The Whole30 diet declares swaths of food off-limits, and sets up ironclad rules about the little that's left. That means it checks a lot of boxes for a fad diet or one that's too draconian to be effective. But there's good here too, enough that it might help if you know what you're in for.

Private parts are never going to taste like chocolate cake or a glazed doughnut - and that's OK. Men and women's natural smells and tastes are part of human sexuality, and as long as you're healthy, there's nothing wrong with how the universe made you.

But there are a few things you can eat and drink to smell and taste "better".

There were a lot of trendy diets in 2019, including a few even I hadn’t heard of before I started researching this list. Google published the ten most-googled diets, and we’re here to explain what they are and what you might want to know if you’re looking into them.

Fasting is enjoying a surge in popularity, thanks to proponents who claim it activates weight loss. Everyone these days, it seems, is skipping their breakfasts or drinking only water every third day. But is fasting actually good for you? And (more importantly to some) will it make you lose weight?

As we begin a new year and, arguably, a new decade, there are a few things I think we can safely do without. Here are three nutrition myths that I believed, or maybe wanted to believe, at the start of the decade—and why I’m leaving them behind.

Like most guys of a certain vintage, I have mixed feelings about my body. Staying lean and not surrendering to the siren’s call of the dreaded 'Dadbod' is a key concern. But then so is building and maintaining enough muscle so that I can keep up with the young bucks on the soccer field or in the gym.

One of the main keys to success is your diet. You need a meal plan that's high in healthy carbs, fats and proteins. More importantly, it needs to be easy to prepare and affordable - so you'll actually stick to it.

Finding clear, definitive facts about healthy exercise can be difficult. The exercise industry is a multi-billion dollar business, built partially on selling gadgets and supplements to people desperate to lose weight or look attractive. Meanwhile, good workout plans and simple truths lurk in the background waiting for their time to shine. All of this results in lots of misinformation about exercise. We're taking some of those commonly-held exercise myths to task, and we have science to back us up. Let's get started.

Switching to a plant-based diet won't mean you're automatically super healthy. You can eat non-dairy ice cream and frozen veggie pizza every day, but that doesn't mean you're any healthier. There are plenty of plant-based junk foods out there, so if you want to reap the benefits of a plant-based diet, you need to commit to focusing your diet on healthy foods.

Every year, for many, many years, I would promise myself I'd lose weight. Sometimes I would make a little headway, but mostly I didn't. Then in 2017, it happened. Like most huge changes, it was actually lots of little choices adding up to something big. Here's how I did it.

Five people have recently told me they were going to "try keto" — the most recent after gushing about a mutual friend who has been doing keto, aka the popular ketogenic diet, and getting awesome-looking results. You've probably heard rumblings about keto, but what the heck is it? And is it too good to be true?

In this week’s truly heinous edition of Ask Polly, the letter writer casually describes what amounts to multiple attempts on her life by her in-laws. Not only do they refuse to acknowledge her deadly mushroom allergy, they seem to take pleasure in serving them every time she’s over for dinner. Nearly everyone who’s read this column has had the exact same reaction: Holy shit. Are people actually like this?

You can eat well and exercise, but to round out your identity as a Person Who Makes Healthy Choices you may feel like you need to drain a large water bottle a few times a day. The benefits of chugging H2O are myriad and legendary, but are they real?

Kilojoule counts are great if you track what you eat. I also love how kilojoule counts make the ripoff menu items really obvious. If you pay $12 for a 1000kJ salad you’ll be hungry again in, what, five minutes? But not everybody wants kilojoule counts in their face all the time.

Last month, a study found that people who ate “ultra processed” food (think cereal and muffins) ate more calories and gained more weight than those who ate a less processed diet. Ever since, I’ve been using the study’s menus as breakfast inspiration.

The Guinness World Records recently recognised a 116-year-old Japanese woman as the world's oldest living person. Kane Tanaka, who lives in a nursing home in Fukuoka, Japan, enjoys studying maths, waking up at 6am, and loves the strategy board game Othello.

You could spend forever working out exactly how to live a healthy life — the internet is full of hacks meant to help you optimise each little detail. But honestly, most of the benefits of sleep, exercise, and diet come from just doing the basics right. So if you’re feeling overwhelmed, here’s where to start.

Video: To meet some of the most famous old people in the world, I flew to Costa Rica. Where most folks from my flight probably headed straight for the beach, the Lifehacker crew and I drove into the hot, dry hills of the Nicoya peninsula.

Android/iOS: Keeping track of what you eat can help you make better choices, because you know that whatever you choose, you’ll have to write it down. But that doesn’t mean you need to obsess over every kilojoule or ask an app to run weight loss calculations.

If you just want to look for big-picture patterns in your diet, YouAte (free on iOS and Android) is a low key way to do just that.

The majority of eating advice centres on losing weight. Instead, let's look at how changing what you eat can help fend off mid-day energy slumps and blah feelings from your work day.
