Weight LossMar 15, 2026
Most people trying 16:8 fasting want to know one thing: what will actually be different in a month? The honest answer from clinical trials is that the changes are real but modest. Overweight adults who stick with a 16-hour fast and 8-hour eating window for about four weeks typically lose roughly 1 to 2 kilograms, with small but measurable improvements in insulin sensitivity and triglycerides. That's not nothing. But it's also not dramatic, and it depends heavily on whether you actually eat less overall.
The less comfortable truth is that the eating window itself isn't magic. Several large trials found that when people kept their total calorie intake the same, weight loss from 16:8 looked no different from ordinary dieting. The window works primarily because it makes it easier to eat less. If it doesn't do that for you, the scale probably won't move much.
ColonoscopyMar 15, 2026
Most people assume colonoscopy prep means days of dietary misery. The research tells a different story. For generally healthy, average-risk outpatients using a modern split-dose bowel prep, prospective data show no association between what you eat 2 to 3 days before the procedure and how clean your bowel ends up being.
That means the restrictive eating many people dread can usually be compressed into a single day, not two or three. Several randomized trials and meta-analyses back this up: extending a low-residue or low-fiber diet beyond one day before the colonoscopy does not improve prep quality. It just makes the whole process harder to follow.

Potassium gluconate is one of the most bioavailable supplemental forms of potassium you can take, with absorption efficiency above 94%, putting it on par with whole food sources like potatoes. That's the good news. The less exciting part: in short-term human trials, supplementing with it at moderate doses didn't meaningfully move the needle on blood pressure or vascular function. So what is it actually useful for?
The answer depends on what you're trying to accomplish. If you need to correct low potassium, the evidence supports it clearly. If you're hoping a potassium supplement will replace dietary potassium and deliver the same cardiovascular benefits, the picture is murkier.

Protein bars can be a healthy, convenient protein source, but many commercial options are loaded with added sugars, unhealthy fats, and additives that undermine their supposed health benefits. A study of foods with protein claims in Spain found that products carrying protein labels were actually 13% more likely to be classified as "less healthy" by objective nutrient profiling standards than products without such claims.
The word "protein" on the package doesn't guarantee you're making a good choice. This article will walk you through exactly what to look for when you flip that bar over, with specific numbers and red flags backed by clinical research.
Gastrointestinal HealthMar 15, 2026
A small clinical trial found no extra symptom benefit when lactose-intolerant adults ate lactose-free yogurt compared to regular yogurt, as long as both contained high levels of live cultures. That finding reframes the entire conversation. Regular yogurt is already naturally lower in lactose than milk, and its bacteria actively help break down whatever lactose remains.
That doesn't make lactose-free yogurt pointless. It does mean the decision is more nuanced than "I'm lactose intolerant, so I need the lactose-free version." Here's what the research actually supports.
Healthy EatingMar 15, 2026
The most effective vegetarian dinners aren't exotic or complicated. They're the meals you already make, with the meat swapped out. Research on plant-based versions of familiar dishes like lasagne, chilli, stir-fries, and curries finds they tend to have better nutrient profiles than their meat-based counterparts, while costing less and producing fewer emissions.
That last point is worth sitting with. You don't need a new cookbook or a pantry overhaul. You need lentils where the mince used to be.
Lung CancerMar 13, 2026
People eating the most ultra-processed food face roughly 40% higher lung cancer risk compared to those eating the least. That finding comes from a large US clinical trial and held for both non-small cell and small cell lung cancer, the two major types. Smoking is still the overwhelming driver of lung cancer, but the accumulating evidence suggests your grocery cart matters too.
The research is all observational, meaning it can't prove cause and effect on its own. But the signal keeps showing up across different populations, different study designs, and different ways of measuring diet. And for processed meat specifically, genetic analysis is starting to support a causal connection.
