Eating less certainly seemed to help the monkeys, but calorie restriction is much tougher for people out in the real world. For one, our access to regular, high-calorie meals is now easier than ever; with companies like Deliveroo and UberEats, there is no longer a need to walk to the restaurant anymore. And two, gaining weight simply comes more naturally to some people. And then someone else walks past a table with a cake on it and they have to go up a pant size. Ideally, the amount and types of food we eat should be tailored to who we are — our genetic predisposition to gaining weight, how we metabolise sugars, how we store fat, and other physiological fluxes that are beyond the scope of scientific instruction at the moment, and perhaps forever.
Eating Right Isn't Complicated
But a predisposition to obesity can be used as a guide to life choices rather than an inevitability. Not only has Roberts seen the problems of obesity first-hand in her family, she knows the benefits of CR better than most. Over two years, healthy men and women aged between 21 and 50 years were split into two groups. Both had health checks every six months. But the Calerie trials tested for the next best thing: the early biological signs of heart disease, cancer, and diabetes.
Published in , the results after two years were very positive.

Admittedly, some benefits may come from weight-loss. Earlier trials from Calerie had included people that were obese as well as those with a healthy body mass index BMI of 25 or below, and slimming down would have certainly improved the welfare of the heavier participants.
Diseases and disorders previously thought to be age-associated diseases are now popping up in the obese population, she adds. That is, someone whose BMI lies between Despite these results, evidence from further trials will be needed before someone with an already healthy BMI should be advised to reduce their calorie intake. And anyone wanting to change their diet would be advised to consult a medical professional beforehand.

In the meantime, the scientists will be hoping that their rhesus macaques may help us to understand exactly why calories restriction may have these effects. With nearly 30 years of data on lives and deaths, and blood and tissue samples, from nearly monkeys, the work at NIA and the University of Wisconsin aim to shine a light into the black box of calorie restriction, illuminating just how it delays ageing.
With less food, is the metabolism forced to be more efficient with what it has? Is there a common molecular switch regulating ageing that is turned on or off with fewer calories? Or is there an as of yet unknown mechanism underpinning our lives and deaths? The importance of monkeys like Sherman far outspans their lives.
Answers to such questions might be long in coming. Ageing could be treated directly, that is, without the need of calorie restriction. Although lacking a neat explanation, calorie restriction is one of the most promising avenues for improving health and how long it lasts in our lives. One expected issue was a slight decrease in bone density that is often tied to gradual weight loss, says Roberts. But as a precaution, volunteers were provided with small calcium supplements throughout the trial.

I think that delaying the progression of chronic diseases is something that everyone can get behind and get excited about, because nobody wants to live life with one of those.

The results show that ageing itself is a reasonable target for clinical intervention and medical treatment — Rozalyn Anderson. Significant health benefits may be garnered in an already healthy body, but further trials are needed. Calorie restriction may be one of the most promising avenues for improving health and how long it lasts in our lives.

For example, eat whole-wheat bread instead of white bread. Read the ingredients list and choose products that list a whole-grain ingredients first. Look for things like: "whole wheat," "brown rice," "bulgur," "buckwheat," "oatmeal," "rolled oats," quinoa," or "wild rice. Choose a variety of lean protein foods: Meat, poultry, seafood, dry beans or peas, eggs, nuts, and seeds are considered part of the protein foods group.
Compare sodium in foods: Use the Nutrition Facts label to choose lower sodium versions of foods like soup, bread, and frozen meals. Select canned foods labeled "low sodium," "reduced sodium," or "no salt added. Drink water instead of sugary drinks: Cut calories by drinking water or unsweetened beverages. Soda, energy drinks, and sports drinks are a major source of added sugar and calories in American diets. Eat some seafood: Seafood includes fish such as salmon, tuna, and trout and shellfish such as crab, mussels, and oysters.
Seafood has protein, minerals, and omega-3 fatty acids heart-healthy fat. Adults should try to eat at least eight ounces a week of a variety of seafood. Children can eat smaller amounts of seafood, too. Cut back on solid fats: Eat fewer foods that contain solid fats.
