Our findings add to a growing body of evidence suggesting that energy expenditure is consistent across a broad range of lifestyles and cultures. Of course, if we push our bodies hard enough, we can increase our energy expenditure, at least in the short term. But our bodies are complex, dynamic machines, shaped over millions of years of evolution in environments where resources were usually limited; our bodies adapt to our daily routines and find ways to keep overall energy expenditure in check.

All of this means that if we want to end obesity, we need to focus on our diet and reduce the number of calories we eat, particularly the sugars our primate brains have evolved to love. We’re getting fat because we eat too much, not because we’re sedentary. Physical activity is very important for maintaining physical and mental health, but we aren’t going to Jazzercise our way out of the obesity epidemic.

I’m super proud that my co-founder of Sherpaa is Cheryl Swirnow. Cheryl is the magic behind our special Sherpaa sauce. I’m the doctor side of things. She’s the insurance side. Women in tech are exceedingly and unfortunately rare. I have to applaud Women 2.0 in their initiative to raise awareness about this issue and ultimately change the balance in the industry. And I hope that someday we can follow in Etsy’s footsteps and contribute firsthand to helping more women enter tech. 

I just had breakfast with my friend Amit Gupta. He started Photojojo, my favorite photography site on the internet. And 10 months ago, many of you may remember, he was diagnosed with leukemia. In the meantime, the internet came together to save one of our own. He received a bone marrow transplant and is doing very well thanks to an anonymous donor with a perfect match. Hearing Amit talk about life, and specifically time, just made me so, so happy. The vast majority of us don’t consider every day that absolutely every single second counts in this life. We’ll never have to face that realization until we’re old and ready. But when you make it through such a threatening experience, your outlook changes. You become the person we should all be milking every single second out of this wonderful existence.

Thank you Amit.

I’m thrilled to announce that Sherpaa has raised $1.85 million. We’re now that much closer to our mission of making healthcare more accessible and more affordable. 

It’s so obvious that healthcare needs a big change. And it’s even more obvious that the current way of doing things is broken and unsustainable. But there’s a better way for the vast majority of us to experience healthcare. When the stats say that 70% of ER visits are not real emergencies and 70% of traditional office visits could be handled over the phone or via email, it was too much for me to handle. It’s always been my dream to redesign how you go to the doctor and make your life easier. Healthcare is just full of so much possibility and I truly believe it can and will be awesome. But when you don’t have a doctor you can email or call at any time when you’re in a bind, you do the best you can. You go to the ER because it’s accessible or you try and make an appointment with your doctor only to be told the first appointment is next week.

I can’t stand inefficiencies. And I can’t stand sitting around watching this broken system make everyone miserable and broke. So we’re building a company and a team to change that. We will make healthcare better. I’m confident of that. With this money, we’re stepping on the gas hiring an agile team of salespeople and developers to change healthcare. We’ve started in NYC and have plans to expand to other cities like SF, DC, and Chicago.

I couldn’t be happier with the team of investors who believed in Sherpaa:

These guys are simply wonderful people. They’re friends and business partners. They’re fantastically audacious and ridiculously talented. Healthcare is a big fat hairy problem. And they’re willing to put up money, expertise, and their networks to make it better. There aren’t too many success stories in healthcare. But they’re willing to take that bold risk because they want to solve real, human issues that matter to our country. They are the perfect partners.

Bryce, Phin, and Craig…I can’t thank you enough for believing in us. Here’s to making healthcare better. Here’s to building a remarkable company that people love. Here’s to changing lives.

Full speed ahead, Sherpaa.

From my friends at Greatist, 26 Healthy Habits That Really Aren’t So Healthy.

Here’s a smattering:

1. Enhanced water. A little faux fruity flavor might seem like a great way to up H2O intake, but flavored water, like Vitamin Water or even Smart Water, can be filled with sugar. Skip the artificially sweetened water and infuse water with actual fruit.

2. Granola and granola bars. Granola is made from whole grains, so it can’t be bad, right? Not so fast. Granola and granola bars are both calorically dense and often contain a ton of sugar. You may as well eat a candy bar

3. Protein bars. Protein bars don’t fall far from the granola-bar-tree. They are often ultra-high in calories and sugar — not exactly what the body needs after a hard workout. Choose a healthierhigh-protein snack instead.

4. Vitamins and supplements. Multiple studies have shown that taking vitamins (in pill form) may not have any positive effect on long-term health. Researchers have surveyed the nonexistent (or even potentially harmful) ties of vitamin E and C supplements with heart diseasecancer, andcancer treatment[1][2][3]. Plus, most people get all the vitamins they need from their food, and substituting pills for whole foods may mean missing out on the benefits from other compoundsfound in the natural sources.

5. Light beer. News flash: Light-beer doesn’t necessarily mean less calories. Instead, many simply have a lower alcohol content. And for those interested in getting a buzz on, the calorie difference may be negated by the need to drink more. Sip a healthier beer instead, and split up the six-pack between friends.

6. “Low-fat” foods. Think twice before skipping the fat-filled salmon. While cutting some fat could help weight loss, we may miss out on some big benefits from healthy omega-3 fats, such as boosting brainpower and lowering the risk of heart disease[4][5][6].
