Sous vide chicken and sautéed sugar snap peas. Chicken is a good source of high biologic value protein.
P.D. Mangan makes an argument for high-protein diets for those hoping to shed pounds of fat:
In humans, data collected from 38 different trials of food consumption that used widely varying intakes of protein, from 8 to 54% of energy, showed: “Percent dietary protein was negatively associated with total energy intake (F = 6.9, P < 0.0001) irrespective of whether carbohydrate (F = 0, P = 0.7) or fat (F = 0, P = 0.5) were the diluents of protein. The analysis strongly supports a role for protein leverage in lean, overweight and obese humans.”
In obese humans, substitution of carbohydrate with protein leads to far greater weight loss, nearly twice as much.
In a human trial, decreasing the percentage of protein in food from 15% to 10% led to increased calorie intake of 12%. However, increasing the protein percentage from 15 to 25% did not affect calorie intake, which shows that humans may target a certain amount of protein, and eat no more or less when they get it.

Paleo Diabetic 
Eating Paleo helped me lose 55 pounds, get off all but 1 diabetic-related med! My problem that I cannot find an answer to is I have lost the weight with ease but I didn’t weight train or exercise of any kind and I have lost so much muscle that my skin is loose and wrinkly, and people are worried about me saying I look emaciated. I do not have any eating disorders. I just don’t know how to GAIN MUSCLE back and gain healthy weight. I am a 58-year-old female, 5’10”, 144 lbs. Please do you have any guidance as what I can utilize to start towards my goal of muscle? Strong, beautiful muscle, at that! I eat protein every meal and I usually don’t eat many carbs as to keep my blood glucose low. BUT I have been known to give in and wolf down some/many processed carbs. I have done the 21-Day Sugar Detox with great success in killing the sugar monster, but 6 months down the road, I greeted the monster. I just need some guidance on how to start building muscle. I do hope you have the time to comment.
Thank you for your valuable time!
Hi, Merry.
Congratulations on that weight loss!
The only weigh to gain muscle at our ages is to do weight training, aka resistance training, while providing your body with good nutrition and adequate protein (at least 1 mg/kg of ideal body weight, or even 1.5 mg/kg).
Aerobic exercise will not help you build much muscle.
If you don’t know much about weight training, it’s a good idea to get a personal trainer.
Concentrate on The Big Five exercises if your training time is limited (whose isn’t?):
