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.

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?

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.

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.

The nutrition content of processed food has changed over time. The good news is that: Newer products often have less sugar, less salt, and more fibre. But that's offset by a change in fat content: New cereals, yogurts, and snacks tended to be higher in fat.

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?

Death rates from cancer are down by 27 per cent over the last 25 years, according to a new report from the American Cancer Society. Smoking is a big part of that (lung cancer deaths are way down), and treatments have gotten better over the decades.

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.

Your muscles are made of protein, so if you’re building muscle you need to eat up. But how much protein do you really need? More than a couch potato, but less than the protein-crazy gym bros would have you believe. Here’s how to quickly calculate the real answer.

Stadium food is horrendously expensive and unhealthy, but it's part of the fun of a sports game. And even if you're trying to stick to a diet, you're going to be at the game for a couple hours - so as a human, you're going to have to eat something. Here's how to navigate the world of beer and meat pies.

"I lost 10kg, and I got to eat whatever I wanted!" This is the siren call drawing thousands of people to the nutrition approach known as If It Fits Your Macros, or IIFYM. What started as a way for bodybuilders to cut weight for competition has taken off in the fitness community and beyond. If freedom of choice is important to you, this may be a good fit. But first, release yourself from the delusion that the road to cut abs is paved with waffle fries. It's not quite that easy.

Each year, new weight loss diets appear that promise to reveal the ultimate secret of success – if only you buy the book, pills or potions. Fad diets might achieve short-term results but they are difficult to sustain in the long term.

If you're a self-described "skinny" person trying to put on weight, you probably feel like a second-class citizen when you're researching on the internet. Most fitness information is geared towards fat loss. Let's talk about the basics of healthy weight gain.

Dear Lifehacker, I recently changed careers and now work from home for half the week. How do you plan your eating? Any meal or snack suggestions to keep my energy up and minimise chair flab? I don't want to raid the fridge every time I get munchy, but I don't have a lot of time to cook big breakfasts and lunches either.

There's still a lot we don't know about mental illness, but medical professionals are starting to place more importance on factors like diet and sleep in the treatment of these conditions. A review of the literature has identified some of the best nutrient-rich foods that can aid sufferers of depression and anxiety.

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.

Fat loss relies on one thing: eating fewer calories than you expend. But nobody wants to sit and count calories all day. Most people can learn to track them successfully, but some might need a different strategy altogether. If tracking has given you a headache in the past, consider giving this a try.

I've struggled with my weight for nearly my entire life. I went from being chubby in primary school to overweight in high school to obese in university. At my biggest, I weighed almost 127kg (I'm 168cm tall). Finally, around five years ago, I got a spark of inspiration that ultimately led to me dropping a total of 50kg and counting. Here's how I did it.

Most of us can agree that eating your veggies is a good thing on the nutrition front. Still, simply knowing that vegetables are good for you isn't enough to suddenly turn disgust into undying love for broccoli. But give veggies a proper chance with these tips and you might just learn to love 'em.
