidly supported by modern science. A comprehensive systematic review published in the BMJ by Lane et al. (2024, level of evidence: review of meta-analyses) directly associates the reduction of these industrial products with improved overall vitality. Regarding the use of beef tallow as a wellness aid, research remains skeptical: a meta-analysis by Mozaffarian in PLOS Medicine (2016) shows that replacing animal saturated fats with plant-based unsaturated fats promotes better metabolic health. Furthermore, the observational study by the American Gut Project conducted by McDonald et al. (2018) confirms that it is the diversity of plant fibers, rather than pure animal fats, that optimally supports the gut microbiota. Returning to a simple, varied diet rich in unprocessed products is therefore the most robust long-term strategy.

Expose yourself to daylight and spend time outdoors early in the morning to improve your overall health and vitality.

Deep imbalances in our vitality are set in motion years before visible warning signs appear; to preserve overall health, one must take proactive steps through a personalized, anti-inflammatory lifestyle based on three pillars: consuming 30 different plants per week, sleeping more than 7 hours per night, and engaging in regular physical activity.

One should not pit proteins against fiber: for optimal intestinal comfort, it is advisable to combine these two nutrients, because an excess of protein not compensated for by fiber leads to less favorable bacterial fermentation in the colon.

Others on this

Cutting back on the classic ultra-processed staples (soda, packaged chips, sugary cereal) remains one of the better-supported dietary levers — just without the drama: the long-term risk association is real and reproduced, not an immediate sentence for one indulgence now and then.

If you use protein powder, pair it with whole foods for fiber, and choose it on quality criteria: a short ingredient list, no unnecessary sweeteners or additives, and third-party testing.

If you deep-fry often or eat restaurant fried food regularly, favor a more heat-stable oil (olive, avocado) over reusing the same oil repeatedly or pushing it to very high heat: repeated heat and reuse are the real issue, not seed oil itself.

To overcome impulsive sugar cravings, it is advised to understand one's emotional triggers, consume enough protein and starchy foods at meals to maximize satiety, eliminate ultra-processed products from one's immediate environment, and use distraction or hygiene techniques (such as brushing one's teeth).

Fast food items like the Big Mac are not inherently harmful if consumed occasionally and in moderation, and if they fit into an overall healthy, balanced, and nutrient-rich diet.
