How many carbs should I eat during a marathon?

The wall is not inevitable. Most marathoners can avoid the bonk with 30 to 90g of carbs per hour. Here is how many carbs to eat during a marathon and when.

psychology

How do you know if your macro tracking has become disordered?

The line between disciplined tracking and disordered eating isn't always obvious. Some patterns are clearly healthy, some clearly problematic, and a real grey zone exists. Warning signs and self-reflection inside.

tracking

When should you stop tracking macros?

Most macro-tracking advice assumes you'll track forever. The honest answer is that tracking is a tool with a job to do. Here are the signs the job is done and you can graduate — without losing the body composition gains.

protein

How much protein do you actually need?

Across 641 days of fully logged food, calories landed almost exactly on target and protein did not. Everyone who missed was in a calorie deficit, which is the group where protein matters most.

tracking

How do you track macros if you work night shifts or rotating schedules?

How to track macros for shift workers when your day starts at night. Fix the streak math, calorie timing, and meal labels for rotating or night schedules.

sleep

What should you eat for better sleep?

Specific foods and meal patterns measurably affect sleep quality. Not magic, not dramatic, but real. Here's the evidence-based playbook for using nutrition to support sleep, plus what to avoid.

sleep

How does sleep deprivation affect macros and body composition?

One bad night changes your hunger, cravings, metabolism, and training for 24-48 hours. Chronic poor sleep undoes most body composition work that good macros are supposed to produce. The science and fix.

metabolic

How does training affect insulin sensitivity?

Training is one of the most powerful ways to improve insulin sensitivity, often beating diet alone. Here is how strength work and cardio change your metabolism.

metabolic

What does a continuous glucose monitor actually tell you?

CGM data is heavily marketed as a window into metabolic health. For non-diabetic athletes, most of what a CGM reveals is normal physiology, not actionable insight. Here's what the data actually means and where the value is.

metabolic

Should non-diabetics worry about glucose spikes after meals?

CGMs made post-meal glucose spikes visible to everyone, but should non-diabetics worry about them? Here's the honest, research-based read for healthy adults.

protein

What should I buy at the grocery store to hit my protein target?

A high-protein grocery list organized by how much protein each item delivers per realistic serving, so hitting your target becomes the default, not a daily project.

protein

Can you hit a high protein target without protein powder?

Protein powder is convenient and optional. If you would rather eat food, here is how the numbers work out across a day, and which whole foods carry the most weight per serving.

protein

How do you eat 150 grams of protein in a day?

Knowing your protein target is easy. Hitting it every day is the part that fails. Here is the arithmetic, a day that adds up, and the three structural fixes that make 150g routine instead of a daily scramble.

training

Does lifting weights improve bone density?

Bone responds to mechanical load, which makes resistance training one of the few genuine levers on bone density. The research also shows that the intensity most people train at is too low to trigger it.

training

Does muscle soreness mean the workout worked?

No. Soreness tracks novelty far more than it tracks stimulus, and using it to judge a session will push you toward random training and away from the thing that actually builds muscle.

body composition

How long does body recomposition take?

Body recomposition is real but slower than the photos suggest. Here is a realistic timeline, who it works fastest for, and what to track while the scale holds.

training

Is lifting twice a week enough to build muscle?

Two lifting sessions a week is enough to build muscle if they carry enough total work. Here is what the research on training frequency actually shows.

body composition

Will lifting heavy weights make a woman bulky?

The bulky fear keeps women in the 5lb dumbbell section for years. Here is what the research on sex differences in muscle growth actually shows, and why the look people are afraid of is harder to build than they think.

training

What is progressive overload and how do you actually apply it?

Progressive overload is the one principle that decides whether you build muscle. Here is what it means and the five ways to actually apply it in training.

Does creatine cause hair loss or harm your kidneys? See where these common myths came from and what the research actually supports for healthy people.

supplements

Do you need to do a creatine loading phase?

Do you need to load creatine? Loading saturates your muscles in about a week instead of a month. That speed is the only thing it actually buys you.

supplements

Does creatine make you bloated or gain water weight?

The bloating fear keeps a lot of people off creatine. The honest answer: the water is drawn into the muscle, not under the skin, and the loading phase causes the version people actually notice.

body composition

Why did the scale go up when I started lifting weights?

The scale going up when you start lifting weights is water, not fat. Here is exactly what is happening and how long it takes to settle back down.

supplements

Women over 40 need 3 to 5 grams of creatine monohydrate daily, no loading or timing tricks. Here is the exact dose and what the research shows for women who lift.

protein

How should protein intake change as you age?

How your protein needs by age really shift: total intake stays similar, but aging muscle needs a bigger per-meal dose to respond. Here is what changes and why.

training

What should you eat after a race or competition?

Recovery nutrition after a race or competition, from glycogen to protein timing. What to eat in the first 24 to 72 hours, and what athletes get wrong.

sleep

Why am I so hungry and craving carbs after a bad night of sleep?

After a short night, ghrelin rises and leptin drops, so cravings after bad sleep are hormonal, not weak willpower. Here's how to manage them calmly.

tracking

Why is maintaining body composition harder than losing weight?

Most people regain weight after a cut because maintenance has no daily target or feedback signal. Here is why maintaining weight is harder, and how to hold it.

tracking

How do you track macros if you have ADHD?

Standard advice ignores the executive-function tax of logging meals all day. Here is how tracking macros with ADHD actually works, or how to skip it without losing results.

protein

Can plant-based eaters successfully follow protein maxing?

Plant proteins have lower amino acid completeness and slightly lower digestibility than animal proteins. That doesn't mean plant-based protein maxing fails. It means the math has to be adjusted by about 15-20%. Here's how.

Is the Mediterranean diet good for athletes?

The Mediterranean diet has the strongest research base of any eating pattern for long-term health. Adapting it for athletic needs (more protein, calories, training-time carbs) preserves the benefits.

protein

Does protein maxing actually work, or is it a TikTok myth?

Protein maxing is the social media trend of eating 200-300g of protein daily. The research consensus is that 0.7-1.0 g/lb works for almost everyone. Here's the honest read on the gap between trend and evidence.

diet

Should athletes eat keto?

Keto works for some athletic profiles and poorly for others. The evidence is clearer than the social media debate suggests. Here's who benefits from ketogenic eating, who doesn't, and what to expect.

nutrition

How do you eat healthy after recovering from disordered eating?

In stable recovery, standard macro advice can backfire. Here's how to approach healthy eating after disordered eating with regularity, not optimization.

protein

What are the actual signs you're eating too much protein?

Most 'high protein' warnings fear-monger about kidneys. The actual signs of overdoing protein in healthy adults are subtler: GI symptoms, food monotony, displaced carbs, worse training. Here's what to watch for.
