Nuts Fuel Weight Gain
Nuts are high in unsaturated fats, fiber and micronutrients, and it has been suggested that they can reduce the risk of heart disease. However, a recent study examining the effect of nuts on insulin resistance and in patients with type 2 diabetes found that nuts may also increase weight.
Twenty people participated in the study by eating about 3 ounces of almonds a day for four weeks. Though the nuts did not substantially influence insulin sensitivity, body weight increased significantly, which may have affected changes in insulin sensitivity. Cholesterol, both good (HDL) and bad (LDL), decreased significantly after the four-week period.
In patients with diabetes, the increase in almonds did not alter blood sugar control.
The study suggests that in order to avoid weight gain, nuts must replace other sources of energy and fat in the diet.

Like most whole foods, nuts can have important health benefits. However, they clearly need to be used sparingly if you are one of the 65 percent of Americans who are overweight.
Also, nuts are high in omega-6 fats so if you are not supplementing your diet with fish oils it is likely your omega 6:3 ratio is about 15:1 rather than the ideal 1:1.
Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking ...
