Carrying around a little extra body weight — like at least two-thirds of all Americans do — can change what types of activities may be best for you to get involved in. Getting started is as easy as getting up from your chair and moving more often. Keeping going means that you may need to focus on doing lower impact activities that put less stress on your lower limbs.
If you have arthritis in your hips or knees, that may also change what you choose to do. Rest assured that you can find some appropriate activities and find out more about being active in this chapter. You may even lose some weight as a result — and get tips on how to keep it off for good.
You may have heard that gaining weight is what caused your prediabetes or type 2 diabetes. But it’s just as likely or even more likely that your weight gain is just a symptom associated with insulin resistance, prediabetes, and diabetes rather than a direct cause. It’s possible to become insulin sensitive without losing much or any weight. However, having excess body fat does have its downside. The following sections help you understand how that additional weight, particularly fat, can affect your health.
As your body weight increases, so does your risk of dying from heart disease or developing type 2 diabetes. However, the more physically fit you are, the lower your risk of dying from any cause is — even if you’re overweight.
When you store fat just in fat cells (particularly just under the skin, as subcutaneous fat), you aren’t likely to have as many health problems compared to when your body puts it in other places. If you store most of your fat in your hips (making you pear-shaped), you may be perfectly healthy, metabolically speaking. Being shaped more like an apple with fat around your middle, however, can be the indicator of many problems with your metabolism — and health issues in your future if you don’t do what you can to prevent them with changes in your lifestyle.
Storing excess fat within your belly (as visceral fat) is undeniably bad for your health. Having a lot of visceral fat increases your risk for heart disease, high blood pressure, and even type 2 diabetes. The spillover of excess fat into organs like the liver or heart is what damages them. (Head to the later section “Storing less fat in your liver” for more on how fat affects the liver.) If you can put those excess calories as fat in your fat cells instead, you can actually prevent or delay these harmful effects.
Your muscles also store extra fat as you get heavier, and that can make your muscles more resistant to insulin. Because your muscles are responsible for most blood glucose use orchestrated by insulin in your blood, developing insulin-resistant muscles has a substantial negative impact on your blood glucose. And the only remedy appears to be exercising regularly.
Regular exercisers, paradoxically, can store more fat in their muscles without getting insulin resistant. Athletes have large amounts of fat stored inside their muscle fibers, and they’re extremely insulin sensitive for the most part. That alone tells you that the total amount of fat stored there isn’t as critical as whether you’re staying active, although exercising may impact the types of fat packed away in muscles and how they’re stored there.
Storing extra fat in your liver may contribute to low-level inflammation throughout your body, and that inflammation is what is believed to lead to insulin resistance, type 2 diabetes, heart disease, and other metabolic health problems. So your liver (and whether it has excess fat in it) may prove to be a crucial link between weight gain and prediabetes or type 2 diabetes.
When packed with fat, your liver gets resistant to insulin, and that can lead your liver to release too much glucose into your blood overnight (among other bad effects). Having an insulin-resistant liver may cause elevated blood fats and cholesterol levels that contribute to the development of heart disease. You can compound the problem with dietary choices that contribute to your liver’s insulin resistance, including foods that are highly processed, contain excess calories, or are consumed in large portions.
Many people decide to be physically active to help them lose weight and improve their body shape. Regular physical activity makes a huge difference in whether you gain weight, keep the same weight, or lose more. The lifestyle behaviors that help you keep your weight down (like regular exercise) are likely to improve your diabetes management as an added benefit.
Regardless of how much weight you lose or don’t lose by being active, being regularly active can prevent you from developing type 2 diabetes in the first place or reverse prediabetes. Losing weight can also help manage diabetes in people, regardless of what type they have.
The Diabetes Prevention Program (a lifestyle management program designed to prevent type 2 diabetes) study found that weight loss is most directly associated with lower risk of getting type 2. But in the study, participants’ weight loss was predicted by how much exercise they did daily, and only the ones who continued to exercise around 60 minutes a day — most just by walking — after the study ended maintained their new, lower body weights. The rest who were sedentary gained most or all the weight back over time.
Remember, you can become more fit regardless of your body weight. You can also gain almost all the health benefits of having a higher fitness level without struggling to lose weight and keep it off. Both moderate aerobic exercise and resistance training help you lose belly (visceral) fat that dieting alone can’t. (I discuss these kinds of exercises in Chapters 10 and 11, respectively.)
How can you get more active when you’re sedentary and overweight? Most activities are possible, but ease into being more active by taking small steps in that direction. It’s not a race to the finish; you’re just trying to establish a lifetime habit of being more active.
Getting active with extra body weight is all about starting out slowly and progressing slowly for the best results. You want to get fit and possibly lose some weight along the way. It’s possible if you go about it the right way.
As with all things, if you enjoy doing something, you’re more likely to continue doing it over time. This concept is critically important with physical activities and even more so if you’re trying to manage your weight. If you hate doing an activity, eventually you come up with one excuse or another to stop. When you’re packing some extra weight, doing any activity can feel harder than it might be when you’ve lost a few pounds.
Carrying extra body fat raises your chances of getting arthritis (osteoarthritis being the most common type that develops with aging) in your hips, knees, and ankles, which may limit your ability to exercise. Despite that, being active is an effective means of managing arthritis, including the more severe rheumatoid type (which is an autoimmune condition like type 1 diabetes), and its associated discomfort. Being active can make your pain and discomfort less over time instead of aggravating it.
Start with basic range-of-motion exercises (including stretching) to increase your joint mobility. Later you can include specific resistance exercises that strengthen the muscles surrounding your affected joints. Doing so also helps you maintain your leg strength, which is critical to basic movements like getting up out of a chair, climbing stairs, and walking.
Doing moderate aerobic activity that is weight-bearing (like walking) can reduce arthritis pain in hips and knees. If you have arthritic knees or hips and don’t enjoy walking because it’s too uncomfortable or painful, you can choose to do non-weight-bearing activities instead.
If you have arthritis in your lower extremities, also consider the following options:
You may also want to seek out a physical therapist, athletic trainer, personal trainer, or other fitness professional to help you design an exercise program specific to your needs.
After exercising, you may want to apply ice to your joints (particularly your knees) for 15 to 20 minutes to reduce swelling and help prevent undue soreness. In addition, consider taking nonsteroidal anti-inflammatory medications (NSAIDs) like aspirin or ibuprofen to lessen any residual discomfort, but avoid taking them if your kidneys are not working well. Check with your doctor if your arthritis pain becomes worse over time, and avoid activities that feel like they make your joints more painful.
Having diabetes increases your risk of experiencing joint-related injuries and overuse problems like tendinitis. Choosing a more moderate exercise like walking rather than jogging or running may be prudent to reduce the potential for joint trauma.
Diabetic frozen shoulder, trigger finger, and other acute joint problems can also come on with no warning and for no apparent reason, even if you exercise regularly and moderately, and they may recur more easily as well. You may benefit from the expert help of a physical therapist if you develop any of these issues.
To improve your health, you don’t have to reach some unrealistically low body weight. In fact, losing just 10 pounds improves your insulin action, lowers your body’s inflammation, raises your good cholesterol and lowers the bad, and improves your metabolic efficiency. And you can learn how to keep it off for good.
Going on a diet to lose weight isn’t the best long-term solution to managing your body weight or reducing your diabetes risk. Even though you can lose weight on a diet, dieting doesn’t work for most people. It becomes progressively harder to lose weight the longer you stay on a diet, which makes it harder for you to stay motivated to follow it. Consequently, many people give up after they’ve been on a diet for a while, and they fail to meet their target weight loss.
So how can you lose weight? The best way is slowly, over time, accomplished by doing physical activities and cutting back on your calories by a small amount. You won’t even realize that you’re “dieting” while you’re doing it. Just don’t diet or severely restrict your calories without being active, or you’ll lose too much of your muscle and likely eventually end up fatter than you were before. Consider consulting with a registered dietitian to set up an individualized, weight-reducing meal plan for you.
Keep in mind that what you normally weigh can change gradually over your lifetime. But your body has a preferred weight, and when you try to change that quickly by dieting, your body resists the effort to keep it off. If you do daily physical activity while you’re losing weight and after, you’ll be less likely to gain fat back later because you keep more muscle.
The biggest problem with dieting without exercise is that even if you do lose some weight, you’re not likely to keep off it. More than 90 percent of dieters who have successfully lost weight ultimately regain the pounds they struggled to lose. If you go back to eating the same foods that you ate prior to your weight loss, you are likely to return to your previous weight
Regaining the weight is probably even worse for your health than never losing it in the first place. A greater percentage of the weight you gain back is fat (unless you’re exercising a whole lot and gaining muscle). In most cases, you end up with more total body fat than if you had never lost any weight, even if your weight only goes back to your pre-diet level. In other words, you ultimately end up even fatter from dieting.
Keeping off the weight you lost for more than six months is very uncommon even among successful dieters. If you’re one of those people, congratulations. If not, you can benefit from looking at how others have done it. If you lose weight rapidly, you are more likely to gain it back.
How can you become one of the success cases? Some people have figured it out. The National Weight Control Registry has tracked over 10,000 individuals who have lost at least 30 pounds and kept the weight off for at least a year. What method or weight loss plan people use to lose weight doesn’t appear to matter; their food choices ranged from conventional lower-calorie, moderate-carbohydrate diets like Weight Watchers and Jenny Craig to low-carbohydrate ones like Atkins and South Beach. What matters more are the lifestyle habits that almost all of them adopt:
Conversely, those who regain the most weight take in more calories, eat more fast foods and fat, and are less physically active.
Most people fail to prevent weight gain that typically comes with getting older. Also, the greater release of insulin you get from eating excessive amounts of carbohydrate may cause you to gain body fat. Carbohydrates are usually converted into and stored as fat when you’re sedentary, but not so much so when you’re active.
Remember, what matters more is whether you’re fit. Simply get physically active and don’t worry about maintaining a specific weight. Despite the hundreds of thousands of calories you typically eat each year, your body has the innate ability to match food intake with calorie intake and can maintain your body weight within a pound or two. Likely, the biggest contributor to weight gain is burning too few calories in daily movement.
You can prevent or reverse weight gain over time by making small changes in your daily habits. A pound of fat equals about 3,500 calories, so if you eat just 50 more calories than you use each day (the equivalent of less than a quarter cup of cooked rice), you can gain 5 pounds of body fat in a year from that alone. If you cut back by 50 calories instead — by leaving a few bites uneaten or skipping a small treat — and expend an extra 50 calories a day by doing some extra walking, stretching, or other easy activity, you can lose 10 pounds of body fat in a year instead. Choose to tip the scale in your favor.
Exercising causes you to retain and gain some muscle mass, which is what you want to have happen given that muscle is sensitive to insulin and is a storage place for carbohydrates and blood glucose. Muscle is denser than body fat and weighs more. When you lose fat while gaining muscle, your scale weight may change very little (or even rise slightly at first), even though your total fat percentage is getting lower.
If you feel compelled to weigh yourself frequently after you start an exercise program, don’t. Focus on your waist and hip measurements and how your clothes fit instead — the so-called clothes test. When you’re starting your activity program, only weigh yourself once a week at the same time of day. Even if exercising regularly doesn’t make you lose all the weight you want to, it can still help you lose your fat and keep your muscle.
Taking insulin can potentially lead you into gaining weight if you don’t manage its use well. You can adopt some strategies to keep weight gain from happening whether you have type 1 or type 2 diabetes. Some other diabetes medications can contribute to fat gains as well. Luckily, some newer medications can help you lose weight. You may want to talk with your doctor about using them and avoiding the ones that cause weight gain if you want to get thinner.
Why is using insulin sometimes associated with weight gain? On insulin, your blood glucose is (usually) in a tighter range, and you stop losing some calories as glucose in your urine. You may also gain weight from having to eat extra to treat any lows caused by using insulin.
Most people diagnosed with type 1 diabetes gain some weight as soon as they start using insulin. Many of them lost weight before diagnosis — some of it muscle — so not all the weight regain is necessarily bad.
However, you can gain excess weight from taking too much daily insulin and then needing extra carbohydrates to treat low blood glucose. You can also gain weight if you’re taking the right dose of insulin to cover your food and you’re simply eating too many calories. In any case, gaining fat weight from insulin can lead to “double diabetes,” meaning that you can become more insulin resistant like many with type 2 diabetes and need larger insulin doses. People with type 1 may need lower insulin doses if they’re active.
Readjusting the ratio of basal to meal-associated insulin — specifically, lowering your basal doses and raising your pre-meal insulin — without increasing your total daily insulin dose may prevent weight gain if you have type 1 diabetes.
What else can you do to avoid weight gain with insulin? First of all, try to keep your insulin needs as low as possible because the more you take, the greater your potential for weight gain is. The best way to keep your insulin needs in check is to engage in regular physical activity. For example, some people with type 2 diabetes who were studied gained weight from insulin use while others didn’t. The main difference between them was that the gainers were less physically active. Although taking insulin doses that effectively manage blood glucose can also lead to weight gain in type 1 diabetes, being more active can prevent it.
During any physical activity, your muscles can take up blood glucose and use it as a fuel without insulin. Following exercise, your insulin action is heightened for a few hours up to 72 hours. During that time, you need smaller doses of insulin to have the same effect.
You may be able to avoid weight gain by looking at the type of insulins you’re using. For example, once-daily Levemir used by people with type 2 diabetes causes less weight gain and less frequent hypoglycemia than N insulin, even combined with use of rapid-acting injections of meal insulin. The same is likely true when using Lantus, Basaglar, Toujeo, and Tresiba. In type 1 diabetes, individuals end up eating less when using Levemir compared to Lantus, leading them to gain less weight. (Chapter 3 has the lowdown on these and other insulins.)
Table 15-1 breaks down how common insulins can impact weight gain. You may be able to avoid weight gain from insulin taken for meals just by altering when you take it (before vs. after eating), as you can see in Table 15-1.

Both the type of insulins you use and the doses you take are important to consider in the overall management of your diabetes and your body weight. Making sure that your doses are regulated effectively helps prevent blood glucose lows and highs.
Even when you begin exercising more, your non-insulin medications may be working against your ability to lose weight. Focus on reducing diabetes medications that contribute to weight gain and replacing them (if needed) with ones that are weight-friendly — that is, they don’t affect body weight, they help with weight loss, or they cause less weight gain. Table 15-2 shows both categories of medications; you can read more about each type of medication in Chapter 3.

When you lose excess body fat, you can potentially let loose a lifetime of accumulated toxins stored in your fat, like PCBs and DDEs from insecticides. These substances can lead to nerve damage and are the main reason why losing weight when you’re older may not be that good for you. Another reason is the increased risk of fracturing a hip, getting frail, and being admitted to a nursing home because you no longer have the strength to care for yourself. This scenario can happen if you lose too much of your muscle and strength from dieting when you’re older.
Along with toxins, any medications stored in fat are released during weight loss. Unless your doctor lowers the dose of fat-soluble medications you’re on when you’re losing weight, you may end up with higher than normal or advisable amounts in your bloodstream.
If you’ve done the yo-yo dieting thing (cycling between losing and gaining weight), you can end up losing so much of your muscle that you’re too weak to move your own body weight. That makes you “fat frail” (known as sarcopenic obesity in the medical world). Having too little strength can greatly lower your quality of life. What’s more, losing too much muscle lowers how many calories you need daily, making it easier to gain weight even when eating the same number of calories as you used to. It’s a vicious cycle.
Many people with diabetes or prediabetes who have body weight issues are more prone to suffering from emotional disorders like depression and anxiety, along with body image issues. True clinical depression is much different from the occasional bout of “the blues.” Depression lasts much longer, often going on for months without any lasting relief.
When depressed, you may feel sad and hopeless and lose interest in things you normally enjoy. Other symptoms include eating or sleeping unusual amounts (whether that’s more or less), feeling low in energy, having trouble concentrating, and having negative feelings about yourself.
Having diabetes makes you more than twice as likely to suffer from the most serious form of depression, major depressive disorder. Almost half of all people with diabetes have some level of depression, and it’s even more likely if you have heart disease, arthritis, or other health issues. Feeling blue can sabotage your usual diabetes care because you may not feel like being active or making healthful food choices, and it may even lead you to binge eat, gain more weight, and feel even worse about yourself. If you haven’t had a reason to smile today, try to find one.
Getting adequate sleep each night helps you burn fat and lose weight. Too little sleep increases levels of the hormone cortisol, which contributes to belly fat, insulin resistance, and type 2 diabetes. And losing sleep can even keep you from losing weight when you’re dieting.
In a study, middle-aged adults who slept 8.5 hours per night lost about 3 pounds in two weeks, but those sleeping only 5.5 hours per night lost less than half that much. On top of that, sleeping less lowered the proportion of fat weight lost by 55 percent. The sleep-deprived adults felt hungrier, and their bodies used less energy during the day to compensate for lack of sleep.
Unfortunately, sleeping well isn’t as easy as it sounds. Aging causes you to sleep less deeply and more fitfully. The normal aches and pains of aging can keep you awake at night, or you may have medical conditions that make it harder to get enough deep sleep. Many people with diabetes suffer with sleep apnea, which can result in greatly disturbed sleep patterns.
Aging also leads to lower levels of a natural body hormone called melatonin, which is related to falling and staying asleep. Melatonin comes from the pineal gland in the brain and controls your sleep and wake cycles. These naturally decreased levels lead to greater insulin resistance. Taking over-the-counter melatonin supplements 30 minutes before you go to bed may help you sleep better and lower your morning blood glucose as well.
