Excess carbs at lunchtime from sandwiches, pasta salad or any sort of cake or chocolate bar cause blood sugar levels to rise too quickly, insulin then gets produced to bring down the blood sugar levels and this leads to the slump.

The solution is to have a higher protein lunch and have beans, lentils and chick peas or brown rice as a carbohydrate source rather than bread pasta and cakes.

There are the obvious caffeine containing stimulant energy drinks like red bull that can help boost your energy levels, if you must have one of these in an emergency then have the no-sugar option.

The amino acid tyrosine available in powder and capsules can help increase alertness in the afternoon and can be used regularly.

However if you address the underlying cause and reduce your carb intake then you won’t need the additional measures and expense of caffeinated drinks and supplements.

You can’t out train a poor diet comes to mind.

I always say that to lose weight you need to focus on your diet first if weight loss is your goal. When health professionals talk about kids being too sedentary and spending too much times on video games, that is not the reason in my opinion why they are fat.

At my sons school, I see the fat kids running around at play time and after school, I see those same kids parents walking home with Dominos Pizzas. My pop science experiment draws he same conclusions as this study.

News: Exercise Doesn’t Always Lead to Weight Loss Health and Fitness Articles, News, and Tips – Greatist.com News: Exercise Doesn’t Always Lead to Weight Loss

That second cupcake is A-OK if we hit the gym later… right? Well, not so fast. New research suggests exercise might not be the key to weight loss[1]. According to the researchers, with the exception of elite athletes (like Olympians), humans burn pretty much the same amount of energy every day no matter what kind of exercise they do. If we can’t affect the output, then input is even more important. The study authors say it’s more important to focus on how much energy — aka how many calories, aka how many cupcakes — we put into our bodies.

The Study

Herman Pontzer and a team of Hunter College anthropologists compared daily energy expenditures in the Hadza (a modern hunter-gatherer tribe in Africa) and Western populations, who had much more sedentary lifestyles[2]. As researchers expected, the Hadza were more active than their laptop-loving Western counterparts. But here’s the kicker: When researchers measured how much energy each group spent on a daily basis, it turned out the Hadza tribe burned roughly the same amount as their Western counterparts.

Sound strange? Apparently humans burn roughly the same amount of energy every day no matter what kind of physical exercise we do. Instead, the researchers think the Hadza people’s bodies were able to spend extra energy on physical activity by conserving energy elsewhere, like on biological processes that take place inside cells. Based on these results, researchers say people who want to lose weight should focus more on how many calories they consume and less on how many they burn. And, despite what many health organizations claim, modern sedentary lifestyles might not be the sole cause of the obesity epidemic.

Can We Trust It?

It’s hard to compare the Hadza tribe to modern-day Westerners because their physical activity and diet are so different from the kind we do at the local gym. But that difference may not matter. Pontzer says he has reason to believe humans have been spending roughly the same amount of calories per day today for 100,000 years.

These findings aren’t totally isolated, with other research suggesting exercise interventions generally don’t help people lose weight[3].

But it’s too soon to start mass-cancelling our gym memberships. “Obesity is only one aspect of health,” Pontzer said, adding that exercise can also improve mental health and immune system function. And the concept of a set metabolic rate doesn’t necessarily apply to high-functioning athletes like Michael Phelps, who can burn as many as 8,000 calories a day.

Greatist Expert and cardiologist John Mandrola says neither exercise nor diet holds the solution to obesity: “Truly good health, or wellness, comes only when humans use their body and then feed it smartly each day.”

Usually it is they have been watching the UFC, last week I got a new answer it was I read a blog post by SAm Harris the blogger.

I’ve never heard of Sam Harris so I looked up the blog post,

The main point of the blog post that I got from it was that BJJ unlike other Martial Arts can be trained at 100% and stress tested in reality. I’m a Karate Brown belt and when we did sparring sessions we had to control our punches and kicks otherwise you would end up black and blue, so you don’t really get the feel of what would actually happen in a real fight.

The second take away for me was that when you test drills, punches and combinations in other sports your partner is complicit and will often ‘go with the move’, while this happens in BJJ, you soon have the opportunity to test the new move in a full on sparring session to see if it works.

Here is Sam’s blog post.
