How one can Eat for Your Health — And the Planet’s Health, Too

For individuals with diabetes, eating a healthy weight loss plan doesn’t need to conflict with environmental sustainability. In truth, the 2 could also be complementary — whilst concerns about planetary health are growing. 



How will we feed a healthy and sustainable weight loss plan to an estimated 10 billion people in 2050? That issue has been driving the EAT-Lancet Commission on Food, Planet, Health since 2019. The group, led by Walter Willett, DrPH, professor of epidemiology and nutrition at Harvard’s T.H. Chan School of Public Health, believes it now has the framework for what they call a “planetary health weight loss plan.”

We spoke with Dr. Willett to learn more concerning the planetary health weight loss plan and the way it overlaps — or perhaps doesn’t — with a healthy diabetes weight loss plan. 

The research has led Willett to consider that there’s no way humans can proceed the present approach to food systems, with diets so fixated on processed foods and beef. Our modern eating pattern is each bad for our health and terrible for the environment.

“The large, fundamental threat to human civilization is the speed of climate change that we’re experiencing now,” he said. “In the long run, we will’t be healthy with no healthy planet. The best way we’re producing our foods and what we eat is driving climate change.”

What Exactly Is the Planetary Health Weight loss plan?

The very first thing to know is that there isn’t any precise formula for the weight loss plan. As a substitute, the planetary health weight loss plan is what Willett called a dietary pattern targeted for a healthy population emphasizing modest amounts of animal protein, with the balance being whole grains, fruits, vegetables, and legumes. 

The commission does offer, nevertheless, a way of the proportionality of what a plate of food inside this framework would seem like:

“A planetary health plate should consist by volume of roughly half a plate of vegetables and fruits; the opposite half, displayed by contribution to calories, should consist of primarily whole grains, plant protein sources, unsaturated plant oils, and (optionally) modest amounts of animal sources of protein.”

Willett explained that the weight loss plan “minimizes risks of noncommunicable diseases, including heart problems, diabetes, cancer, and other conditions, and in addition stays inside planetary boundaries.”

He noted the researchers went through all of the foremost food groups one after the other, asking what could be the optimal intake of grains — specifically whole grains — in addition to fruits, vegetables, beef and plant protein sources, added fats, added sugar, and salt. Using existing scientific evidence, the commission developed global scientific targets for each healthy diets and sustainable food production. That’s the premise for a planetary health weight loss plan. 

“Interestingly, after taking a look at all of the world’s literature after we put all of it together, it was very consistent with a standard Mediterranean weight loss plan,” he said, although he also refers to it as a flexitarian weight loss plan.

Willett did praise the American Diabetes Association (ADA)’s approach. “The ADA already has what would qualify as a planetary health weight loss plan. It leans more toward the plant-based a part of the image.”

The researchers sought to develop an intersection between what they call a “protected operating space for food systems” where healthy and sustainable diets meet across the globe. The underside line is a largely plant-based weight loss plan that would also include modest amounts of fish, meat, and dairy. 

Not only is that this a weight loss plan that would prevent 11 million deaths a yr, however the associated food production parameters also could potentially decrease the chance of “irreversible and potentially catastrophic shifts within the Earth system,” in accordance with the EAT-Lancet Commission report.  

How Does the Planetary Health Weight loss plan Work for People With Diabetes?

In case you have a look at expert resources just like the ADA, there isn’t any one weight loss plan really useful for people managing diabetes, whether type 1 or 2. However it does have some common guidelines:

  • Eat loads of nonstarchy vegetables.
  • Eat less sugar and fewer refined grains.
  • Select whole foods over highly processed foods.

And, after all, there’s the admonition to eat fewer carbs to enhance blood sugar. In truth, the ADA has noted that we don’t truly need carbs.

Willett doesn’t go that far, but he did tell Healio, “You don’t really need to have any grains in a weight loss plan.” In our discussion, he explained that humans could make enough glucose from protein for the central nervous system’s use of glucose but said that a no-grains approach was extreme. Whole grains offer a number of positive advantages, equivalent to fiber and micronutrients.

“But for somebody with diabetes who would really like to actually go together with a low-carbohydrate weight loss plan, you can do this by pondering of, for instance, plant sources of protein,” Willett said. “Soy has a modest amount of carbohydrate and has quite a little bit of protein. You’ll be able to eat healthy fats by eating nuts, which have little or no carbohydrate.”

Willett said that while the planetary health weight loss plan approach is geared to a “generally healthy population,” it will be useful to individuals with diabetes, especially type 2 diabetes.

“It involves a moderate intake of carbohydrates and fat, but there’s a number of attention to the standard of carbohydrates,” he explained, “really minimizing refined grains and emphasizing whole grains and small amounts of potatoes, which have a high glycemic index.”

For individuals with type 1 diabetes, Willett acknowledged, “We don’t really have enough data that’s specifically derived for individuals with type 1 diabetes to say that we’ve evidence that the planetary health type plan can be good for somebody with type 1 diabetes.”

“But still,” he continued, “I feel it’s very likely that a weight loss plan more plant-forward, emphasizing plant protein sources, is more likely to be good for an individual with type 1 diabetes, since it does mean that carbohydrate intake can be modest, and includes healthier fats and healthier sources of protein for anyone who’s at higher risk of heart problems. This makes it very likely that this could be good for somebody who has type 1 diabetes as well.”

Designing a Diabetes-Friendly Planetary Health Weight loss plan

In fact, we want to acknowledge that each one plants aren’t equal with regards to the glycemic index. Some, like potatoes, bananas, sweet potatoes, and watermelon, rank pretty high. For an individual without diabetes, that will not be a difficulty, but individuals with diabetes still needs to be focused on vegetables and fruits with a lower glycemic index and limit portions of those which can be higher. So, for individuals with diabetes, a planetary health weight loss plan doesn’t confer free-for-all consumption of plant-based foods.

Beyond that, provided that the planetary health weight loss plan is actually flexitarian, individuals with diabetes already weighing selections just like the Mediterranean weight loss plan or keto weight loss plan could make those work inside the planetary health weight loss plan framework.

“It really comes right down to about two servings of animal source protein a day that could possibly be a part of a planetary health weight loss plan, with one serving of dairy, one other serving of poultry or fish or eggs, with beef kept at no multiple serving every week because that has a extremely big planetary health impact. But there’s an enormous amount of flexibility there.”

Yes, he said, a keto weight loss plan is on the table — but with a twist.

“The largest threat for most individuals with diabetes is excessive increases in heart problems,” Willett said, “and high consumption of saturated fat was related to increases in heart problems amongst individuals who already had diabetes. But you can have the metabolic advantages of a keto weight loss plan, but emphasizing plant sources of protein, including nuts. Replacing beef with nuts is something I feel just about everybody should consider as a priority.”

For those on medications like Ozempic, which has the effect of reducing appetite, that could possibly be a profit to planetary health if it reduced food production and led to healthier people.

“If everybody ate just slightly bit less, that may be good for the planet,” Willett acknowledged, “especially those that are chubby or obese. In fact, it’s still very necessary what we eat. The final point is that these drugs will profit some people, but current prices are an enormous issue. More fundamentally, after we have a look at weight loss plan and health overall, excessive weight is clearly an issue. But when everyone did shed weight and still ate the present American weight loss plan, they’d still not be healthy. It’s the standard of the weight loss plan in addition to exercise.”

Are the EAT-Lancet Commission researchers on a path toward developing examples of planetary health diets for healthcare professionals and consumers? Well, it’s complicated. It’s a world initiative, and the perfect weight loss plan in Central Africa can be different from those in South America and Northern Europe, not to say the various regions of america. After which there’s the problem of drilling right down to diets for individuals with health conditions that require dietary restrictions. 

“We haven’t specifically had an agenda to have a look at individuals with clinically specific issues like diabetes, and that may be a superb thing to do,” said Willett.
