With more money in their pockets, Africans are eating more fast food and adopting more sedentary lifestyles, leading to a surge in obesity and associated diseases like diabetes and cancer, experts said on Tuesday.
Rates of obesity and overweight are rising in nearly every country in the world, the Global Nutrition Report said, describing malnutrition as the "new normal".
One in three people worldwide are experiencing malnutrition, it said, with 44 percent of countries facing serious levels of both undernutrition and obesity.
Obesity is a form of malnutrition as the body does not receive sufficient nutrients and people have too much salt, sugar or cholesterol in their blood.
"Many countries now across the continent are facing a double burden of malnutrition," Shane Norris, a nutrition expert at the University of Witwatersrand in South Africa, told the Thomson Reuters Foundation in a phone interview.
"There's still persistent undernutrition in early life and overweight and obesity in later life."
While undernutrition is falling globally, few countries are succeeding in tackling obesity and the four main non-communicable diseases (NCD) linked to it: diabetes, cancer, cardiovascular diseases and chronic respiratory diseases.
NCDs are projected to become the leading cause of death in sub-Saharan Africa by 2030, according to the World Bank.
South Africa is the most obese country in sub-Saharan Africa, Norris said, with over 40 percent of adults overweight or obese.
Other rapidly urbanising African countries are following suit, with middle classes often queuing at fashionable fast food restaurants like Kentucky Fried Chicken.
"The malls are the 'in' thing," said Zachary Muriuki, a nutritionist specialising in diabetes with Kenya's health ministry.
"We are seeing a trend of obesity cases rising," he said, blaming unhealthy diets and increased use of cars.
In Kenya, 84 percent of people always or often add sugar to their food and drinks, while 94 percent of people eat less than the recommended five portions of fruit and vegetables a day, government data shows.
Culture also plays a role, particularly for women who are seen as successful, happily married and healthy when they are overweight, experts said.
"Being overweight is seen as a positive thing," said Norris, adding that South Africans believe it means someone does not have HIV/AIDS, which often leads to weight loss.
The report called for donors to spend more on non-communicable diseases, which accounted for less than two percent of their health spending in 2014.
Testing and treatment for malaria and HIV/AIDS is often free, which is not the case for NCDs, Muriuki said.
Non-communicable diseases account for half of hospital admissions in Kenya, the government says.
"Long term management of these diseases is very expensive," Muriuki said. "We are struggling as a country, trying to manage cancer. We have cases and cases in our hospitals lining up to go through chemotherapy."
